issue with 1v92 on puck - pulsing leds

Odd - had you been using it for anything else beforehand? Was that one that you'd used with a beta firmware? It might be that the beta firmware had caused some corruption of the memory area that's now needed for the Bluetooth stack.

Could you try reinstalling 1v91 on it, and then run the following on it via the left-hand side, and then try re-uploading 1v92?

var f = require("Flash");
for (var i=119;i>=115;i--) {
  print(i);
  f.erasePage(i*4096);
}

thanks! I'd be interested to hear if anyone else has this problem - I had tried upgrading various 1v91 devices before the release, but I guess things changed around with the beta firmwares and that could cause problems.
