nrf52840 soc bootloader

[Gourav]

Hello,

I have a following requirements,

Build a custom bootloader which accepts DFU through OTA and UART.

this boot loader must also contain softdevice , so that finally there is only one hex file. Using this hex file DFU can be done through OTA and UART.

Are there any examples do so???

Regards,

Gourav

Hello,

I'd recommend you to read this blog post to get an overview of our DFU implementation if you haven't done it already: https://devzone.nordicsemi.com/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader 

We don't have an example that combines both BLE and UART, but it's possible. You can select one of the bootloaders, then add another transport layer.
