Adding the “uses-feature” to the manifest in the project folder didn’t solve the problem. I still get the same error message, therefore I am unable to get the demo to give me a serial port list. However, I have looked in the tablet’s settings and can see that I have previously paired the Bluetooth shield for use with another app. Just to see what would happen, I unpaired it and tried to re-pair it. Now it does not show the shield as being available for pairing and I am unsure why. For now it appears that recognition of the port is the problem and will need more trouble-shooting. I appreciate your help. Will provide follow-up if I ever get it working.
