Android Question Sending UDP packets

[Nitin Joshi]

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.

You already made this question a few times.

You can debug it by creating a B4J program that listens to the UDP packets on the PC.
