@jonathankampia Correct, The VectorNAV needs to have the serial port implementation changed to support SLPI. That can either be done by modifying the code on our branch or going to mainline PX4 and modifying the implementation to use the platform independent Serial port abstraction.

it's more likely I will be commanding attitude / body rate which are already available

Indeed. I highly suggest you to use those two unless your application stricly requires direct actuation control.

I just wanted to get a clear overview of what the information dds client / agent can give me access to in the modalai version of px4.

By editing src/modules/microdds_client/dds_topics.yaml you can access any PX4 uorb message so the limit here is just about what has been implemented on PX4 that is or is not available in the voxl version.

How do you know what types of control / input & output data are not directly supported in px4 voxl version, as you said?

the type of offboard control you can achieve is exposed by OffboardControlMode.msg. As you can see in main PX4 you have

bool position bool velocity bool acceleration bool attitude bool body_rate bool thrust_and_torque bool direct_actuator

I've added thrust_and_torque and direct_actuator one year ago (more or less). However, latest voxl is still using the old version: this old version let's you control via thrust and torque setpoints but does not let you control the single motor individually.

@jonathankampia Unfortunately, the hard part is creating the build Docker.

@Gary-Holmgren Haha your way is a little more robust than mine. I just manually added the qshell start command to the extra commands section of the voxl-px4.conf file.

@jonathankampia , sorry for the delay, please see the response in this post https://forum.modalai.com/topic/3952/flir-boson-beta-hardware

@jonathankampia , were you able to first confirm that you can control the gimbal using the actuator test in QGC for the pwm channel 5 (make sure to remove propellers for testing, just in case)? it should work just like any other pwm channel, i am assuming you already have channels 1-4 already set up and working with ESCs?

If PWM actuator test is working through QGC, then you have VOXL2 IO board set up correctly and the rest of the logic for actually driving the pwm signal should be the same as for regular PX4 drone (which does not use VOXL).

At the end of the day, the VOXL2 IO driver receives 8 channel values from the mixer and just sends the desired pwm values out to the VOXL2 IO board. All the logic above the mixer is standard PX4 and if you have a question about that, you can also try the PX4 forum (since we are not necessarily the best PX4 experts).

You can try your python script, make sure propellers are off until you know exactly what you are doing and are ready to fly 🙂

@jonathankampia Edit: managed to fix it by disabling voxl-configure-modem and manually setting the IP of the eth0 interface. I guess 'eth1' is the J11 connector then.

@Zachary-Lowell-0 Hi, sorry for the late reply. This was the issue (lol)

@Alex-Kushleyev I never uploaded any parameters, just used both escs out of the box. maybe that caused the issue?

@jonathankampia Yes, it would require modifying the "tones" in whichever esc param file you're using. For example for starling 2 it is defined here: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-params/D0014_starling_1504_3000kv_ms_props/D0014_starling_1504_3000kv_ms_props.xml?ref_type=heads#L90

@jonathankampia Yes, both qmc5883l and ist8310 are supported now.

@Eric-Katzfey The EKF2_EV_CTRL param is set to 15 bits (all enabled). We don't have any cameras on the drone at the moment, though. Could that be introducing issues in the EKF2 and causing it to reset? I'll try disabling all vision stuff and see if it works different.

@jonathankampia We only add drivers to the build that we have used and tested with. The ll40ls driver is not one of them so you would have to add that to the build yourself.

@jonathankampia You could run UART based comms like an external flight controller on that UART: https://docs.modalai.com/voxl2-external-flight-controller/

but no you couldn't connect a USB device there

Tested on 1.12.2, seeing same issue

@jonathankampia Did you solve this issue?
