s110 softdevice .hex & s110 DFU bootloader

[Algorkorea]

As part of some testing, I downloaded some wrong files and seem to have contaminated the default boot files. So now when I try to download the NORDIC hex files, i get an error.

I found the s110 softdevice version 7.1.0 on the NORDIC website.

I believe I could use this softdevice file. But where can i find the DFU bootloader files ? Could you help me please . Thank you.

Hi,

You need to contact the Ezario support team for this particular query.

Best regards,

I did send an email to ONSEMI. But i was wondering if i might find an answer here too. I was hoping the DFU bootloader must be a generic file that I could upload to the NORDIC device (nRF51822) that I am using with my Ezairo chip.

There are generic bootloaders that are part of the SDK, for example you can find one for SD 110 in SDK 7.2 under SDK 7.2\nRF51_SDK_7.2.0_cf547b5\examples\dfu\hci_dfu_send_hex\test_images_dual_bank_update however I am quite sure the one you are looking for is application specific.

Also note that the latest SDK is SDK 11, but I assume the Ezario device is feature locked to SDK ~7

Thank you. I got a reply from ONSEMI as well. so i'll test the bootloader they provided and later i might test this bootloader as well for the sake of it.
