NORDIC DFU UPDATE

[lucaross]

Hi ,

I need to update the NRF52832 with another different module.

I can update without problem by using the nrf connect app.

I would like to use another device without using the app ; but to do this I need to port your code inside the device.

Is there a C library or something ?

Hi ,

thanks for your answer.

My problem is not how to generate the DFU packet.

I use your tools ( nrfutill ecc..) and I have the zip.

My problem is to send the zip packet to the NRF52832.

What Have I to do after the BLE connection ? 

Is there a characteristic or profile that I can use ? Or It is a normal sendind directly to the internal flash maybe passing the flash address..

HI ,

I did the example on the nRFutil 3.5 with SDK 14.2 (https://github.com/jimmywong2003/nrf-slim-serial-uart-dfu-host-c-code).  You can have a reference.
