8fe12e9fda Fix W5100S socket exhaustion blocking MQTT and additional TCP clients (#9770)
The W5100S Ethernet chip has only 4 hardware sockets. On RAK4631
Ethernet gateways with syslog and NTP enabled, all 4 sockets were
permanently consumed (NTP UDP + Syslog UDP + TCP API listener + TCP
API client), leaving none for MQTT, DHCP lease renewal, or additional
TCP connections.

- NTP: Remove permanent timeClient.begin() at startup; NTPClient::update()
  auto-initializes when needed. Add timeClient.end() after each query to
  release the UDP socket immediately.
- Syslog: Remove socket allocation from Syslog::enable(). Open and close
  the UDP socket on-demand in _sendLog() around each message send.
- MQTT: Fix socket leak in isValidConfig() where a successful test
  connection was never closed (PubSubClient destructor does not call
  disconnect). Add explicit pubSub->disconnect() before returning.

8fa5b4f7ce Fix: Enable touch-to-backlight on T-Echo (not just T-Echo Plus) (#9953)
The touch-to-backlight feature was gated behind TTGO_T_ECHO_PLUS, but
the regular T-Echo has the same backlight pin (PIN_EINK_EN, P1.11).
This changes the guard to use PIN_EINK_EN only, so any device with an
e-ink backlight pin gets the feature.

948c28afff fix: MQTT settings silently fail to persist when broker is unreachable (#9934)
* fix: MQTT settings silently fail to persist when broker is unreachable

isValidConfig() was testing broker connectivity via connectPubSub() as
part of config validation. When the broker was unreachable (network not
ready, DNS failure, server down), the function returned false, causing
AdminModule to skip saving settings entirely — silently.

This removes the connectivity test from isValidConfig(), which now only
validates configuration correctness (TLS support, default server port).
Connectivity is handled by the MQTT module's existing reconnect loop.

Fixes #9107

* Add client warning notification when MQTT broker is unreachable

Per maintainer feedback: instead of silently saving when the broker
can't be reached, send a WARNING notification to the client saying
"MQTT settings saved, but could not reach the MQTT server."

Settings still always persist regardless of connectivity — the core
fix from the previous commit is preserved. The notification is purely
advisory so users know to double-check their server address and
credentials if the connection test fails.

When the network is not available at all, the connectivity check is
skipped entirely with a log message.

* Address Copilot review feedback

- Fix warning message wording: "Settings will be saved" instead of
  "Settings saved" (notification fires before AdminModule persists)
- Add null check on clientNotificationPool.allocZeroed() to prevent
  crash if pool is exhausted (matches AdminModule::sendWarning pattern)
- Fix test comments to accurately describe conditional connectivity
  check behavior and IS_RUNNING_TESTS compile-out

* Remove connectivity check from isValidConfig entirely

Reverts the advisory connectivity check added in the previous commit.
While the intent was to warn users about unreachable brokers,
connectPubSub() mutates the isConnected state of the running MQTT
module and performs synchronous network operations that can block
the config-save path.

The cleanest approach: isValidConfig() validates config correctness
only (TLS support, default server port). The MQTT reconnect loop
handles connectivity after settings are persisted and the device
reboots. If the broker is unreachable, the user will see it in the
MQTT connection status — no special notification needed.

This returns to the simpler design from the first commit, which was
tested on hardware and confirmed working.

* Use lightweight TCP check instead of connectPubSub for validation

Per maintainer feedback: users need connectivity feedback, but
connectPubSub() mutates the module's isConnected state.

This uses a standalone MQTTClient TCP connection test that:
- Checks if the server IP/port is reachable
- Sends a WARNING notification if unreachable
- Does NOT establish an MQTT session or mutate any module state
- Does NOT block saving — isValidConfig always returns true

The TCP test client is created locally, used, and destroyed within
the function scope. No side effects on the running MQTT module.

1fe9a41fb9 Fix for preserving pki_encrypted and public_key when relaying UDP multicast packets to radio. (#9916)
* Fix for preserving pki_encrypted and public_key when relaying UDP multicast packets to radio.

