nRF52832 BLE STK error

[huaminhtuan]

Hi everyone,

I am using nRF52832 chip and trying to use BLE on that. I flashed SoftDevice. When I flash the "ble_app_uart" example, error code 0x3001 occurs. the function "sd_ble_cfg_set" call return the error. I attached the header and the source file also. BLE_Drv.c BLE_Drv.h Can you help me please? Thanks!

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

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?

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

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;)

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
