You shoud check that you have set the correct RAM/Flash settings in your project for your PCA20006 board use. The PCA10028 (nRF51 DK) use the nRF51422 QFAC IC with 32KB RAM and 256KB Flash. Only last revision of the beacon kit (v 1.3.0) use nRF51822 CFAC chip with same amount of RAM. Previous revisons have CEAA chip with 16KB RAM. Softdevice should match the one supported by the SDK of your example. You also need to make sure the softdevice is supported by the chip revison on the board.

Hi,Jorgen, Thanks for your reply. This problem has been solved. But unfortunately there is another problem, the example I based on my code is the ble_uart, and when I want to transfer the code from dk board to a beacon board from pca10028 to pca20006 by using the debug out function on dk board, it didn't work. At this time do I need to change the soft device function related to the beacon board instead of that with pca10028 dk board?

Best reagrads, Looooogh

Hi,

If the board does not have buttons, you should remove the bsp_btn_ble library, as it does nothing usefull without buttons.

I don't know which example you have based your code on, but the procedure to remove it should be similar for most examples in the SDK (I have based this on the ble_app_hrs example):

Remove call to bsp_btn_ble_sleep_mode_prepare() in sleep_mode_enter().
Remove dispatch of BLE events to the bsp_btn_ble_on_ble_evt(p_ble_evt); handler in ble_evt_dispatch.
Remove initialization of bsp_btn_ble_init() in buttons_leds_init().
Exclude/remove source file bsp_btn_ble.c from project.
You can also remove | BSP_INIT_BUTTONS from call to bsp_init(), but this code will not have any effect when BUTTONS_NUMBER = 0.

Best regards,

Jørgen
