Device Firmware Upgrade from (Server Side to Client Side )

[patil_akash]

Hi Guys ,Currently i am working project related to Bluetooth Low Energy. I want to perform Device Firmware Upgrade from (Server Side  to  Client Side ) need some Sample code  in C language  to  perform  this task.

I have seen one code related with this but its in Android . I am unable to know the flow of execution for particular ( https://github.com/NordicSemiconductor/Android-DFU-Library) . I need this code in c language . Is there any tool that covert this code to c , where I can understand the flow.

Please help me out .I will be  thankful

Hi,

You can find some un-official DFU controller implementations attached at the end of this tutorial: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader.

Could you precise the reference you want to show us ?

I think he want c code example to use DFU from master side over BLE.

See section 6 in the appendix: "DFU Master code". It's only for SPI and UART.
