Solmeta GMAX (for Nikon cameras) Firmware Ver2.6 (20170429-Release)
The new firmware file name is ¡°GMAX_for_Nikon_Ver2.6_20170429-Release.dfu¡±
The Ver 2.6 is an upgrade firmware from Ver 2.5 (201605181107-Release). 
A professinal user named Bill and another user named Hendrik report to us that they find a bug at the same time:
1. On the log file the two sentences $GPRMC and $PTNTHPR have wrong checksums, so some software can not use these sentences.
We find there is a bug on these two sentences's checksums.
We upgrade and trouble shoot the bug.
So we release this version Ver2.6.
If you do not care the log files, you can keep in Ver 2.5, no other problem.

The new firmware file name is ¡°GMAX_for_Nikon_Ver2.5_201605181107-Release.dfu¡±

The Ver 2.5 is an upgrade firmware from Ver 2.3 (201602021739-Release). 
Some changes, improvements and fixes.
1.Fixed a problem regarding the compatibility of GMAX and Nikon D810.
( many thanks to great user named Mr. Bradford Glade in USA )
2.Improve the Timer release minimum interval time from 4 sec. to 3 sec. The improvement provides aerial photography user shooting interval as fast as possible. 
3.The air pressure unit changes to inHg instead of PSI. Also, user can use inHg unit to do ¡°Sea-Leavel Calibration¡± directly.
4.To support more application, the data format for information of D-GPS is masked into normal data format in the GMAS¡¯s log files. 

When doing the firmware upgrade, please read the information bellow thoroughly.
1.To do the firmware upgrade, please refer to the guide of GMAX_Firmware_upgrading_guide.pdf in the folder.
2.The tools program supports 32Bit Windows system. The best is Windows7 32bit.

If you use MAC OSX, you need to download ¡°DfuSe¡± burning chip tool and driver by yourself.  If you install the firmware and try to run the DfuSe Demo software, sometimes it might immediately fail with the following error:
 "The application was unable to start correctly (0xc0150002). Click OK to close the application."
In this case you determine that the software was depending on ¡°Visual Studio 2005 Service Pack 1 Redistributable Package MFC Security Update¡±. Once you install that you are able to run the software and can see the GMAX as a device to upgrade.

Hi,

After installation of driver downloaded from your site, I follow instruction but impossible to connect the GMAX Geotagger with the PC UBS.
I update the driver STM Device in DFU Mode directly in the windows device manager and update with this file and it¡¯s working, I can do my upgrade. Now I can use without problem GMAX with my Nikon D810.
