The rak_wismesh_tap_v2-tft link failed on CI with "sh: Argument list too
long": the device-ui bump in #11214 grew the MUI object list enough that
the linker command line crossed the kernel exec arg limit (this env's long
name lengthens every object path, so it tipped first).
extra_scripts/ld_response_file.py already solves this for esp32p4; promote
it to esp32_common so every ESP32 target links through a response file,
and drop the now-inherited entry from esp32p4.ini.
Verified by building rak_wismesh_tap_v2-tft at the failing commit plus this
fix: links clean (macOS's exec arg limit is smaller than the Linux one that
tripped CI, so an unwrapped link could not have passed).
sendLog() notified once per firmware log line with no backpressure. With
debug_log_api_enabled and a subscribed client, a logging burst drains the
msys_1 mbuf pool that every GATT notification and ATT response allocates
from, so ble_gatts_notify_custom starts returning BLE_HS_ENOMEM (rc=6) --
for the fromNum doorbell too, not just the log line that exhausted it.
Each failure then prints an error over serial at ~12ms apiece, which is
itself enough to throttle the main loop during a burst.
Register a callback on the log characteristic so the host's own
ERROR_GATT verdict pauses log notifies for 250ms and lets the pool
refill. Keying off the failure rather than a free-block count keeps this
correct however the pools are sized.
Also restore CONFIG_BT_NIMBLE_MSYS_1_BLOCK_COUNT to the IDF default of
12. Pool selection is by block size and a notify request always resolves
to the smallest pool, so msys_1 is the only pool GATT draws from; 8 was
thin once anything chains or fragments. msys_2 and the ACL/EVT transport
pools are left trimmed -- neither is on the notify path, and restoring
the full defaults would re-spend the contiguous allocation that #10741
was fixing on heap-tight boards.
sendLog() also lacked the null check onNowHasData() already has, so a log
line arriving during BLE teardown dereferenced a freed characteristic.
Fixes#11245
Range test is excluded on every target as of 2.8, so set
MESHTASTIC_EXCLUDE_RANGETEST=1 globally in [env] build_flags and drop the
now-redundant per-variant flags from esp32, rak11200 and stm32.
Guard RangeTestModule.cpp with the same condition used in Modules.cpp so the
translation unit compiles to nothing rather than relying on --gc-sections to
strip it, and always report RANGETEST_CONFIG in the device metadata
excluded_modules bitmask so clients hide the config.
${platformio.packages_dir} resolves to a backslash path on Windows.
PlatformIO parses build_flags with POSIX shell rules, which strip the
backslashes and turn the NimBLE include paths into broken relative
paths (d:platformiopackages/...), failing the build with
'host/ble_gap.h: No such file or directory'. Quoting the flags
preserves backslashes through parsing.

Audit of the XEdDSA packet-signing implementation (#10478) surfaced several
issues in when unsigned packets are accepted on receive or emitted on send.
This fixes them and adds regression coverage.
- Unicast NodeInfo exchange no longer breaks against signer nodes: the
NodeInfoModule downgrade drop is gated to broadcasts, since senders never
sign unicast (want_response replies, directed exchanges).
- Replace the payload-size sign heuristic with an exact encoded-size gate
(signedDataFits) and mirror it on the receive side, removing a dead band
where 167-168 B broadcasts were signed then failed TOO_LARGE.
- Extract the receive policy into checkXeddsaReceivePolicy() and apply it to
plaintext-MQTT decoded downlink, which previously skipped signature
verification and downgrade protection entirely.
- Reject signatures whose length is neither 0 nor 64 as malformed, so a
crafted partial signature can't inflate the size estimate and dodge the
unsigned-downgrade drop.
- Hold cryptLock on the MQTT verify path (shared Ed25519 key cache).
- Clear any client-preset signature on packets we originate, on all builds.
