TABLE 3-7: ZigBee™ PROTOCOL APS CONFIGURATION SELECTION

TABLE 3-8: ZIGBEE™ PROTOCOL APS GROUP ADDRESSING SELECTION

Configuration Option Description

Max Frames From APL Layer Each frame sent down from the Application layer must be buffered for retransmission

on failure and for reporting back transmission confirmation status. Enter the number

of frames that can be in the process of transmitting at the same time.

Max APS ACK Frames

Generated

If messages are received from other nodes with APS level Acknowledgement

requested, the APS layer will automatically transmit the Acknowledge; however,

space is still required in the confirmation queue. Enter the number of APS level

Acknowledges your application is expected to be in the process of transmitting at the

same time.

Max APS Addresses ZigBee™ protocol allows the Application layer to specify a message destination

using a node’s 64-bit MAC address, rather than the 16-bit network address. If a

64-bit MAC address is specified, the APS layer searches an application maintained

table for the corresponding 16-bit network address. Enter the size of that table in this

field. If security is being used, regardless of device type or functionality, the value

must be non-zero. If security is not being used and either the Application layer will

use only 16-bit network addresses to send messages, or the application is an IEEE

Reduced Function Device, the value may be zero. This address map is mandatory if

security is supported. It must be large enough to contain one entry for each device

that the application will communicate with.

Binding Support If the device will support bindings, select this option and enter the “Binding Table

Size”. If a device supports bindings, it must be able to buffer all incoming indirect

messages for retransmission. Enter the number of indirect messages the application

is expected to handle concurrently in the “Max Buffered Indirect Messages” edit box.

Configuration Option Description

Max Groups

If multicasting is supported, then the device can be a member of multiple groups.

Enter the maximum number of groups that this device can be a member of.

Maximum Group Endpoints If multicasting is supported, then for each individual group that the device is a mem-

ber of, the ZigBee™ protocol allows the application layer to specify a list of endpoints

that are associated with each group identifier, i.e. GroupID. Messages that are send

using multicasting will be sent to all the endpoints associated with the group identifier

that is used in the message's address. Enter the maximum number of endpoints that

can be associated with a group identifier.

Group Processing Buffers If multicasting is supported, then internal to the Microchip Stack are buffers that hold

each group addressed message which subsequently will be directed to the associ-

ated endpoints. Enter the maximum number of messages that can be simultaneously

buffered up, awaiting processing before they are sent to the appropriate endpoint.
