ESP8266 Community Forum

I used the sample sketch provided with "PubSubClient /mqtt_esp8266" to send a string as topics and sure enough, with the minimum changes to the sketch (Only added UID, credentials and topic to distinguish between the two esp8266's,

the communication stops when a second NodeMCU is connected (powered up).

In this topic on the forum:
viewtopic.php?f=160&t=17706&p=0&e=0

I described my prototype attempt but my reply with more info seems to disappear.

I am more than will to share my test code to prove it.

Any help will greatly be appreciated

Solved:
When client.connect, each ESP8266 should have a unique ClientID.
I used the same sketch and not changing the ClientID
