Based on the current hardware form of the indicator, GPS data needs to be collected through the RP2040 serial port and then forwarded to ESP32 (the core running meshtastic). We have set the serial port as a serial port connected by two chips and temporarily use serial port transparent transmission to support GPS data. The GPS uses Air530Z,Add another layer of suitable data protocol in the subsequent upgrade to enable RP2040 to support more sensors. The firmware running on RP2040 can refer to the example code provided by this repository.
