is #BluetoothMesh provisioning required after firmware upgrade over DFU ?

[vikrant8051]

In latest release of MESH SDK v1.0.0, there is support for DFU Bootloader.

It will be helpful, when there is upgrade from firmware side to add new features & remove bugs if any.

Will Firmware upgrade, erase #BluetoothMesh provisioning & configuration details from flash memory ?

If yes, then we have to re-provision & configure every device & I want to avoid this.

Thank You !!

The firmware update should preserve the provisioning data stored on the Flash, so it should be possible to update the device firmware and use the provisioning data stored from earlier.

Who should preserve the provisioning data ? Means is MESH SDK automatically take care of that or will it be responsibility of embedded application developer ?
