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

, where xxx

xxx is EPID to use. For example, 0123456789ABCDEF. Default setting is 000

000.

3.1.4

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:

AT+PERMIT=255 or AT+PJ=255
