I'm trying to connect two xbee's pro s2 and make them communicate with each other in API Mode (further, I will use more end and router devices). Basically, I have a xbee coordinator plugged on my PC through digi adapter and I have other xbee connected to a PIC18f25. Right now I'm working on send and receive data from one to another and vice versa.
When I connect both on the usb adapter, the communication works just fine (I can send and receive data from/to both devices). However, when I try to work with the previous configuration, I find it impossible to get the data, which is sent from the coordinator, from the end device with the PIC. Here goes the data that I'm trying to send:
From Coord 2 EndD - 7E 00 13 10 01 00 13 A2 00 40 8D 5A 8B FF FE 00 00 48 65 6C 6C 6F 96
From EndD 2 Coord - 7E 00 13 10 01 00 00 00 00 00 00 00 00 FF FE 00 00 48 65 6C 6C 6F FD
I think it's usable to say that when I try to send the data from the PIC, through end device, to coordinator, it works.
I wonder if the problem relies on my code, which can be found below:
#include <18F25K20.h>
#device adc =10

byte var2=0x00;
long timeout;
void main() {
output_low(PIN_C5); // Turning on Xbee
delay_ms(10);
while(1) {
delay_ms(100);
output_high(PIN_C0); // TESTE
delay_ms(100);
output_low(PIN_C0);
timeout=0;
while(!kbhit()&&(++timeout<5000)) delay_us(5);
if(kbhit()){
output_high(PIN_C0);
delay_ms(10);
output_low(PIN_C0);
delay_ms(10);
output_high(PIN_C0);
delay_ms(10);
output_low(PIN_C0);
delay_ms(10);
output_high(PIN_C0);

output_low(PIN_C0);
var2 = getc();
delay_ms(1000);
}

putc(0xFD);*/
}
}
The program is supposed to blink a LED (PIN_C0) with 100 ms, and blink it faster if any data enter in the PIC. However it doesn't work as I planned and I have no clue why.
Any help will be appreciated.
Thank you all in advance,
Regards.
