No GPS Signal, How to Diagnose

Post by Pezmc »

I'm using a ONE+ model B with a SIM and it never seems to be able to geolocate.

I'm using telelogger v5, with additional logging modification and this config.

I'm sat outside with a clear view of the sky, powering the B using a laptop (over USB). Even if I leave the unit awake for ~5 minutes (by moving it so standby doesn't kick in), FreematicsESP32.gpsGetData just never seems to return any data.

What should I be doing next to diagnose? Is there anything I'm missing?

Full output up to a first sleep, looks as follows:

Besides my email to you, another suggestion is try powering the device from OBD. Some laptop's USB ports are not able to supply enough current surge.
