CC2652R: ZED device stopped working suddenly

Part Number: CC2652R
Other Parts Discussed in Thread: Z-STACK

Hi!

I use 3 CC2652R chips to formate a network,one works in ZC,and 2 work in ZED.All 3 work in ZNP mode.

I need to transfer a lot of data from 2 ZEDs to ZC, one ZED transmits about 13K of data to ZC at a time.

I used API:afDataRequest in file mtAf.c to transmit data,one package's payload size is 82 bytes,and 13k data need to transfer 164 times.

 An exception occurred during data transmission,please refer to the screenshot of the sniffer log as shown in fig1.

ZED(0xd94b) transmited data at first,but stopped after transmited several bags(at No.68204),and also ZED(0xd94b) stopped to send "56 Data Request",the polling between ZED(0xd94b) and ZC became abnormal.ZED(0xd94b) seemed to be dead.ZED(0x38bc) was normal.

After that,ZC broadcasted "Discover Route" again and again as shown in fig2.

The connection between ZED(0xd94b) and ZC cannot be recovered.

I want to know why ZED(0xd94b) died suddenly while transmitting data.How to solve this large data transmit problem?

I provide sniffer log file.

Z-Stack I used is 4.10.00,and sdk is simplelink_cc13x2_26x2_sdk_4_10_00_78.

Wireshark version is 3.0.0.

This problem is rather urgent,I'm looking forward to your reply!

Thank you very much!
