Holux M-1000C protocol doesn't seem to work

Hello!

For a while I wasn't figuring out what happened a while ago (between 2.x.1704 and 2.x.1887) which simply made gps data transfer not working with my Holux M-1000C, but yesterday I've been determined to look around the menus for new features which may have broken it and yes, there's a new device protocol called "Holux M-1000C", which was autoselected.

And it doesn't work.

Selecting old "Holux" (first option) just works.

Holux GR245 exports wrong elevation data (-48m MSL)

My GR-245 is working fine, but elevation is always around -47.8 to -47.9 m MSL. That can't be true.

The real altitude and altitude difference for tracks is displayed in the device, so I know it DOES log elevation data.

Any ideas?


No multiple Tracks in GPX + converting GPX to Google-Maps-HTML

Hi,

I am happily using bt747 with my Holux m-241 logger for quite a while now.
Since I just startet using bt747 more often I have the following three questions / feature requests:

1.: When I use the Holux m-241 .bin file (containing several tracks) as input and convert it to a GPX then the GPX-file contains only a single big track. The several tracks are combined to one big one.
Is there a way to conserve the division into several tracks in the GPX file?


Holux M-1000C and Holux GPSport 245

Holux decided to break compatibility with the Holux M-241 and they implemented for fairly mysterious reasons a slightly different log format and new commands in their serial protocol, while not supporting some of the Holux M-241 commands.

BT747 has improved support for these devices now (1.68.24+). To properly decode the log files, you need to set the device type to 'Holux GR245' (next to the convert button).

The serial protocol is under implementation by 'Robert'. Due to the extensive changes this protocol will be available in 2.X versions only. In the mean time, most of the commands continue to work. It may be that the reliability of the standard erase command is not very good for the Holux M-1000C, but it still works and may require a power cycle to connect with BT747 again.

For a description in French of the Holux GPSport 245, see xens's page.
