- Press and hold the bind button of the receiver, then power on for the Speki+ receiver.(Usually we can connect the receiver to the flight controller, and plug the usb to power up for the receiver)
- The Red LED start to blinking fast, this indicate the receiver is in bind mode
- Make your radio transmitter get into bind mode. If the red LED on the receiver turned off ,this indicate bind is successful then quit bind mode for the radio transmitter
- The red LED on the Speki+ receiver is solid , now the radio transmitter and the receiver are working fine.
Make sure the “Telemetry” was enable from the Betaflight Configurator, otherwise the receiver will not work.
Please set AUX8 for the RSSI Channel
The receiver signal should be connected to idle port and enable Serial_rx for this UART port. If you connect to TX1 then you should enable serial_rx for UART1.
