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

Hi Jørgen, Thank you for your suggestions, I am about to try the merge hex, When I open an example from Keil, there is no soft device separate "target" as mentioned in the guide, there is an nRF_SoftDevice section of the main application that has the s_132_nrf52_xxxx hex file and the softdevice_handoer.c file. Right Clicking gives me "Options for component class" rather than "target".

Many Thanks

You need to select the target in the dropdown meny like this:

Thanks Jørgen, I tried that and it says "Erase failed" "Error: Flash Download failed - "Cortex-M4" " I tried the merge hex and it created a 374kb hex file, I put this on the JLINK Drive but it seems to do nothing still? Many Thanks

You may have to erase the board depending on what you have flashed already. Which files did you merge? I merged the S132 v3.0.0 softdevice with the ble_app_beacon hex file compiled from pca10040 project, ending up at 365kB. That works fine when copied to the board.
