/**
 * @brief This example demonstrates simple Zigbee light bulb.
 *
 * The example demonstrates how to use Zigbee library to create a end device light bulb.
 * The light bulb is a Zigbee end device, which is controlled by a Zigbee coordinator.
 *
 * Proper Zigbee mode must be selected in Tools->Zigbee mode
 * and also the correct partition scheme must be selected in Tools->Partition Scheme.
 *
 * Please check the README.md for instructions and more detailed description.

Just tried again - this is the logging from Zigbee2MQTT.

(formatting was broken, I'd uploaded log file)

z2m.log

Hi @ScaredyCat, can you please use Verbose debug logging and also in Zigbee mode select your mode with the DEBUG option.
I done think there is anything broken in Zigbee library. The main issue I see is the Seeed Studio XIAO ESP32C6, you need to have a proper antenna setup. Do you use external one and do you set it up in your app correctly?

[P-R-O-C-H-Y]

Please refer to this comment: #10951 (comment)

Unfortuneately that's not the solution. The default is for this board to use the internal antenna and even forcing it to do so makes no difference.

I've also raised an issue with SeedStudio to see if they can help solve the problem.

I've tracked down the issue to the ConBee III stick I'm using for my Z2M integration. The latest firmware (0x26550900) fixes this issue. There's a web based flashing interface for users to update their ConBee III sticks as required you can find it here: https://phoscon.de/updater - it's a single html page so can be downloaded and used offline too.
