Hi,

You can try something like this:

uint8_t * ble_advdata_manuf_data_find(const ble_data_t * p_adv_data, uint8_t * manuf_data_length)
{
    uint16_t data_offset = 0;
    *manuf_data_length = ble_advdata_search(p_adv_data->p_data,
                                         p_adv_data->len,
                                         &data_offset,
                                         BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DATA);

    return &p_adv_data->p_data[data_offset];
}

....

static void ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context)
{
    ....

    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_ADV_REPORT:
            ...
            uint8_t manuf_data_len;
            uint8_t * manuf_data = ble_advdata_manuf_data_find(&p_gap_evt->params.adv_report.data, &manuf_data_len);

The function ble_advdata_manuf_data_find() will return a pointer to your manufacturer data and set manuf_data_length to the length of the data.
