Unable to make Cellular Monitor v2.4.0 work.

[JackW]

I am able to open up the Cellular Monitor and successrully select the device an get a connection.  However the option to ' Open a Serial Terminal' is greyed out, and so not available.

Hello Jack,

What device are you using? Is it a DK?

If you hover over the grayed out option, does it say anything about the reason why?

Regards,

Elfving

 Hi Elfving,

Hovering the mouse over the two greyed out buttons doesn't show anything.

We're connecting to our own nRF 9160 based hardware with our own custom firmware.  The FW includes Asset Tracker II FW.  We've also included the necessary AT Host FW.  We're currenlty running modem FW 1.3.3 on the device.  Also we're using an nRF 52840 and a connectivity bridge to make the USB connection.

I can provide more details on request, but we appear to be making a successful connection from our desktop machine to the device.  Here's the log file from the Cellular Monitor:

Hope that helps.

Ah did you do this using custom installation of JLink? We usually recommend going with the one that comes with nRF Command line tools as it is what has been tested.

Could you run nrfjprog -i in the command line and give me the output?

Elfving

OK Elfving, I need a little more help here.  I downloaded and installed the nRF Command Line tools into my Program Files/Nordic folder on my Windows 11 desktop machine.  I then fired up Powershell, set the working directory to C:\Program Files\Nordic Semiconductor\nrf-command-line-tools> and then entered the nrfjprog -i into the command line.  The result is nothing.  Just back to a blank command line prompt.

So, don't know if I'm doing this correctly or not.

[Elfving]

Ah mistake, that went a bit to quick. nrfjprog -i lets you know about the devices connected. I was however wondering about the version.

Run: nrfjprog -v

Regards,

Elfving

[JackW]

OK, here's the command and response:

PS C:\Users\jackw> nrfjprog -v
nrfjprog version: 10.24.2 external
JLinkARM.dll version: 7.96i

Jack
