Simple UART Echo Program

Awneil - maybe you can guide me

I connect to my device usb, open the correct COM port in DS and send at commands using the console view. AT commands go through fine so I have a good connection.

Now I try to upload the latest firmware… I go to the status box in the target management view and click the little package symbol beside the Firmware heading. I pick the latest package from the drop down list and start upload. The green status bar completes and then I get the error popup saying “No target detected”.

If I use at+wdwl in DS or any other terminal program I get error response +CME ERROR: 3 which stands for operation not supported.

I am using the Xact Technologies dev board utilizing the WMP100. Xact has their own dwl loader program but I am waiting on it getting updated… Based on what I have described do you think I missing a step in the upload process or is it just that my pcb won’t accept software from DS?

I am sorry I know this is pretty vague
