Android Question BTPrint Error

[juanM1]

Hello.
I have been using BTPrint for several years, and now with a Galaxy Tab A8 running Android 11, I get the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'java.iutputStream android.bluetooth.BluetoothSocket.getOutputStream()' on a null object reference

Sub BTPrinter_Connected(Connected As Boolean)
     BTConnected = Connected[]

     BTPrinter.Initialize(BTConnection.OutputStream) [B]Here it gives the error.[/B]
     PCL3.Initialize(BTConnection.OutputStream)

     CallSub(BTNotify, BTNotifyRoutine)
End Sub

On an Amazon Prime 10, and it gives the same error.

Thank you and greetings.
