Why rename? To more easily understand and

identify your device.

Change Pin / Password: AT+PIN1234\r\n

Why change pin? For security purposes

WARNING: Remember to connect the Resistor as shown below to

avoid damage of Bluetooth devices

Before we proceed further... Note down your App-Link module new name

AT+NAME__________\r\n

Note down your App-Link module new PIN (4 bytes)

AT+PIN__________\r\n

Tips: Magnet Code commands

ends with \r\n

ASCII Code 0x0D = \r =cariage return

ASCII Code 0x0A = \n = new line



Steps to Rename + Change Password

#include <SoftwareSerial.h> // initialize software serial library

SoftwareSerial mySerial(10, 11); // RX, TX

// pin 11 as arduino TX pin10 as arduino RX

// Bluetooth RX connect TX(pin11),

//Bluetooth TX connect RX(pin10)

void setup() {

Serial.begin(9600); // set data speed 9600 bps

pinMode(9,OUTPUT); //set pin9 as output digitalWrite(9,HIGH); // initialize pin 9 as HIGH

Serial.println("Enter AT commands:"); // Serial Monitor should display “Enter AT //commands” mySerial.begin(9600); //set data speed =9600 } void loop() {

// Coding below enable user to run AT-command using software serial

if (mySerial.available())

Serial.write(mySerial.read());

if (Serial.available())

mySerial.write(Serial.read()); }

Connect circuit as shown below

if (data == '1') // if data received „1‟

{

// do task 1

}

else if (data == '2') //if data received „2‟

{

// do task 2

}

}

}



3.7(b) Receive Magnet Code data in String data type void setup()

Serial.begin(9600); // Set data speed =9600 bps

Serial.flush(); //clear serial monitor

}

void loop()

{

String input = ""; // clear the string every time loop finished

// Get the number of bytes (Strings) available for reading from the serial port

// To receive Strings data, we use “while “in serial available function

while (Serial.available() > 0)

{

input += (char) Serial.read(); // Read the Strings

delay(5); // Delay for 5 ms so the next char has time to be received

if (input == "FWD") // if input received string data “FWD”

{

// do task 1

}

else if (input == "STP") // if input received string data”STP”

Chapter 15 Database Toolbox (optional add on)

Database toolbox is used to read and write data from Excel file (.xls).

15.1 Database toolbox command list Following are available commands in this toolbox:


1 xls_reffil<filename>\r\n This command will open an xls file as an operating file to

read or write. File taken from the „File Path‟ set by the

User, e.g. „xls_reffil<abc >„ will open / create abc.xls to

read or write data.

Note:

a. User do not need to type the extension .xls in the file

name.

b. Each time „xls_reffil<filename>„ open a new file, the

existing file (if any) will be automatically closed.

c. If the filename does not exist, it will automatically create

a new file with an .xls format.

d. Select sheet1 as the operating sheet in default.

e. Select cell at row1 column1 of sheet1 as the starting

coordinate in default.

2 xls_refshe<sheet

name>\r\n

After an.xls file is open, the selected default sheet is

sheet1. However, user can change the operating sheet to

other sheets.

e.g. „xls_refshe<sheet2>„ will open / create sheet2 in file

User wish to.

Note:

a. Cell row1 column1 of the sheet is selected as the

starting coordinate in default.

b. If the sheet name does not exist, it will auto create a



new sheet with the given sheet name.

3 xls_refy<row>\r\n

This command will set the row coordinate in the operating

xls file for data saving or reading purpose.

E.g. With an original cursor at A1, the current cursor

coordinate will be set to A3 upon receiving „xls_refy<3>„.

4 xls_refx<column>\r\n This command will set the column coordinate in the

operating xls file for data saving or reading purpose.

E.g. With an original cursor at A1, the current cursor

coordinate will be set to C1 upon receiving [xls_refx<C>„.

the previous column (-1).

E.g.1. With an original coordinate at C3, the coordinate

becomes B3 upon receiving „xls_prex‟.

9 xls_addy<row>\r\n

This command will find an empty cell in the row identified

by the user, and then set the current y coordinate to that of

the empty cell.

E.g. If the current cursor coordinate is A1 and the

operating sheet at row 12 has already 3 columns of data

(at column A, B, C), the value of the cursor column will be

set to D upon receiving „xls_addy<12>„. Consequently, the

cursor coordinate will be D12.



10 xls_addx<column>\r\n This command will find an empty cell in the column

identified by the user, and then set the current x coordinate

to that of the empty cell.

E.g. If the current cursor coordinate is A1 and the

operating sheet at column C has already 3 columns of data

(at column 1, 2, 3), the value of the cursor row will be set

to 4 upon receiving „xls_addy<C>„. Consequently, the

cursor coordinate will be C4.

11 xls_finy<row#text>\r\n

This command will find the text required by the User in a

specific row.

If the text is found, the current coordinate will be set to be

the coordinate of the text cell.

E.g. If the current cursor coordinate is A1 and the B6 cell

has a text with the content „Hello‟.

After receiving „xls_finy<6#hello>„, it will find „Hello‟ in row

6.

If the text is found, it will send <XF1> to the connected

device, else it will send <XF0>.

At the same time, if the text is found, app will set B6 as the

current coordinate. Else, if the text is not found, it will

maintain the cursor position at A1.

12 xls_finx<column#text>\r\n This command will find text required by the User in a

specific column.

If the text is found, the current coordinate will be set to be

the coordinate of the text cell.

E.g. If the current cursor coordinate is A1 and the B6 cell

has a text with the content „Hello‟.

After receiving „xls_finx<B#hello>„, it will find „Hello‟ in

column B.

If the text is found, it will send <XF1> to the connected

device, else it will send <XF0>.

At the same time, if the text is found, app will set B6 as the

current coordinate. Else, if the text is not found, it will

maintain the cursor position at A1.



13 xls_toty<row>\r\n

This command will find the total filled cell in a specific row.

The total value in the specific row will be sent to the

connected device with 5 digits.
