Post the full sketch that you are using and details of your hardware
the hardware used is esp32 wroom 32D
the intention of this mqtt is to send data that have been coded in the esp that is connected with hcsr04 ultrasonic sensor then transfering it to the mqtt as a broker before being displayed using node red as the iot dashboard
