Using NRF Beacon 51822 via OTA?

[TiBoo]

Hello, I am quite new to Beacon development. I am trying to use the examples of NRF SDK 10.0 on the NRF Beacon. I would like to "install" the application via OTA. I tried the example in the folder "examples\peripheral\blinky\pca10028\blank\arm5_no_packs". I used Keil v5 to generate a build folder.

I uploaded the hex file to the dropbox and loaded it with the nrfBeacon app. Now I need a init (.dat) file. I am not sure how I could create it on Windows. Could you help me to generate such a file so that I can upload an example application? I tried the examples but could not execute the python script without an error. When I try to use nrfutil with the command "nrfutil dfu genpkg --application nrf51422_xxac.hex myapp.zip", I get the error "wrong value for size". I installed Master Control Panel 3.10.0.14.

Hello,

It is required to specify the softdevice version in the init packet as this is being checked by the bootlaoder (at least for the SDK examples).

Example arguments for creating a generic distribution .zip (0xFFFE => accept any SD):

nrfutil dfu genpkg ../application.zip --application <application>.hex --application-version 0xFFFFFFFF --dev-revision 0xFFFF --dev-type 0xFFFF --sd-req 0xFFFE

Also, you can find pre-made distribution packets here: \nRF51_SDK_10.0.0\examples\dfu\ble_dfu_send_hex\test_images_update_nrf51\
