Hello
I am trying to connect the nRF9160 -DK board to nRFCloud using CoAP protocol. I have written an application for this case. I tested my application with two different SIM Cards.
One of the sim cards supports LTE connection and the other one supports only NB-IoT. Using the LTE SIM card I can successfully connect, but using the other SIM Card that only supports NB-IoT can not connect to nRFCloud using CoAP.
On the following screen shot is the LOGS of the system using the NB-IoT connection.
The Error occurs when I call the nrf_cloud_coap_connect("1.2.3"); function in my code.
In case I use the LTE connection, using the first sim card, I have a successful connection to the nRFCloud.
To test if there is something missing in my code, required for NB-IoT connections I also used the nrf_cloud_multi_service example from nordic, using the overlay_coap.conf to enable the CoAP protocol.
In this case I have the same results as using my code, described above. With LTE connection I can connect to nRFCloud, but with NB-IoT connection it does not connect.
In the following picture is the LOGS from the nrf_cloud_multi_service example using NB-IoT connection.
As far as I know the CoAP can work using NB-IoT connection. Is there any other requirements to connect to nRFCloud using CoAP via a NB-IoT connection? What are the possible reasons for this matter?
Thank you in advance
