Where can I find example code source for nrf51 dev kit ?

[Thomas]

Hi, I have bought the nRF51 development kit. I have downloaded source code for nRF51822. This comes with LOTS of examples but I suspect the codes are not for my board. Is there something similar for nRF51 ?

Here is the directory structure of what I have :

What am I missing ? My board is pca10028. Some examples work fine (ble_app_hrs) some don't (blinky example) Any idea ? I feel a little lost.

Thanks

Examples for without soft device(blue stack) are in nrf6310 folder, for application with Softdevice S110 or with S120 , you will find it under nrf6130->s110/s120 folders. For more applications templates based on S110 you can find it in pca10000/10001 board. Although i have not used pca10028 but it should work if chipset is same across the board.

For NRF51-DK (PCA10028) the SDKs are available here. There is a pointer in the NRF51-DK User Guide, the version 7.x.x and 8.x.x SDKs directly support PCA10028.

The SDK you have is intended for older versions of Nordic's nRF51422/822 development platform. While those projects can generally be made to run on the newer hardware, I think you'd be well advised to start with demo projects already set up to run on PCA10028.

You should also see the nRF51_Series_Compatibility_Matrix document to get your arms around which IC hardware, SDK, softdevice and development hardware versions are intended to work together.

Thanks a lot for this link!! I have successfully made the blink example work. As for examples that involve s110, I have tried ble_app_hrs. I did JLinkExe loadbin s110.v7.hex 0 then loadbin ble_app_hrs.hex 0x16000 (then r/g/exit) I can connect but no beats are shown on the iOS app. Is it a problem of .hex instead of .bin ? I have used s110.v7.hex (in components/softdevice/s110) and the one downloaded in s110 v8

never mind, I have tested with BLEScanner and it works fine, so I guess the iOS app has a problem. Thank you very much, I have been stuck on this for months

Great, I'm glad that helped. I've had good luck with various 7.x.x SDK projects on pca10028.
