Hello,
I'm trying to use SLM application on ctcc/nrf9161 hardware (https://github.com/nrfconnect/sdk-zephyr/tree/main/boards/ct/ctcc) however it seems I'm not able to connect to the network.
Setup:
- nRF SDK v2.8.0
- nRF9161 modem firmware 2.0.2 (latest)
For cross testing I used nrf9160dk (unfortunately I don't have 61):
- nRF SDK v2.8.0
- nRF9160 modem firmware 1.3.7
I'm using AT commands to configure chips, flow is the same for both ctcc/nrf9161 and nrf9160dk:
- AT+CEREG=5
- AT+CGDCONT=0,"IP","rh"
- AT+CFUN=1
On nrf9160dk I have no issues with connections, it successfully discovered BTS, get IP etc. (CGATT is 1, there is IP on CGDCONT, PDP context active) and XPING works fine. So I'm sure that APN and my SIM provider is fine.
When it comes to ctcc/nrf9161 unfortunately it never connects to the network, it is stuck at:
+CEREG: 5,2,"DEBC","0423510A",7
And never connects to the internet, even when trying to enforce operator, settings CGATT=1 etc. I did also factory reset on both ctcc and dk and it's all the same. DK works ctcc not. The SLM is not modified, I'm not using any overlays, just "west build -b ctcc/nrf9161/ns" and for dk accordingly.
BR,
Jan
