There was an unexpected issue configuring beacon ad packages. The task is to transfer as much data as possible in beacon mode. For this, I want to include the scan responce package. But somehow I can't do it.
Here is the code:
#define BEACON_DATA_MAX_SIZE 27
#define BEACON_RSP_DATA_MAX_SIZE 27
// ADV packed declaration
static ble_advdata_t m_beacon_advdata;
static ble_advdata_manuf_data_t m_manuf_specific_data;
static uint8_t m_beacon_data_buf[BEACON_DATA_MAX_SIZE];
// ADV scan responce packed declaration
static ble_advdata_t m_beacon_rspdata;
static ble_advdata_manuf_data_t m_manuf_specific_rsp_data;
static uint8_t m_beacon_rsp_data_buf[BEACON_DATA_MAX_SIZE];
static uint8_t m_enc_advdata_beacon[BLE_GAP_ADV_SET_DATA_SIZE_MAX]; /**< Buffer for storing an encoded advertising set. */
static uint8_t m_enc_advdata_rsp_beacon[BLE_GAP_ADV_SET_DATA_SIZE_MAX]; /**< Buffer for storing an encoded advertising set. */
static uint8_t m_enc_advdata[BLE_GAP_ADV_SET_DATA_SIZE_MAX]; /**< Buffer for storing an encoded advertising set. */
static uint8_t m_enc_srdata[BLE_GAP_ADV_SET_DATA_SIZE_MAX]; /**< Buffer for storing an encoded advertising set. */
static ble_gap_adv_params_t m_adv_params_beacon; /**< Parameters to be passed to the stack when starting advertising. */
static ble_gap_adv_params_t m_adv_params; /**< Parameters to be passed to the stack when starting advertising. */
static uint8_t m_adv_handle = BLE_GAP_ADV_SET_HANDLE_NOT_SET; /**< Advertising handle used to identify an advertising set. */
/**@brief Struct that contains pointers to the encoded advertising data. */
static ble_gap_adv_data_t m_adv_data_beacon =
{
.adv_data =
{
.p_data = m_enc_advdata_beacon,
.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX
},
.scan_rsp_data =
{
.p_data = m_enc_advdata_rsp_beacon,
.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX
// .p_data = NULL,
// .len = 0
}
};
static void advertising_beacon_init()
{
uint32_t err_code;
m_manuf_specific_data.data.p_data = m_beacon_data_buf;
m_manuf_specific_data.data.size = BEACON_DATA_MAX_SIZE;
m_manuf_specific_rsp_data.data.p_data = m_beacon_rsp_data_buf;
m_manuf_specific_rsp_data.data.size = BEACON_RSP_DATA_MAX_SIZE;
// Build and set advertising data.
memset(&m_beacon_advdata, 0, sizeof(m_beacon_advdata));
memset(&m_beacon_rspdata, 0, sizeof(m_beacon_rspdata));
m_beacon_advdata.name_type = BLE_ADVDATA_NO_NAME;
m_beacon_advdata.p_manuf_specific_data = &m_manuf_specific_data;
m_beacon_rspdata.name_type = BLE_ADVDATA_NO_NAME;
m_beacon_rspdata.p_manuf_specific_data = &m_manuf_specific_rsp_data;
// Initialize advertising parameters (used when starting advertising).
memset(&m_adv_params_beacon, 0, sizeof(m_adv_params_beacon));
m_adv_params_beacon.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;
m_adv_params_beacon.p_peer_addr = NULL; // Undirected advertisement.
m_adv_params_beacon.filter_policy = BLE_GAP_ADV_FP_ANY;
m_adv_params_beacon.interval = NON_CONNECTABLE_ADV_INTERVAL;
m_adv_params_beacon.duration = 0; // Never time out.
m_adv_params_beacon.primary_phy = BLE_GAP_PHY_1MBPS;
m_adv_params_beacon.secondary_phy = BLE_GAP_PHY_1MBPS;
m_adv_params_beacon.max_adv_evts = 3;
err_code = ble_advdata_encode(&m_beacon_advdata, m_adv_data_beacon.adv_data.p_data, &m_adv_data_beacon.adv_data.len);
APP_ERROR_CHECK(err_code);
err_code = ble_advdata_encode(&m_beacon_rspdata, m_adv_data_beacon.scan_rsp_data.p_data, &m_adv_data_beacon.scan_rsp_data.len);
APP_ERROR_CHECK(err_code);
}
static void advertising_start_beacon(void)
{
ret_code_t err_code;
sd_ble_gap_adv_stop(m_adv_handle);
err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data_beacon, &m_adv_params_beacon);
APP_ERROR_CHECK(err_code);
err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
APP_ERROR_CHECK(err_code);
}
The error occurs in the advertising_start_beacon function when calling sd_ble_gap_adv_set_configure.
sd_ble_gap_adv_set_configure returns NRF_ERROR_INVALID_PARAM.
I can't figure out what the problem is. Thanks!
