Hi
I just received a f/w update this morning and have been testing it on a few devices (Nexus 5 and Samsung Galaxy S4). It seems to be working fine on these and solves disconnection issues with Android 4.4+.
Please go to: https://sites.google.com/a/nikura.com/miracast/download
and download 1_CRM200_V3.0_RC2.rar
You will find the instructions inside the rar file, however the english is quite poor!
Installing the drivers is the harder part (however given that you're using a Nexus, understand what version of Android you're using and know your Windows version - I expect you'll find this easy 🙂 )
After you have installed the drivers:
ii) Run the batch tool - RXBatchTool.exe (found inside the Batchtool folder)
iii) Load the firmware (where it says FW path) CR-M200_cloudnetgo_3.0-rc2_20131218_update
iv) Hold the button on the device and connect it via USB to your computer
v) The batchtool will show "connected devices 1-2) with a green light
vi) Let go of the button
vii) Click restore
viii) If everything is ok, the update will take 2-3 minutes and will show 100% success
Any problems, please feel free to contact me on xxxxx will be glad to help at any time.
Kind regards
