@Muqing-Cao Just the standard Mavlink ODOMETRY message is what we have used. Not exactly sure how that translates into ROS land. But it isn't anything ModalAI specific.

@latif You should be able to disable the model match feature on the same screen which displayed the "Model Mismatch" error. By setting the model match id to 0, it will ignore the model match id set on the receiver and connect. The ExpressLRS documentation has more detail about how to set up the RC connection here.

@Muqing-Cao Yes, definitely. The applications are auto started using systemd services and can be stopped / disabled using standard commands as desired.

@ashley-miller , for this motor (28xx class), you should use the following ESC M0138 FPV ESC :

https://www.modalai.com/products/m0138
https://docs.modalai.com/voxl-fpv-esc-datasheet/

The mini ESC (M0129) is designed for small and lightweight drones and mini FPV racers (750g or less for slow flyers and 500g or less for mini FPV drones).

The peak power for one of these motor is almost 1kW each - the mini ESC cannot handle that for several reasons, such as peak current capacity, thermal.

If you would like to use the 2808 motor, please choose the M0138 FPV ESC and perform motor calibration using voxl-esc tools : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/calibration.md

Also, please review the following FAQ: https://docs.modalai.com/voxl-escs/faq/

@Hunter-Scott The log you provided contained battery_status

@latif You'll want to load the GPS specific px4 param file in order for "position" mode to use GPS position as opposed to VIO position.

If you run voxl-configure-px4-params -w and navigate to EKF2_helpers you should be able to see the relevant options.

@latif What do you see if you run voxl-check-calibration?

It sometimes takes a while to get a GPS lock for the first time in a new location, may have to let the drone sit outside for 5-10 minutes for the initial lock, will be much faster after that.

@latif You should be able to go into /var and see what's full and deleting it
