Configuring server setup

The nRF Connect Bluetooth® Low Energy app supports the configuration of the local device's GATT (Generic Attribute profile) attribute table, also known as server setup. Adding attributes to the server setup allows the local device to exchange data with a connected peer device.

   Initially, the default server setup that is displayed contains only GAP and GATT services.

2. Click New service.
3. Select the service you just added.
   A form is displayed.
4. Define the attribute values, then click Save.
5. To add a new characteristic, expand the added New Service, then click New characteristic.
6. Select the characteristic you just added.
   A form is displayed.
7. Define the attribute values, then click Save.
   Note: When adding a notify or indicate property on a characteristic, you need to add a Client Characteristic Configuration Descriptor (CCCD) for that characteristic.
8. To add a new descriptor, expand the added New Characteristic, then click New descriptor.
9. Select the descriptor you just added.
   A form is displayed.
10. Define the attribute values, then click Save.
11. When you have completed the server setup, click Apply to device to upload the setup to the local device.
