How to access the nRF9160 modem once it is connected to the iBasic network.

Hi!

Yes, the BSD library can only run in the non-secure application domain, so all applications using BSD Lib will need to be built for the non-secure board (nrf9160dk_nrf9160ns).

You can use +CGDCONT to set the APN and PDP_type. I don't think we have a tutorial available, unfortunately.

I recommend taking a look at all the samples available in NCS to see if any of the applications are similar to your goal.

We have the LTE Sensor Gateway which collects data via BLE and transmits it to nRF Cloud via LTE. The Cloud client sample uses either nRF Cloud or AWS IoT to demonstrate how to use the Cloud API to connect to a cloud service.

We also have the Simple MQTT sample to connect to an MQTT broker and the HTTPS Client sample to connect to an HTTP server over TLS.

Best regards,

Heidi

I was not able to compile for nRF9160 due to BSD library errors, but it built fine for nRF9160ns.

However, each time I enter a wrong command like at+cnum? or ATD*******# causing a +CME: 0, the unit locks up and won't respond to AT. I must re-select the device and then it will accept commands again.

I have not been able to find a resolve for the BSD errors.

Also, is there a tutorial on getting the modem to connect to the iBasis.iot APN? Perhaps I need to write my own application?

I want to use test the LTE modem to act as a conduit to supply sensor data to our data-gathering server. Each of our field units would have an LTE modem to periodically contact a server to send the latest data. (at this point, data could just be simulated)

Hi!

The Asset Tracker application isn't made to transmit AT commands to the modem. For this functionality, you could try either the AT Client sample or the Serial LTE Modem application.
