Buttonless DFU Example broken

parco

Hi there,

I know you guys are very busy and I appreciate your quick response on Devzone.

I'd like to make a request for a more polished example of Buttonless DFU using SDK 12.1 with nRF52.

We are nearing production and if there's anything I'd like to get in concrete, it's a reliable way to upgrade firmware in the field.

The current example is not working out of the box, and the documentation doesn't offer a complete start to finish of how to upgrade. For example, what should we do after we send a 0x01 to the characteristic?

Thanks, Paul

    Hi Paul,

    I guess you got part of the answer from here already.

    What is exactly the issue you are having ?

    After you send 0x01 to the characteristic, would it switch to the DFU bootloader ? Have you done any test with the DFU bootloader to update a new firmware ?

    Note that bonding information is not forward from the application to the bootloader in the current bootloader and experimental buttonless application.

    There are some bug fixes in the current experimental buttonless application, please use this version made by my colleague, Vidar. nRF5_SDK_12.1.0_buttonless_dfu.zip

    @Hung: Maybe you misunderstood my previous comment; I have used the experimental_ble_app_buttonless_dfu project, modified by Vidar in the zip file link above. It does not go to the DFU mode as mentioned by daniel77 and me above. "With my iPhone, I see the same as Daniel77; Nordic_Template and the services he mentioned. When I use Master Control Panel from my computer I see "Nordic_Template" with a write/notify Characteristic. I write 01 00 to the value and rescan, but the Board does not go to bootloader."
