Hi,
Assuming that you are yousing Z-stack, you should enable fragmentation option
in Z-stack to be able to send more then 99 bytes of data (99 is the default max
application payload allowed)
Secondly, I would like to recommend you to post any ZigBee related question on the
Low Power RF ZigBee® Software & IEEE 802.15.4 Forum

How can I enable fragmentation option?
Thanks!
What is the version of Z-stack you are using?
