nrf52832 sdk15.2.0 dfu support BLE, UART, but I want to add other wireless dfu method, how to add ? related documents？

Hi,

The bootloader has a modular design to make it easier to integrate custom transport layers. The requirements for this is outlined in the documentation here: transport layers. You can also find an architectural overview of the bootloader implementation here.

so if not have some related document for what code needs to be modified ？

[Vidar Berg]

You will need to create a new transport that adds support for the wireless protocol you wish to use, I don't think it would make sense to modify one of the existing transports.

yeah, I understand the modular design, but I don't know the the common interface, what code need be replaced?

[Vidar Berg]

I've update the "transport layer" to point the correct chapter. This explains the interface which the transport need to use.

sdk13.0.0 dfu protocol is the same with sdk15.2.0 ?

[Vidar Berg]

There have been made some improvements to the bootloader since then, but the protocol is the same. You should refer to the SDK 13 documentation.

thanks
