Ultimate GPS timestamp wrong with fix loss

Post by adi_b »

Been trying to get the ultimate GPS featherwing working with the STM32F405 featherwing. No issues getting the GPS data out when there's a fix. I have the back up battery installed.

While there is a fix, I get valid location, time and other navigation information. However, when I lose the fix, the timestamp is stuck on the last good time reading from the fix.

Has anyone encountered this? All documentation says that I should be able to continue to read the correct time by querying the time as shown in the example, but that's clearly not working for me...

It almost looks like after the fix is lost (simulated by disconnecting antenna), there's about 4-6 seconds of good time stamps, before it gets stuck.
