Compiled SDK example does not work on nRF51 DK board

[Bazza]

Example ble_app_uart compiled in Keil 5 O.K but the resultant HEX file in the build folder is only 34K whereas the hex file in the hex folder is 335k. I followed the tutorial for first time use and everything seemed to go fine until I tried flashing the hex. I had previously flashed S-130 without issue. The SDK 335k hex file works fine on the board.

Any ideas solutions gratefully welcome.

Hi,

The hex-file generated by compilation does not include the softdevice. You have to flash the softdevice separately. The precompiled hex-files in the hex-folder has the softdevice merged in (you can do this with your own application using mergehex if you want to).

Best regards,

Jørgen
