DFU controller in central nRF52 device

[Robin]

Hi Nordic team,

Is there any sample project which implements DFU controller in nRF52832 central device? I need to update peripheral device firmware from central device by using DFU. In my another project, I was able to implement DFU target in peri device and succeeded firmware update from android app using SDK. So, I can say DFU target is ready. I just need DFU controller in centeral device.

Please advise any sample project which can help my developement of DFU controller.

Thansk,

Robin

Hi,

Sorry for the delay. We do not have any official DFU master implementation for the nRF5 SDK DFU protocol, so the closest you get is probably the code yu1998 linked to. Other than that we have DFU master implementations in python, JS, and for iOS and Android you can use as reference. Bu unfortunately nothing for the nRF. So you would have to implement that yourself, potentially using some of the existing implementations as reference, as well as referring to the DFU protocol documentation.
