Solmeta GMAX-EOS V1.6 Release 20180917 for Canon cameras



The Ver 1.6 is an upgrade firmware version from Ver1.5. This Ver1.6 is a very important upgrade for EOS 80D camera(Maybe also for EOS800D)

The firmware file name is "GMAX-EOS V1.6 (Without bluetooth function) Release 20180917.dfu"

The below is the key points:

1/ We finally got the bug by helping of an American user. We find the key of the problem on EOS80D hotshoe communication link. We turned the program parameters and now make it stable for EOS80D and 800D hotshoe link. Before Ver1.6, you sometime find the hotshoe link broken and stoped after you shoot some pictures. And now it works well and stable.

2/ GMAX-EOS LCD menu display version of GPS module "SAT" has been optimized in order to compatible with our 2nd supplier's product. Because we found the 2nd supplier's GPS module was not shown version info on firmware Ver1.5 and before.



Be sure, Do NOT run this version on Solmeta "GMAX-EOS2" product with bluetooth remoter function hardware (Device).
