CAN GPS Blue LED

#1

On my Pixhawk 2.1 with Here 2 GPS. On mission planner I am showing a lock and position is correct but HDOP is 0 and GPS has a flashing blue light

GPS Hardware Version 2.1 software Version 1.3.1971872918

Arducopter 3.7-dev

Any thoughts

This is normal on CAN.

There is no HDOP message on the can device.

HDOP is not an great way of checking gps. The EKF uses the velocity innovation to determine quality

#3

Is there any way to tell visually if you have a good lock eg Green led like the serial version

#4

EKF will not pass checks till a good lock is achieved

#5

Thanks for clarifying might be good to have in a future release
