( VOXL2 PX4 ROS2) MPA to ROS2 for Battery Voltage & Problems
-
Also @GlennTee build this branch of px4 and then flash onto your voxl2 - it exposes battery_status over the uorb topic through the dds bridge, so now when you run ros2 topic list you still see /fmu/out/battery_status: https://github.com/modalai/px4-firmware/tree/zach/battery_status_ros2
This is also a PR currently into voxl-dev branch of PX4 so most likely will be a feautre of the next release.

@GlennTee are you sourcing the right directory?
source /opt/ros/foxy/mpa_to_ros2/install/setup.bashthen run the command you mentioned above.Zach
@Zachary-Lowell-0 Hello. I just tried what you mentioned and I've had no luck so far. Below is my terminal window where I tried running both commands after sourcing.

@Zachary-Lowell-0 Would I need to wipe the drone and install the new build on to it? I also tried building your branch but I'm unsure about the location as where to put it, such as in /home/root, /opt/, etc., or if I need to use a specific build command other than "colcon build." Would you be able to clarify this? Thanks again for your help!

I just tried downloading it but there appears to be a package missing that is needed. I tried looking online to find somewhere to download it from but I couldn't really find anything. Do you know where I could find it?

@GlennTee Ah, I assumed you were on the latest SDK version. You really should be. Can you first update to SDK 1.4.x?

@Eric-Katzfey Hello again. I upgraded to SDK v1.4.1 and the downloaded worked this time. I am able to echo the battery_status topic and it shows all the information. Thank you so much. I do have another question, is there a way to get tag detection as a ros2 topic just like with battery_status?

@GlennTee Can you please start a separate post for each new question? Thanks!
