In nRF5 SDK for mesh v5.0, information related to provisioning and communication stored in the internal flash memory

[ljw]

In nRF5 SDK for mesh v5.0, what kind of information (related to provisioing and communication) is stored in the internal flash memory?

And what is the API for accessing each information and the API for removing each information from the internal flash memory?

Hi, 

What type of device are you referring to? Is it the provisioner you are wondering about?

I mentioned about information stored in a client and a server.

Hi,

The device, application and network keys are stored on the client/server node.

Every device has a unique device key, which is only known to the provisioner and the device itself. The device key is used when configuring a device with new encryption keys (network or application keys).

Application keys are used to separate access rights to different applications in the network, while all devices sharing a network key are considered part of the network and may send and relay messages across it.

You can read more about this here.

Use dsm_appkey_get_all() and dsm_subnet_get_all() to read out AppKeys and NetKeys.

Use dsm_appkey_delete() and dsm_subnet_delete() to delete AppKeys and NetKeys.

Take a look at Application key management and Network key management for APIs regarding AppKey/NetKey.
