Hello,

I have tried running both heartbeatRed and timerLed but both produce no results, there is no flashing LED or output in “logread -f”. I have also tried using the AT command “AT+WIOCFG?” and I see that GPIO 34 is set to 16 (I have also reset it again just in case). At this point I can’t think of any other way to get the LED to blink. Any suggestions or help would be very much appreciated.

Thanks  
Kas
