Hi，
I am using nRF54L15-DK for Zigbee light_stwitch startup testing. After successfully connecting the development board to the Hub for the first time, I evaluated the time from booting up to reconnecting to the Hub by clicking the RESET button.
After adding the following configuration, the time delay from each boot to successful Zigbee reconnection is about 5 seconds (default configuration is about 1 second):
CONFIG_ZIGBEE_CHANNEL_SELECTION_MODE_MULTI=y
CONFIG_ZIGBEE_CHANNEL_MASK=0x3FE0000
Best Regards
