In order for your device to act as a peripheral, first you need to open a BluetoothGattServer and populate it with at least one BluetoothGattService and one BluetoothGattCharacteristic: For example: GATT server is a device that can measure Heart Rate and GATT client request Heart Rate data and send it to a server so that the doctor can monitor patients remotely. In order to make this demo we will use 2 ESP32s and Demo 26. The GATT Service Application is an example that implements the GATT service using the hardware delivered in the nRF5 Development Kit. This application is used to showcase the Service Changed Characteristic (0x2A05). The application uses a button to send Service Changed indications to connected peers.
