Why does an error pop up when connecting a bluetooth device in an application created through App Inventor?

Question

Arduino

I decided to try my hand at App Inventor. Created an application that helps to connect the phone with the HC-06 bluetooth module and send messages to the microcontroller. When trying to connect the phone to the HC-06, an error pops up (see screenshot). At first I sinned on root rights, but, as it turned out, even with root access, the error does not disappear anywhere. If you have any questions to clarify the information, then write)

Answer 1

The problem was resolved by switching to a new version - App Inventor 2. There are no such problems

Answer 2

Question from the series "I'm lazy to read." On the message in Russian in black it says that the application does not specify Permission on BLUETOOTH_ADMIN
