Selective DFU over mesh

[shohidur]

Hi,

I have managed to run DFU mesh example and successfully updated firmware of whole mesh network. Now i am looking for options to perform customized DFU over mesh. Lets say a group of devices or a specific device.

Is it possible ? If so please suggest me a way to attain this.

Thanks

Hi, 

To customize an DFU update to a group of nodes, for now we can only select by using application_id. 
This is the application_id in the bootloader_config .json file you used when you create the device page hex file. 

Different nodes in your setup can have different application id, for example light switch can have application id 2 when light bulb can have application id 3. 

When you want to update only light blubs, you generate DFU .zip package with the application_id = 3. 

This solution, however, doesn't support grouping, for example it wouldn't cover the case where you only want to update light bulbs on 3rd floor for example.
