NRF52 BLE examples not working with gcc

[Mohammad Amin]

After working with NRF51822, I decided to go for NRF52832, and I bought some modules that have NRF52. I am using GCC and SDK13. I installed the S132 soft device which is in "sdk13\components\softdevice\s132\hex" using NRFGo. Then, I compiled and tested the blink example which is in "blinky\pca10040\s132", and it worked perfectly. However, none of BLE examples don't work at all. I tested many samples like "ble_peripheral\ble_app_beacon". However, the device doesn't advertise. I've done all the necessary things completely. Even the blinky example works, and I don't know why BLE examples are not working. Please, help me

This is the module that I am using

Hi,

Assuming that the board don't have a LFCLK crystal oscillator, you will need to use the LFCLK RC oscillator. For SDK 13 you can change this in ble_stack_init()

Code snippet:

static void ble_stack_init(void)
{
    ret_code_t err_code;

    nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;
    clock_lf_cfg.source = NRF_CLOCK_LF_SRC_RC;
    clock_lf_cfg.rc_ctiv = 32;
    clock_lf_cfg.rc_temp_ctiv = 2;
        

    // Initialize the SoftDevice handler module.
    SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);
    .
    .
    .

Hello Sigurd , Thank you for the quick response. I have tried this on the nrf52832 dev board with the 32khz xtal physically removed. It seems to hang on boot. I'm ordering another dev board in case this one has been damaged. But it seems to run fine with the other non ble examples.
