nrf24l01 module installed but can't bind to h8 min

Hello everyone, i recently completed my modification of the devo 7e with the nrf24l01 module. When i try to bind to my eachine h8 mini, using the bayang protocol, the quads light begin to flash as if it's binding after the first beep, but then the lights begin to blink slowly in intervals of 5. Any ideas?

Did you check the quads battery power?

I have the same problem. When initiating bind, the frequency of LED blinking changes, but then I cannot control the quad. I have the 3in1 RF module from Banggood installed. My H8 Mini has the blue board with stock firmware.
