Technical requirements
In all examples, we only use a single devkit. In the BLE Mesh networking example, however, you can add more nodes in the network by flashing several devkits with different firmware where you can try different BLE parameters.
On the software side, we will use the nRF Connect and nRF Mesh mobile applications from Nordic Semiconductor. The applications are freely available for both Android and iOS platforms.
You can find the example code in the GitHub repository here: https://github.com/PacktPublishing/Internet-of-Things-with-ESP32/tree/main/ch8.
