nRF52840 over the air firmware/software update

[Pranav Sanghadia]

Does nRF52840 support over air firmware/software update? Is there any white paper or app note available?

[SRA]

Yes, the same DFU bootloader from the SDK that the other chips can use. Part of the SDK

You can find the bootloader example for the nRF52840 DK(PCA10056) in the examples\dfu\bootloader_secure\pca10056 in the SDK v13.0.0 Alpha release.

Hi Bjørn Spockeli

I couldn't program the bootloader code to nRF52840DK use nRFgo, it always said: "Verification failed". did you saw this problem before?

[JG]

Is there a DUG in the nRFgo ? it's couldn't down load the bootloader to nRF52840?
