Hello everyone I am doing a project related to arduino mega + hc-06 bluetooth. I create applications in the mit app inventor. So here's the problem, the phone detects Bluetooth and connects, but it doesn't see it in the ListPicker app. Please tell me what I'm doing wrong.
Thanks for the feedback!
I tried your app and read the article. But it didn't help me. I downloaded the bluetooth app from the play market. Everything works there. But my app doesn't work.
Device name & Android version?
Galaxy A23. Version android 13
Hmm, should work. Did you try my second test aia. If so, post screenshot(s).
I tried it. Through the online AI companion, then your and my app sees bluetooth and works. But if you download it, it doesn't see Bluetooth.
Try this one:
and post a screenshot.
I'll answer later... (I'm not at home)
Ask for permission

The easiest solution, for immediate relief
(from @Barry_Meaker) ...
I had the same issue. The problem is your app does not have permission to see nearby devices. The solution is to give your app permission on your phone (no code changes in your app).
on your phone,
By the way, the very first time you run the app, Android will ask if you want to grant the app this permission. If you say no, or ignore the pop-up, the permission will be set as Denied. Android will not ask again.
A more complex approach, for professional app development:

Special note for Xiaomi devices:
I have an error with bluetooth on android 12, Xiaomi Poco X3 NFC - #20 by Patryk_F
Thank you very much! It worked
I had already posted the same (relevant) links. So what did @Taifuns's last post change that?
