There has been a few issues caused by recent Glass upgrade to XE19.1.
My application suffers the same issue.
There seems to be other bugs caused by the same upgrade EyeGestures NOT working in 19.1
Is there a way we can disable the auto upgrade by google? My application will be used within firewall, any possibility to block certain IP or Port?
Any other recommendation will be appreciated.
Go to the Developer website (http://developers.google.com/glass) and navigate to Tools & Downloads / System and Kernel downloads (https://developers.google.com/glass/tools-downloads/system).
Follow the instructions to install a rooted boot loader for a specific version. Once you have rooted you will no longer receive automatic updates. The downside is that you will have violated your warrantee.
