Does nRF52840 support over air firmware/software update? Is there any white paper or app note available?
Thanks very much for your reply. Could you please correct me if I understood wrong. To get OTA update for Application functional on nRF52840DK, the nRF5_SDK_15.3.0_59ac345\examples\dfu\open_bootloader example is a starting point. Am I right? The example consits of only main.c file, and updates images based on Bootloader and DFU modules?
shah_shah: Its only the Secure Bootloader that supports Bluetooth OTA, the Open Bootloader only supports the USB transport layer. I recommend that you follow the Testing section on how to use the example.
The Secure bootloader example only has a main.c file in the project folder, but it uses other source files from the SDK, i.e. SDK-folder\components\libraries\bootloader.

Hello Nihar_96, nRF team,
Were you able to perform an OTA update on nRF52840? I have a setup like a border router(NCP connected), other two nRF52840 DK, and I want to upgrade nRF52840s over BLE or over the mesh.
Is it possible?
Thanks,
Hardik
Hi Hardik,
If you want to perform OTA updates over BLE Mesh then yes this possible, please see the DFU example documentation in our nRF5 SDK for Mesh.
Best regards
Bjørn
