* fix(radio): never read a RadioLib error code as a packet's time on air
getTimeOnAir() reads the packet type back over SPI on every chip and answers RADIOLIB_ERR_WRONG_MODEM when the chip is no longer in the mode we left it in (a reset or brownout leaves it in FSK). RadioLib returns times as an unsigned microsecond count and its negative int16_t error codes through that same value, so computePacketTime() divided -20 by 1000 and handed 4294967ms up as the time one packet spent on the air.
That single sample is enough to take the node off the air until it is rebooted:
- channelUtilizationPercent() reads 7158% and utilizationTXPercent() 119%,
matching the 7000%+ ChUtil spike and the 120% AirUtil in #11935, so both TX
gates stay shut for the hour it takes that bucket to age out;
- receiveDetected() uses the same figure as its false-header timeout, so
activeReceiveStart is never cleared and canSendImmediately() sees a busy
channel for 72 minutes.
Classify the returned value instead of trusting it. A failed getTimeOnAir() now falls back to calculateTimeOnAir() on the modem parameters we configured - arithmetic with no readback that can fail - and the RX path, which already used calculateTimeOnAir(), is guarded the same way.
Fixes #11935
* style: trunk fmt RadioLibInterface.h
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.
