Microchip Information

14.2.3.2.4 Configuring fragmentation

The fragmentation feature allows to send larger amounts of data than it fits into a single frame, delegating all implementation details to the stack components. However, the maximum length of data that can be sent with one APS request is limited by the choice of certain CS parameters which are described in the list below:

CS_APS_MAX_BLOCKS_AMOUNT

Specifies the maximum amount of blocks to which request payload can be split.

CS_APS_BLOCK_SIZE

Specifies the size of a block. If the value is 0, then the maximum possible size is used.

CS_APS_MAX_TRANSMISSION_WINDOW_SIZE

The number of frames sent by the stack at once before waiting for acknowledgment. Once the delivery of these frames is acknowledged the next portion of frames is sent.
