dbus error while trying to enable hfp connection with smartphone

dbus error while trying to enable hfp connection with smartphone

[Robyn Minkler]

[-- Attachment #1: Type: text/plain, Size: 1156 bytes --]

I'm trying to get ofono, telepathy-ring and empathy set up so that I can
make and receive calls on my fedora 16 laptop. 

The list-modems script shows my phone, but I get a dbus error when I try
to run enable-modems. More information below. 

Does anyone have any suggestions about how I might debug this?

This is with:
dbus 1.4.10
ofono 1.3

./list-modems
[ /hfp/889FFAEA6A1B_78471DBB098C ]
    Name = Nexus S
    Powered = 0
    Lockdown = 0
    Interfaces = 
    Online = 0
    Features = 

./enable-modem

export OFONO_AT_DEBUG=1 and run ofono with -d option

Generally two things can go wrong:

- The bluetooth link could not be established for some reason.  e.g. the
your adapter is off, the remote device is off, stale pairing setup, etc.
 Use hcidump utility from bluez to debug this.

- The Handsfree SLC handshake could not be established.  The AT command
logs from oFono would help us diagnose that...

Hi Denis,

ofonod is throwing this error when I run enable-modem:

ofonod[17676]: plugins/hfp_hf.c:hfp_connect_reply() Connect reply:

Is this helpful?

Sounds like your BlueZ is not configured properly.  Try adding
Enable=Gateway to the [General] section of your /etc/bluetooth/audio.conf.
