How do I replace the NRFUTIL tool on DFU (USB)

[stars]

Hi,

When using USB to upgrade, it is necessary to use NRFUtil tool to transfer the upgrade package, may I ask what download protocol it includes? Our requirement is to make a tool like NRFUtil by ourselves, instead of using NRFUtil for upgrade, would you like to know what protocol it uses for transmission?Using the Windows platform.

Best regards,Stars

Hi

nRFUtil is a Python package. It has command-line utility that supports DFU and cryptographic functionalities.You can also see the nRF Util page in our Infocenter with the complete User Guide here.

Best regards,
