Bluetooth-Terminal as Serial Monitor

#1

Hi, I´m from Germany, 15 years old and a fan of your really cool robot-kits.

How can I make the following sketch give me an output on a Terminalprogram like Putty on windows or Blueterm on android. It should be just a test to get the thing work. In the long run I want to pass data through bluetooth - for example from the TestUltrasonicSensor-Sketch to a bluetooth-device… The Serial Monitor Part works flawless.

#include <Makeblock.h>
#include <SoftwareSerial.h>
#include <Arduino.h>
#include <Wire.h> 

MeBluetooth bluetooth(PORT_4);

int cnt = 0;    // Counter
void setup()

{   Serial.begin(9600);   // Initialization
    bluetooth.begin(9600); // Initialization bluetooth
}
void loop()
{   cnt++;
Serial.print("Hello BB from Arduino! Counter:"); //print message
Serial.println(cnt);    // print counter
delay(1000);   // wait 1 sec
}

I´m a abolute beginner. I already searched the internet for an explanation, but wasn´t succesful. I guess because of the Baseshield, Bluetooth isn´t just working like a normal serial port? How can i adapt the sketch to make it act like one, or even use Serial-functions like “print, println, etc.”.
Thanks in advance for any suggesttions.

#include <Makeblock.h>
#include <SoftwareSerial.h>
#include <Arduino.h>
#include <Wire.h> 

MeBluetooth bluetooth(PORT_4);

int cnt = 0;    // Counter
void setup()

{   
    bluetooth.begin(9600); // Initialization bluetooth
}
void loop()
{   cnt++;
  bluetooth.write("Hello BB from Arduino! Counter:"); //print message
  bluetooth.write(cnt);    // print counter
delay(1000);   // wait 1 sec
}

You may try this code. bluetooth is just a normal serial device.

Thanks for your answer. You are right, it should, but it doesn´t.

sketch_dec19a.ino: In function 'void loop()':
sketch_dec19a:16: error: invalid conversion from 'const char*' to 'uint8_t'
sketch_dec19a:16: error: initializing argument 1 of 'size_t MeSerial::write(uint8_t)'

If I cut out this part:

//bluetooth.write("Hello BB from Arduino! Counter:"); //print message

…and only focus on:

bluetooth.write(cnt);    // print counter

Output on Putty (Terminalprogramm) looks like this:

123456789:;<=>?@AB ...

Which is more than Igot before, but not what the sketch is suppossed to do. Anybody, any ideas what is going on? Thanks in advance.

hi, carlmorlok.
the library code has been updated on Github. https://github.com/Makeblock-official/Makeblock-Library

now it can support “print” string like the native serial.

#5 
#include <Makeblock.h>
#include <SoftwareSerial.h>
#include <Arduino.h>
#include <Wire.h> 

MeBluetooth bluetooth(PORT_4);

int cnt = 0;    // Counter
void setup()

{   
    bluetooth.begin(9600); // Initialization bluetooth
}
void loop()
{   cnt++;
  bluetooth.print("You guys from makeblock are awesome: "); //print message
  bluetooth.println(cnt);    // print counter
delay(1000);   // wait 1 sec
}

Now it works like a charm. Special Thanks to Huluwa,indream and not to forget xeecos for fixing the MeSerial and SoftSerial.

Just ordered the Advanced Kit Gold from www.exp-tech.de one of your distributors in Germany.

Tried to upload a screen capture from Putty, but it doesn´t let me. Anyway thanks a lot.

I’m trying to do this and cannot get it to show on putty for windows. what settings do you have for everything?

This is an, ahem, very big necropost.
But, anywho, what do you mean by “cannot get it to show”? That’s pretty broad, haha.
