c# - Get last call duration using AT+CLCC command -


I have coded a program and automatically dialed the last call when the phone is connected to a laptop. Duration is obtained. I command AT + CLCC to get the status of the current call. However this should return some string values ​​back as ....... etc., I have not found anything like this yet ... this is my code Is .. 

  _serialPort.BaudRate = 9600; _serialPort.Parity = Samata. One; _serialPort.DataBits = 8; _serialPort.StopBits = StopBits.One; _serialPort.Handshake = Handshake.None; // Set the read / write time _serialPort.ReadTimeout = 500; _serialPort.WriteTimeout = 500; _serialPort.Open (); _serialPort.DtrEnable = true; _serialPort.RtsEnable = true; String phonen = ""; // string message; If (! _serialPort.IsOpen) {_serialPort.Open (); } _serialPort.WriteLine ("AT \ r"); {Console.WriteLine ("Enter the phone number:", the phone); Phonenr = Console.ReadLine (); _serialPort.WriteLine ("ATD" + PhoneRar + ";" + "\ r"); Console.WriteLine ("Ring ..."); Thread.Sleep (10000); _serialPort.WriteLine ("+ CLCC AT"); _serialPort.DataReceived + = New SerialDataReceivedEventHandler (DataReceivedHandler); // as a separate function .... Private Static Blank Dataraisevandler (Object Sender, Serial Data Receive Event Eg) e SerialPort Sp = (SerialPort) Sender; String indenta = sp.ReadExisting (); Console WrightLine ("Received Data:"); Console.Write (indata); }   
 What is wrong with this code ???? How can I get feedback as a format ... etc ???  
  
 
 
 AT + CLCC order  no  provide information about the last call . It provides information about a call (during dialing / playing / waiting etc.)  during the time . Read for detailed information.  
 I think that you can automatically output the last call description to the terminal on the terminal when the call is disconnected, but I am not sure that it provides call duration. is. You may need to manually monitor the time recording with your app  
 I have also seen your other posts. I use a normal serial port terminal (Putty or Terminal etc.) to communicate with the phone and understand the concept, before using programming to automate the task.

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example. End of ...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
