LwM2M location assistance

[ibiglari]

Hi,

Happy New Year!

I have been going over LwM2M location assistance documentation, and cannot figure out whether LwM2M library handles the response automatically, or the application needs to handle injecting received AGPS/PGPS data itself (for instance, by calling nrf_modem_gnss_agps_write()) function?

If the library handles this automatically (which appears to be the case, looking at gnss_assist_write_cb() callback in gnss_assistance_obj.c), then documenting the LwM2M object used (33625) would be greatly appreciated, even if it is only the XML object description.

Kind Regards,
Iman

Hi Iman,

1) Yes, the response is handled automatically once you configure the object. gnss_assist_write_cb is used for data injection. You can refer to nRF9160: LwM2M Client — nRF Connect SDK 2.2.0 documentation (nordicsemi.com) to learn how it is used.

2) It is AVSystem actually defined these objects for their platform according to Open Mobile Alliance - LwM2M Registry. You will find the document description from Web GUI when playing with the LwM2M client sample.

Objs initialization process in sdk-nrf/subsys/net/lib/lwm2m_client_utils/lwm2m at 1aa3f9fd37028b9cb16f3351520b9ff80624ba7f · nrfconnect/sdk-nrf (github.com) also give some clue about the recourse inside.

Best regards,

Charlie
