DFU with HCI/UART to apply Embedded linux system

[Ryan Huang]

Hi,

I can use nRFgo Studio via nRF5x Bootloader to update application firmware(Hex file).

It look to be using "nrfutil.exe" to create a XXX.zip file and go through UART to update application firmware.

If I want using like to the "nrfutil.exe" program to apply in our embedded linux system, let our linux system can use the nrfutil tool(command) via UART to update the firmware of nRF5x chip.

Does anyone tell me how can I develop it ?

Thanks

Ryan

@Ryan: We provided github.com/.../pc-nrfutil nrfutil source. I haven't tried myself to compile it on Linux but there are many customers already did.

Hi Hung Bui, Thanks for your reply!

The nrfutil source is a Python package. Do you have the C source or example to develop the DFU client use serial (HCI) transport to send Device Firmware Updates?

[Hung Bui]

I'm afraid we don't. You may want to base on what we have in Python and port that to C.

Hi Hung Bui, Thanks for your reply! May you develop a C sample code about Serial (HCI) packet format ?
