Hello,

As Gaurav says, particularly the first link is useful for getting started with DFU. 

Do you intend to use Mesh DFU or "Normal" BLE DFU? The difference is that the Mesh DFU can update several Mesh nodes at once in the background while the old application is running. However, the DFU is significantly slower than BLE DFU. A Mesh DFU can take 30-60 minutes, while a BLE DFU can take everything from 20 seconds to one minute. 

So the mesh DFU is intended for networks where you want to update hundreds of nodes at once.

Either way, I can recommend going through the getting-started-with-nordics-secure-dfu-bootloader guide, as an intro to bootloaders.

If you later want to check out the Mesh bootloader, please check out the Mesh DFU guide.

Best regards,

Edvin
