Bluetooth Module Issues

07 September 2014 - 12:22 AM

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!

Netduino Plus bricked?

12 July 2014 - 01:54 AM

So I messed something up while flashing my Netduino Plus. Now the Blue LED is always on. I tried erasing the firmware using MFDeploy but it says it can't communicate with the Netduino. I then put the 3.3V to the erase pad below the Digitial Pin 0. I installed SAM-BA but the program gives an error "Error in startup script" and "Error h_handle returned zero". I am starting to think I bricked my board. Just fyi i am using VS2013 on Windows 8.1 with .net micro framework 4.3 and netduino sdk 4.3.1. Thanks!
