XBee Communication Problem : uP & PC

Postby khairul » Sun Mar 17, 2013 10:52 am

Hai, i have problem to communicate XBee S2 between uP & PC..

Note
*****
When i refer to XBee means i use XBee with SKXBEE Module

What i have Done
*********************
1) I have configure the Source & Destination address for both XBee.
2) I also have test the communication between 2 XBee using X-CTU and it work fine. (If i type "A" in X-CTU XBee#1, X-CTU XBee#2 will display "A")

The Problem
**************
1) When i connect XBee#2 to PIC and program it to transmit data to X-CTU XBee#1 nothing display at the X-CTU.
2) The LED X_RX and X_TX blinking rapidly so i thought the data actually transmitted.

Maybe your microcontroller code. Try first wired TX-RX from SKXBEE and microcontroller.
or show your clear photo of your hardware.

Check the connection between PIC and XBee.

Also, verify the PIC is working or not by connecting it to computer.

En.Shahrul
+++++++++
1) I have check the connection. The XBee_TX is connected to uP_RX and XBee_RX is connected to uP_TX...
2) I also have check the communication between XBee using X-CTU software and it work fine.. (It can communicate : See Attachment )

3) Refer to attachment 1, i configure the XBee based on tutorial at UTube
4) Refer to attachment 2, i think that only XBee#1(COM19) can transmit data and XBee#2(COM20) can only received.. Pleased verify.

5) I have look tutorial and Coding from Cytron, i want to use comment "ATMY1111" but i always get "ERROR", anyone have idea what the problem. (Refer to Attachment 3)

Mr.Robosang
+++++++++++
1) I have connect my PIC with Laptop using UART to USB converter (from Cytron), i have code it to send data and monitor it using Hyperterminal and everything work fine.

For All
++++++
1) Here my programming if anyone one to view it.

void ON_LINE_MODE(void)
{
int i;

LCD_CLR();
LCD_WRITE(0, " ON LINE MODE");

while(1)
{
LEDG = 1;
LEDR = 0;
for(i=0;i<=10;i++)
{
UART_SEND(50);
DELAY(5000);
}
}
}
//======================================
// PARTIAL OF UART LIBRARY
//======================================
#define RX_PIN PORTCbits.RC7
#define TX_PIN LATCbits.LATC6


void INIT_UART(void)
{
TRISCbits.TRISC7 = 1; // Set RC7 as Input
TRISCbits.TRISC6 = 0; // Set RC6 as Output

TXSTA=0b00100100;
RCSTA=0b10010000;
PIE1bits.RCIE = 0;
IPR1bits.RCIP = 1;
SPBRG=64; //Fosc = 10MHz | SPBRG = 64 | Baud = 9600

}
void UART_SEND(unsigned char data) //function to send out a byte via uart
{
while(PIR1bits.TXIF==0); //wait for previous data to finish send out
TXREG=data; //send new data
}

Assalamulaikum & peace to all

I have found the problem, The problem is XBee#1 only transmit data while XBee#2 only received data.. So anyone have idea how to make both XBee can transmit and received. I think the problem about the configuration especially the part like ATTACHMENT 3.

Make ATMY and ATDL same number.

In that case, you did not swap the SKXBee to verify it is bi-directional :)

BTW, you are using Series 2 right? It is not the same as series 1, do you know that?

I think cytron did a tutorial on how to configure series 2 XBee, you should check that out.

hi,

i have the same problem before...my xbee1 cannot detect what my xbee2 is transmitting ..i follow all the instruction from cytron tutorial...u know what i did? i restore all the data back to original ( Xbee )..then i just set he PAN ID only ( both must be set same number....the others is in default setting... it works realy2 well.. i can communicate from my pc via xbee to my arduino :)

im using XBEE S2..
