Here4 CAN compass works, but GPS does not. Not sure if power related

Hi guys,

I have a question related to something I’m debugging. If I am using a Here4 for GPS and Compass, and I lose GPS data (evident by failsafe getting triggered and absence of data in logs), should I logically be able to rule out power issues if the compass data is still good and has no issues during the time of the GPS outage? Since they are both on the same device and the same CAN bus?

GPS receiver brown-out voltage is most probably different from compass brown-out voltage.

No, you can not assume that you do not have a power issue, just because the compass datastream does not stop.

Thanks for the reply. Do you know of a good way to test this and try to determine why the GPS data dropout happened?
