Android Open Accessory simultaneous connection

Question

I'm developing an AOA application. And i wonder if it's possible to maintain several simultaneous connections with AOA? Is it possible? Or only one application can use AOA in a time?

While using AOA the android handset(or tablet) functions as USB device and the accessory as USB host. One USB device can only connect with one USB host at a time, therefore, supporting several simultaneous connections using AOA through your application is ruled out.

The question asked literally concerns multiple applications, not necessarily multiple accessories. – Chris Stratton Feb 08 '14 at 06:12

Only one application can use AOA in a time.

Other app can communication with the AOA app.
