Mini Ultra pro sleeps forever.

Hi all,

I am testing now a V.2 card, and accidentaly I didn´t change the pin mapping in the sketch, now the card is not responding, the green led is turning on but Arduino IDE is not recognizing it anymore. The sketch loaded is:
Have you seen a similar problem?

I normally load this configuration and it works properly:

// Pin mapping
const lmic_pinmap lmic_pins = {
  .nss = 5,
  .rxtx = LMIC_UNUSED_PIN,
  .rst = 3,
  .dio = {2, 6, LMIC_UNUSED_PIN},
};

Thanks a lot for your help.

Try to upload a simple blink sketch to the board to get the board out of this state. You can do this by double pressing the reset button in quick succession after you press the upload button on the Arduino IDE. This works all the time.

Looking at your code, the code uses Serial instead of SerialUSB for debug information. So, unless you are connecting the Serial pins on the board to a USB-Serial converter, you won’t see anything if you connect the Mini Ultra Pro’s USB port to the IDE.
