Betaflight Firmware and CLI
Since Betaflight has not yet released the official firmware that could supports the SPI ExpressLRS protocol, the current version is the Beta version. Please use the firmware and the CLI dump file below to recovery the FC board if needed. Betaflight will update to their official target soon. Please feel free to contact with us if you have any issues with this Beta version Firmware.
It is normal that there is no any option on Betaflight Configurator Receiver. As show below, the checkbox is blank.

Please change the “PID loop frequency” to “4KHZ” , sometimes it would make the SPI receiver not working correct while the value is “8KHZ”.

Download the firmware and CLI dump file for the F4 1S 5A FC (ELRS 2.4G) board.
