Summary of changes
If the user sketch starts and stops BLE several time, after the first time, the BLE stack advertises the wrong BLE mac address ( "AA:AA:AA:AA:AA:AA" ). This is caused because the BLE.end() function of ArduinoBLE doesn't turn off correctly the BLE mbed-os library.
Here a cketch for reproducing the bug.
Here the fix on ArduinoBLE
This PR is needed for solving the problem since that after the second wake up the radio chip is not reset and sends an erroneous HCI response that is not related to the Reset request performed by the BLE stack during the init phase. With this change this packet will be ignored, instead of hanging the board. This solution works since the radio chip sends as second HCI response the expected reset response.
