ESP8266 Community Forum

Hi,
I am wondering, if someone knows about this problem and might give me a hint.

I have TWO ESP8266 Nodemcu v 0.9 modules conntected to my local WiFi router.
WiFi connection works well - no issue.

On both modules I have an MQTT Client installed. Each of them works smoothly and stable.
The moment I switch on the second module, trying to connect to the same MQTT broker, the first module gets dropped off and - in my case - re-boots. The same happens to the second module once the first is trying to connect and so one.

It looks to me like a data package collision... ?

Looking forward to your replies

Thanks Daniel

Hi Daniel,

My Name is Pal,

I am working on the same the same.
You may need to check 2 things.
If you use the same code in both borads, then chk the client id.
2. check the timer identification numbers.
or possible post your code here, and let me see.

Thanks,
Pal.
