Issues in X-CUBE-BLE1 with MDK-ARM (Keil) !!!

Hi,

I was recently at ST Booth, Embedded world in Nürnberg. I received two development kits - STM32 dev kit (NUCLEO--L053R8) and Bluetooth add on board (X-NUCLEO-IDB04A1). Microcotroller I have on dev kit is STM32L053R8T6.

To begin with I downloaded Bluetooth low energy BlueNRG software for STM32, expansion for STM32Cube (part number : X-CUBE-BLE1).

I am using a 32K evaluation version Keil MDK-ARM compiler. I could flash the software but it did not work for me. When I tried to scan via BlueNRG app in my android phone, I never saw the device. To debug the problem I did a single stepping through the code and found code to jump at places. So I thought may be it is a optimization problem. So decreased the optimization level at compile time. It did not work.

Then I used the IAR EWARM compiler for same project and it did work.

So I think source code has no problem but MDK-ARM settings are not correct. Could you please suggest me solution to get it work along ARM-MDK.

My Keil MDK-ARM version : µvision 5.14.0.0

Thanks.

I'm not sure what that means, does the code Hard Fault, or is otherwise evidently wrong? With no optimization did it perform differently.
