Hello other experienced users,
I've been using the UNO and have successfully uploaded sketches which have worked fine. I got a Nano and thought there was something wrong with it since nothing would upload even after trying different USB cable and trying all available comm's switching the board type from UNO to Nano. Nothing works other then the program shipped in the NANO - the red led is on and the d13 on-board LED is blinking since they seem to have pre-loaded blink at the factory. I do get the TX & RX LED's blinking when I first connect to my PC and if I send a command to the board I see the RX give a quick blink but it seems that nothing ever comes back to my PC. I'm sad and angry and frustrated and do not know where else to turn. Can someone please help!!!
