[PATCH BlueZ v1] obexd: Add system bus support for obexd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Damodar Reddy GangiReddy <quic_dgangire@xxxxxxxxxxx>

Currently obexd uses session bus.
Distros  where session bus is not supported and still obex profiles
are required in that case use system bus instead of session bus
which can be configured with new optional feature

Additional optional feature has been added to achieve this
with name --enable-use-systembus-for-obexd

steps to configure system bus
./configure --enable-use-systembus-for-obexd
