Hi endnode, my problem is solved :D all I need to do is changing CFLAGS += -Wall -Werror -O0 -g3to CFLAGS += -Wall -Werror -O3 -g3. I don't know why :)))) anyway, thanks for your help, you are my savior :')

Oh you are mixing different API and SD versions? That will most probably fail terribly;) Why you don't stick with the SD which is recommended with (delivered in) SDK version you use (especially if you don't know how to migrate to different one yourself)? Basically you need SD HEX file version on the chip in sync with ROM/RAM regions' setting in your project (typically LD script for GCC or project settings in Keil/IAR) and SD API headers which match the version. There is hardly any different solution to this basic set-up;)

When I define BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT in my code, I get an error that it is redefined, because BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT is defined in ble_gap.h, which is in the following sequence: BLE_Drv.h -> ble_advertising.h -> ble.h -> ble_gap.h .This is the reason why I can compile my code without error and flash the hex file to the chip. But unfortunately, the error 0x3001 is still there :(((( after searching, I get an information that wrong Softdevice version can cause that error. In the example in the Software_development_kit, it uses the version 4.0.2 and I am using the version 5.0.0-1.alpha. But when I try to flash the version 4.0.2 into the nRF52832 chip, nothing works :(((( I am searching for another solution

Sorry, also my mistake. BLE_GAP_CFG_ROLE_COUNT is constant to distinguish which variant of sd_ble_cfg_set you are calling, that's defined in SD API. However you need to define BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT and you certainly have it in your project unless you couldn't compile it (and hence couldn't load it to chip and observe 0x3001 error code). If you don't know how many GAP Peripheral connection links you need to support in your FW then I cannot help you, that's something you need to decide;)

My mistake!! I forgot defining BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT and BLE_GAP_CFG_ROLE_COUNT :(( which value should them be?

Looking to your code and there seems to be no obvious mistake. If you say the error code is thrown at err_code = sd_ble_cfg_set(BLE_GAP_CFG_ROLE_COUNT, &ble_cfg, ram_start); then I don't see two crucial values: how are BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT and BLE_GAP_CFG_ROLE_COUNT defined?

Hi endnode, I updated the question and attached the C source and the header file. Thanks for helping me :D

I'm afraid it will need larger code sample. Have you used some working SDK example as baseline? And I'd prefer to update the question to see all the things at one place so others can answer easily...

memset(&ble_cfg, 0, sizeof(ble_cfg)); ble_cfg.gap_cfg.role_count_cfg.periph_role_count = BLE_GAP_ROLE_COUNT_PERIPH_DEFAULT; ble_cfg.gap_cfg.role_count_cfg.central_role_count = 0; ble_cfg.gap_cfg.role_count_cfg.central_sec_count = 0; err_code = sd_ble_cfg_set(BLE_GAP_CFG_ROLE_COUNT, &ble_cfg, ram_start); APP_ERROR_CHECK(err_code);

And what parameters you supply there?:) It looks strange because 0x3001 means BLE_ERROR_NOT_ENABLED and that should not be returned by sd_ble_cfg_set, unless you use some variant which must be called after SD is enabled.

Hi endnode, the function is "sd_ble_cfg_set".

Which sd_ function call returns this error? If you look its header then you should get some basic hints what went wrong.
