HC-05

[Osama Mohammed]

Please help me
I am using HC-05 Bluetooth module in my project ,I want to send data like numbers and some words to an andriod mobile phone, but HC-05 doesn’t send anything ,the wiring and code are correct though ,HC-0C is paired and connected well to my android device , but the data are not transferred , have anyone encountered the same problem !? or anyone who have worked on HC-05 maybe he could tell me how to use it maybe I did something wrong.

 

This is a simple code to send a and E serially 

 <reg51.h>

msDelay (unsigned int);

void main(void){
TMOD=0x20;
TH1=-3; 
SCON=0x50;
TR1=1; 

while (1) {
SBUF=”a”;
while (TI==0); 
TI=0;
msDelay(5000);
SBUF=”E”;
while (TI==0); 
TI=0;
msDelay(5000);

}
}

msDelay(unsigned int itime)
{
unsigned int i,j;
for(i=0;i<=itime;i++)
for(j=0;j<=100;j++);

}

check for baud rate setting (in the code) with that of Bluetooth Module.
