@tom SOLVED, thanks Tom, that command line prompt showed me that I needed to voxl-configure-extrinsics. Thank you!

@tom We're running v1.0.1 SDK. However, we were actually just able to get the RTSP stream working over Herelink with virtually no latency. Using the SiYiQgroundControl application on the Herelink, the RTSP works completely fine. I believe the issue is in the QGC firmware that ships stock with the Herelink controller. For now you can consider this thread solved. Thanks again!

@Eric-Katzfey Dronetag DRI, It expects to accept MAVLink data from the flight controller.

@Vinny Appreciate the heads up

@Zachary-Lowell-0 I'm attempting to communicate through the UART ttyHS1 that is made available on the USB expansion board.

I'm looking to establish an external MAVLink connection to the voxl-px4 service on VOXL 2 through the ttyHS1 of the USB3 expansion board. I'm looking to integrate a third party RemoteID module, and am not implementing an external flight controller.

All the documentation and questions on the forum I could find seem to reference an external flight controller use case, or an internal MAVROS/MAVSDK use case. How do I go about configuring the mavlink-server to output MAVLink on this external UART while maintaining the VOXL 2's PX4 capability.

@valvarez Any PWM based servo should work, we're using 5g servos with very little torque capability and haven't seen any issues with the power supply capabilities of the IO board in this regard. I connected the PWM Signal to output 1 on the IO board and the 5V and G of the same port. Has been working consistently through QGC.

Currently using the VOXL IO board for PWM control on the VOXL 2 using SDK 1.3.5, I am beginning to integrate the FPV ESC and noticed that it has listed PWM output capabilities. If I can remove the VOXL IO board from the loop that would be ideal from a SWaP perspective. However, there is little documentation on how to get the PWM control to work through PX4 outside of what is listed in the test script. Has PWM output on the ESCs been fully integrated, separate from the ESC control which we would prefer to keep over the UART. Or, is the VOXL IO board still the only way to integrate PWM control out of the box with the Modal AI ecosystem? PWM control will be used for Payload control specifically.

@tom Looks like I just needed to update the ESC firmware to the latest variant, that got the python script to work, still working on PX4 though, I'm using Joystick controls through QGC rather than an RC radio so I cannot Map an RC channel, using the actuator testing panel instead and set GPIO_CTL_CH = 3 and RC AUX 3 to one of the outputs, doesn't seem to be triggering the LED yet but I'm not sure if RC AUX 3 sends the same message as with a RC Controller, going to try going through the VOXL IO functionality instead of the ESC output next. In the end, we'll just be integrating it into our custom QGC fork, however want to test it before going through the effort.

@tom Seems like neither the voxl-esc-gpio.py test script or the PX4 triggering via RC_AUX seems to be having an effect on the PF0 GPIO on the ESC. Currently, I am using SDK 1.3.5. I did notice that the voxl-esc-gpio.py has the packet = wrap_data(ESC_PACKET_TYPE_GPIO_CMD,req_data) line commented out, is there anything else that I should check? Perhaps a different ESC firmware?

@Alex-Kushleyev Yeah, even if we can't trigger it through PX4, having to stop voxl-px4 will not work

@Alex-Kushleyev I'm specifically interested in toggling the VTX on/off GPIO on the ESC as described in the attached image.
