i am doing my project with Visuino Pro Programming software, and i am not able to connect the TCP Port: 1883 to blynk.cloud. every time giving error bad username and password, and also connecting/disconnecting continuously going on.
Please suggest me, if i missing something
i am using the hardware ESP32 But not though arduino IDE
1883 is the MQTT port, so I assume that you are trying to establish an MQTT connection.
Have you read the documentation…
Note that the username is literally the word “device”, you don’t substitute “device” for anything else.

Respected sir, I did my best to best, as per your given link of documents, but i am sure it is not connecting at any how. The connection getting error always. Used port:1883 to blynk.cloud user name as my device name and password is the authentication token. But it is not connecting.
I have only option TCP Port clint, and TCP port SSL client. From 3days i am continuously trying but its not connecting
And that is exactly what you should not be doing.
I thought I’d spelled it out very clearly, the user name is the word “device”.
Exactly that, “device”, not the name you’ve given your device, but the word “device”
Do you understand now that the user name is “device”?

Respected sir, thanks a lot for guiding, it is working properly with username :- device, thank you very much, now my problem is solved.
Respected sir,
If I Create the second number of device, then what user name i use to control for the second number of device data only ?.
thank you
The username is always “device”.
The second device will have a different Auth token, which will be used as the password for that connection.
Pete.
Thank You Very much sir, for this imp information
