It allows you to exchange data with a device running the ESP32 ble_spp_server example. The ESP32 microcontroller transmits sensor data to the client device and receives control commands from the client. For example, if the ESP32 Client does not enable BLE SPP first, then it should enable listening with command AT+BLEGATTCWR=0,3,7,1,1 first for the ESP32 Server to transmit successfully. We’ll show you how to advertise services and change the value of characteristics and how to detect if another BLE device wrote on the ESP32 characteristics. It’s important to note that the GATT roles of client and server are independent from the GAP roles of peripheral and central. In this guide, we’ll provide you with all the information to master Bluetooth (Classic and Low Energy) with the ESP32 in no time. These devices are everywhere these days. 8 posts • Page 1 of 1.
