I have tried to comment out initBT() as well. I've made it lowest possible level with just a main, as Serial.begin and Serial.print and it still does it. I'll take a look at their main function and see what I can deduce from it. It's weird because I've never really had this issue using my own main function before but usually my code runs inside a while loop. I'm thinking therein lies the problem that I'll have to go searching for.
