GPS Recorder - track filename ? and potential issue

Hi,

Thanks for that testing! That's very surprising - the UBX-CFG-CFG command you're using sure looks like it'd be doing the correct thing.

1. Maybe leave it for now - if it turns out you don't have any success in a week or two then we can figure out what we're going to do.

2. Ok, sounds good - but how about just responding to the Bangle.on('GPS' event? That'd work on all devices. Also bear in mind that I've now renamed getGPSPower to isGPSOn because it turns out I already has isLCDOn and wanted to keep everything looking the same.
