Note: Now the officially released Betaflight does not support SPI ELRS 2.4G receiver, so please use the following test version of the firmware, and use the corresponding configuration CLI.
This CLI can be used for F4 1S AIO 12A FC(ELRS 2.4G V2.0) which is fit for Betaflight_4.3.0_STM32F411_norevision firmware. The picture is marked as 1, the CLI file for the FC is named BTFL_cli_F4 12A ELRS_V2.0 and the firmware file is named BTFL_4.3.0_STM32F411_norevision
New released firmware BTFL_4.3.0_BETAFPVF4SX1280_0265565fa uses external GPIO interrupt triggers to process ELRS data reception, increasing the stability of the signal link. Now it can perfectly support LiteRadio2 SE 500Hz link and modify the accuracy of signal strength.
The new CLI file is named BTFL_cli_F4 12A ELRS_V2.0_NEW. Please check.
Note: The new firmware supports only ELRS 1.0.0, 1.0.1, 1.1.0, 1.2.0, 1.2.1.
