How can i print multiple sensor data on app in separately

I have made one App in mit app inventor 2. In which i have used 5 sensor and bluetooth module. I am sending multiple sensor data on app but it gives error bad list arguments.I have trouble in receiving data on separate text. would you please explain me how can i receive data on separately. 

please reply as soon as possible.

See the posts on using Delimiters in the Arduino/Bluetooth section of this FAQ:

Q&A for Arduino and Bluetooth

For more specific help, include in your post attachments with:

Your Arduino sketch (.ino)

Downloaded blocks images 

Screen shots of your Bluetooth component options in the Designer

a .aia export

Screen shots of run time behavior

 I am Attaching below my arduino code file , block images and screenshot of run time behaviour. would you please explain me how can i remove this error. 

code

#include <SoftwareSerial.h>

#include <DHT.h>

#define DHTPIN 7      // what pin we're connected to

#define DHTTYPE DHT22   // DHT 22  (AM2302)

DHT dht(DHTPIN, DHTTYPE); // Initialize DHT sensor for normal 16mhz Arduino

SoftwareSerial BTserial(4, 3); // RX | TX

float t;

float h;

char Temp_data;

char Hum_data;

char buffer [10];

float Temperature ()

{

 // Read temperature as Celsius (the default)

  t = dht.readTemperature();

  return (t);

  

 }

float Humidity ()

 {

  //Read data and store it to variables hum and temp

  h = dht.readHumidity();

  return (h);

 }  

 void setup() 

{

   Serial.begin(9600);

   BTserial.begin(9600);

  // put your setup code here, to run once:

pinMode (DHTPIN, OUTPUT); // Temperature pin set as output

}

void loop() 

{

  // put your main code here, to run repeatedly:

  int temp = Temperature ();

  int hum = Humidity ();

  sprintf (buffer, "%d ,%d", temp, hum);

  Serial.println(buffer);

  BTserial.println (buffer);

  //BTserial.print ("temperature =");

  BTserial.print (temp);

  BTserial.print ("C");

  delay(1000);

 // BTserial.print ("humidity =");  

  BTserial.print (hum);  

  BTserial.print ("%");

  delay (1000);

}

You did not supply a .aia export, so diagnosis will be limited.

You are sending three different types of message from your Arduino:

1. a comma separated list of temp and humidity, ending in LF

2. temperature readings ending in "C"

3. humidity readings ending in "%"

You need to test each incoming message to see if it contains a comma, or a "C", or a "%",

so you can decide which label to put it into.

If the incoming messages contains a comma, only then should you split it into a list.

Don't make any assumptions about how many items will be on the list.

Test if length of list (list) > 1 before asking for item 2.

Test if length of list (list) > 2 before asking for item 3.

etc.

Also, you should not need 2 clocks, 1 will work for you if you do it right.

See this link for how to use println() to send separate messages,

and for how to receive them one at a time using a delimiter.

Hello Sir, I am not getting separate data in app. How can i differ it. would you please send me correct arduino code and block in my app

I am sending my app .aia file. File attach below.
