27 ProBee-ZS10 User Guide Rev.1.5
• Configure the ZS10 node type as an end-device
• Optionally, select the channel mask. Otherwise, the ZS10 will use the default channel mask.
• Optionally, set up the PAN ID and/or the extended PAN ID. Otherwise, the ZS10 will scan and join
the ZigBee network found automatically.
• Configure the poll timeout and the poll period
Please refer to the section 3.2 Setting up ZS10 as a Router for the AT commands regarding the node
type selection, the channel mask configuration and the PAN ID/Extended PAN ID configuration.
When an end-device joins the network, the power LED blinks periodically. The end-device belongs to a
parent node which is either the coordinator or a router, and the parent node registers the end-device to its
internal child table for message relaying. This table is maintained as long as the end-device polls the
parent node periodically within the poll timeout value of the parent node. If the end-device does not poll
for the poll timeout value of the parent node, the parent node removes the end-device from its child table
and does not relay the message any more. Hence, the poll period of the end-device should be equal or
shorter than the poll timeout of the parent node to avoid accidental removal of the end-device from the
parent node’s child table.
The ZS10 poll interval can be configured by setting the S-registers using the AT commands as below.
ATS51=n, where n is poll timeout in seconds and the default is 60.
This value is for a parent node. If an end-device does not send a poll request to its parent coordinator or
router within the poll timeout, the end-device is removed from the child table.
ATS56=n, where n is poll period in seconds and the default is 5.
End-device polls the parent node at poll period defined by S56 periodically. It is for the connection to the
parent node and data transmission with other nodes in the network.
ATS55=n, where n is rejoin timeout and the default is 10.
When the connection to the parent node is broken for S55 in seconds, the child node tries to rejoin the
current network.
Even though the end-device needs to poll the parent node continuously, it does not go into the sleep
mode and it can send and receive messages any time unlike the sleepy end-device.
3.4 Setting up ZS10 as a Sleepy End-Device
A sleepy end-device can turn off radio to save power. To configure the ZS10 as a ZigBee sleepy end-
device, please follow the steps below.
