Add secured OTA in ble_app_template

[Muqarrab]

Hi,

I want to add a secured OTA(Button Less) in ble_peripheral\ble_app_template.

Is there any proper tutorial/document/example for this?

Thanks!

Hi,

Please consider using our Buttonless DFU Template Application as a starting point. You can also find more documentation about the buttonless mechanism here: Buttonless Secure DFU Service

Best regards,

Vidar

Hi,

The bootloader for 52840 has HW accelerated crypto enabled by default (cc310), are you sure you want to replace that with oberon?

[Muqarrab]

Hi,
I am just following the step if it is not necessary should I skip and not enable this?

[Vidar Berg]

Yes, I recommend you skip this step. You get a smaller flash footprint with the CC310 plus better perfomance.

Hi,

1-I am trying to upload Bottonless DFU and getting the following Error.

C:\Nordic\SDK\nRF5SDK17009d13099\nRF5_SDK_17.0.0_9d13099\examples\ble_peripheral\ble_app_buttonless_dfu\pca10056\s140\ses

2-How can I add butonless secure DFU service in my application?

[Vidar Berg]

Hi,

As you can see from the debug log, the error occurs because there is no bootloader present in flash. This is the same error you reported earlier. You can ignore this error for now by commenting the error check for your ble_dfu_buttonless_async_svci_init() calll in main().

Thanks Vidar Berg,

How can I add buttonless secure DFU service in my application? I am following the mentioned link but getting confused about how to add sevice? Any suggestion please 

[Vidar Berg]

Did you try to copy the buttonless service initialisation from the template example as I suggested, and in that case, did you encounter any errors?
