Backup and Restore Coordinator (TZ-1172)

[mw75]

Question

Please describe the process and required tools to backup an ESP32-C6 Coordinator in an way, that allows restore to an equivalent hardware without the need of repairing all devices and with persistent short addresses. Is a "service PC" required to backup, or is it possible to collect all required information right on the ESP and write it to a connected SD-Card?

Thanks and regards,
Mario Wolff

Please check if the solution discussed in #289 satisfies your requirements.

Hi @lpy4105
thanks for your hint regarding an already existing question with already two different solutions! The only missing part is the corresponding process step to dump zb_storage. Is it save to use "ZDO Device Authorized (0x2f)" for this?

Is NVS also used by the ZigBee-SDK as it is initialized in all examples i could find? Is the content of zb_fct volatile as it is not recommended to backup it the referenced issue?

Thanks again!
