nRF9161 DevAcademy Course

[SteveHx]

I am attempting to work thru the tutorial exactly per the instructions, and I'm stuck in Lesson 1 at

         6. Wait for the device to connect to nRF Cloud.

The Cellular Monitor shows the board connected to AT&T with SNR at 10dB, which ought to be plenty for anything it needs to do. The board is properly configured into nRFCloud.

What am I missing?

Ideally I would like a sequence of commands that sends data that I can see displayed on nRF Cloud, and a second sequence that sends a text message to my phone. Is it really too much to ask for a simple example?

No so hard when you specify what you want to do. I just tried with SLM example commands, below is the related pages I followed and logs generated.

nRF Cloud following example:  https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.6.0/nrf/applications/serial_lte_modem/doc/NRFCLOUD_AT_commands.html#example

Pay attention that you need to provision the device to nRF Cloud with UUID, this is mentioned in "Note" above page.

SMS following:  developer.nordicsemi.com/.../SMS_AT_commands.html

"AT+CPSMS=0" and "AT+CEDRXS=0" are used to turn off PSM and eDRX respectively, so the power saving feature will not delay SMS receiving.

Please pay attention that no all Cellular IoT SIM card will support SMS, you need to check with your operator if they have enabled this feature.

The second example (SMS msg) fails, presumably because the iBasis SIM provided with the devkit does not support SMS. The first example (nRF Cloud) fails at the command AT#XNRFCLOUD=1, with the reply ERROR. Not a particularly helpful diagnostic.

Could I ask for a short session via Zoom etc., so you can look electronically over my shoulder and explain where I'm going off the rails? I am available for the next hour, then any time after 1330 EDT (1730EDT) today.
