Ublox GPS Configuration for Tau Labs FC
The current code does not include initialization strings to configure the GPS on each start-up. Therefore "manual" configuration is required in order to get the GPS working properly with TL. There are two ways to configure GPS for navigation.
The configuration file can be found. configuration file According to PUG398 "you are welcome to try this ubx 115k file to see if it works. Just remember after writing it change baud to 115k in ucenter and write it again."
1 Download and install [U-Center](http://www.u-blox.com/en/evaluation-tools-a-software/u-center/u-center.html)
2 Obtain a USB-Serial Converter FTDI, CP2102 will both work. (cp2102 is suggested since the recent FTDI driver change has casued a lot of trouble) This one from HobbyKing should work just fine Micro SATA Cable - USB 2.0 to TTL UART 6PIN Module Serial Converter CP2102 (the advantage the HK one is it has both 3.3v and 5v. you will be able to use it on any device)
3 Connect GPS to Converter
CP2102 ---- GPS
TX ---- RX
RX ---- TX
GND ---- GND
5v/3.3v ---- 5v/3.3v
(Be cautious about the voltage. Using 5v to power 3.3v GPS could cause damage)
4 Connect U-center to USB
In U-center
Enable Receiver>Autobaudrate (this option will help you auto detecting GPS baud rate if you do not know. Usually GPS is default at 9600/38400)
Choose your CP2102 ComPort in Receiver>Port
Open a Packet Console in View>Packet Console (or F6) (this help you to quick check if there is message coming from GPS)
5 Upload Downloaded Configuration File
Open Tools>GPS Configuration..
Open the downloaded configuration file
Check "Store Configuration intoBBR/Flash(non-volatile memory) (might not work for some older Ublox those do not have non-volatile memory)
Click "File >> GPS"
Unplug and re-plug in USB, Repeat 4 and 5 one more time to make sure everything is right.
