SDK14 ble_periphal example dont work

[kejta]

Hi, i downloaded new SDK14 with example, after i upload hex from example in ble_peripheral/ble_app_hrs I use s132 / nrf52

program stuck here :

ret_code_t nrf_sdh_enable_request(void)
{
    ret_code_t ret_code;

    if (m_nrf_sdh_enabled)
    {
        return NRF_ERROR_INVALID_STATE;
    }

    m_nrf_sdh_continue = true;

    // Notify observers about SoftDevice enable request.
    if (sdh_request_observer_notify(NRF_SDH_EVT_ENABLE_REQUEST) == NRF_ERROR_BUSY)
    {
        // Enable process was stopped.
        return NRF_SUCCESS;
    }

    // Notify observers about starting SoftDevice enable process.
    sdh_state_observer_notify(NRF_SDH_EVT_STATE_ENABLE_PREPARE);

    nrf_clock_lf_cfg_t const clock_lf_cfg =
    {
        .source        = NRF_SDH_CLOCK_LF_SRC,
        .rc_ctiv       = NRF_SDH_CLOCK_LF_RC_CTIV,
        .rc_temp_ctiv  = NRF_SDH_CLOCK_LF_RC_TEMP_CTIV,
    #ifdef S132
        .accuracy      = NRF_SDH_CLOCK_LF_XTAL_ACCURACY
    #else
        .xtal_accuracy = NRF_SDH_CLOCK_LF_XTAL_ACCURACY
    #endif
    };

    #ifdef ANT_LICENSE_KEY
        ret_code = sd_softdevice_enable(&clock_lf_cfg, app_error_fault_handler, ANT_LICENSE_KEY);
    #else
        ret_code = sd_softdevice_enable(&clock_lf_cfg, app_error_fault_handler);
    #endif

    if (ret_code != NRF_SUCCESS)
    {
        return ret_code;
    }

on ret_code = sd_softdevice_enable(&clock_lf_cfg, app_error_fault_handler);

same problem is, if i recomplile whole project a load new one.

could someone help me, where is the problem ? regards

1. Where exactly in that code does your program get stuck?
2. Are one of those functions returning an error?
3. Have you debugged like this?
4. Are you using a custom board, or a development kit?
5. If you are using a custom device, are you using the correct LF clock source? Do you have an external low frequency crystal?

[MartinBL]

Sorry. Read your question again. Is sd_softdevice_enable() returning an error code? Or is it just stuck?

[kejta]

SVCALL(SD_SOFTDEVICE_ENABLE, uint32_t, sd_softdevice_enable(nrf_clock_lf_cfg_t const * p_clock_lf_cfg, nrf_fault_handler_t fault_handler)); eclipse tell me No source available for "0x90c" if i load softdevice.

4. i am using develepment kit LAIRD BL652

[MartinBL]

According to chapter 2.1 "Specification Summary" in the Datasheet for the BL652 module there are no 32.765kHz crystal on the module:

There seems to be one on the LAIRD BL652 development kit though, but it has to be connected to the module with solderbridges SB8 & 9:

You can also change the LF clock source in your code in sdk_config.h by setting:

// <o> NRF_SDH_CLOCK_LF_SRC  - SoftDevice clock source.
 
// <0=> NRF_CLOCK_LF_SRC_RC 
// <1=> NRF_CLOCK_LF_SRC_XTAL 
// <2=> NRF_CLOCK_LF_SRC_SYNTH 

#ifndef NRF_SDH_CLOCK_LF_SRC
#define NRF_SDH_CLOCK_LF_SRC 0 // <- Set to zero to use internal RC oscillator
#endif

Not help, same problem. :(
