I've had the exact same bad altitude problem on my quad (w/PX4Flow and Lidar Lite). Same as you, I've had the altitude value slowly/steadily climb while the quad is sitting on the bench and while hovering as well (at a height 1-3 meters).…"
"Great work Daniel. Did you use any kind of vibration dampening (or gimbal) to help keep the c920 from producing "jello-like" video or was it able to focus on the concentric circles with the camera just hard mounted to the frame? "
"@Bim I have a similar situation. I'm trying to fly an quad indoors with an Optical Flow sensor (PX4Flow) and a Rangefinder (LIDAR Lite) using the 3.3RC10 firmware. I'm able to takeoff in Loiter mode (which, from what I understand, is the only…"
"Was having the same problem -- thanks so much for posting this! I couldn't find this anywhere.
For anyone else that happens upon this, MAVproxy "listens" on a random UDP port that (per above) you can determine from any message that MAVproxy sends…"
"Really cool project. When using my rover in my yard, I've had so many drive aways using my APM 2.6 that I'm looking to use my dog's underground fence receiver collar as an independent geofence failsafe (before I put any additional hardware on the…"
Can anyone point me in the right direction to purchase a modest tether system for multi-rotor aircraft (or instructions for building one) to aid in safely testing code while airborne? I need a system that will eliminate the need for batteries…
"I've encountered situations where, when re-opening a serial connection to the Pixhawk in Linux using mavutil, the Pixhawk will simply stop providing data and the mavutil function recv_msg() will endlessly return "None". It seems like the Pixhawk's…"
"Thanks for posting this. I'm interested in your blog post "Pixhawk's serial device named automatically"... does this technique dynamically re-assign the Pixhawk to /dev/pixhawk if the pixhawk crashes and comes back as a different serial device name…"
"I'd be curious to know this as well... Can the Pixhawk accept local data (e.g. Camera images from the pi) to send out via the Pixhawk's telemetry_2 port? I think most people in this scenario are using GSM or Wi-FI on the Pi to send out camera data,…"
"It seemed pretty straightforward to get my Pixhawk recognized in my python script using pymavlink. Can you paste your code and the error message you're getting? Similar to the other comments in this thread, after you install pymavlink, you should…"
Is there any way to change how often qGroundControl expects to receive a heartbeat message from the APM?I saw this note in the Developer's Section, but I still don't see a setting in qGroundControl to change the expected Heartbeat rate. MAVLink is…
