Reminder: Update your Dual firmware

Post by nanotech » Mon May 27, 2019 10:39 pm

The GPS epoch rolled over on April 6th. Older Dual firmware versions (mine was 1.4.1 for a 160) don't seem to support the epoch roll-over. Could not get a lock no matter how many times it was reset. Great connection, no data. Waste of a track day trying to get it to work, fell back to phone GPS and plotted buying a Vbox.

I've since updated the firmware (using the horrible Dual Android app) to 2.5.4. Cold-started the GPS after update, and back in business. Locks to both GPS and GLONASS, works pretty well driving around town.

(Not sure why it didn't fall back to GLONASS but ??? code is fun.)
