This evening I upgrade all of my Mitras to 1.10 and then decided to try the WiFi module upgrade too. I have never done this upgrade before but the instructions seemed simple enough. All lights were at firmware 6219. On my first light I used WiFi-Update-Tool.exe and selected the start option. It went through the process and and then I rebooted the light. Now all options under communication is off/blank and firmware is 0. I then switched my LX7 to slave mode and selected the blank chip and reprogram filesystem with the same results. I am not sure what I did wrong but I did not attempt to upgrade the WiFi on my other lights.
