ESP32 minimal BLE Device Information Service (DIS) example

This example demonstrates how to implement a minimal BLE Device Information Service (DIS) on the ESP32 using the ESP-IDF framework and the espressif/ble_services component.

Prerequisites

Add the following managed components to your project:

example.sh

idf.py add-dependency "espressif/ble_services^1.0.0"
idf.py add-dependency "espressif/ble_conn_mgr:^1.0.0"

idf.py add-dependency "espressif/ble_services^1.0.0"
idf.py add-dependency "espressif/ble_conn_mgr:^1.0.0"

Also, you need to configure the following options in your sdkconfig (or use idf.py menuconfig):

`main.cpp`

In main.c or main.cpp, include the BLE header file:

example.cpp

#include "BLE.hpp"

#include "BLE.hpp"

In the app_main() function, you need to add

example.cpp

ESP_ERROR_CHECK(esp_event_loop_create_default());

ESP_ERROR_CHECK(esp_event_loop_create_default());

to the beginning of the function, unless you already create an event loop!

Only after creating the event loop, you can call InitBLE() to initialize the BLE stack and start advertising.
