Hello, Someone tried to use MTKBabel with the Holux M-241 GPS datalogger with no success. The device is based on the MTK chip, but unfortunately the binary log data is not the one described on the Mediatek datasheets.
I made a quick check: first of all the serial port must be set to 38400 baud instead of 115200. But the real problem is with the data: latitude and longitude are stored as float (4 bytes) numbers instead of double (8 bytes), there is not a checksum between records, there are unknown data blocks. Due the lack of documentation I'm not able to add support for this device into MTKBabel. The guys at BT747 project [1] eventually succeded in supporting this device, let me know if someone has some documentation. Here you can find an hacked version of MTKBabel [2], which should read something out of the Holux. [1] http://bt747.wiki.sourceforge.net/ [2] http://www.rigacci.org/wiki/doku.php/doc/appunti/hardware/gps_logger_i_blue_747 I can easly add support for different serial port speed, bu I don't know if adding support for Holux is feasible for me (I don't have the hardware). Please, can someone also check the status of GPSBabel with MTK? My software was intended as a temporary solution waiting for GPSBabel guys. -- Niccolo Rigacci Firenze - Italy -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
