I need help connecting an ESP32 to Cumulocity. - App requests temperature and humidity to the Arduino. Finally, we add a slight delay of 20 ms using the delay() method to avoid overloading the system with continuous communication. Before uploading the code, you need to enter the MAC address of the other board (the board you’re sending data to). . status() != WL_CONNECTED) { delay(500); Serial. Upload the following code to each of your boards. The library supports DHT11, DHT22, and DHT21. php Arduino Sketch In our example, we use two different characteristics, TX and RX under the overarching "service" to send data to and receive data from a client (Android device) via these two channels. The ESP32 devices will send CSI data to target computer using mDNS to resolve IP address and UDP to deliver packets. I am thinking of using the Android app to download a new software image to the ESP32. I monitor numerous sensors and send data every 15 minutes.
