Did you update these with values suitable for your network?

// Update these with values suitable for your network.
byte mac[]    = {  0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
IPAddress ip(172, 16, 0, 100);
IPAddress server(172, 16, 0, 2);

What did you publish on topic "inTopic"?      client.subscribe("inTopic");

Your Arduino is publishing "hello world" on topic "outTopic" and has subscribed to topic "inTopic". Until something is published on topic "inTopic" your Arduino won't receive it.

Thanx alot sir..:slight_smile:
