I'm having problems with my XBee Pros intended as the downlink for the Ardupilot. When I hook my Locosys 5hz GPS directly to the computer using the FTDI cable, I'm getting a 5hz update rate as seen in the attached file GPSFDI.txt
As soon as I introduce the XBees in the link, thus GPS--->Xbee (set at 38400) ----> XBee ->FTDI, the rate drops down to on NMEA sentence every few seconds or so as seen in the attached file GPSXbee.txt.
What am I doing wrong? I've separated the two XBees anywhere from a few feet to 10 meters apart, but with the same results. How can I get an acceptable transfer rate with the XBees?
