CONNECT MQTT.TCP_Flag = True

But i cant publish and subscribe. if (MQTT.available()) { Serial.println("MQTT available..."); } also this is not working, i never get the message "MQTT available..." on my serial. Please can anyone help me? (SIM800L with ESP32 via HardwareSerial UART2)

Dear @Franciscopcosta I'm having the same problem, did you made any improvement?

Serial pins Rx and Tx work with SIM800 module. This library uses software serial "mySerial" Change Serial.println("MQTT available..."); with mySerial.println("MQTT available..."); Conect an external usb/serial driver to software serial pins, it works for me.
