Hello,
Hope you are doing well.
Could you be more specific in what process you implemented, what steps of the guide you were able to complete and where you left off?
When attempting to flash or debug did you obtain any error logs?
Also, could you please clarify what you mean with "activated BLE"? Were you able to program anything on the board before the steps mentioned on the guide?
If you have more information you can share with us, it would be greatly appreciated.
Best Regards,
Ana Sofia.
