Downloading .dwl

Hello,

I have a problem with my code, First I download the .dwl, and the code runs ok, but I can’t switch to development mode, so I don’t know how to download more codes because none AT comand works. So how can I donwloand .dwl when the firmware is working and none At command is attended???

Thank you,

Anna.

Does your application use FCM to switch the UART out of AT Command mode :question:

yes.
