Fragment sending is not working in Z-stack 3.0.2

Aries Lord

Part Number: CC2530
Other Parts Discussed in Thread: CC2652P,

I have tried on Router-Pro.lib and EndDevice-Pro.lib

When CC2530 send a AF-packet which is longer than 83-byte to CC2652P, it could not send any data, and AF-DATA-Confirm gives "0xE9" status.

Hi Aries,

Are you able to replicate this behavior with default examples provided by TI? Can you please ensure that ZIGBEE_FRAGMENTATION is set and that APSF_DEFAULT_WINDOW_SIZE and APSF_DEFAULT_INTERFRAME_DELAY are correctly defined in ZGlobals.h? Do you see any packets from the fragmented message sent out over-the-air? 0xE9 is ZMacNoAck meaning the APS ACK is not received from the destination.

Regards,
Ryan

I have not seen any fragmented message sent out over-the-air on sniffer tool. But if "AF_EN_SECURITY" is enabled when send, the fragmented message can be sent out.

Thanks for providing this update. Does this workaround resolve your issue?

If coordinate can't support R21, the Fragment sending will not work.
