ESP32 Bluetooth Low Energy (BLE) on Arduino IDE | Random Nerd Tutorials
The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). This post is a quick introduction to BLE with the ESP32. First, we’ll explore what’s BLE and what it can be used for, and then we’ll take a look at some examples with the ESP32 using Arduino IDE. For a simple introduction we’ll create an ESP32 BLE server, and an ESP32 BLE scanner to find that server.
