Power down feature of the BLE Mesh

Question

Hi, There. I am preparing to program a Mesh application based on nrf52840. The application supports the recovery from the points of power off. 
 So, I have a question. It will storage all info on the power-off point? ANd it will resume from the point, like intermittent computing?

Hi, 
 All our examples can recover from a power reset. Except if you select PERSISTENT_STORAGE = 0.

It stores everything, netkey, devkey, appkey, IV Index. The sequence number is stored in a block. The reason is that if we store the sequence number every time it changes, it will wear out the flash, so we store the sequence number in the block, everytime you booting up, you use the next block.

It will storage all info on the power-off point? 
 What do you mean by the "power-off point"? Is it as I mentioned above we can recover from a power reset, soft reset, etc?
