Weird respond while trying to test RSSI respond time

Using Arduino Programming Questions

If you don't have much time, you can just read blue part :slight_smile:

I am trying to get RSSI value from HC05 and Arduino UNO for time, and I finally got RSSI :slight_smile:

But the case is, it is very hard to get,
(I plug off the Arduino, plug off 5 v pin, then plug on arduino, press the button on the HC05 while plugging in 5v pin again, and pull my hand from the button to get AT command mode; send at+init and at+inq commands[I have to press the button while sending at+ing code) to finally RSSI code :/)
I have this code and it is working

#include <SoftwareSerial.h>
SoftwareSerial BTSerial(10, 11);



char c = ' ';
boolean NL = true;


void setup() {
 Serial.begin(38400);
 BTSerial.begin(38400);
}

void loop()
{


  if (BTSerial.available())
  {
    c = BTSerial.read();
    Serial.write(c);
  }

  if (Serial.available())
  {
    c = Serial.read();
    BTSerial.write(c);

   if (NL) {
      Serial.print(">");
      NL = false;
    }
    Serial.write(c);
    if (c == 10) {
      NL = true;
    } 
  }
}

I need it automatic and continuous. So; firstly, I though that

#include <SoftwareSerial.h>
SoftwareSerial BTSerial(10, 11);



char c = ' ';
String command="at+init";
String command3="at+inqm=1,1,48";
String command2="at+inq";
boolean NL = true;


void setup() {
 Serial.begin(38400);
 BTSerial.begin(38400);

BTSerial.println(command);
 if (BTSerial.available())
  {
    c = BTSerial.read();
    Serial.write(c);
  }
BTSerial.println(command3);
 if (BTSerial.available())
  {
    c = BTSerial.read();
    Serial.write(c);


}
}
void loop()
{
  
BTSerial.println(command2);

  
  if (BTSerial.available())
  {
    c = BTSerial.read();
    Serial.write(c);
  }

 
  if (Serial.available())
  {
    c = Serial.read();
    BTSerial.write(c);

   
   if (NL) {
      Serial.print(">");
      NL = false;
    }
    Serial.write(c);
    if (c == 10) {
      NL = true;
    } 
  }
}

did not work :confused:

Then I though it might be because some timing case and that entering AT mode technique(Basically I though code works at wrong times)

So, I decided that maybe a system which would send at+inq command at every, for example, 30 seconds would work.

I though a parallel loop which works as a timer would do the job. After some googling, I learned double loop just does not work.

Then, I learned there is something called "timer". I checked it, but seemed a little complicated, so I looked trough reference to find something alternative.

I found millis() function and an example code. I planned to make a code which sends commands based on that function, like if(3000<millis()<4000) something...

But the case is, I don't know how much it takes to get one RSSI value. So I built an experiment code by inserting example code to my working one

#include <SoftwareSerial.h>
SoftwareSerial BTSerial(10, 11);

unsigned long time;

char c = ' ';
boolean NL = true;


void setup() {
 Serial.begin(38400);
 BTSerial.begin(38400);
}

void loop()
{


  if (BTSerial.available())
  {
    c = BTSerial.read();
    Serial.write(c);
       time = millis();
  //prints time since program started
  Serial.println(time);
  delay(500);
  }


  if (Serial.available())
  {
    c = Serial.read();
    BTSerial.write(c);


   if (NL) {
      Serial.print(">");
      NL = false;
    }
    Serial.write(c);
    if (c == 10) {
      NL = true;
    } 
  }

}

However, when I started with entering at+state? command, the respond is

And I have no idea what to do next :confused:

EDİT= Colours

you can just read yellow part

No, I can't. Only a dumbass would expect people to be able to read yellow on white.

And I have no idea what to do next

Stop with the anonymous printing. You have NO idea what you are printing. Is any given character part of the bluetooth output OR a digit from printing millis()'s output?

You have NO idea. So, don't print crap that way.

The response to "at+state?" is:
STATE:INITIALIZED
OK
Is that not the response you were expecting?

I fixed colours, thanks.

So, there is no way to manually find the problem while we are not sure which "Serial" does it?

Then, I will first stop getting Serial respond from the HC05 and test it again. :slight_smile:

Actually I am trying to catch INITIALIZING to use at+inq command, and I actually reached it without the timer.

I am trying to get also a time value with incoming RSSI value to make sure about times.
