Android Bluetooth java.io.IOException: Connection refused?

Question

I need to connect a KwikBlue-2 Module Development Kit to the Android BluetoothChat example on a Nexus One using SPP. I was able to connect and exchange serial data (once) using tera term after changing the UUID in the BluetoothChat example example to 00001101-0000-1000-8000-00805F9B34FB for SPP devices. Then I power cycled the KwikBlue-2 Module Development Kit to verify that the connection was repeatable but continually get java.io.IOException: Connection refused when I try to connect. Any ideas?

Answer 1

Try unpair/repair and then it may work once again. This seems to be a bug with the core Bluetooth support on Android.
