Android JDY-016 bluetooth error 507

[Pieter_J_van_Horssen]

My setup is like this:
Lafvin 2wd robot car v2 with ARDUINO BOARD.
Android mobile phone with android version 14
The bluetooth module is a JDY-016
I have a button connected to beforepicker and the phone bluetooth is connected to the JDY-016 because the red light is steady.
When I click the Connect button on my phone I get the correct bluetooth list with also JDY-016 in it. When I select the JDY-016 I get the error507 and no connection of course.

You forgot to ask for Bluetooth connect permission

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

Thanks very much for your help. I have implemented your solution but my app still get error 507 and it comes back with "Trying to connect" and than the complete list of BT devices online.

Forgot to tell you that with your BTclient_test2.aia app I can select the JDY-16 but than nothing further happens. the JDY-16 is connected to my phone because its red light is steady.

@Pieter_J_van_Horssen

. I have implemented your solution

It would really help if you provided a screenshot of 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.
