I am working with the Android Bluetooth Chat sample application. I am trying to read serial data from the Android device in Windows 7.

I have been able to pair the Android device to the Bluetooth adapter on my laptop. I replaced the UUID in the sample application with the following per some other discussions:

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

When I run the Android application I am able to connect to the laptop. In the “Hardware” properties of my Android device there is a “Device Function” entry called “Standards Serial over Bluetooth link (COM10)”. When I attempt to connect CoolTerm to COM10 I receive “error 1168” (there is no additional description for the error).

Am I misunderstanding something about the process of sending serial data via Bluetooth to a Windows com port?

    Be sure that you are selecting the correct COM. In my last Android application that required SPP (Serial Port Profile) Bluetooth communication, when Windows 7 paired I had several COM’s open up.

    If COM10 is not working, verify that it is the “incoming” COM (or maybe it’s outgoing, I can’t remember b/c it’s been a few months).
