How to setup the Xbee Modules for usage with QCopter
1. Download the X-CTU software from digi: http://www.digi.com/support/productdetl.jsp?pid=4624&osvid=0&tp=5&tp2=0
2. Try different Baud rates until the test/query succeeds. Probably 57600 or 9600 will do the trick.
3. Under Modem Configuration set the following
- Channel on both XBees to the same number. (I'm using 13)
- Destination Address High to 0
- Destination Address Low to 0xFA11
- 16-bit Source Address to 0xFA11
- Interface Data Rate to 57600
- API model enabled
After writing the settings to the device, you should adapt the Baud rate under PC settings and also enable API mode there. Otherwise you can not communicate with the XBee anymore.
