@Jetson-Nano VOXL 2 does not have PWM out. You would need our IO expander board M0065 to bridge between UART and PWM. https://www.modalai.com/products/voxl2-io?variant=40610514206771
@Raza-Rizvi That error message "voxl-mavlink-server does not appear to be running" isn't normal. You may want to run through voxl-configure-mpa again, set your host IP in voxl-vision-px4.conf, then reboot your drone.
