Hi - there's a little bit of misinformation going on. We sent a beta test firmware out to a UK tester to verify it can do higher altitude. However, -no- GPS modules we sell have that firmware on it. We had requested from the factory that our next shipment come with the newer higher-altitude firmware but that shipment hasnt
arrived yet. The only GPS with the new firmware is the one the beta tester received. Once we do get the next delivery, all the GPS modules we make will come with the new firmware. However, that is 2 or 3 weeks away at best.
It seems like that beta tester went ahead and wrote up about our test without alerting us, causing much confusion because he had the single test module and there is no way to upgrade current burned firmware with the new higher-alt firmware
you can email support@adafruit to get a refund for your GPS but please alert that website that we are not selling that firmware (yet) and to please not get people's hopes up until we do
We will post on the blog when we get the new firmware in!
