Not sure what is the max size of mac payload. The mac payload length is defined by MAC_MAX_FRAME_SIZE in f8wconfig.cfg and you can try to change it.

Hi sudha,

Zigbee specification determines a maximum MAC payload size of 128 bytes, I recommend you refer to Section 9.9 of the Z-Stack 3.0 Developer's Guide to understand how fragmentation is performed inside the stack.

Ryan
