Title: Bluno Beetle BLE Bluetooth Connectivity Problems
Post by: mtbhack on Jul 05, 2020, 08:25 pm

I recently purchased two DFRobot Bluno Beetle BLE boards with the intention of shrinkifying a project. To get to grips with the board, I followed the "Bluno Beetle Simple Tutorial" to the letter throughout parts 1 to 3. Everything seemed to go to plan with the serial monitor returning the expected "OK" results in the AT  Command Mode.

However, following this process, the board doesn't show up on any Bluetooth device (laptops, phones etc). Updating the BLE Firmware didn't yield any results. Reading around the forums, it looks like other users are having the same problems without resolution... It seems as though something simple is being missed.

Any advice will be greatly appreciated!