PKI DMs sent over UDP multicast had their pki_encrypted flag and public_key fields explicitly cleared before being forwarded to the LoRa radio. This caused the receiving node to treat the packet as a channel-encrypted message it couldn't decrypt, silently dropping it.

The MQTT ingress path correctly preserves these fields. The UDP multicast ingress path should behave the same way.

* Zeroize MeshPacket before decoding

Zeroize MeshPacket before decoding to prevent data leakage.

2aefd386b6 Fix RAK4631 Ethernet gateway API connection loss after W5100S brownout (#9754)
* Fix RAK4631 Ethernet gateway API connection loss after W5100S brownout

PoE power instability can brownout the W5100S while the nRF52 MCU keeps
running, causing all chip registers (MAC, IP, sockets) to revert to
defaults. The firmware had no mechanism to detect or recover from this.

Changes:
- Detect W5100S chip reset by periodically verifying MAC address register
  in reconnectETH(); on mismatch, perform full hardware reset and
  re-initialize Ethernet interface and services
- Add deInitApiServer() for clean API server teardown during recovery
- Add ~APIServerPort destructor to prevent memory leaks
- Switch nRF52 from EthernetServer::available() to accept() to prevent
  the same connected client from being repeatedly re-reported
- Add proactive dead-connection cleanup in APIServerPort::runOnce()
- Add 15-minute TCP idle timeout to close half-open connections that
  consume limited W5100S hardware sockets

Fixes meshtastic/firmware#6970

Made-with: Cursor

* Log actual elapsed idle time instead of constant timeout value

Address Copilot review comment: log millis() - lastContactMsec to show
the real time since last client activity, rather than always logging the
TCP_IDLE_TIMEOUT_MS constant.

Made-with: Cursor

* Update src/mesh/api/ServerAPI.h

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Stop UDP multicast handler during W5100S brownout recovery

After a W5100S chip brownout, the udpHandler isRunning flag stays
true while the underlying socket is dead. Without calling stop(),
the subsequent start() no-ops and multicast is silently broken
after recovery.

Made-with: Cursor

* Address Copilot review: recovery flags and timeout constant

Move ethStartupComplete and ntp_renew reset to immediately after
service teardown, before Ethernet.begin(). Previously, if DHCP
failed the early return left ethStartupComplete=true, preventing
service re-initialization on subsequent retries.

Replace #define TCP_IDLE_TIMEOUT_MS with static constexpr uint32_t
for type safety and better C++ practice.

86dad90573 Fix nRF52 AsyncUDP multicast TX/RX race condition causing garbled packets (#9765)
socketSendUDP() calls yield() while waiting for SEND_OK, allowing the
cooperative scheduler to run AsyncUDP::runOnce(). When runOnce() calls
parsePacket() on the same socket during an active send, the multicast
loopback packet arriving from the switch produces a garbled 8-byte RX
header (wrong source IP, wrong payload length), leading to protobuf
decode errors in UdpMulticastHandler.

Add a volatile isSending flag that writeTo() sets around endPacket()
(the only yield point). runOnce() checks this flag and skips
parsePacket() while a send is in progress. Loopback packets stay
buffered in the W5100S RX buffer and are read cleanly on the next
poll cycle.

Also propagate writeTo() return value in UdpMulticastHandler::onSend()
instead of unconditionally returning true.

cb28c38828 fix(t1000e): reclassify P0.04 as sensor power enable GPIO (#9826)
P0.04 is a digital power-enable pin for the NTC/LUX sensors, not an ADC
input. The old code was calling analogRead() on a floating GPIO that
happened to read ~mid-rail, coincidentally producing reasonable
temperature values.

- Rename T1000X_VCC_PIN to T1000X_SENSOR_EN_PIN and drive it HIGH in
initVariant() for both T1000-E and T1000-S variants
- Read BATTERY_PIN (with ADC_MULTIPLIER) instead, clamped to the 3.0V
LDO output (NTC_REF_VCC) for the NTC resistance calculation
