## Exercise 18: GPS Field QA
|
||
|
|
|
||
|
|
Survey/reconnaissance firmware for LilyGO T-Beam SUPREME.
|
||
|
|
|
||
|
|
This exercise measures GNSS visibility and solution quality, logs results to internal flash using CSV, and provides a minimal serial interface for retrieving the logs in the field.
|
||
|
|
|
||
|
|
Current storage choice:
|
||
|
|
|
||
|
|
- `SPIFFS`
|
||
|
|
|
||
|
|
Current environments:
|
||
|
|
|
||
|
|
- `bob_l76k`
|
||
|
|
- `guy_ublox`
|
||
|
|
|
||
|
|
Primary serial commands:
|
||
|
|
|
||
|
|
- `status`
|
||
|
|
- `summary`
|
||
|
|
- `ls`
|
||
|
|
- `cat <filename>`
|
||
|
|
- `stop`
|
||
|
|
- `erase_logs`
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
- Samples are aggregated once per second.
|
||
|
|
- Records are flushed to flash every 10 seconds.
|
||
|
|
- Satellite snapshot records are written as additional CSV lines when GSV data is available.
|
||
|
|
- The implementation uses common NMEA parsing so it can normalize L76K and MAX-M10S output without adding a new GNSS dependency.
