Routers leaving zigbee network after joining

[[email protected]]

Hi , I am using nrf52840 dk with zigbee cli example in sdk. I have configured nrf52840 as coordinator. I am using xbee pro s2c modules as router in zigbee network. Terminal shows the following message 

I am also sniffing the network and here is the result of wireshark sniffer 

I want to ask why cli is showing unimplemented signal 21 and why xbee device leaves after joining the network.

Hello,

Did you check what the unhandled signal was? The line "Unimplemented signal..." is printed in zigbee_helpers.c.

You can see that this is printed if you receive a signal that is not implemented in the switch.

21 is the ZB_NLME_STATUS_INDICATION defined in zboss_api_zdo.h on line 432-439 (line numbers from SDK4.0.0.

See the description of this event in that file.

As I said in your other ticket:
Exactly what the event does I am not sure. You must try to add this event to your event handler, and look at the parameters. Read the description for ZB_NLME_STATUS_INDICATION in zboss_api_zdo.h on line 432-439. Check out the zb_zdo_signal_nlme_status_indication_params_t struct in the same file.

Do you know why the devices choose to leave? Perhaps there is something in the datasheet of these devices saying something that you need to fulfill in order for them to stay in the network?

I was configuring wrong trust center link key on xbee devices . Issue resolved but thanks for your reply.
