we have to send the 10 digit phone number from matlab to arduino and then to gsm for sending a message. but the arduino is not getting the phone number from matlab. the program of matlab and arduino is attached herewith.
matlab code for the given purpose is:
function varargout = sms(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @sms_OpeningFcn, ...
'gui_OutputFcn', @sms_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
% --- Executes just before sms is made visible.
function sms_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = sms_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;
global arduino; % initiating arduino as variable
try
arduino = serial('COM4','BaudRate',9600); % Start Serial communication with arduino at port 12 with baudrate 57600
fopen(arduino);
catch e
obj = instrfind; % execute when there is an error
fclose(obj);
delete(obj); % delete object
i=0;
arduino = serial('COM4','BaudRate',9600); % recreate arduino variable
fopen(arduino);
end
function num_Callback(hObject, eventdata, handles)
A = str2double(get(hObject,'String'));
% --- Executes on button press in sms.
function sms_Callback(hObject, eventdata, handles)
global arduino
fprintf(arduino,'@');
fprintf(arduino,A);
gui of matlab and arduino code is given in the attachments
