Hi everyone...first post here. I am working with the hello-drone tutorial app on the website and combining it with the functionality of Google's project tango tablet. The app is up and running, connecting to my sitl (px4 and arducopter) and I have been able to integrate the position/orientation data from the tablet's sensors into the app. However, I have been unable to find any examples of how to send the data out of the app to the drone itself. I would like to use the mavlink command att_pos_mocap (number 138) as I have the necessary info ready to put in. Can anyone give me any direction on how to implement this? I have looked extensively, but the only similar examples I can find are for python applications. I found the experimental SendMavlinkMessage() option, but have no idea how to create the needed messageWrapper it calls for. This is by far the most programming I've done so any help would be much appreciated and help me finish this term project for school! Thanks!
