Where to find the list of MAVLINK msgs supported and publishing frequency
Hi!
I just found this interesting project and trying to understand the possibility of its usage for drone control to fly along a given trajectory with ROS from PC.
Where could I get the list of data I could obtain? Could I get the position, orientation, linear and angular velocity? What is the frequency of this data? Could it be 50 Hz or something like this? How I could control the drone?
Thanks a lot!
Looks like I could find whar rosettadrone receives and sends in app/src/main/java/sq/rogue/rosettadrone/MAVLinkReceiver.java and app/src/main/java/sq/rogue/rosettadrone/DroneModel.java
Am I right that maximum frequency is 10Hz? (according to void tick() { // Called ever 100ms...)?
Yes, can be changed if you need faster updates, but it is a CPU tradeoff.

Thanks for answering! According to your practice, does Mobile SDK itself let to get new data at a frequency around 50 Hz?
I did not try but it can be set. However I fly using computer vision AI in a PC on the ground and Dronekit as a controller all the time, and 10Hz is no problem, remember the drone is actually flying, all you need to to correct it’s heading/altitude/direction etc. Unless you whant to fly very fast, then 50Hz make sense.
