Android Question recive and show multidata from bluetooth

poya10 · Jul 6, 2021

Hi, I want to take the information of the four temperature sensors as shown below and show them separately

1) Q23 , 2) W41 , 3) S-12 , 4) E21 ==> t1= 23 c , t2= 41 c , t3= -12 c , t4= 21 c

All this information is received together ( Q23W41S-12E21 ) and must be displayed separately
I know how to receive data via Bluetooth, I have trouble separating data.

B4X:

Dim s As String = "1) Q23 , 2) W41 , 3) S-12 , 4) E21"
Dim m As Matcher = Regex.Matcher("\d\)\s([\w\-]+)", s)
Do While m.Find
    Log(m.Group(1))
Loop

Thanks, can you tell me how you found this pattern?
Does my input (Q23W41S-12E21) work properly with this pattern?

No. I now see that I misread your post and thought that you need to parse a different pattern. Your post is a bit confusing.

Sorry, the Arduino board actually sends information from 4 sensors (or any data) in a string, my goal is to parse this string.
For example, I want to get the value of the four variables as follows from arduino

Arduino Side:

float ST1,ST2,ST3,ST4;

void setup(){
    Serial.begin(9600);
    
    ST1=12;
    ST2=25;
    ST3=-10;
    ST4=19.23;
}

void loop(){
    
    Serial.print("Q");
    Serial.print(ST1);
    Serial.print("W");
    Serial.print(ST2);
    Serial.print("E");
    Serial.print(ST3);
    Serial.print("R");
    Serial.println(ST4);
    
    delay(200);
}

// Serial output: Q12W25E-10R19.23

Now, this serial output is received exactly on Android, the value of Q must be inserted in place of sensor one, the value of W in place of sensor two, the value of E in place of sensor three, and the value of R in place of sensor four. (I want the information of these four sensors to be seen in the Android application)

Why waste your time with Arduino IDE? Switch to B4R and use B4RSerializator to send whatever you like.