- Randomized (hedged) signing per the Signal XEdDSA spec: bump the
meshtastic/Crypto pin to the build where XEdDSA::sign mixes 32 bytes of
caller randomness into the nonce as Z (meshtastic/Crypto#3), and seed those
bytes in xeddsa_sign from HardwareRNG (checked, with a seeded-CSPRNG
fallback). test_crypto pins that repeated signs differ and both verify.
Adds test coverage: test_packet_signing groups A-E (receive matrix, send
policy, NodeInfo backstop, encoding invariants, decoded-ingress policy),
test_mqtt end-to-end downlink cases, and a test_crypto randomization check.

- Delete unused clearNVS() (no callers; should have been removed in #10264).

* Update crypto commit hash
* Some fixes for xeddsa pr (#9610)
* fix: add null check for getMeshNode() in NodeInfoModule
getMeshNode() can return nullptr for unknown nodes. Dereferencing
without a check crashes the firmware when receiving NodeInfo from
a node not yet in the database.
* fix: enforce XEdDSA signature verification and prevent stripping
Previously, failed signature verification still allowed the packet
through, making signatures purely cosmetic. Now:
- Failed verification drops the packet (DECODE_FAILURE)
- Successfully verified nodes get HAS_XEDDSA_SIGNED bitfield set
- Unsigned packets from previously-signing nodes are rejected
- Log levels reduced from WARN/ERROR to DEBUG/WARN as appropriate
* fix: include packet metadata in XEdDSA signature
The signature now covers [fromNode | packetId | portnum | payload]
instead of just the payload bytes. This prevents:
- Replay attacks (different packetId fails verification)
- Reattribution (different fromNode fails verification)
- Portnum redirection (different portnum fails verification)
Also adds a key initialization check to xeddsa_sign (returns false
if XEdDSA keys are all zeros) and checks the return value in the
encode path.
* fix: handle existing key pair in AdminModule security config
When a user provides both a valid private key and public key via
admin config, the crypto engine's DH private key and owner public
key were never loaded. DMs and XEdDSA signing would silently break.
Add an else branch to load both keys into the crypto engine.
* perf: cache Ed25519 public key conversion in xeddsa_verify
curve_to_ed_pub() performs field element parsing, inversion, and
multiplication on every call. Since packets from the same node
tend to arrive in bursts, a single-entry cache avoids repeating
this expensive conversion for consecutive packets from one sender.
* fix: skip identity cleanup when node number is unchanged
createNewIdentity() was called on every generateCryptoKeyPair(),
including normal boots where the same key is regenerated. This
caused unnecessary NodeDB writes and old-node cleanup logic to
run when the node number hadn't actually changed.
Also fixes only zeroing byte[0] of the old node's public key
instead of clearing the entire array.
* fix: replace hardcoded 120 with derived XEDDSA_SIGNATURE_SIZE constant
The payload size check for XEdDSA signing used a magic number (120).
Replace with a derivation from DATA_PAYLOAD_LEN and XEDDSA_SIGNATURE_SIZE
so the limit adjusts automatically if constants change. This also
increases the max signable payload from 120 to 169 bytes, which is
still safe since the actual encoded size is checked after pb_encode.
* fix: add const qualifiers to XEdDSA verify and curve_to_ed_pub inputs
pubKey, payload, and signature parameters in xeddsa_verify are
input-only and should not be modified. Same for curve_pubkey in
curve_to_ed_pub.
* chore: remove commented-out old Crypto dependency in portduino.ini
* Leave out the admin module change for now

* feat: add Nordic nRF54L15-DK variant (Zephyr + BLE + LoRa)
Adds a community hardware variant for the Nordic nRF54L15-DK (PCA10156)
with an external EBYTE E22-900M30S (SX1262) LoRa module. First Meshtastic
port running on the Zephyr RTOS; all other Nordic targets use the nRF5
SoftDevice stack.
Scope
-----
- New Zephyr-based platform layer under src/platform/nrf54l15/ providing
Arduino-compatible shims (Arduino.h, SPI, Wire, Print, Stream) over the
Zephyr APIs plus a LittleFS-backed InternalFileSystem on SPIM20.
