Smartphone Connection Telemetry Module with Pixhawk - Wi-Fi 2.0

Due to different firmware, some firmware can use two ports, some firmware can only use one of the ports. So find one of the available ports for connection. If you are using PX4 firmware, only TELEM1 can be used, you cannot use telem2. It is recommended to use the TELEM2 port for Ardupilot firmware. Or find one of the available ports for connection. For PX4 firmware, you must use the TELEM1 port.

How to use?

When using wifi radio telemetry connection, it should use 3DR power module or 5V ESC to power supply to flight control. USB cannot be added because USB priority is higher than radio telemetry. If the USB cable is plugged in, the radio cannot be used for telemetry transmission.
