Spent some hours today working on getting the Arduino HC-05 running, and then testing it. I was able to connect the HC-05 through the Arduino to send serial hello world messages to my computer. Using the computer I am able to see the messages with the RFCOMM server through the command line.
I am having a hard time with the QTBluetooth API though, still debugging because the bluetooth socket does not connect, it gets stuck in the connecting status???
