This looks particularly useless:

Export an aia file for your project, and upload it here.

You are not showing us the whole story.

P.S. Also upload the .ino sketch file, if there is one.

ask for permissions correctly, see here

Bluetooth liste of devices deosn't work anymore

To check it out, here are two AIAs. BTclient_test1.aia (7.5 KB) BTclient_test2.aia (7.5 KB) BTclient_test1.aia uses your blocks and doesn't work. BTclient_test2.aia uses my blocks as I always posted them. This works. So build the APKs and check it on Android 12+... And this version works with Companion & APK: [grafik] The extension GetASD can be found here

also the Connect method returns true or false... so usually you would do this

So I doing a project is a smart glasses with translator and the compounds the Arduino nano and 0.96 oled display,HC-05.So im getting an a error 507 i nead a help to solve this error i think the problem on his blocks can help me?!

I'm guessing that your blocks were gotten from an Artificial Intelligence output.
Am I right?

Here they are, for all to see:

I did a Cleanup Blocks, to arrange them vertically, to let us take the grand tour scrolling down.

I had to add this to fix the 30 red errors in the translation section:

Your blocks had no global variables.

Read the chapter on variables in the free online book at

This block has several errors:

• It does not check if the BT is connected (direct cause of 507 error) before sending
• It ignores the local variable supplying the translation, instead imagining a non-existent compiler that turns peudo code into code.

This is another example of your variable phobia:

It also carelessly sends text without checking if still connected.

Do not start more threads.

Also, post the sketch here, in this thread.

on your phone,

• goto settings
• search for your app
• in App Info for your app select Permissions
• change Nearby Devices from Not Allowed to Allowed
• Done

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.
