Android Question Bluetooth scan only devices that have the same app

[Almog]

Hello,

I used Erel's example in Android Bluetooth / BluetoothAdmin Tutorial post: https://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768/

Does anybody know if there is a way (in Erel's chat example) to search only for devices that have the same app (Erel's chat example) installed in it, and not all devices nearby that have bluetooth activated.

Thanks in advance.

All nearby discoverable BT devices will be discovered. If there aren't too many devices then you can try to connect to all of them. You can use a unique UDID so it will not connect to other apps that are listening for connections on the default UDID.

Thank you,

You can send please an example of how set a unique UDID in the BluetoothManager class?

Thanks in advance.

Call Serial.Listen2("b4a", "abcd1101-0000-1000-8000-00805F9B34FB") instead of Serial.Listen.

Call Serial.Connect2(Mac, "abcd1101-0000-1000-8000-00805F9B34FB") instead of Serial.Connect.

Call Serial.Connect2(Mac, "abcd1101-0000-1000-8000-00805F9B34FB") instead of Serial.Connect.

Thank you very much .
Is abcd1101-0000-1000-8000-00805F9B34FB is changable? and is "b4a" is unchangeable?

 

[Erel]

Both can be changed.

Both can be changed.

OK, thank you
