hcitool scan 不扫描设备 hcitool 扫描：不支持操作

问题描述

我正在使用 hcitool 从 iMx6 设备扫描蓝牙设备（Windows PC）。我运行了以下命令，结果“不支持操作”。我该如何解决这个问题？

public bool reserveRoom() //function for reserving a room
{
    bool allow = true;
    con.Open();

    SqlCommand cmd = new SqlCommand("insert into Rooms (StudentID,RoomType,Date,StartingTime,DurationInHour,FinishingTime) values (@studentid,@roomtype,@date,@startingtime,@duration,@finishingtime)",con);

    SqlCommand cmd2 = new SqlCommand("select StudentID from Students where TPEmail = '" + StudentEmail + "'",con);

    SqlDataReader rd = cmd2.ExecuteReader();
    int id = 0;

    while (rd.Read())
    {
        id = rd.GetInt32(0);
    }

    rd.Close();

    MessageBox.Show(Date.Date.ToString());

    SqlCommand cmd3 = new SqlCommand("select StartingTime from Rooms where RoomType = '" + RoomType + "' and Date = '" + Date.Date.ToString("dd/MM/yyyy") + "'",con) ;

    SqlCommand cmd4 = new SqlCommand("select count(*) from Rooms where RoomType = '" + RoomType + "'" + " and Date ='" + Date.Date.ToString("dd/MM/yyyy") + "'",con);

    int count = Int32.Parse(cmd4.ExecuteScalar().ToString());

    SqlDataReader rd2 = cmd3.ExecuteReader();

    String[] startingTime = new string[count];
    //int ident = 0;
    int index = 0;

    while (rd2.Read())
    {
        startingTime[index] = rd2.GetTimeSpan(0).ToString();
        index += 1;
    }

    rd.Close();

    cmd.Parameters.AddWithValue("@studentid",id);
    cmd.Parameters.AddWithValue("@roomtype",RoomType);
    cmd.Parameters.AddWithValue("@date",Date.Date);

    string timeStart = (Time1 + ":" + Time2);
    cmd.Parameters.AddWithValue("@startingtime",TimeSpan.Parse(timeStart));

    double doubleDuration = Int32.Parse(DurationHour) + ((Double.Parse(DurationMinute)) / 60);
    cmd.Parameters.AddWithValue("@duration",doubleDuration);

    int hour = Int32.Parse(Time1) + Int32.Parse(DurationHour);
    int min = Int32.Parse(Time2) + Int32.Parse(DurationMinute);

    if (min >= 60)
    {
        min -= 60;
        hour += 1;
    }

    string timeFinish = (hour + ":" + min);
    cmd.Parameters.AddWithValue("@finishingtime",TimeSpan.Parse(timeFinish));

    int i = cmd.ExecuteNonQuery();

    if (i != 0)
    {
        MessageBox.Show("Reservation successful.");
    }
    else
        MessageBox.Show("Unable to reserve");

    foreach (string item in startingTime)
    {
        TimeSpan timeItem = TimeSpan.Parse(item);

        if (Int32.Parse((timeItem - TimeSpan.Parse(timeFinish)).ToString()) >= 0)
        {
            MessageBox.Show("Accept");
        }
    }

    con.Close();
    return allow;
}

问候，
