[PATCH BlueZ v1 1/1] Add Support for BLE Services to Adapter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds support for adding primary service UUIDs
to adapter's list. These uuids can then be sent to upper
layers using the DBUS method of get_properties and signal
adapter_emit_uuids_updated.
