[PATCH 2/5] Move bluetooth utils from hfp.c to bluetooth.c

Gustavo F. Padovan gustavo at padovan.org
Tue Jun 8 00:43:57 PDT 2010


The new Bluetooth plugin will be responsible for handle DBus for the
Bluetooth profiles implemented by oFono. Each Bluetooth profile can
register callbacks to create a modem, remove all modems and set alias. The
idea is to have here soon code the handle Bluetooth Agent stuff too.
