[nRF52832 + SDK15.2] NRF_FAULT_ID_SDK_ERROR

[BruceLee]

Hi, I'm Developing Custom Board with nRF52832.

When I execute my custom code (by referring to ble_app_template example), an error occured.

First, my hardware spec below,

• MCU : nRF52832QFAA
• SDK : nRF5_SDK_15.2.0_9412b96
• SoftDevice : s132_nrf52_6.1.0_softdevice

The error is fault error. so, system processing "app_error_fault_handler".

then I check parameter in "app_error_fault_handler",

• id : 0x00004001 (NRF_FAULT_ID_SDK_ERROR)
• pc : 0x00000000
• info : 0x20007BB8

I found this error is "NRF_FAULT_ID_SDK_ERROR".

but I don't know why this error ouccred, and How to fix it.

Best Regards

the fault error occured at peer_manager_init() function.

static void peer_manager_init(void)
{
    ble_gap_sec_params_t sec_param;
    ret_code_t           err_code;

    err_code = pm_init();
    APP_ERROR_CHECK(err_code);

    memset(&sec_param, 0, sizeof(ble_gap_sec_params_t));

    // Security parameters to be used for all security procedures.
    sec_param.bond           = SEC_PARAM_BOND;
    sec_param.mitm           = SEC_PARAM_MITM;
    sec_param.lesc           = SEC_PARAM_LESC;
    sec_param.keypress       = SEC_PARAM_KEYPRESS;
    sec_param.io_caps        = SEC_PARAM_IO_CAPABILITIES;
    sec_param.oob            = SEC_PARAM_OOB;
    sec_param.min_key_size   = SEC_PARAM_MIN_KEY_SIZE;
    sec_param.max_key_size   = SEC_PARAM_MAX_KEY_SIZE;
    sec_param.kdist_own.enc  = 1;
    sec_param.kdist_own.id   = 1;
    sec_param.kdist_peer.enc = 1;
    sec_param.kdist_peer.id  = 1;

    err_code = pm_sec_params_set(&sec_param);
    APP_ERROR_CHECK(err_code);

    err_code = pm_register(pm_evt_handler);
    APP_ERROR_CHECK(err_code);
}

I found reason.

#define SEC_PARAM_BOND 0

to

#define SEC_PARAM_BOND 1

then worked.
