= NMEA =
From software version 2.02a (!FlightCtrl/NaviCtrl) we can also send the '''NMEA''' signal from the UBlox GPS. <<BR>>
If you use a camera with integrated data logging you can use this data to save the position data n the pictures.
You can get the NMEA signal on the contacts '''PIN9''' (TxD) + '''PIN7''' (GND) of your serial output (!FlightCtrl V3) or Debug port (!NaviCtrl).
The data records '''RMC & GGA''' are sent with '' 57600 Baud '' '(default) / TTL (5V).

##----------------------------------------------------------------------------
To send the NMEA signal via PIN9 you '''__need__''' a microSD card ~-(max. 2GB/FAT16)-~ in your !FlightCtrl V3 / !NaviCtrl.
On this microSD card you find the file "SETTINGS.INI". You can open and change this file via an editor. <<BR>>
The output interval of the NMEA signal is set with the parameter ''NMEA_INTERVAL''.
# NMEA Output interval in ms (0 = disabled) <<BR>>
NMEA_INTERVAL = 0
By default, the output is disabled (NMEA_INTERVAL = 0)<<BR>>
If you need a signal e.g. every 500ms set here a "500" (NMEA_INTERVAL = 500)
The output is 57600 baud. From SW-Version 2.20 you can change the output speed <<BR>>
under "__# Baudrate for the PC-UART__".
<<BR>>
'''IMPORTANT:''' <<BR>>
If you change the baud in your SETTINGS.INI all data will be send in this speed !!! <<BR>>
So if you use e.g. a wireless connection between Copter <-> PC you also have to change here the speed!
~-
INFO: <<BR>>
If there is no Parameter "__# NMEA Output interval in ms__" in your SETTINGS.INI, delete the "SETTINGS.ini" on your microSD card. After you power up the copter the Software on your copter will create a new "SETTINGS.INI" with the needed parameters.

If you set a ''NMEA_INTERVAL'' in your SETTINGS.INI, you can check the output data in the terminal window of your !KopterTool.
For this "click" the button '''[-> !NaviCtrl]''' in your !KopterTool and then the <<BR>>
button '''[Firmware update & Terminal]''' to open the terminal window. <<BR>>
Here you should now see some data like this: <<BR>>
