USB interface of Mobile Phone with i2Control

Hello,

I will use for a mobil phone app a i2Control KNX driver and the serial port RS232.

It would be for application to a wheelchair for a person with disabilities.

Is it posible to install on a mobile phone androïd Galaxy S4 (for example), a virtual serial port to the USB port using a port emulation driver RS232 (as is done a PC) ?
And use it with i2control ?

Best regards,
Patrick
