1.use 6P line connects to pixhawk flight controller.
Due to the different firmware, some firmware, two ports can be used, some firmware can only use one of the ports. So find one of the available ports for the connection.
IF you use PX4 firmware ,only TELEM1 can be used ,can not use TELEM2.(please NOTE, only TELEM1 can be used)
IF you use ardupilot firmware, find one of the available ports for the connection.
- When using Radio Telemetry connection, it must use 3DR Power Module or 5V ESC to supply power to the flight control. USB cannot be inserted because USB priority is higher than Radio Telemetry . If USB cable is plugged in, it cannot be used for digital transmission.
- The default baud rate of the Radio Telemetry is 57600, not 115200. Select the correct COM port and do not select AUTO.
- If there is a driver problem, download from here:pix.rctoysky.com/CP210x_VCP_Windows.rar
3. Do not set TX POWER of AIR Radio Telemetry as 20,defaut is 11, no need to modify.Too high TX POWER will interfere with GPS satellite search, remote control distance, ESC distance, etc.
