My APP is sending UDP packets to nodeMCU ESP8266. I am sending some packets (message "Hello") to ESP8266. However, packets are not reaching to ESP8266 (I am observing on Arduino's serial monitor).
I am not able to recognize whether ESP8266 is not able to receive packets or APP is not sending packets. Please help me to find out root cause of it.
