Android Question Serial/Bluetooth tutorial doesn't compile

[HansDieter]

I installed the serial tutorial, bluetooth.zip in https://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768/#content.I can't compile it.

What's wrong?

You are using the B4A SDK Manager?
What is the path to the bat file in the SDK Manager?
What is the pth you configured in the IDE (Tools Configure Paths) to the Android.jar?
