    the new features are very cool, but can't connect is upset.

    is it just me that trying Hil in jMAVSim but cannot switch to auto mission (it keeps rejecting the auto command)?

    Can anyone tell me where the black box data is located for the Simulator? Like after the flight I can get the black box data from the SD card inside the Pixhawk. Where is the SD card data located for the simulator ?

    @musclesinwood Here it is :

    PX4/Firmware/build_posix_sitl_default/src/firmware/posix/rootfs/fs/microsd/log

    Actually this page can point it out.

    Okay Thank You. I have one more question. I am trying to plot the data in the log file but when I choose different parameters to plot it I can not see any plot. I am using FlightPlot to plot the logged data. And selecting only those parameters where I am interested in.

    Could Anyone tell me Ardupilot(APM) can use JMAVSim tools ???
    Lorenz Meier
    @LorenzMeier
    @leomatrix I’m not aware that it supports it. But you can run PX4 with it (http://dev.px4.io/simulation-sitl.html) or AutoQuad

    Is it possible to change camera position and angle or are you locked to home
    Mark Whitehorn
    @kd0aij
    I played with that in my fork a long time ago: https://github.com/kd0aij/jMAVSim/tree/markw The functionality is probably still in master.
    Bryan Monti
    @bryanmonti
    Nice! Do you have any notes/docs about changing cam position in your fork or is it in the comments?

    @Aperture-Laboratories There are a bunch of keyboard shortcuts

    Not sure if it's what you wanted, but I was pointing the FPV camera at a moving target.
    Bryan Monti
    @bryanmonti
    Ah, yeah, was looking for that too. Might have to do something custom as I want it to pop up as a ROS node
    I want it to change according to my current position/setpoint. I kinda realized I should be using gazebo in addition to jMAVsim
    Is there a way to spawn multiple vehicles in the same world?
    Mark Whitehorn
    @kd0aij
    I don't see why not. It's completely object-oriented

    Hello,
    SaifOsa
    @SaifOsa
    I'm trying to do HIL with pixhawk, jmavsim, qgroundcontrol v3.0.2. I followed the tutorial in "http://uav-lab.org/2016/08/31/px4-research-log-8-hardware-in-the-loop-hitl-simulation-using-jmavsim-on-ubuntu-14-04/" I planned a mission on QGC, I send it to the quad, then I armed the quadrotor using RC in manual mode, and the quadrotor start taking off to a very high altitude and then crash down? Do you have any idea? I joined the jmavsim messages

    Hi all. I am planning to make a HIL setup of px4 with V-REP simulator. I need some help to know :

    • how to set the HIL mode in PX4?
    • what are the mavlink messages that are used to pass the sensor data from the simulator to px4 firmware?
    • what are the mavlink messages used to send actuator commands to the simulator?

    Thanks

    Mark Whitehorn
    @kd0aij
    @mzahana Start by grepping the source code (PX4/Firmware) for "HIL mode"
    Mohamed Abdelkader Zahana
    @mzahana
    @kd0aij Thanks. I guess, I got some hints on how to do this based on MAVROS.

    Hi guys. I need some help on how to simulate 3d magnetometer like in jmavsim. I would like to implement this in another simulator, V-REP. Thanks
    Lorenz Meier
    @LorenzMeier
    @mzahana We generally recommend Gazebo
    Its free and we support it by default including 3D sensors
    Mohamed Abdelkader Zahana
    @mzahana
    @LorenzMeier Gazebo is good, but not as user friendly as V-REP. I already implemented plugins for HIL_SENSOR and HIL_STATE_QUATERNION in mavros. This will allow HIL with any simulator that can talk to ROS, including V-REP. Now , I am working on the simulator side to send sensor data and receive actuator commands.

    @mzahana
    @DrTon I would like to know how jMAVSim converts the HIL_CONTROLS to rotors forces and torques. I am working on another HIL simulator interface, V-REP. I am done sending the sensors values from V-REP to Pixhawk. Currently, I am stuck in converting the HIL_CONTROLS message. Thanks.

    Hi Guys , i have been using JmavSim to tune my quad . the Virtual tuning are very different to flight tuning . any ideas how to fix my simulation ?
    @DrTon im getting this error : WARN [lib__ecl] EKF baro hgt timeout - reset to baro
    any idea why ?

    @mzahana Correct! DrTon is not longer with us.

    Is it possible to spoof a laser range finder or sonar in the jMAVSim SITL?
    Mohamed Abdelkader Zahana
    @mzahana
    @brdgtannj I am not sure about jMAVSim, but it's available in Gazebo, check https://dev.px4.io/simulation-ros-interface.html

    Hello! Is there a way to set the initial GPS position in jMAVsim without altering its source? (I see, that the default initial position is hardcoded in source)
    cs147
    @cs147
    Anyone familiar with setting up multiple UDP ports to control multiple vehicles in SITL jmavsim?
    cs147
    @cs147
    @bryanmonti Did you ever get multiple vehicles in same world working?

    I have an Armbian flavour ubuntu xenial on my oDroid xu4.

    Used the ubuntu_sim_ros_gazebo.sh script to setup my dev environment.

    When i run make posix jmavsim or source jmavsim_run.sh I get the following java.lang.UnsatisfiedLinkError

    The .so lib referenced, is not in the referenced folder. I believe its part of the JOGL framework. I read though that jMAVSim has all the necessary libraries.

    How do I fix this?

    Hey guys!
    I am new to dronekit.
    Have been trying to run my dronekit simple take off and land program on the JMavsim

    @SalauddinAliAh1_twitter
    i have no clue how to begin. I have the jmavsim running on port 14560
