RE: Not able to read IKEA Trådfri bulb with nRF ZigBee

Hi,
If you want to get a better context on what's going on in the network, but do not have a Zigbee sniffer around/other DK, you may enable logging in the CLI example through the following command:

log enable info

Now you should be able to see the log message, indicating that the bulb has joined the CLI's network.

Afterwards, there is a set of commands to query/discover the device's capabilities:

zdo match_desc
zdo simple_desc_req
zdo active_ep

If you do not see the successful association inside logs, there is no other way around - you will need a sniffer and paste the traffic dump here.

If everything works, but the device does not respond to the match descriptor request (both profile IDs), try using a different broadcast address (0xFFFD). I've seen devices, that did not respond to the 0xFFFF (all devices), but replied to the 0xFFFD (routers-only).

Side note: in the default configuration every reset of the CLI example erases the network data. As a result, you have to modify the example by changing the ERASE_PERSISTENT_CONFIG setting or factory reset all devices with every CLI reboot.

Best regards,
Tomchy

Hi,

The IKEA Trådfri uses the Home Automation (0x0104) profile, and not Zigbee Light Link. Could you try to use 0x0104 instead of 0xc05e with the zdo match_desc command and see if that solves your problem?

If you're still having problems, could you please capture a sniffer log? You can see how to do this here.

Best regards,

Marte
