#ELRS SPI receiver not binding

Hi,
I am trying to bind my ELRS spi receiver to my radio master zorro tx. I am using the happy model f4 aio with the spi ELRS receiver. I press the bind button in the receiver tab of betaflight, and then press the bind button on the tx. The fc beeps a bit and the drone on the receiver tab does a flip, but the rx and tx do not bind. I also made sure the binding phrases on the rx and tx are the same. Why is this not working?

Flight controllers with built-in ELRS SPI receivers are not flashed using ELRS Configurator, the ELRS firmware is "baked in" to Betaflight. Thus to update your ELRS firmware, you'll need to flash the latest version of Betaflight for your FC. Betaflight 4.3.x is compatible with ELRS v2.x.x, and Betaflight 4.4.x is compatible with ELRS v3.x.x.
In Betaflight 4.4 and newer, the binding phrase can be set directly on the receiver tab in Betaflight Configurator.
In Betaflight 4.3, the binding phrase needs to be set via CLI. Enter it here and paste the resulting code in the Betaflight CLI: https://www.expresslrs.org/hardware/spi-receivers/#binding-phrase

All-in-one Flight Controllers were released with ExpressLRS receivers using SPI connection.

What packet rate do you have set in the ELRS lua?

#

No need to select bind if you are using a binding phrase, they will connect automatically

Any supported packet rate

500Hz is fine

Not D500 or F500 though
