Road test A7670 esp 32, filtering GPS readings somehow difficult using H/V/PDOP and distance, a new filter has been setup using speed and distance.
Finally got both modules to work properly, a Haversine routine has been implemented to compute the distance between the GPS measures.
Working on a T-SIM S3 A7670G
Web side of the tracker is now operational for multiple trackers
The GPS of the 7670E is less sensitive then the 7600’s unit, MQTT message being sent based on the distance between measurement has to be adapted.
