GPS Recorder: invalid Date of Track

Ok, it sounds like that's probably not your issue then. tracklist is completely blank, which means that the Puck.write command hasn't received any data (but it appears to actually be there when you did Puck.debug = 3).

So about the only thing I can think here is that it's actually timed out waiting for a response. If you paste this into the IDE:

var t = getTime(); for (var n=0;n<36;n++) {
      var f = require("Storage").open(".gpsrc"+n.toString(36),"r");
      var l = f.readLine();
      if (l!==undefined)
        Bluetooth.println(n+","+l.trim());
    } print(getTime()-t)

What number does it give right at the end?
