- By default, there are two connections from the TX1 to the PX4 enabled.
- /dev/ttyUSB1 on the TX1 goes to a 57600 baud UART on PX4 device /dev/ttyS1
- This is used as a Qgroundcontrol channel by default.
- /dev/ttyTHS2 on the TX1 goes to a 921600 baud UART on PX4 device /dev/ttyS2
- This is used by default for tealflightd.service on the TX1
- To use this for other processes, disable tealflightd.service with “sudo systemctl disable tealflightd.service”
- /dev/ttyUSB1 on the TX1 goes to a 57600 baud UART on PX4 device /dev/ttyS1
- By default, updating PX4 is done through the USB, but the mavlink USB stream is turned off on our build of PX4 to conserve RAM
- This connects to /dev/ttyACM0 on the TX1
