Tool/software:

Issue: A Client (CC2531 Dongle device) auto disconnect to Coordinator (CC2530F256 device) after connected for a while
Would you please tell me how to fix the auto disconnect issue

1. CC2530F256 device :

- use TI Z-Stack 3.0.1 software,

- configure a Device as a Coordinator

2. CC2531 Dongle device:

- run Simulator software

- configure a device as a Client

After starting Simulator, it connects successful to a Coordinator

A Client connects for a while then a Client (CC2531 Dongle device) disconnects by itself

Thanks

Hi oanh,

We would need a sniffer log of the over-the-air packets and information about the Z-Stack 3.0.1 firmware configuration to know more about what occurred. Does the dongle device disconnect occasionally or always, and does it always occur around the same time after joining? How long does it take to disconnect? Are there any other devices in the network, and if so then how many?

If the dongle device is using a legacy Zigbee Specification (ex. HA 1.2) then you will need to make sure that BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE is set to FALSE as the TCLK exchange is only a Zigbee 3.0 feature.

Regards,
Ryan

Device always disconnects after connecting for a while (couple minutes), It takes random time (minutes) to disconnect after connects. in the logs I see there are other devices (2 devices).
would you please let me know how to verify the dongle device is using a legacy Zigbee Specification (ex. HA 1.2) ?
thanks

It looks like the ZC is sending a leave and disconnecting in less than 10 seconds from the dongle device attempting to join (value of BDBC_TC_LINK_KEY_EXANGE_TIMEOUT by default is 5000 ms).

You're going to know it's a HA 1.2 device by it not initiating a TCLK exchange procedure(there should be APS packets representing this immediately after the ZC sends the network key upon association).

You really should be using Packet Sniffer 2 and Wireshark to sniff Zigbee 3.0 packets.

Regards,
Ryan

Thank you so much for your help
I update code to
#define BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE FALSE

Verify the change with sniffer, Still have the auto Disconnect issue

attached is sniffer log
Coord-disconnect4-TC_REQUIRE_KEY_EXCHANGE-False-.psd

Would you please tell me where can I get Packed Sniffer 2?

Thanks
