Android : Unable to Discover ZWAVE device in Homegenie

I have STB based on A20 soc and Running Android 4.2 on it.

I'm using homegenie for homeautomation and I'm facing problem in Discovery of ZWAVE device.

For configration of ZWAVE device I follow this steps,

I go into 'Configure' section, then I click 'ZWave Interface Options' and then click to Enable, and select ttyS5, and click Discovery. Nothing really is happens. A blank page pops up. We used ADB to check on A20 STB shell, I see no program opened /dev/ttyS5.

I have also tried to click on 'Add Node', it just is indicating Time Out.

Another issues is that after you make any changes, and return then back, it will not save.

Any Suggestion ?
