"How do I get data other than #0 and #253? APM does not give me the necessary data."

"the mission planner doesnt currently decode that message. it does decode MAVLINK_MSG_ID_RAW_IMU and MAVLINK_MSG_ID_SCALED_IMU though  "

"Thank you Mr. Oborne for the answer. I'm using Free Serial Port monitor vesrion 3.31 from HHD Software to sniff the communications between APM and the autopilot. I attached a screen snapshot with some messages sent by APM. As you notice, all…"

"the mission planner has a hardcoded 0xfe as the packet start. and does conform to the mavlink specs. so am not sure how you are seeing what your seeing"

Problem with APM mission planner & Mavlink protocol

Hi all,I repost here the same question I've posted to the ArduPlane user's group.I'm trying to connect my STM32 based autopilot with the APM mission planner 1.2.22 Mav 1.0, with a pair of 3D Robotics 433 MHz radios, without success.The APM recognizes the heartbeat messages sent by the autopilot but doesn't complete the connection.After some tweaking I traced the problem back to the REQUEST PARAM LIST message sent by APM planner: contrary to the…See More

"Hi Doug, Wow ! Flight testing UAV autopilots ! I can't disguise some envy. Thanks for the explanation, my knowledge of PID control dates some 20 years back and I wasn't that lucky to use them in my every days' job. My guess was that a…"

At last it worked ! Here's a short video, not high quality indeed. Hope it is intelligible.

What method did you use to build the RQ-7 Shadow replica in your photos. It looks amazing.

Very cool. Thanks for the information. I have to say I am impressed by the use of arrows, they seem like a perfect solution to your tail boom. I plan on using carbon fiber rods from rcfoam.com for mine. How did you get the mold? is my last question (that and how well does it fly?). The body work (around the engine is my fav) looks so clean. Keep the photos coming!
