Grove and other Bosch modules strap SDO high, so the 0x76-only table
never initialized them. Add an alternate-address entry per Bosch sensor;
the bus scan still gates every probe, and all four drivers verify a chip
ID before claiming an address.
Each sensor type has a single static driver instance, so skip an entry
whose query is already active: the alternate address is a fallback, not
a second device.
Several table entries share an address and not every driver verifies a
chip ID: INA226::begin() only checks that the address ACKs, so an SHT4x
at 0x44 was also registered as an INA226 and reported junk current on a
second channel. Mark the address consumed once a driver initializes it
so later entries cannot re-claim the same device.
RadioLibWrapper::setTxPower() called setOutputPower() and nothing else. On
LR2021 that writes the PA config and TxParams, which are standby-only commands,
and it never re-arms the receiver.
This only affects LR2021 boards. recvRaw() has:
#if defined(USE_LR2021)
state = STATE_RX; // LR2021 stays in Rx after readData
#else
state = STATE_IDLE; // need another startReceive()
#endif
so on SX126x the next recvRaw() re-arms Rx anyway and the write is harmless,
while on LR2021 startReceive() is never called again on its own. A 'set tx'
issued while the radio was listening could therefore stop reception until the
next reboot. Observed a few times on an LR2021 repeater; recovery required a
power cycle.
Dispatcher's stuck-radio check does not catch it: isInRecvMode() reports the
wrapper's own `state` flag rather than the chip's actual mode, so it still
believes the radio is in Rx, and it only raises ERR_EVENT_STARTRX_TIMEOUT
without attempting recovery.
Fix: on LR2021, drop to standby via idle() before writing the PA config and let
checkRecv() re-arm Rx - the same pattern resetAGC() and
applySideDetectorConfig() already use. Other radios are left untouched.
Affects meshtracker_x1 and meshnology_w12 (both USE_LR2021).
Tested on hardware with an LR2021 repeater: six consecutive 'set tx' changes
(15/18/21/14/19/14), after which the radio kept receiving and forwarding
traffic (rawrx/rxpkts increasing, no missed IRQs). Noise-floor sampling also
kept updating, which only happens while state == STATE_RX.
SPI pins that are set to -1 cause OOB reads on NRF52. The unused Serial2 pin definitions were removed to avoid potential issues with the Uart framework.
Setting SPI pins to values that are OOB of the g_ADigitalPinMap[] array causes OOB reads. This variant.h has pin 0 as 0xFF which passes through as NRFX_SPIM_PIN_NOT_USED.
Introduced consistent preferences for external LoRa FEM RX and TX gain settings in NodePrefs. Updated companion MyMesh to apply these settings during initialization and transmission. Added unit tests to verify the round-trip serialization of these new preferences.