- Bluetooth LE peripheral (NRF54L15Bluetooth.*) built on the Zephyr BT
host stack, exposing the Meshtastic GATT service with legacy
connectable advertising, just-works pairing, dynamic MTU exchange
(up to 247 bytes), and iOS connection-parameter tweaks.
- Variant directory variants/nrf54l15/nrf54l15dk/ with pin map for the
E22 module on connector J1, PlatformIO env (nrf54l15dk), Zephyr
DT overlay and a wiring README.
- Zephyr project config (zephyr/prj.conf + board overlay) tuned for
BT + LoRa: 16 KB main stack, 4 KB BT RX thread, RTT logging in
immediate mode, newlib-nano heap sized to leave room for the GATT
pools while still allowing ATT MTU=247.
- extra_scripts/nrf54l15_linker.py works around a PlatformIO + old Ninja
issue where Zephyr's two-pass linker script generation does not run
automatically; the post-script parses build.ninja and invokes the
gcc -E step directly before the final link.
- boards/nrf54l15dk.json board definition (PlatformIO needs it for the
DK; the Seeed platform only ships the XIAO variants).
- variants/rp2350/rp2350.ini excludes platform/nrf54l15/ from RP2350
build_src_filter so the shared platform tree does not leak between
targets.
- .gitignore: add nRF J-Link / RTT debug artifacts (flash.jlink,
rtt_*.txt).
Shared source changes
---------------------
- src/main.{cpp,h}, src/RedirectablePrint.cpp, src/FSCommon.{cpp,h},
src/mesh/{Channels,NodeDB,RadioLibInterface,MeshService,PhoneAPI}.cpp,
src/mesh/RadioLibInterface.h, src/modules/AdminModule.cpp: add small
guards / helpers so the Zephyr build compiles alongside the Arduino
targets. Behavior on existing boards is unchanged.
Hardware model
--------------
HW_VENDOR maps to meshtastic_HardwareModel_PRIVATE_HW until a dedicated
protobuf enum value is assigned upstream. The variant declares
custom_meshtastic_hw_model = 132 so the maintainers can wire the new
enum value through the protobufs repo after merge.
Hardware note
-------------
The E22-900M30S does not connect its DIO2 pin to TXEN internally — a
wire/solder bridge between DIO2 and TXEN on the module is required for
TX to work. Details and full pin map are in the variant README.
Validation
----------
Built clean against develop. On real hardware (April 2026) the port
passes end-to-end: iOS companion app pairs and connects, configuration
round-trip works, LoRa TX/RX reaches a canonical tbeam on the same mesh
channel, NodeDB updates propagate both ways, and traceroute completes.
* fix(nrf54l15): use atomic fs_rename instead of copy fallback
Zephyr LittleFS on nrf54l15 supports fs_rename natively, so route it
through the same atomic path as ESP32. The previous copyFile+remove
fallback truncated the destination before copying, leaving 0-byte files
if interrupted mid-write.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(nrf54l15): expand storage_partition from 36KB to 700KB
LittleFS on the default 9-block (36KB) storage_partition ran out of
space during copy-on-write of config.proto, causing fs_write to return
ENOSPC and pb_encode to surface "io error" when saving configuration
via the mobile app.
Reclaim slot1_partition (the MCUboot secondary slot — unused since we
flash directly via J-Link) and grow storage_partition to span
0xb6000..0x165000 (~175 blocks).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(nrf54l15): drop USERPREFS_LORACONFIG_* so LoRa config stays mutable
NodeDB rewrites LoRa config from USERPREFS_LORACONFIG_* on every boot,
which prevented reconfiguration via the BLE/serial app. Drop the
variant-level defaults; users configure region and modem preset through
the app like every other variant.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(nrf54l15): enforce MITM passkey pairing on GATT service
- Add MESH_PERM_READ/MESH_PERM_WRITE macros (READ_AUTHEN/WRITE_AUTHEN)
on all mesh service characteristics so clients must complete passkey
exchange before accessing fromNum/fromRadio/toRadio/logRadio.
