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

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.

You must enable app permission to use bluetooth in your phone setting. Setting - Apps - Permission manager - Nearby devices, and allow your app. I use LG V50.
It maybe difference with others brand smartphone.
