Telemetry Setting

  • Port
  • TCP telemetry server port, Ground Control Station can connect to this port via TCP to get telemetry data, default is 5760

    Change port number and click "Restart" button to change TCP server port

  • Connection
  • Telemetry data is relayed through internet in 2 connections method:

    • UDP to archive minimize latency (possible packet loss, suitable for Joystick mode)
    • TCP method to achieve high reliability

Camera Setting

  • Host Port
  • Destination video port, Mission Planner and QGroundControl supports video in HUD by default on port 5600

  • Video source
  • Video device, default is /dev/video0

  • Relay to
  • Relay video streaming to another destination, syntax: xxx.xxx.xxx.xxx:port2;yyy.yyy.yyy.yyy:port2

    For example:

    • Share video streaming to ip 10.0.10.4 at port 5602, just type: 10.0.10.4:5602
    • Share video streaming to ip 10.0.0.4 at port 5602 and 192.168.1.4 at port 5603, type: 10.0.10.4:5602;192.168.1.4:5603
  • Video Quality
    • Auto: Video streaming is start with auto quality (300x200 pixels and 90fps with Pi camera v2)
    • Manual
      • FPS: Frame per second
      • Bitrate: number of bits that can be either sent or received per time unit (kbps), default 0 is auto
      • Resolution

Note: For changing camera setting, you need to Turn OFF camera and Turn ON camera again to apply the change

Serial Setting

"Port" field allows you to choose serial port on companion computer

NOTE: The companion computer will show all available port (ttyS0, ttyUSB0, ttyUSB1…). You have to choose exactly serial port. If you don’t know name port, you can try them one by one.

With Rasp pi:

  • Choose ttyS0 (default) when you connect pi – pix via Direct Cable or Stable Power Module
  • Choose ttyUSB0 when you connect pi – pix via USART USB

"Baudrate" allows you to choose serial baudrate on companion computer

NOTE: The baudrate on companion computer have to same the baudrate (telemetry 2) on Pixhawk

  • With PX4: SER_TEL2_BAUD (Default 921600), you should change 57600 for stable and save data.
  • With ArduPilot: SERIAL2_BAUD (Default 57, it means 57600), SERIAL2_PROTOCOL: 2 (mavlink 2)
