* test: exercise RadioLib's drivers through a recording HAL, pinned to RadioLib 7.8.0 test_radiolib_drivers drives the RadioLib calls Meshtastic's radio interfaces make against RecordingHal, which logs every SPI transaction and answers with a success status, a few scripted replies (the packet type the LoRa setters check) and, for SX127x, a register file. One set per chip family - SX126x, SX127x, SX128x, LR11x0, LR2021 - each ending in a list of the reply-dependent tests still to write. SX126x and SX128x get the SPI framing their begin() would set. RadioLib is pinned to 7.8.0 to show the failure: the LR2021 DC-DC workaround (jgromes/RadioLib#1864) passes sizeof(uint32_t) as a word count, and under [env:coverage] ASan aborts the LR2021 set with a stack-buffer-overflow in readRegMem32. The other four sets pass. * test: pin RadioLib to the DC-DC word-count fix NomDeTom/radiolib@3509dbc8e (branch lr2021-dcdc-regmem32-len, on RadioLib master after 7.8.0) passes 1 as the word count at the three DC-DC workaround call sites. The overrun is gone and the LR2021 set runs to completion. test_lr2021_dcdc_freq_lf_write_sends_one_word still fails, on a second RadioLib bug: LRxxxx::writeCommon() sends 4 + 4*len bytes whatever the address width, so every LR2021 WriteRegMem32 (24-bit address) carries one uninitialised trailing byte - 10 bytes where 9 are meant. * test: keep RecordingHal reachable across a failed assertion A failed TEST_ASSERT longjmps out of the test, skipping destructors, so each test's local RecordingHal leaked its transaction log. LeakSanitizer then reported it at exit, and under [env:coverage] a plain assertion failure came out as an ERRORED suite (run 36412456860: 26 Tests 1 Failures, then a 384-byte leak from RecordingHal::spiTransfer). One static HAL, reset at the start of each test, stays reachable, so a failure reports as FAILED. * test: run the RadioLib driver suite against develop's RadioLib pin Revert the pin to develop's 510e00cfb (RadioLib 7.7.1). That RadioLib predates the LR2021 DC-DC workaround, so its three tests would only fail on their own premise there. They now register only when LR2021 has the public setRegulatorDCDC() that jgromes/RadioLib#1864 added with the workaround: any RadioLib carrying it runs them, and none is left ignored. Against 7.8.0 the suite shows the DC-DC overrun (ASan, run 36412379592). Against the DC-DC fix (NomDeTom/radiolib@3509dbc8e) it shows a second bug: every LR2021 WriteRegMem32 sends one byte too many, since LRxxxx::writeCommon() still sizes the frame for a 4-byte address after jgromes/RadioLib@e3af85867 made it 3 on the LR2021 (run 36412456860). Neither is reachable at this pin. * test: pin the coding-rate byte the radio interfaces send LR11x0Interface, LR20x0Interface and SX128xInterface all call setCodingRate(cr, cr != 7), so 4/5 goes out with the long interleaver. The modulation tests used the driver default (short), and only counted frames. Pass the flag the firmware passes, and add a test per chip that reads the coding-rate field back from the last modulation-params frame: 5 for 4/5 long, 3 for 4/7 short (RadioLib 7.7.1's encoding). Also correct test_main.cpp: at the 7.7.1 pin the LR2021 DC-DC tests are not registered, so the set does not fail; the 7.8.0 overrun is now stated as conditional on a RadioLib that carries it.
Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
