Re: [Bluez-devel] About concurrency sdp_connect

[Fabrizio Guglielmino <guglielmino@infitsrl.com>]

Are You sure it's hardware restriction?
sdp_connect internally use the socket abstaction to create a l2cap =

socket and make a
connection with standard connect.
In old threads there is a discussion about actual software limitation of =

l2cap layer to make simultaneous
connection so I think the problem in sdp_connect is the same.....
