If you see the examples, you have to declare client as WiFiSocken and use client.Stream as first parameter.

B4X: 
Sub Process_Globals
    Private client As WiFiSocket
End Sub

What is the client id and where do I find it? | CloudMQTT

We get a lot of questions about what the client id is and where it can be found. This short article will hopefully help you during your MQTT journey.

Thank you All... I am able to publish the message at CloudMQTT.
The only issue is I am able to put any counter value at the Publish function.
B4X: 
mqttclient.Publish("esp","thank you for your m-ESP")
How Can I put a counter after ESP string?

Try something like:

B4X: 
mqttclient.Publish("esp","thank you for your m-ESP number: " & counterValue)

Sorry, I was thinking in B4A.
If I'm not wrong, try this:

B4X: 
Private Sub mtimer_Tick
  counter = counter+1
  Dim b() As Byte = "thank you for your m-ESP: " & counter
  mqttclient.Publish("esp",b)
End Sub

Please, use [code]...paste your code here...[/code] to show your code

Super....Its Working.....
If I will use GSM SIM 800 instead of WiFi [ESP8266] to connect to CloudMQTT, then should I declare the client same as before ? like below
B4X: 
Private client As WiFiSocket
Please advice.....
