An unconfigured slot has an all-zero secret, so it matches null-key group traffic (a sender with an unset PSK). The zero-key MAC validates against the empty slot and the foreign message is delivered as if it belonged to that channel — every node with a free slot is a null-key sink. Skip empty slots.
thinknode_m8: initial support
adds some functionalities to ui_task and epddisplay:
epd display,
- supports screen off, and clear screen
- supports forcing full refresh every N partial refreshes (off by default, configured to 60 for M8)
ui_task
- UI_SHOW_CLOCK flag to display clock on first screen
- rotary button can act like joystick (with regards to Enter key), defaults to old config for existing nodes
- screen off on long press when using rotary button (very handy for the watch)
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.
MAX_CLIENTS is defined in both src/helpers/ClientACL.h and examples/simple_repeater/MyMesh.h. Appears it was centralised in the former header file some time ago. Both are included in some places and, depending on which order they're in, either value can win.
This change drops the duplicate entry from the repeater firmware and bumps the central limit up to 32 (per the original repeater firmware value).
Changes:
- Remove MAX_CLIENTS from repeater MyMesh.h
- Increase MAX_CLIENTS limit in ClientACL.h to 32
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.
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.
CustomLR1110::startReceive() passed RADIOLIB_LR11X0_IRQ_PREAMBLE_DETECTED
(1<<4 = 16) as RadioLib's first argument, which is the RX *timeout*, not an
IRQ mask. At the LR11x0's 30.52us tick that armed the receiver for ~488us, so
it dropped out of RX before any packet could arrive and the node received
nothing at all -- while transmitting normally.
Symptoms on a SenseCAP T1000-E: tx_air_secs rising, rx_air_secs stuck at 0,
recv_errors 0, and the noise floor pinned at the -120 clamp because
getCurrentRSSI() never sampled a live receiver.
Pass RADIOLIB_LR11X0_RX_TIMEOUT_INF (continuous RX), which is what
LR11x0::startReceive() itself uses, keeping the PREAMBLE_DETECTED flag in the
reported IRQ flags as intended.
Introduced in ea5d7c8b ("LR1110: add PREAMBLE_DETECTED to reported irq flags").
Verified on two T1000-E units: with only the repeater fixed it began receiving
(last_rssi -29, SNR 17.0) while the unfixed companion stayed deaf; fixing both
brought up the link in each direction.
