HC-06 data into separate textboxes?

Hi rhyshagen448

I assume your hc-06 is transmitting to an Android device ?? if so then:

If you look here : https://www.element14.com/community/thread/44533/l/reading-arduino-csv-data-in-app-inventor

You will see a similar question from alacosta involving 5 data items, sent out as .csv, which was answered.

If you look at my blog, here: https://www.element14.com/community/people/neilk/blog/2015/02/02/mit-app-inventor-and-arduino-part-4--send-more-than-1-data-item-from-arduino-to-android-and-display

You will see several other potential solutions to your question.

Hope this helps

Hi neil, thanks for the response, Im quite new to app inventor so im not sure if what i am doing is right. This block code sends the temp and reaction both to the same label?

Hi Rhys - as far as your Arduino code is concerned, it's almost impossible to decipher from the screen shots you have included.

When posting code, it's much better to click "Use Advanced Editor" in the top right of the message window. This then allows you to click the >> symbol and then select Syntax Highlighting followed by c++. This gives the following sub-window:

You can then type or paste your code like this:

// Simulate 2 labelled data items and output to serial for Android demonstration  
  
const int pot = A0;  
  
void setup() {  
  pinMode(pot, INPUT);  
  Serial.begin(9600);  
}  
  
void loop() {  
  int potVal1 = analogRead(pot);  
  int potVal2 = potVal1/2;          // just to give a different value  
  Serial.print("LED State = " );  
  Serial.println(potVal1);  
  delay(600);         
  Serial.print("LDR Value = " );  
  Serial.println(potVal2);   
  delay(600);               
} 

As you will see from the above code, the effective output will be something like:

              LED = 135                    each line of data is followed by CR/LF

              LDR = 245

              LED = 178

              LDR = 465

And there will be a 600mS delay between each line of data. Your App Inventor code needs to read from the hc-06 more frequently than every 600mS, to avoid the input buffer of the Android device containing 2 lines of data.

The solution given in the second link I provided is, I think, superior to the above, because it doesn't rely on timing. If you study it, you will see that it assumes that the Arduino sends data in the form:

LED = 135,LDR = 245

and uses an App Inventor block which splits the incoming text into a list, using the , separator. Each item in the list is then independently accessible.

As a general rule, I would always start with a known, simple example and get that working first!! Then you can slowly convert it to your own requirements, retesting it at every stage and including lots of comments and Output to the serial monitor so you can understand what's happening when it stops working!

I hope this helps.
