How to upgrade NRF52832 to DFU through UART.

[RDL_ZYL]

We currently have a project that requires downloading firmware through 4G and transmitting it to NRF52832 through serial port for DFU. Do you have any relevant routine code for me to refer to?

Hi,

Which SDK version are you using? 

What kind of device is doing the 4G and download of the firmware? The official tool from Nordic to perform serial DFU is nrfutil, which is a python-based command line tool.

You can find C-based Serial DFU Master code example developed by my colleague in this tutorial.

Best regards,
Jørgen

I am using SDK 15.2, and I will take a look at this tutorial now. Thanks.

As you can see, the code in the tutorial requires version 8.15.0 of FamilyPack, but I cannot find this version on the official website. Do you have it.
