Router keeps leaving the network after joining (Zigbee)

[Amelie_grjn]

Hello,

We are using the nRF52840 dongle (PCA10059) with the CLI agent software  as a Zigbee network coordinator, and the Digi's XBEE S2C as a Router.

We are using XCTU to configure the S2C. But we are having the same issue. The router will be commissioned and then leave the network shortly after.

We also flashed another dongle with the nRF sniffer, but we are not able to locate where the error might come from. We spent the few last days on this issue whithout any promising results.

We would gladly appreciate any tips on that matter.

Thanks in advance.

Hi,

Could you please upload the sniffer log as a pcap file?

What happens if you try to use the command "bdb legacy enable" after starting the commissioning process with "bdb start"? This will enable legacy device support.

Best regards,

Marte

Thank you very much ! "bdb legacy enable" worked for us.

While we are here, I still have a question left, we are not able to print the data we sent from the router to te coordinator on the serial terminal (putty). Is there a way to do such a thing ?

Best regards,

Amélie

Hi Amélie,

I am glad to hear that!

Yes, you should be able to print the data. How to do this depends on what sort of command is sent from the router to the coordinator. When a Zigbee device in our SDK receives commands, they are mostly handled internally by the stack. However, in the CLI agent example there are multiple handlers and callbacks that override this internal handling, in order to do something else, or to perform additional actions, when receiving a command. You can use this to handle the received command as you want, and to print the data from the command. Do you have information about what kind of commands you are sending, that you want to print the data from?

Best regards,
