Greetings all.


I am struggling to successfully network my android devise with a server I have on the same Wifi network.

Any guidance would be much appreciated.

I want to view some sensor values on my android devise.


I have a server writing a message on a given IP and Port. (This happens to be a arduino wifi project, simply I am broadcasting two sensor values)

I want to view these sensor values on my android devise. (I can do this using my pc/java processing, telnet, etc, but not with android processing)

I am aware of oscP5 libraries and such but, for my simple little set up all I require to do is to display the message I am broadcasting on my android devise as it sits as a client. Just seeing the message on the screen would be great! For example I have used ConnectBot and I can see them this way. I'd rather make my own program so I can develop it further.

Please suggest any areas I should research! (Networking with Java... I gathered:) )


Many thanks guys.


EDIT: Yes i am a newbie, but i can make android applications minus networking stuff.

Hi all.

I am trying to read data from a particular port and IP with android processing.

Does anyone know how I would do this?


This is the same as using telnet on PC to look at a particular message and port.



Thanks.

I have a server sending a constant stream of stuff onto a wifi network. (This happens to be a arduino wifi/project, the constant stream is just temporary until I get my head round this).

The message is constructed:

R, Value0, Value1, R, Value0, Value1, R....etc


I want to use this message on my android devise to do stuff, such as present some sensor information to the user.


The simple question is - How do I read this stream from my server in android processing with the OscP5 library?
My code(that is probably completely in the wrong direction):

1. import oscP5.*;
2. import netP5.*;
   
   
   
3. OscP5 oscP5tcpServer;
   
   
4. OscP5 oscP5tcpClient;
   
   
5. NetAddress myServerAddress;
   
   
6. void setup() {
   
    
7.  oscP5tcpClient = new OscP5(this, "192.168.0.20", 12000);}
   
   
   
8. void draw() {
    
9.  background(0); 
   
10.   println(String,theMsg);  // < - This part
    
11. }
    
    
    
    

In summary: i could do with some guidance into using oscP5 to read a message on the wifi/tcp.



Thanks for reading this post, it is people like you that make this community so brilliant to learn from.



Kind regards,

Hi All,


I have a load of .jpg files I want to play back (in sequence at a certain fps) on a android devise.


What is the best way to animate these? (there are approx 200 files/frames that are on my PC)

Is the best way to produce a .gif? (If so, how is this done? searching this matter brings up a lot of rubbish, i was wondering what the best method is?)


I'm aware I can code these all in individually but I don't fancy that kerfuffle :)

I produced this animation in 'Pencil.'


Thanks for your time.

Hi All,

I am very new to this.


I have a Java based program that runs on my normal processing Java state.


I wish to put this on a android devise. I have all the installed stuff required. (I can run example processing programs without a problem, that is on the devise)


When i try to run my program onto android i get:

1. No library found for processing.net
2. Android SDK Tools Revision 20.0.3
3. Installed at C:\Program Files\Android\android-sdk
4. Project Type: Application
5. Project Target:   Android 2.3.3
6. API level:        10
7. Library dependencies:
8. No Libraries
9. ------------------
10. API<=15: Adding annotations.jar to the classpath.
11. Merging AndroidManifest files into one.
12. Manifest merger disabled. Using project manifest only.
13. No AIDL files to compile.
14. No RenderScript files to compile.
15. Generating resource IDs...
16. Generating BuildConfig class.
17. BUILD FAILED
18. C:\Program Files\Android\android-sdk\tools\ant\build.xml:679: The following error occurred while executing this line:
19. C:\Program Files\Android\android-sdk\tools\ant\build.xml:692: Compile failed; see the compiler error output for details.
20. Total time: 2 seconds

Does anyone know what I should do? To get my program on my android devise.


Many thanks.

Hi all,

I have processing set up as a client.

A GET is sent to my server.

Processing  then receives:

"R"
channel_1
channel_2


I can print these values in the processing monitor, but i cannot seem to use the values to determine a shape characteristic. Processing receives the values I am interested in, please see the println in my code.

I have had the shapes working before i implemented a GET command.

1. import processing.net.*;
   Client myClient;
   String inString;
   int dataIn;
   int serverreq = 1;
   int speed = 500;
   int  channel_1 = 0;
   int  channel_2 = 0;
   
   
   
   void setup()
   {
    
     size(500, 500);
     myClient = new Client(this, "192.168.0.6", 80);
    
   }
   
   
   
   void draw()
   {
     
      
       for(int i = 5; i>4; i++)
      
       {
      
           myClient.write('X');
     
           delay(speed);
     
           inString = myClient.readString();
   
     // if (myClient.available() > 0) {
          
         String[]data = split(inString, ",");
   
     //println(data[0]);
     //println(data[1]);
     //println(data[2]);}
    
          int[]intValues = int(data);
    
    
    if("R".equals(data[0]))
        {
       
      channel_1 = (int)intValues[1];  
      channel_2 = (int)intValues[2];  
   
   
   
     print(channel_1); 
     print(",");
     print(channel_2);
     println(",");
                                   // in the monitor it prints my data values as expected.
   
