Cannot read data from XBee S1

d2rk

Hi,

I have QuickStart Board with XBee S1 (+ XBee Explorer Regulated) that receives commands from PC with XBee S1. The problem is I can send data from QuickStart board but cannot receive anything back, while PC client transmits and receives everything correctly.

Connections of QuickStartBoard and XBee S1:

• P27 <-> DOUT
• P28 <-> DIN

#include <stdio.h>
#include <stdlib.h>
#include <propeller.h>

int main() {
  char cmd;
  FILE* xbee_dev = fopen("SSER:9600, 28, 27", "r+");
  setvbuf(xbee_dev, NULL, _IONBF, 0);   // no buffering
  xbee_dev->_flag &= ~_IOCOOKED;
  waitcnt(50*(CLKFREQ/1000)+CNT);
  fputs("OK", xbee_dev);
  while (1) {
    if ((cmd = fgetc(xbee_dev)) > 0) {
      printf("Echo: %d\n", cmd);
    }
  }
  fclose(xbee_dev);
  return 0;
}

Any suggestions?

Thanks.

I've tried the same scheme, but with DemoBoard and everything start working as it should (I was using pins P6 and P7). Any guesses why it doesn't work with QuickStart board?

Sorry, my mistake. Just missed with J1 pins and actual propeller chip pins. Closed.
