Hello!
In November, I made an app that connects to a BT device. Recently, I wanted to make a small change and noticed that in the new application, the list of BT devices is empty.
As I browsed through the topics, I saw that there had been changes.
However, my poor knowledge of English and the APP Inventor environment do not make my task easier.
Can anyone give me a hint or show me how to change the blocks below so that I have paired BT devices available again?
"połącz" is "connect" button
(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
(Thanks to @Patryk for correction to grant order)
Special note for Xiaomi devices:
Where I can find "AskForPermission"?
I don't see it in "Procedures" or in the "Bluetooth_Client1".
Ask for permission is a Screen 1 block.
These samples can be dragged in the browser, to save on retyping.
P.S. These blocks can be dragged directly into your Blocks Editor workspace.
See A way to group projects by theme - #10 by ABG
for a demo.
Thank you for the advice. Unfortunately, drag&drop doesn't work for me. 
OK. So I have these blocks
But when I run the app I get an error notification:
Bad arguments to >=
The operation >= cannot accept the arguments:, ["API Level not found"], [31]
What do you get back from Screen1.PlatformVersion?
Apparently, it might not be in the apiLevel list.
How I can check what I get?
Assign it into a Label.Text temporarily, or use the Companion's Do It facility.
