Im flying a raspberry Pi thats connected to a pixhawk. The raspberry is mostly used as camera , it has one (and soon several CSI) camera module('s) attached to it. Right now triggering is done by reading a GPIO port thats connected to a pixhawk relay.
Now I would like to add GPS and sensor data (angles) to the exif tags. On the raspberry I installed mavproxy and dronekit, and while they work, but there seems to be no simple way to get an external program to obtain any data from them. I thought this would be about the most basic use of a mavlink proxy or API, but I guess not.
Im at the point where Im considering branching the GPS wires to the Pi and possibly even add IMU sensors to the rapsberry because I just cant seem to interface with mavlink through anything other than a CLI or modules running inside maxproxy.
Any help would be greatly appreciated.
Dealing with a similar issue - wondering if could share however you eventually got at the sensor data?
