Struggling to get PNT data from the BG95-S5

I am trying to get the BG95-S5 to register with an NTN service. I can now see the service, which is an improvement, but it will not register yet. I understand that NTN services rely on a transmit burst plan, so it is essential to send accurate PNT data along with the registration request. Good so far. The problem I have is that the onboard GNSS service on the BG95-S5 does not report any position data. It is failing to find any GNSS satellites. I have tried the following logic sequence:

  1. AT+CFUN=0
  2. AT+QGPSCFG = “gnssconfig”, 3
  3. AT+QGPSCFG=“nmeafmt”,1
  4. AT+QGPSCFG=“nmeasrc”,1
  5. AT+QGPS=1

I then thought it might be possible to inject PNT data from an external device, but this has not worked either.

Can you suggest either, how to start the GNSS service properly, or, how to inject PNT data from another device, such as the Quectel LC29H.

Thanks

Hi @JohnMu

There is no need to enable GPS manually(AT+QGPS=1 .etc), it will be enabled automatically. or you can inject PNT data by this command.

That’s interesting and completely new information. Can you send me that document please.

Also, can you please send me the sequence to search for, and register to an NTN service.

Thanks

John
