Mesh DFU and provisioning data

[Thomas-Brilliant]

Will Mesh DFU overwrite the mesh provisioning data on my device? Let's say I have a device that has been provisioned for my mesh network. If I issue Mesh DFU for the Bootloader, SoftDevice, and Application for that device, will it rejoin my mesh network when it boots into the firmware?

Hi. 

will it rejoin my mesh network when it boots into the firmware?

Yes, after the DFU your device will join the the same network it was provisioned to before the DFU. So there is no need to re-provision devices after performing DFU. 

Best regards, 
Joakim.
