mqttClient.publish ESP32

AndrejK

Hi!

I'm trying to 'publish' a Label Update command with an integer variable/value.

I'm passing an integer variable from main program (.ino), where I measure temeprature with DS18S20, to programm_sta.cpp, where the GUI-O user code shall be integrated.

Hovewer, I do not know how to use following command:

mqttClient.publish(parameters.publishTopic, "@lb8 TXT:"\MYTEXT"\r\n");

where 'MYTEXT' should be an integer value or it's string representation of my measured temperature value.

Thanks in advance for any help.
