- Tue Apr 12, 2016 3:15 pm #45383 It started to throw some exceptions at me yesterday. So I flashed the firmware today as described here: http://www.allaboutcircuits.com/project ... fi-module/

That worked well (except the Putty part, that won't output the AT command at all).

Than I flashed this small sketch with the Arduino IDE:

Code: Select allvoid setup() {
  Serial.begin(115200);
}

void loop() {
}

Running this sketch, I constantly seeing exceptions like this in the serial console:

Code: Select allException (28):
epc1=0x402015bf epc2=0x00000000 epc3=0x00000000 excvaddr=0x0000001c depc=0x1082b6f6

Did I damage the boar somehow? Is there something else wrong? Should I provide more power? (running it from USB currently with a LD1117V33 between)

thanks and greetings,
