Hi, I’m using last firmware / modem with a RUTM50.
Configuration is as follow:

  • Firmware version RUTM_R_00.07.12.1

  • Firmware build date 2025-01-27 08:18:44

  • Internal modem firmware version RG520NNADBR03A03M8G_01.001.01.001

GPS Connected and enabled
no dpo
no galileo
no glonass
no Beidou

No sim inserted
uplink wired to wan network with internet access

My issue is that GPS does not fix (in map) and also does not update in gpsctl all values returned are 0.

gpsctl -dtpse returns :
0
0
0

Hello,

Could you please confirm if the GPS antenna is properly attached to the router? It is very important to connect the GPS antenna to the device and place it outside (rather than inside a building). Otherwise, the device is unlikely to obtain a GPS fix.

Best regards,
