Hey everyone,


So my project simply contains a Netduino Plus Firmware 4.2 and a Bluetooth module. I had some code that was accepting commands from a WP8 app. The Bluetooth would simply receive text from the phone and the code on the Netduino would switch the onboard LED on and off. I added a SainSmart relay for some testing. This is where I ran into a problem.


The Netduino stopped responding to commands. I have the BT module on COM1. In VS 2013 the program will not debug correctly. It exits before I can do anything. The only way to get the Netduino to do anything is right before the program exits I hit the On button on the WP8 app multiple times in a row and then it will turn the LED on. But after that can can't turn it off with the WP8 app. To me it's just really weird. Maybe my BT module is bad or Netduino is Bad? I have tried other COM ports also. Any help would be much appreciated. Thanks!
