I have this problem occurring sometimes after flashing a new program. The Bluz LED does not light up. Everything gives the indication of a dead board until I reset the firmware. I usually then flash a simple sketch, upgrade the firmware then flash my program again. This is time consuming and cumbersome. Is there a less draconian way of getting the board back when this happens?
I tried a simple press on one of the two buttons on the board and this does “wake up” the board.
Also, System.reset() causes the LED light to disappear. Sometimes, even a power disconnect does not solve the problem. Waiting a little after disconnecting power sometimes works but is not practical in remote installations.
What is potentially causing this behavior? BTW, sometimes I also get 8 flashing red light sequences after an SOS. I did look it up (System tried to enter an invalid state) but not sure what it means?
Thanks in advance.
