NRF52 DK BLE Not Working?

[AWUk]

Hi, I downloaded the latest SDK V12, coped the example HEX from the BLE Beacon and it worked fine. I tried to then compile using Keil, it compiled, but I noticed that in the SoftDevice (132) version was different than the SDK (3.0 in the SDK vs 2.0.0-7 alpha in Keil Pack), so I copied the appropriate soft device hex file onto the demo board then the compiled hex, nothing! I tried the blank Blinky app and that works fine, all 4 LEDs go blink.

Am I missing something? I tried copying each HEX file (SD 132) and the app together and separately, I have tried different offsets (1C, 1B, 1F etc) as suggested on other questions, I even compiled the SDK 12's version using IAR and re-uploading SD 132 V3, still nothing.

I have PCA10040 V1.1.0 2016.16 written on the DK if that helps?

Cheers

Hi,

If you want to use drag-and-drop programming (copying the hex file to JLINK drive), you need to merge softdevice and application into one file using mergehex. The board will be erased when programming the hex file using this method, removing your application or softdevice when you copy the second file.

You can program both softdevice and application to the board directly from keil. You can also program the board using nrfjprog commandline utility.

Best regards,

Jørgen

I coped 2.0.0 7 alpha by mistake, this now works when copying for SD 132 V3, when I load the project into Keil and select the softdevice from target it comes up with missing .h file errors, the application compiles fine though, any ideas? Is there an online resource for going through how the demos work to create our own for the softdevice? I am looking at getting one nRF52 DK board listening to several other nRF52 DK boards with BTLE, used for wireless sensors. Many Thanks
