Hi.
Why longer advertising data destroy device ?
When I set length of advertising data to 20bytes in advertising_init(), device will crash and I can't download new firmware anymore and nothing can detect NRF51DK connected to PC via USB.
I have set SHORT_NAME and MANUFACTURE_DATA.
static void advertising_init(char * data)
{
uint32_t err_code;
ble_advdata_t advdata;
uint8_t flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
ble_advdata_t scanrsp;
ble_uuid_t adv_uuids[] = {{BLE_JACKX_SERVICE_UUID, BLE_UUID_TYPE_BLE}};
// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_SHORT_NAME;//BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = false;
advdata.flags.size = sizeof(flags);
advdata.flags.p_data = &flags;
ble_advdata_manuf_data_t manuf_data; // Variable to hold manufacturer specific data
manuf_data.company_identifier = 0x0; // Nordics company ID
manuf_data.data.p_data = (uint8_t*)data;
manuf_data.data.size = 18;
advdata.p_manuf_specific_data = &manuf_data;
memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
scanrsp.uuids_complete.p_uuids = adv_uuids;
err_code = ble_advdata_set(&advdata, NULL);
APP_ERROR_CHECK(err_code);
// Initialize advertising parameters (used when starting advertising).
memset(&m_adv_params, 0, sizeof(m_adv_params));
m_adv_params.type = BLE_GAP_ADV_TYPE_ADV_IND;
m_adv_params.p_peer_addr = NULL;
m_adv_params.fp = BLE_GAP_ADV_FP_ANY;
m_adv_params.interval = APP_ADV_INTERVAL;//APP_CONFIG_ADV_INTERVAL;
m_adv_params.timeout = APP_ADV_TIMEOUT_IN_SECONDS;//0;//APP_ADV_TIMEOUT_IN_SECONDS;//APP_CONFIG_ADV_TIMEOUT;
}