- Wire FIXED_PIN mode to bt_passkey_set() so the device advertises a
known PIN (config.bluetooth.fixed_pin); RANDOM_PIN keeps default
per-pairing random passkey.
- Reduce BleDeferredThread HARD_WATCHDOG_MS from 3min to 1min.
- prj.conf: CONFIG_BT_SMP_ENFORCE_MITM=y, CONFIG_BT_FIXED_PASSKEY=y,
CONFIG_BT_SMP_SC_PAIR_ONLY=n (legacy fallback for clients that abort
SC pairing with reason 0x01 within 150ms).
* fix(nrf54l15): resolve develop-merge conflict + cppcheck warnings
The `Merge branch 'develop'` left two ~RadioLibInterface() declarations
in src/mesh/RadioLibInterface.h: the inline version added upstream by
PR #10254 (which independently applied the same UAF guard this PR was
carrying) and the out-of-line version this PR introduced. GCC rejects
the duplicate, breaking every platform build. Drop the out-of-line
declaration + definition; keep upstream's inline form.
Also silence the 13 cppcheck low warnings introduced by the new
nrf54l15 Arduino shim — Arduino's `String`/`SPISettings` API contract
relies on implicit single-arg constructors used pervasively by
existing Meshtastic code, so suppress `noExplicitConstructor` inline
with a comment instead of breaking the API. The few mechanical wins
(`const tmp[2]`, `const uint32_t *sp`) are applied directly.
* fmt: fix Trunk Check lint issues on nrf54l15-port
- extra_scripts/nrf54l15_linker.py: move regular imports above
Import("env") to silence E402, add trunk-ignore-all(F821) for the
PIO/SCons SConstruct injection (matches esp32_pre.py / nrf52_extra.py
convention)
- src/platform/nrf54l15/NRF54L15Bluetooth.cpp: clang-format 16.0.3
- boards/nrf54l15dk.json + variants/nrf54l15/nrf54l15dk/README.md:
prettier 3.8.3 (also resolves markdownlint MD060 on README tables)
No behavior change.

* fix(nrf54l15): address Copilot review comments + correct clang-format style
Six review threads from the 2026-04-30 Copilot review:
- src/platform/nrf54l15/nrf54l15_main.cpp: validate PSP against the nRF54L15
SRAM range (0x20000000..0x20040000) and 4-byte alignment before walking the
faulting thread's stack, and clamp the walk so it never reads past the end
of RAM. Prevents a second fault inside the fatal handler when PSP is
corrupted (common in real faults).
- src/platform/nrf54l15/nrf54l15_arduino.cpp: gate the bring-up printk traces
in digitalWrite/digitalRead (CS/NRESET toggle log, BUSY-before-NRESET
snapshot, BUSY periodic timeline) behind a new -DNRF54L15_GPIO_DEBUG flag
that is off by default. The "dev NOT READY" message stays unconditional —
it indicates a genuine hardware/DTS misconfig.
- src/modules/AdminModule.cpp: don't mutate config.device.output_gpio_enabled
from handleGetConfig(). Reflect the live pin state in the response payload
only — a getter must not write back to disk-persisted state.
- src/platform/nrf54l15/InternalFileSystem.h: derive totalBytes() from
FIXED_PARTITION_SIZE(storage_partition) at compile time so it tracks the
DK overlay's ~700 KB partition instead of the stale 36 KB hard-coded value.
Updated the file header comment accordingly.
- extra_scripts/nrf54l15_linker.py: make _extract_gcc_command() handle the
POSIX Ninja COMMAND format (no `cmd.exe /C "..."` wrapper) in addition to
the Windows form, so the script doesn't hard-fail on Linux/macOS hosts.
