I get the same error even without turning off the Device. Transmission of bytes 
works a few times but then fails with this error :-(

Android 2.3

My work around was to check for a confirmation reply from my bluetooth device 
and if I did not receive a confirmation within a timeout period to attempt to 
automatically reconnect.


input_buffer = []
time_out = time.time() + .5
while('\n' not in input_buffer):
    while(droid.bluetoothReadReady().result == False):
        if(time.time() > time_out):
            raise Exception
    input_buffer.append(droid.bluetoothRead(1).result)


This code has a half second timeout.  It reads in data one character at a time, 
and if it doesn't receive a newline it assumes something went wrong and throws 
an exception.  My exception handler then would automatically reconnect, and try 
sending data again.

This may not work in your case if disconnections are extremely common, or if 
the device does not send a consistent acknowledgement of data received.
