-Connected to Betaflight and placed reciever in binding mode, FC shows ~~rapid ~~ double-blinking blue LED.
-Run Luna script on EdgeTx and selected <bind>, Rapid blinking LED turns into slow(1hz) blinking LED. Axes briefly jerk around in betaflight but no control of from transmitter.
-Flashed Transmitter in ELRS Configurator via com port.
-Tried flashing receiver via passthrough using com port but it failed with error " RX Serial not found ."
-Tried placing FC in bootloader mode but Configurator still does not recognize it.
-FC will not enter wifi mode, just slow blinks until battery dies.
Been at this all night, could I be missing something simple?
Thanks

it won't bind when it's already in wifi mode

#

double-blink is bind mode..
it only activates if the receiver has no set binding phrase..

#

RX Serial Not Found means you've not set ports tab properly

#

(Serial RX is not set to any uart)

#

which Exact receiver does it have? are you checking the correct LED?

eager tendon
#

Yes I should've said 'Double Flashing" not "Rapid flashing."

patent iris
#

receiver and tx module should be in the same Major firmware version to bind..

eager tendon
#

STM32F411

#

is the flight controller

patent iris
#

I'm asking about the receiver

eager tendon
#

Flight Controller: STM32F411, 6A BLHeli_S, 1-2S Integrated ELRS (2.4G)

#

i thought it was integrated into the FC

patent iris
#

could you connect drone to betaflight configurator, go into CLI tab and execute the command version
post the output here

eager tendon
#

I've been trying to verify receiver firmware version but I keep getting referred to the wifi, which isn't working, maybe becaue binding phrase is set

#

version

Betaflight / STM32F411 (S411) 4.4.2 Jun 1 2023 / 02:19:20 (23d066d08) MSP API: 1.45

###ERROR IN version: NO CONFIG FOUND#### board: manufacturer_id: EMAX, board_name: EMAX_TINYHAWKF4SX1280

patent iris
#

EMAX_TINYHAWKF4SX1280

#

so it doesn't have wifi because it's !spi

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

SPI Receivers - ExpressLRS

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

I'll flash betaflight then

patent iris
#

set a binding phrase, the same that's on the radio that's already on 3.3.x, then make sure tx module is set to one of the supported packet rates

eager tendon
#

so elrs on receiver is up to date. I set binding phrase up on rx/tx. strange

#

I havepacket rates high. I'll look into that

#

omg ty so much

#

it was the packet rates

#

You guys are awesome. I appreciate your time.