- src/platform/nrf54l15/NRF54L15Bluetooth.cpp: clamp NO_PIN to RANDOM_PIN
with a one-shot LOG_WARN. The mesh GATT permissions are declared with
BT_GATT_PERM_*_AUTHEN and prj.conf sets CONFIG_BT_SMP_ENFORCE_MITM=y, so
NO_PIN with no auth callbacks would leave every characteristic returning
BT_ATT_ERR_AUTHENTICATION. Falling back to RANDOM_PIN keeps the link
usable instead of silently broken. Also re-formatted this file with the
project's .trunk/configs/.clang-format (Linux braces, 4-space indent,
130-col) — the previous lint-fix commit a2aca3234 accidentally used the
default LLVM style here, which CI's clang-format would have rejected.
Build verified: pio run -e nrf54l15dk passes, RAM 47.4%, Flash 28.6%.

* fix(nrf54l15): address remaining Copilot review threads
Round 2/3 review fixes — bugs first, then docs/portability:
BLE concurrency (NRF54L15Bluetooth.cpp):
- onNowHasData / sendLog / BleDeferredThread / shutdown: acquire
active_conn under ble_mutex via new acquire_active_conn() helper so
disconnected_cb can't free the conn between the null check and
bt_conn_ref/bt_gatt_notify (use-after-unref).
- write_toradio: reject writes that exceed MAX_TO_FROM_RADIO_SIZE with
ATT_ERR_INVALID_ATTRIBUTE_LEN instead of returning success and silently
dropping the payload (would hide failed config writes from the phone).
- start_advertising: truncate the device name to fit the 31-byte legacy
scan-response limit and switch to BT_DATA_NAME_SHORTENED so
bt_le_adv_start() doesn't reject the payload when the name approaches
CONFIG_BT_DEVICE_NAME_MAX=32.
Linker / portability:
- main.h: drop the rp2040Loop() forward declaration that had no
definition and no callers — would surface as a link error if any RP2040
build added a call to the symbol.
- nrf54l15_arduino.cpp: transfer16() now uses static __aligned(4) DMA
buffers (matching transfer()), removing the EasyDMA-reachability hazard
of caller-stack buffers on this part.
Filesystem (InternalFileSystem.h):
- usedBytes(): return real usage from fs_statvfs() instead of 0 so OTA
/ range-test free-space guards work.
- rewindDirectory(): close the dir before reopening — Zephyr fs_dir_t has
no rewind, and re-fs_opendir on an open handle leaks LittleFS state.
Crash handler (nrf54l15_main.cpp):
- After the stack walk, busy-wait 50 ms to flush RTT/printk and call
sys_reboot(SYS_REBOOT_COLD) directly so the saved_crash record is
actually reported on the next boot. Default Zephyr config has
RESET_ON_FATAL_ERROR=n, so the previous k_fatal_halt() spun forever.
Generalization / config:
- PhoneAPI.cpp: replace the NRF54L15_DK ifdef with a
MESHTASTIC_EXCLUDE_FILES_MANIFEST capability flag (defined in the
nrf54l15dk env) so future variants can opt in/out without touching
shared code.
- variants/nrf54l15/nrf54l15.ini: parameterize libdeps include paths via
${PIOENV} so additional nRF54L15 envs sharing nrf54l15_base don't break.
- prj.conf: drop the stale "36 KB storage_partition" comments — the DK
overlay reclaims slot1 to ~700 KB and runtime size comes from
FIXED_PARTITION_SIZE.
- nrf54l15dk overlay: remove the zephyr,console / zephyr,shell-uart
chosen entries that conflicted with CONFIG_UART_CONSOLE=n + RTT
console; keep uart30 enabled so swapping the console is one Kconfig
flip away.
Build: nrf54l15dk SUCCESS (flash 28.6%, RAM 47.4%); wiznet_5500_evb_pico2
SUCCESS (verifies the shared main.h change).