        }
      
    else
          {
      println("Frame error!");
            }
   
       }
    
   rect(100,400,100,-channel_1);    //
      rect(250,400,100,-channel_2);    //  << Darn graphs wont draw :(
   }
   
   

Hi all,

I am trying to achieve a arduino server that sends data to clients after a certain client message request.


My client sends a message GET to the server asking for some data (Processing sends this). As:

 [loop function here with delay]
  myClient.write("X");


I have arduino receiving this message, and it can be seen in the serial monitor with:

      char thisChar = client.read();

        Serial.println(thisChar);

The message comes out as:
X
X
X
etc


I am trying to apply a IF statement to the client.read(). - In arduino


For example:

if(thisChar = 'X'){
Serial.println("X received and recognised");
server.write("X recognised");


Essentially I do not have the basic knowledge to convert the client message into something arduino understands - and then can take actions on this.

If anyone could help me out in this - it would be much appreciated.

I imagine it wont be anything too crazy.


Many thanks.

Hi all.

I have two data inputs :

data[1]    (range 0-1024)
data[2]    (range 0-1024)



Simply I require to plot a simple bar graph of these.

So that I have two bars on the same axis showing the values from two analog channels.

I'm struggling to get started on this,

Thanks for your time.

Hi all,

I have a server churning out some values.

I wish to read the values, in processing.

I have been trying client.read - with no luck?

Can anyone suggest/guide me?

I can read my server data in teraterm with no problems.



Many thanks,


My server code is:



#include <SPI.h>
#include <WiFi.h>

char ssid[] = "---";
char pass[] = "---";
int status = WL_IDLE_STATUS;

int Analog0 = A0;
int Analog1 = A1;
int Analog2 = A2;
int Analog3 = A3;
int Analog4 = A4;
int Analog5 = A5;

int sensorValue0 = 0;
int sensorValue1 = 0;
int sensorValue2 = 0;
int sensorValue3 = 0;
int sensorValue4 = 0;
int sensorValue5 = 0;


WiFiServer server(80);

void setup() {
  // initialize serial:
  Serial.begin(9600);
  Serial.println("Attempting to connect to WPA network...");
  Serial.print("SSID: ");
  Serial.println(ssid);

  status = WiFi.begin(ssid, pass);
  if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while(true);

    server.begin();
  }
}

void loop() {
  // listen for incoming clients
  WiFiClient client = server.available();

     
    // to any clients connected to the server:
   
    sensorValue0 = analogRead(A0);
        sensorValue1 = analogRead(A1);
            sensorValue2 = analogRead(A2);
                sensorValue3 = analogRead(A3);
                    sensorValue4 = analogRead(A4);
                        sensorValue5 = analogRead(A5);
                       
   
   
    server.print(sensorValue0,DEC);
    server.print(",");
    server.print(sensorValue1,DEC);
  //  server.print(",");
  //  server.print(sensorValue2,DEC);
  //  server.print(",");
  //  server.print(sensorValue3,DEC);
  //  server.print(",");
   // server.print(sensorValue4,DEC);
  //  server.print(",");
   // server.print(sensorValue5,DEC);
    server.println(",");
   
   
    Serial.print(sensorValue0);
    Serial.print(",");
    Serial.print(sensorValue1);
   // Serial.print(",");
  //  Serial.print(sensorValue2);
  // Serial.print(",");
  //  Serial.print(sensorValue3);
   // Serial.print(",");
   // Serial.print(sensorValue4);
   // Serial.print(",");   
   // Serial.print(sensorValue5);
    Serial.println(",");

    delay(0);
  }

Hi,


I am new to networking in general.

I am receiving a data strand in this format. (I can control the format, for example i can change the denotation)

This strand of data is very simple and is of two ATD values, [1],[2],[1],[2]. etc



368,175,367,175,368,175,368,175,368,175,368,175,
etc


I want to create a simple bar graph of these two arrays.

How do i tell Processing that the first value is data[1], the second value is data[2], then the next is data[1].. and so on?



Thanks for reading this.

I appreciate that it is a nooby question.

Even if you could point me in the right direction - that would be great.
