Where is the bootloader hex?

[la-ble]

I'm getting started trying to use the device firmware update (DFU) feature of an nRF51822. I'm using soft-device (bluetooth abstraction) version S110-SD-v7.1.0, and SDK (API's to use that soft-device) version nRF-SDK-v6.1.0.

I'm trying to program in the bootloader to begin playing around with this feature using nRFgo Studio but have no idea where to download or find the compiled hex file. Also if there's a good starting point, please let me know. I'm still looking for some kind of app note or example to first test with.

Here is the location of the bootloader.hex file:

SDK6.1/nrf51822/Board/nrf6310/device_firmware_updates/bootloader/arm/_build/bootloader.hex

I would start with the HRS example(with DFU):

C:\Nordic Semiconductor\nRF51_SDK_7.1.0_372d17a\examples\ble_peripheral\ble_app_hrs\pca10028\experimental_s110_with_dfu\arm.

There is no app note but I think you are looking for this:

developer.nordicsemi.com/.../a00066.html

So we need to open that project and build it to get access to the bootloader hex? There's no pre-built, standard hex like there is with the soft device?

I don't think we have any pre-build bootloader. But it should not be any problem to build one using KEIL, out of the box. @lab-stellios: Do you still have any trouble to have a bootloader.hex file to use ?

I ordered a new development kit and gave up trying to follow new documentation with old hardware.

@lab-stellios: Just a comment, you can always find earlier documentation here in the list.
