New Photon just out of the box.
Whent smoothly trough the particle setup on my iPad.
Device is registred under my account and I can flash SW to it with success, but it will no publish anything.
Can you make sure the code is actually flashed to the device by adding some blinking LED code to it? You can use the on-board LED for a quick test. Alternatively, Serial output is always nice.
OK, seems that it has started to work as it should. Starts to publish data directly after I flash it now. Have not seen this type of behaviour before. Since I cant reproduce this error then we can close this problem.
