Hi,

Yes, I have tried it, and for me, it works as expected.

I start with sending AT+CEREG=5, and AT+CFUN=1 to conenct to the network.

When I get the +CEREG=5 (or 1) notification indicating I am connected to the LTE network, I issue AT#XNRFCLOUD=1 to connect to nRF Cloud.

When I get the notification saying I am connected to nRF Cloud, I use AT#XAGPS=1,1 to start the GPS, which will trigger a request for AGPS data.

After the device has received the data and injected it into the modem, I use AT+CFUN=20 to disable LTE. This will also force a disconnection with nRF Cloud, as I no longer am connected to the network. However, the GPS will keep running.

What error did you get, and what do you mean that "agps doesn't work"?

Adding logs showing the errors would also be helpful understanding what is going on.

Best regards,

Didrik
