It would really help if you provided a screenshot your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.

not working. it’s still the same
Please use event Screen.Initialize and not Menu Initialize
Also in the PermissionGranted event after BluetoothScan has been granted obviously you have to ask for BluetoothConnect and not again for BluetoothScan permission

done. but it’s still the same. 
Don’t you think, it probably would be a good idea to provide a screenshot of your updated blocks? How could anyone help without anything?
