I have a problem with connecting my Etrex GPS to my computer using the arduino FTDI chip as a serial to USB device.
I connect my Etrex with a max232 inbetween to my arduino TX and RX pins and i run a very simple sketch so that there is no interference with the chip:
This works and I can get different types of GPS data in the serial monitor.
But the problem is that I want to use a different program (like EasyGPS or GPSbabal) to upload and download waypoints and stuff from my GPS. But this doesn't work! Does anybody know why? The serial port works because I get data but I can't seem to send any to get other stuff like waypoints. I've tried it also with removing the Atmega chip and it's still the same (I still get data with the serial monitor but no connection with another program). Does somebody have an idea??
