Hi Kawing,

Currently we only have solution to do BLE DFU from either a PC or a mobile phone, but don't have an example to do DFU from a nRF52.

I can see that there is a quite a few request for this I will report this internally and hopefully will have an example in the near future. 

For now I would suggest to have a look at our DFU library in our nRF Connect /nRF Toolbox app on Android/iOS and on PC. 

We do have example for DFU master running on NRF52 with UART and SPI that you may want to have a look, here.
