I don’t have this board on hand, but some searching on the inet says, that WiFi has some extremely low range, maybe only a few centimeters from the board. Try put your phone as close to the board as possible and then search for the “ExpressLRS RX” WiFi access point.
The Betaflight serial passthrough might be the other option. Keep the “RC boot” button pressed while powering the board to put the receiver ESP chip into the bootloader mode. Also you might have to hold down *both* buttons on the FC when you plug in USB as per some user advice.
It seems like the elrs cannot be flashed through WiFi although they have the esp chip onboard.
]]>First make sure you have the same FW version on the receiver and transmitter module. Then make sure you have flashed the firmware with the same passphrase. This should be enough for the receiver to bind automagically.
