Dear developers,
My device uses the NRF52840 SoC and is equipped with a modem for internet access.
To perform firmware upgrade, I imagine I would have to download a DFU image from a secure location, somehow put the device in DFU mode, and then perform the update. I've never done something like this before and I'm not sure how to start.
I am well familiar with performing DFU over BLE.
Are there any examples/tutorials that can get me started?
Thanks
Tim
