SVCALL resets nRF51

[ypearson]

Device: NRF51-DK

I'm using GDB+OpenOCD to step thru code and it appears that the nrf51 resets itself after calling:

SVCALL(SD_BLE_GAP_ADV_START, uint32_t, sd_ble_gap_adv_start(ble_gap_adv_params_t const *p_adv_params));

in file: ble_gap.h

I used nrfjprog to program the soft device and code.

I'm using the example code:

sdk/examples/ble_peripheral/ble_app_uart

Any ideas why ?

thanks,

static void advertising_init(void) { uint32_t err_code; ble_advdata_t advdata; ble_advdata_t scanrsp;

// Build advertising data struct to pass into @ref ble_advertising_init.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type          = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = false;
advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
scanrsp.uuids_complete.p_uuids  = m_adv_uuids;

ble_adv_modes_config_t options = {0};
options.ble_adv_fast_enabled  = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_INTERVAL;
options.ble_adv_fast_timeout  = APP_ADV_TIMEOUT_IN_SECONDS;

err_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code);

}
