bt_gatt_server_start()

Description

Registers all created GATT services and makes them visible.

Bluetooth advertising must be set up for the device to start advertising as connectable. Refer to the GATT server guide for more information.

In the event that the GATT server attributes have been altered and a GATT client device was either previously connected or connected prior to the registration of all services, it may be necessary for the client to perform a service rediscovery to access the updated GATT server attributes.

Syntax

bt_gatt_server_start();

Parameters

This function has no parameters.

Returns

Return value	Return explanation
SCRIPT_OPERATION_SUCCESS	Successfully registered all services.
SCRIPT_OPERATION_FAILED	Failed to register one or more services.
