6.5 Touchlink Commissioning
The Zigbee protocol provides special commissioning called
Touchlink, which is an easy-to-use proximity mechanism for
commissioning a device to a network. The Touchlink commissioning
cluster provides commands to support Touchlink commissioning. The
Touchlink commissioning command set has command identifiers in the
range 0x00-0x3f and is transmitted using the inter-PAN transmission service. This
process works by the Touchlink initiator determining the proximity of
the target device (to be commissioned) and negotiating/transferring network parameters.
The Touchlink commissioning process can be used to form a new network
or to join a node to an existing network. Touchlink is initiated on a
node called the initiator. The ZCL provides the Touchlink as a cluster.
The initiator must support the Touchlink cluster as a client, and the
target node must support the cluster as a server. If it is required on a node, enable
Touchlink commissioning via the Zigbee base device attribute bdbCommissioningMode. For more
details on Touchlink commissioning, refer to the ZigBee Alliance
Cluster Library Specification Revision 8 (075123).
ColorSceneController, which is an end device type, brings
the light into the network by requesting the light to form the distributed network via
Touchlink. To enable Touchlink commissioning,
bring a color scene controller close to a target (light) device around like 20-30 cms
range.
