I cannot run the example either. Someone by the name of Michael Sly replied to me via email and confirmed that i have an SDK version incompatibility with the mfw 2.x.x so we are currently looking into updating to latest SDK and verifying this is the fix.

Hello,

Michal is currently out of office and have assigned your ticket.

The modem FW combination does not look like an issue but I need more information about your setup.

What version of the JLink driver and nrfjprog have you installed? You can find this information by running nrfjprog --version in your command line.

Are you able to run the AT client sample and run e.g. AT+CGSN?

You can use the sample in our precompiled FW package, which you can download from the downloads section of the nRF9161DK product page.

[quote user="Michal_R"]Cellular Monitor doesn't support capturing traces over RTT, only UART, so that may be the main issue.[/quote]

If you do have only access to RTT, you can capture modem traces through RTT by enabling some configurations in your project. Please see Modem trace module. Then run the following in command line: (Make sure to change the path to JLinkRTTLogger.exe)

 nrfjprog --reset && "C:\<PATH TO JLINK>\JLinkRTTLogger.exe" -Device NRF9161_XXCA -If SWD -Speed 5000 C:\Temp\modemtrace_211222.bin

I think you can rename to .mtrace and open with cellular monitor.

Kind regards,
Øyvind

after doing some digging, i found this compatibility matrix

can we confirm that this is why the i cannot talk to the NRF9161?

seems like something might be off, i cannot even send the modem basic commands like

nrf_modem_lib_init(); this returns -1 and

nrf_modem_at_cmd(ret_buf, sizeof(ret_buf), "AT+CGSN"); returns 65536 which is not an error number that is expected to return.

current modem FW i have in the device is mfw_nrf91x1_2.0.1.zip and i am building for the _ns of the nrf9161.

Cellular Monitor doesn't support capturing traces over RTT, only UART, so that may be the main issue.

I would recommending using a USB-UART converted that supports 1 000 000 baud UART if that is a possibility.

Best regards,

Michal

I am consulting the developers about this issue and I'll get back to you.

Best regards,

just the the JLINK SNR number and for chip, it reads as unknown, but i can flash the device with no issues

Hello,

Are you able to detect the device otherwise, for example with the VS Code extension?
