[PATCH BlueZ] mesh: Implement AddAppKey and AddNetKey methods

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

 



This adds implementation for the following methods on
org.bluez.mesh.Node1 interface:
void AddNetKey(object element_path, uint16 destination,
		uint16 subnet_index, uint16 net_index, boolean update)
void AddAppKey(object element_path, uint16 destination,
		uint16 app_index, uint16 net_index, boolean update)
