title: ESP32 IDF Ble Gatt Server Example
body: <p>I am trying to use esp32 IoT development framework. It is a bit complicated for me especially BLE examples. I am trying to understand gatts_service_table example but it has huge code inside and too hard for the first BLE APP. Is there any simple Ble example on IDF? I know kolbans libraries and I tried that but my aim is IDF. But to learn IDF I have to improve my programming skills first.</p>
  <p>I want to create a profile. After add service inside, and characteristic. After creating my BLE architecture, send receive data with a phone app.</p>
