Isn't it technically possible for the master to send small amount of
BNEP data to PANUs in parked mode using the PSB logical channel? The
PANU would of course have to shift into connected mode before replying.

The above would allow the system to support a BNEP layer broadcast (e.g.
ARP) to all PANUs attached to the GN (i.e those in connected and parked mode).

Isn't it better for e.g. the link manager to do this since the BNEP layer
can only see BNEP traffic, but the link manager can also see SCO and ACL
traffic.

Thanks for your explaination.
