NAME
mtkbabel - Tool for managing GPS data loggers based on the MTK chip
SYNOPSIS
mtkbabel [-abcdEfhiIlmopRrstvwx]
DESCRIPTION
mtkbabel is a command line program to operate GPS data loggers based on the MediaTek MTK
chip. It was tested on the i-Blue 747, Qstarz BT-Q1000 and on the Holux M-241, it should
work also with other GPS devices based on the same chip.
The main features are:
- Command line interface
- Save data log in GPX and raw binary format
- If required retrieve all the data, also the old one being overlapped
- Change logging criteria: time, distance, speed
- Change log format
- START/STOP logging
- Set OVERLAP or STOP method on memory full
- Erase the internal memory
USAGE
In order to use mtkbabel, please follow these instructions:
1. Attach the GPS data logger device to your computer via USB.
2. Now you have to switch the GPS device (at least the i-Blue 747) into LOG or NAV mode,
otherwise the device will not be powered on, and no connection will be possible. Beware
that in NAV mode the device goes into sleep mode if not connected to any Bluetooth device.
3. In order to use mtkbabel you have to either be root (not recommended) and/or you must
have read/write permissions for the USB device file, usually /dev/ttyUSB0. This device
usually has permissions 'crw-rw---- 1 root dialout', so you can either add your user to
the dialout group (in this example) by doing
$ adduser USERNAME dialout
or (not recommended) make the device world-readable/-writable by doing:
$ chmod 666 /dev/ttyUSB0
Another option is to write a udev rules file to change the owner and permissions of
/dev/ttyUSB0 according to your requirements.
4. You can now run mtkbabel. For example, if you want to download the track log and the
list of waypoints you captured on the device, run:
$ mtkbabel -s 115200 -l off -f foo -w -t
The default speed of 115200 baud should work in most cases and you can omit it, for the
Holux M-241 you must use 38400 instead. This will turn off the autolog function, which is
always turned on when you switch on the device. The track log will be in the file
foo_trk.gpx, the waypoints in the file foo_wpt.gpx (both in GPX format). The file foo.bin
will contain the binary log file. Downloading the data from the GPS device can take
several minutes, depending on how much data has to be transferred.
In order to delete all data from the GPS device, run:
$ mtkbabel -s 115200 -E
OPTIONS
-a Read all the log memory (overlapped data).
-b filename.bin
Do not read data from a GPS device, but rather read a previously saved .bin file.
Ignore -f option.
-c Create a GPX file with both tracks and waypoints.
-d debug_level
Debug level: 0..7.
-E Erase data log memory.
-f Base name for saved files (.bin and .gpx). If you, for example, use -f gpslog,
mtkbabel will create files which are called gpslog.gpx, gpslog_trk.gpx,
gpslog_wpt.gpx and gpslog.bin.
-h Show a help text and exit.
-i Ignore some error conditions and try to extract as much data as possible from GPS.
-I Same as -i, but also write bad records into the GPX file.
-l {on|off}
Turn logging ON/OFF.
-m {stop|overlap}
Set STOP/OVERLAP recording method on memory full.
-o log_format
Enable or disable log fields (FIELD1,-FIELD2,...), available fields: UTC, VALID,
LATITUDE, LONGITUDE, HEIGHT, SPEED, HEADING, DSTA, DAGE, PDOP, HDOP, VDOP, NSAT,
SID, ELEVATION, AZIMUTH, SNR, RCR, MILLISECOND, DISTANCE.
-p port
Communication port, default: /dev/ttyUSB0.
-R Recover from disabled log: erase data and reset recording criteria.
-r time:distance:speed
Set logging criteria (zero to disable): every 0.10-9999999.90 seconds, every
0.10-9999999.90 meters, over 0.10-9999999.90 km/h. Not all the devices support such
wide ranges, more reasonable values are 1-999 seconds, 10-9999 meters and 10-999
km/h.
-s speed
Serial port speed, default 115200 baud.
-t Create a GPX file with tracks.
-v Show version information and exit.
-w Create a GPX file with waypoints.
-x Force reading Holux format. This is required to read-back the binary data produced
by some Holux devices, which do not embed into the data itself the Holux identifier
string.
