Hey guys what is a good software package for the pixhawk that includes SLAM and path planning algorithms? I'm trying to look into path planning algorithms that use machine learning and I so want to get a standard implementation of autonomous planning after which I can modify the path planning algorithms.

Actually the problem is if I upload the latest stable release from QGC via "firmware -> PX4 Flightstack -> stable release" QGC does all the procedures(download + erase + upload). But when board reboots, somehow it restores previous uploaded version(Or QGC fakes everything). But if I upload the firmware by downloading releases from github and doing "firmware -> PX4 Flightstack -> custom firmware" everything works just fine. Is it a QGC bug?

Encountering a silly problem. I have downloaded the latest daily build of QGC(2017-06-17) and from there installed PX4 firmware v1.6.3 into my board. But after rebooting in the summary tab QGC is showing my firmware version as v1.6.1dev. What is the problem? How can I be sure about my firmware version?

I concur. Mine was QGroundControl Development HEAD:54c92f75c 2017-06-22 02:20:17 -0300. I decided to try Custom Firmware so I downloaded the Stable Firmware.zip but there are 13 PX4 files in there. Which one is the stable verison for Quad Plane and Quad Ranger? Any assistance or direction is highly appreciated.

Hi, I'm working with px4 for NuttX (Pixhawk) and while I'm compiling, all warnings are treated as errors, how can I turn this behaviour off (not for contributing, but for developing by myself)?

Hello everyone, has anyone tried this long Wi-fi Broadcast as instructed on the Dev Guide? Although I have managed to set up the wi-fi antennas as instructed and receiving UDP packets from the TX, I can't seem to display the video on the RX side. Is it possible that the person who have written the page has more info on this topic???

Hi everybody,I have question about read RPM of OS motor in mission planner. For test I connect pwm of rc receiver to AUX 5 and enable RPM1, but I can't read it. Dose anyone work correctly or can help me?
Is the pwm of rc receiver different between rpm sensor?

I forgot that to tell, I disabled Relay parameter for AUX5

Can anyone tell me what could have been wrong with this accident: http://bit.ly/2vfFkM7 - The Octocopter just flipped. ESCs were calibrated. I checked the CW/CCW configuration, seems right. Pixhawk calibration seemed right. Hopefully someone experienced can tell what went wrong?

Hi, at the moment, we have a lot of trouble to flash the pixracer out of a Ubuntu virtual machine or from Windows. It doesn't matter, if we use the upload command or QGroundControl. It stops during the upload phase nearly all the time. Only a pure Ubuntu version works. Did anybody have a workaround for that problem?
