TinyGPS Fix Quality has this information: 0 - fix not available, 1 - GPS fix, 2 - Differential GPS fix (values above 2 are 2.3 features) 3 = PPS fix 4 = Real Time Kinematic 5 = Float RTK 6 = estimated (dead reckoning) 7 = Manual input mode 8 = Simulation mode the previous Airoha code would allow quality >0 , which includes estimated positions. These wouldn't be passed through to the mesh due to other checks, but would affect the Airoha GPS_FIX_HOLD_TIME calculations. Changes the calculation to 1 >= quality <=5 .
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.
