gant - console based ANT+ information retrieval client for Garmin GPS products
gant [ OPTIONS ]
is a small command-line utility to retrieve information (sports
tracks, etc.) from Garmin GPS products over the wireless ANT/ANT+ protocols.
Currently supported devices are the Forerunner 405.
- -a authfile
- Provide authfile (default ~/.gant).
- -f name
- Assign a name to the ANT device. (default garmin)
- -d devno
- ttyUSB devno Device no. (default 0)
- -i id
- ID for pairing (default random)
- -m mydev
- (default 0)
- -D level
- Reset the device
- Do not write auth file
- Do not pair
- Show command line options.
Put 405 in pairing mode gant -f paul -a auth405
This gives your garmin a name of "paul" and an auth file of
"auth405" The 405 will ask you if you wish to pair with
"paul". Obviously you might want to use a different name :)
Download with: gant -nza auth405 > output
or -Dnza if you want lots of debug output
It doesn't seem to be very reliable at starting the download and I haven't
investigated why yet. So, if it doesn't start downloading press ctrl-c and try
again. I find it helps to take the watch out of power save mode.
If you've already downloaded the data, then you'll need to set "force
send" to yes on the watch.
Compare output with .TCX file produce by windows ANT Agent.
HOWTO USE gant
1. plugin your ANT+ stick 2. the system will load the kernel module
"cp210x" 3. to find out what ttyUSB device is used run
# dmesg|grep "cp210x
[...] cp210x 3-1:1.0: cp210x converter
[...] usb 3-1: cp210x converter now attached
In this case you have to use the optione "-d 3". If it is ttyUSB0 then
you don't need the -d option because 0 is the default 4. put the watch into
paring mode (menu -> configuration -> ANT+ ->
computer -> pairing on) 5. pair the computer with the watch
("mywatch" as name for the watch and
the file "auth405" as an authorization file which will be created)
# gant -d 3 -f mywatch -a auth405
6. download saved tracks from the watch
# gant -d 3 -f mywatch -nza auth405
You get the possible options with
# gant -h
To convert the downloaded TCX file (e.g. 2011-07-22-123456.tcx) you can use
# gpsbabel -t -i gtrnctr -f
2011-07-22-123456.tcx -o gpx -F 2011-07-22-123456.gpx

Wireless ANT communications happens over a USB2ANT dongle. Under Linux the
dongle is driven by cp210x
kernel module, and presented to user-space
as a USB serial port, /dev/ttyUSBxxx
is an integer.
The dongle is typically carrying the USB vendor id/product id pair of
0fcf/1004 or 0fcf/1008. Recent Linux systems employ udev
device nodes and permissions, thus appropriate
- Kernel driver module for USB2ANT dongle.
- Serial device created for dongle.
- Default authentication file.
