Hi,

I was hoping to use a BGT-31 with the GPS Speed Talker app so I could hear my speed while windsurfing. However, I discovered that all bluetooth functions are not available in the settings menu anymore! I know that they were there when I got the unit because I played around with it, but apparently, they got lost when upgrading the firmware. I tried re-installing the older (V1.3) firmware from the Locosys support site, but that did not restore the bluetooth menu options.

This is a bit of a bummer, because the GT-31 is more accurate than the GPS in the Android phone that I am using. Hearing the speed while sailing is a great thing for fine-tuning stance etc., and the BGT-31 would be perfect. I tried contacting Tom Chalko using the form on his web site, but got no response.

Any suggestions would be very welcome. Otherwise, I'd say: do not update the firmware on a new BGT-31!

you are sure you didn't flash it with GT-31 firmware?

There is only one firmware version (1.3B1015)  on the Locosys support site that is for both GT-31 and BGT-31, see http://www.locosystech.com/support.php?zln=en&DL=1&model=GT-31/BGT-31. All other web references, including this site (http://www.gps-speedsurfing.com/default.aspx?mnu=item&item=GTx), also indicate that the same firmware is for both the GT31 and the BGT31.

Chalko's update instructions do not specifically mention the BGT-31. The version from his page (1.4B0803T) installs and works fine on the BGT31, except that it removes the bluetooth-related menu items in the settings (and thereby effectively removes the bluetooth functionality). I think a warning in his update instructions, and on the instructions here on this site, would be warranted.

Is there any solution to this problem so far? I also lost the bluetooth functionality due to this update (1.4B0803T). Is it possible to roll back to any earlyer version to restor bluetooth?
