P.S. These blocks can be dragged directly into your Blocks Editor workspace.

same problem with me

(Canned Response ABG - Bluetooth non-BLE SCAN Permission Blocks)

These blocks can be dragged into your Blocks Editor to request permission(s) for Bluetooth non-BLE scanning and connecting. All three parts are needed.

You also will need to pull in TinyDB into your project.




Thanks to @Anke for the original code.
My changes include

  • use of the Screen1 permission blocks to avoid the possibility of a typo
  • using a TinyDB tag particular to BT permissions and only for BT permissions.
