DFU Procedure for Mesh

[Mahesh kumar]

Hi,

I am using nRF52840 and Mesh SDK 5.0.0. I want to add a DFU feature in Mesh Light Switch Client and Server example code. I have generated zip files for the Client and Server(Followed same procedure as given for SDK's by combining secure boot loader and application through nrfutil). I have flashed the code to the devices for the first time through DFU on nRF connect app, but when i want to update the code through nRF connect app for the second time the DFU feature is not enabled.

I want to enable Mesh DFU in light switch client example to update the new application for the next time. I have gone through the document. Is there any code snippet to do the same or any other procedure for Mesh DFU. Please suggest me.

Thank you

Mahesh Kumar

Hi,

I have gone through the document.

What document have you gone through? 

From what you are describing above, it seems like you want to do DFU over BLE and not Mesh DFU. I might be wrong but you want to connect to a node and do DFU via nRF Connect app? I suggest you have a look at the Low Power node example and Configuring DFU over BLE using the LPN example. The example implements DFU over BLE for a mesh node.
