Controlling quadcopter through wifi

I am using an arduino nano as my quadcopter flight controller with multiWii. I am giving in the ppm signal from a customized mobile app through a nodemcu esp8266, thus giving me wifi control.i have checked through browser that my nano is receiving the signals but the esc are not responding. What could have gone wrong?

Hey! Did it work without the Wi-Fi module? It’s good practice to test modules on their own and isolate the problem.
