Using PA revision prior to removal of socket api, issue happens with bluez just after removal of socket api there, but not with bluez just prior to that removal. So I pretty sure that this is regression in new media api ether in PA or in bluez. After exam I have very soon I look at the source code, to understand where the issue is coming from. Meanwhile I will be glad if you explain conceptually what SEP is. Meanwhile it looks to me as sort of IO channel, but I didn't dug deeper yet. Best regards, Maxim Levitsky
