Strange current in Long Range Beacon

[Mateusz Gancarczyk]

Hi, I measure current in beacon in Long Range mode. Behind 3 current peaks witch represent TX on channel CH37 CH38 CH39 there is a strange current peak, witch I don't understand. When I switch to 1MBps this current peaks dosn't occur.

Here is my configuration for adv init:

 

/* long range*/
		m_adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;
    m_adv_params.primary_phy   	 = BLE_GAP_PHY_CODED;
    m_adv_params.secondary_phy 	 = BLE_GAP_PHY_CODED;
/* 1MBPS  */
//    m_adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;

I thinkg no.

Here is my full adv init:

static void advertising_init(void)
{
    manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;
		
    manuf_specific_data.data.p_data = (uint8_t *)beaconData;
    manuf_specific_data.data.size   = APP_BEACON_INFO_LENGTH;

    // Build and set advertising data.
    memset(&advdata, 0, sizeof(advdata));

    advdata.name_type             = BLE_ADVDATA_NO_NAME;
    advdata.flags                 = flags;
    advdata.p_manuf_specific_data = &manuf_specific_data;

    // Initialize advertising parameters (used when starting advertising).
    memset(&m_adv_params, 0, sizeof(m_adv_params));
		
/* long range*/
		m_adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;
    m_adv_params.primary_phy   	 = BLE_GAP_PHY_CODED;
    m_adv_params.secondary_phy 	 = BLE_GAP_PHY_CODED;
/* 1MBPS  */
//    m_adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;

		m_adv_params.p_peer_addr     = NULL;    // Undirected advertisement.
    m_adv_params.filter_policy   = BLE_GAP_ADV_FP_ANY;
    m_adv_params.interval        = NON_CONNECTABLE_ADV_INTERVAL;
    m_adv_params.duration        = 0;       // Never time out.
    m_adv_params.scan_req_notification = 0;


    err_code = ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
    APP_ERROR_CHECK(err_code);

    err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
    APP_ERROR_CHECK(err_code);
}
