Hi,
Please check that the COM port is not reserved by another application like terminal emulator.

Hi,
so i download nRF connect for desktop and JLink_Windows_V856a_x86_64, install USB driver, open quick start , choose at command and start programming,and verify
Do i miss any step?

Leo
Hi Juha,
I found out that I can verify successfully after programming Asset Tracking and Shell Command Line Interface, but I failed to verify after programming AT Commands, how can I fix that?
I just want to use at+cfun=4 and at+cfun=1 to control the model to connect to the network emulator, what should I do now?
Regards
Leo
