nRF52 demo board BLE examples not working in Keil MDK-Lite

[MichelG]

I have an nRF52 dev board and I'm trying to build and download some of the example programs. The example files were downloaded using the Pack Installer in Keil MDK-Lite.

When I build and download the Blinky or PWM example projects everything works fine.

When I try the same thing with BLE examples they seem to build without errors but the .hex file created is small (<32KB) and they do not run on the dev board.

I noticed that the examples that come with nRF5_SDK have pre-compiled .hex files which are typically >300KB for the same BLE examples. When I copy those .hex files to the dev board they function properly.

Are the BLE example programs too big for MDK-Lite (32KB limit)?

Hi,

Unfortunately some examples might take a lot of code size, the alternatives here are buying a commercial license for Keil or other supported IDEs, or using free alternatives such as GCC. You can find a tutorial for GCC and Eclipse here.

Best regards,
