My current project has DFU enabled through the secure BLE bootloader and it works well. I would like to include the additional option of performing DFU over USB. Is it possible to combine the two functions into the same bootloader? Does Nordic have any sample code which does this?
Thanks
Hi
It is possible to do, yes, but there is no example showing how to do it unfortunately.
How are you planning to switch between the two bootloader transports?
Best regards
Torbjørn
I have a similar requirement to use USB DFU in the factory, use background DFU over BLE in the field. Is there any pointer to achieve this?
I read that for background DFU, the Bootloader shouldn't initialize any of the transports however, I have the need to have these be initialized and then choose between a factory/RMA update vs. user/field update.
Appreciate any help.
Thanks and regards,
Ananth
Hi Ananth,
We are still working on it. We do have a working prototype on SDK v14.1 that I attached here. You can have a look.
Hi Hung Bui,
Do you have a working example for the S132 15.1 SDK the bootloader_secure_ble_serial.zip won't compile on the 15.1 SDK? and I would like to use the S132 6.0.0 SD
Hi guys,
Sorry for long delay.
I have a prototype that works. This is not an official version it has some quick dirty fix. We will try to release an update later on.
Please try and let me know if it works for you (SDK v15.2 , you need to generate your own public_key.c )
Thanks Hung Bui,
I'll give this a shot. Will this be a minor update to the SDK when we have the real fix in a release?
Hi sorry it was not with all the fixed. Please use this new version.

Hi Hung Bui,
I was also looking for similar functionality DFU over ble and uart for nrf52840 could you post an example for pca10056. I have also tried to look into this pca10040_ble_uart_debug_SDK15_2.zip. but this dosen't compile and shows error as nrf_log_backend_rtt.c: No such file or directory
Thanks and Regards

I ran into this problem while trying this out, it's because the paths are all messed up. You just need to either redo all the paths or copy the pca10040_ble_uart_debug folder into <whatever path you have before this>\nRF5_SDK_15.2.0\examples\dfu\secure_bootloader and then it will build.
Hello Hung Bui,
I got it running on the nRF52832 with SDK15.3 as Non-Debug version but I am wondering if it might be possible to get this Non-Debug version fit into the 24kB Flash which is resevred for the bootloader. Is there any known overhead regarding used drivers or something else which I could try to remove to save flash memory? If you could give me a hint it would be great.
Thank you
Peter
Hi Peter,
Please create a new case for your question. But I don't think there is anything you can remove to save more space except for increasing the optimization level.
Hi Peter
Can you share with us your nRF52832 with SDK15.3 as Non-Debug code
Thanks