* fix(nrf54l15dk): use PRIVATE_HW (255) for custom_meshtastic_hw_model
Per @thebentern's review: the nRF54L15-DK is a development kit, not a
canonical Meshtastic SKU, so it falls under HardwareModel::PRIVATE_HW
(255) — the same enum value already used at runtime via HW_VENDOR. The
placeholder 132 is removed; no dedicated enum number will be assigned
for DK boards. Slug stays NRF54L15_DK as a human-readable identifier.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(nrf54l15): unstarve bt_long_wq so SC pairing completes
bt_pub_key_gen() runs the ECC P256 key generation on bt_long_wq. At default
prio=10 (preemptible) and stack=1400 it gets starved by Meshtastic app
threads at boot — sc_public_key stays NULL for minutes, smp_public_key()
defers with SMP_FLAG_PKEY_SEND, and every SC pairing attempt stalls right
after the public-key exchange. iOS shows "Connecting…" forever with no
PIN prompt; bleak/CLI fails the first CCC notify write with
"Protocol Error 0x05: Insufficient Authentication".
Set CONFIG_BT_LONG_WQ_PRIO=0 (highest preemptible, ties with main) and
CONFIG_BT_LONG_WQ_STACK_SIZE=4096 (margin for the P256M driver frames).
Validated E2E with iOS Meshtastic app: bt_smp_pkey_ready fires within ~40 s
of boot, 20 SC Passkey Entry rounds complete with matching pcnf/cfm,
encrypt 0x01 / sec_level 0x04 (Authenticated MITM), bonded=1.
* feat(nrf54l15): hardware I2C bus via TWIM30 + sensor telemetry
Adds the Arduino TwoWire layer for the nRF54L15-DK so Meshtastic's
sensor drivers can talk to external I2C devices over the hardware
TWIM30 peripheral.
Bus binding:
- &uart30 disabled in the board overlay (peripheral instance 30 is
shared between UARTE30 / TWIM30 / SPIM30 — pick one). Console stays
on RTT via CONFIG_RTT_CONSOLE.
- New i2c30_default / i2c30_sleep pinctrl with SDA=P0.03 / SCL=P0.04.
External 4.7 kOhm pull-ups required on both lines.
- &i2c30 enabled at I2C_BITRATE_FAST (400 kHz).
- button_3 (SW3, P0.04) deleted from DTS so the pad can be claimed by
i2c30 pinctrl; SW3 is still wired to the pad on the DK, do not press
it during I2C use or it will short SCL to GND.
Arduino layer:
- src/platform/nrf54l15/Wire.cpp resolves the DT node at compile time
via DEVICE_DT_GET(DT_NODELABEL(i2c30)) and dispatches Arduino's
beginTransmission / write / endTransmission / requestFrom to
i2c_write / i2c_write_read / i2c_read. Buffer is sized to 256 bytes
for forward compatibility with the SE050 secure element on the
custom PCB.
- Wire.h drops the prior compile-only stubs and exposes the real
TwoWire surface.
- Arduino.h: BitOrder becomes an enum (not #define) so Adafruit_BusIO's
`typedef BitOrder BusIOBitOrder;` compiles.
Variant + build flags:
- nrf54l15.ini flips HAS_WIRE / HAS_SENSOR / HAS_TELEMETRY from 0 to 1
and cherry-picks the sensor libs Meshtastic needs (BusIO, Sensor,
BMP280, BME280, INA219/226/260/3221, SHT4X). The full
environmental_base group is avoided because it pulls
Adafruit_SSD1306 / Adafruit_GFX which rely on Arduino pin macros the
Zephyr shim does not implement.
- nrf54l15dk variant.h defines PIN_WIRE_SDA / PIN_WIRE_SCL for parity
with the Arduino convention used by other variants. The actual bus
wiring is fixed by the overlay pinctrl above.
Validated 2026-05-14/15 on the DK with BMP280 @ 0x76 (temperature +
barometric pressure) and INA3221 @ 0x42 (rail voltage / current);
EnvironmentTelemetry / PowerTelemetry packets transmit successfully
over LoRa.
Footprint cost on nrf54l15dk: +45 KB flash, +1.7 KB RAM.
