Hello,

I ran this by our Zigbee team, and received the reply:

"I cannot find place of NVRAM code that may be corrupted by making this change, so I would say that this is safe to be changed between firmware upgrades."

So it should be fine to expand the number of child nodes via a DFU.

BR,

Edvin

I haven't experienced any issues. I wanted to ensure that there were no ZBOSS NVRAM allocation issues with updating this between versions.

Hello,

Do you experience any issues when updating the zb_set_max_children() from 10 to 15 after joining the network? I don't think you need to perform an actual DFU to check this. If it has joined a network, updating the FW without erasing the persistent storage area of the flash should behave the same as a DFU in this case, since the bootloader is on top, and the persistent storage is below that.

Best regards,

Edvin
