I am using my N+2 to receive serial commands from a device and report back an encoder position. It works fine when the Netduino is powered by my computer, even when Visual Studio is not running, but it won't send a complete reply when powered externally. I am sending the position info with a start and end character, but the device only receives the first 3 bytes when powered externally.
Anybody have any thoughts on how to fix this?