* feat(nodedb): honor USERPREFS for environment telemetry on first boot
installDefaultConfig() now respects two new compile-time prefs:
USERPREFS_CONFIG_ENV_TELEM_UPDATE_INTERVAL
USERPREFS_CONFIG_ENVIRONMENT_MEASUREMENT_ENABLED
The mobile apps enforce a 30 min floor on environment_update_interval
in the settings UI, which makes short-interval bring-up testing of new
sensor hardware painful — you have to wait half an hour for the first
LoRa packet to confirm wiring + driver. With these prefs baked into
the variant, the firmware can ship a freshly-flashed device that
broadcasts on a shorter cadence (e.g. 900 s) the moment storage_partition
is empty.
Both prefs are gated on #ifdef so the behavior is unchanged for any
variant that does not opt in. Documented in userPrefs.jsonc with the
existing telemetry-interval pref block.
* fix(nrf54l15): allow multiple bonded BLE peers
CONFIG_BT_MAX_PAIRED defaults to 1, so once the first peer (e.g. an
iOS phone) has paired and bonded, every subsequent pairing attempt
from a different MAC fails inside bt_keys_get_addr() with no free
key slot — the host returns BT_SECURITY_ERR_KEY_DOES_NOT_EXIST and
the second peer never gets past SMP.
Raise the slot count to 4 so the device can simultaneously hold an
iOS phone, a Windows host, a Linux host, and one spare bond. Add
BT_KEYS_OVERWRITE_OLDEST so that once the table fills, the LRU peer
is evicted on the next pairing rather than rejecting the new peer.
This matches the behavior other Meshtastic ports already provide
(nRF52 uses CONFIG_BT_PERIPHERAL_PRIO_CONN with similar semantics).
Discovered while bringing up the Python CLI on Windows alongside
the existing iOS bond.
* fix(nrf54l15): zero-initialize TwoWire buffers + clang-format Wire
cppcheck on every CI target (esp32s3, rp2040, rp2350, nrf52840, ...) was
failing the build with two `uninitMemberVar` warnings on TwoWire's
constructor: `txBuf` and `rxBuf` (256-byte arrays) were not initialized.
Even though the buffers are only read after txLen/rxLen is set, leaving
them uninitialized is a footgun if any future caller bypasses the
len-set step. Use C++11 value-initialization in the member initializer
list — costs ~512 B of memset at boot, gains a clean cppcheck pass and
defensive-against-future-changes semantics.
Also reformat Wire.{cpp,h} with the project's `.trunk/configs/.clang-format`
config so the Trunk Check Runner passes — clang-format moved the
`<errno.h>` include before the Zephyr-namespaced ones in Wire.cpp and
collapsed two inline overloads to single lines in Wire.h.
* fix(AdminModule): remove dead OUTPUT_GPIO_PIN/GpioOutputModule references
OUTPUT_GPIO_PIN is never defined and modules/GpioOutputModule.h doesn't
exist in the codebase; all #ifdef OUTPUT_GPIO_PIN branches were dead code
introduced by the nRF54L15-DK variant commit. Strips the include, the
output_gpio_enabled OFF→ON/ON→OFF transition logic in handleSetConfig(),
and the digitalRead() reflection in handleGetConfig().

To save resources, some devices where LR11x0 was never an option
excluded it from compilation, using RADIOLIB_EXCLUDE_LR11X0 .
As we will soon have LR2021 support, apply the same treatment
to that chip to these devices, by adding RADIOLIB_EXCLUDE_LR2021
This reverts commit 391928ed08.
Since esp32_https_server commit e2c9f98, this is no longer necessary.
Also, the esp32-common.ini '-include mbedtls/error.h' causes a build error
under IDF v5 (https://github.com/meshtastic/firmware/pull/9122#issuecomment-4185767085):
<command-line>: fatal error: mbedtls/error.h: No such file or directory
so this change fixes that error.
We cache and dedupe our dependencies, referring to them with multiple methods/urls is just noise.
