Re: Bluetooth connection problem

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

You don't use two COM ports for reading/writing. One port will be for a

connection. Once you have opened a client connection to a remote device you
use the same port for both reading and writing.
