Hello,
I found a strange correlation, and cant find any documentation on it, about how le\_gnss relate to radio.
I see that if i send a cm radio off command, or if the network got lost (no registration), GNSS handler (le\_gnss\_AddPositionHandler(…)) stop producing location and in logread i receive this error:
posDaemon[1940]/le\_pa\_gnss T=unknown | pa\_gnss\_qmi.c PositionHandler() 1509 | Bad position indication.
if I check with gnss get status it’s ACTIVE. the only way i have in code to receive positions again is to issue a gnss stop and a gnss start on command line.
Am 'i missing something? I just want t contiinue to receive position changes even when radio is off or when there is no network or it’s unreachable. How can I solve?
I can naturally continue to check if network is ok and in that case issue the stop&start command… but i dont like this solution at all.
Regards,
Gianmaria

Are you using agps?
Suggest you trying with AT!gpsfix with standalone mode

I suspected it was something like this. Thanks jyijyi, can i set in stand alone mode via code? I’m not so practical with sending at command directly.

using:
le\_gnss\_GetSuplAssistedMode(LE\_GNSS\_STANDALONE\_MODE);
doesn’t work.
cm radio off stops also the gnss service, or at least it’s active but no positions were produced.
I will try the AT way and let you know.
regards,
Gian

No way also sending AT!GPSFIX=1,255,10 over AT, with microcom on /dev/ttyAT.
if you send radio off and radio on, the gnss stop producing positions samples.

Does at!gpsfix work when radio on but network lost?

It seems that on network lost it’s ok. I will make a lot of tests on filed and will update this thread if i find more details.
Thanks for support.
