IrDA: does IAS query require some receiver socket?

Hi, NewLCers

I'm just starting with IrDA. Basically, I'd like to do some device discovery first. Then do some IAS queries to know more about remote devices. And last, try to connect to remote device. No data exchange required.

In the first phase, I'll start a "Ioctl discovery indication" (fr. Developer Library) socket on the secondary device (physically same as the primary device). When the secondary device is discovered, the primary device continues with IAS query. Now, is it necessary for the secondary device to start another listening socket for incoming queries? If not, is it safe to start another wait-for-connection socket for the third-phase connection request on the secondary device, right after the device is discovered?

Thanks in advance for any suggestion.
