Run JmavSim in HITL Mode

[anujkumargupta]

I am trying to run Jmavsim in HITL mode. I follwed the link https://pixhawk.org/dev/hil/jmavsim and used /dev/ttyACM0(Pixhawk connected through usb(serial)) and /dev/ttyUSB0(Pixhawk connected through radio telemetry(udp)) and as mention in link ttyusbmodem1 but every time it throws serial port exception either port not found or port busy.

Thanks.

Is QGroundControl running?

[anujkumargupta]

Yes its running. I followed the same instructions as mentioned in link in my last comment.

It's probably QGroundControl autoconnecting first. Kill QGroundControl, start jmavsim, then start QGC (if needed).

[anujkumargupta]

Thanks , Now it does not throw that error but its not showing any mavlink messages in terminal. Even its not showing the init mavlink.

What do you get?

[anujkumargupta]

I got this.

I first started the jmavsim then QGC. Thanks

I don't think I quite follow how you've connected with /dev/ttyUSB0 and the telemetry radio.

Can you try with only the usb connection? /dev/ttyACM0

@DrTon I have tuned my quad on JmavSim and works very weel on Simulation. the problem is when i write the PID parameters on Pixhwak to test flight . the quad behaves weirdly please find the link for the video : https://www.dropbox.com/s/chxxrwyg2n9kuug/video-1487278360.mp4?dl=0
