@george-kollamkulam , something seems fishy here.

The Starling 2 drone has the VOXL Mini ESC, which acts as the APM (measures voltage and total current). The ESC sends this data to PX4 via UART together with regular ESC telelmetry.

The Battery status packet is an uint16 with 0.001V resolution, so the maximum voltage it could report would be about 65V (2^16 millivolts).

packet definition:
https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/actuators/voxl_esc/qc_esc_packet.h#L157

packet parsing:
https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/actuators/voxl_esc/voxl_esc.cpp#L577

I suspect something else is going on. Maybe you need to choose a different Source for the battery monitoring (not Power Module)?

Is this voltage 267.55V updating or just stuck at that value?

@Aaron-Porter thanks for checking in. I'm able to see all the camera related ros2 topics now on the UAV and the laptop terminals.

Cheers,

@george-kollamkulam Here's voxl-logger https://docs.modalai.com/voxl-logger/ which you can use to record data. if you need to access the data real-time, that's a good source code starting point for how to capture the data into your application

@george-kollamkulam

Where are you getting the image / ROS2 packages? Is this an image that ModalAI maintains?

Just looking at the error, it seems like it can't find the yaml-cpp package. It could be that it's not installed correctly or something's wrong in your CMakeLists.txt. It looks like the yaml-cpp readme has some info for including it in your CMake project.

If you're using camera_calibration_parsers from image common, it might be worth bringing the issue up there.

Let me know if that helps,
Ted

@george-kollamkulam , in order to install the updated libmodal-journal package, you just download the file that i linked to VOXL2, lets say you put it in /home/root/.

Then, using adb you go to /home/root and execute:

dpkg -i libmodal-journal_0.2.6-202505081055_arm64.deb

Then you just run voxl-camera-server -l and you should see a lot more information being printed.

@george-kollamkulam That port is internally connected to the 5V coming from the main VOXL2 power (which is technically 5V 6A). Obviously you would be limited by the connector pins, which are rated around 1A max continuous. Also, drawing too much from this pin, can bring down the whole VOXL2 (if that 5V output on J19 is shorted to GND, for example).
