Checking all the sensors

[tve]

I have a Pixracer and a Ublox Neo M8N GPS/Compass, this means there should be one GPS, two compasses, two accelerometers, two gyros, and one barometer in the system. QGC only shows one status per sensor type, how can I check that all sensors are recognized and working, and is there a way to see the relative weights given to each one in the EKF? I’m particularly interested in the compass given that I have some choice about how to place the gps/compass module to possibly improve the sensing. As it stands, I don’t even have confirmation that I wired it up correctly…
