3.4.4 PAN ID Configuration for Coordinator
Every ZigBee network should be assigned a PAN ID to identify the network. If the PAN ID is 0000, the
ZE20S will generate a random 16-bit PAN ID to start the ZigBee network. Otherwise, the user can enter
the PAN ID using the AT command as below:
AT+PANID=xxxx or AT+PI=xxxx
, where xxxx is PAN ID to use. For example, 12AB. Default setting is 0000
When choosing a PAN ID, the user needs to make sure that there is no ZigBee network using the same
PAN ID. If the PAN ID is already used by another ZigBee network, the PAN ID is unavailable and the user
should choose a new PAN ID. In order to avoid this, PAN ID auto-generation is strongly recommended.
The user can also assign the 64-bit extended PAN ID to the ZE20S using the AT command below. If the
extended PAN ID is 0000000000000000, the ZE20S uses its IEEE address as the extended PAN ID. The
extended PAN ID cannot be shared with other ZigBee networks, either.
AT+EPID=xxx
…
xxx or AT+EI= xxx
…
xxx
, where xxx
…
xxx is EPID to use. For example, 0123456789ABCDEF. Default setting is 000

000.
3.4.5 Permit Joining
When a router or an end-device tries to join the ZigBee network, there should be at least one coordinator
or router which is permitting joining. If there is no router in the ZigBee network yet, the coordinator should
permit joining. The ZE20S provides three ways to permit joining are as follows:
Permanently permitting by configuration
Transiently permitting by AT command
Transiently permitting by digital input signal
If joining is permanently permitted, any device can join anytime. Since this will allow even an unidentified
device to join the network anytime, this mode should be selected with extra caution. The AT command to
permit joining permanently is as follows:
