I am new to Android programming. Trying Basic4Android hoping it will be easier to use than Eclipse, Java, Xml.... So far it does seem much easier. I hope to convince my company to purchase it.
I'm having a problem running this Bluetooth sample app.

It will not connect to my android phone. I am running the app on a Samsung tablet connected to the PC. I put my phone in discovery mode, click Search for devices, select the phone from the list, it tries to connect then I get this error message
java.io.IOException: read failed, socket might closed or timeout, read ret: -1
I have restarted the tablet, phone and PC several times. Always get the same error.
