BlueZ-4.101 RFCOMM issue and missing daemons


I'm setting up BlueZ-4.101 to run on my 3.3 linux kernel. I've run into a few issues with development involving pairing with another device.

The first issue is RFCOMM. I'm trying to use the command
Code:
# rfcomm connect 0
Can't connect RFCOMM socket: Operation now in progress
to pair with a target bluetooth device. I can use hcitool inq and see the device, but am unable to connect using rfcomm.

After further inspection, I see that /dev/rfcomm0 (or any rfcomm node) does not exist after using the command
Code:
# rfcomm bind all
. I've looked through various threads and am unsure why this is.

This investigation led to me seeing that I am missing some bluetooth scripts that should possibly be running. I'm not quite sure if I should or should not have these scripts based on my kernel/bluez version. For example, the only daemon that I have is bluetoothd which I start on boot. I do not have any of the following scripts even installed:
  • bluetooth-agent
  • bluez-simple-agent
  • /etc/bluetooth/hcid.conf (not a script - but still missing)

To me, this feels like I have something possibly configured incorrectly in the kernel/filesystem. However, I've checked and made sure that I have full support for Bluetooth, including:

Kernel:
  • BT_RFCOMM_TTY
  • BT_RFCOMM
  • BT
  • BT_BNEP_PROTO_FILTER
  • BT_BNEP_MC_FILTER
  • BT_BNEP

Filesystem:
  • BR2_PACKAGE_BLUEZ_UTILS
  • BR2_PACKAGE_BLUEZ_UTILS_COMPAT

I've tried to solve this for days and could use a little guidance. If more information is needed let me know.

Relevant information:

/etc/bluetooth/rfcomm.conf:
Code:
#
# RFCOMM configuration file.
#

rfcomm0 {
        bind yes;
        device 30:21:XX:XX:XX:XX;
        channel 1;
        comment "speaker";
}
Configuration

Regarding the missing /etc/bluetooth/hcid.conf file, I see now that this thread addresses that. The other issues still persist however.

Updating with another log file, as I'm still having trouble but have more information.

Some things that I've noticed but am not sure what to think of:
  • /etc/bluetooth/input.conf - Does not exist, this seems ok to me as I don't have any defined inputs (other bt devices)
  • Failed to open RFKILL control device - This seems troubling, but selecting CONFIG_BT in kernel also selects RFKILL so I'm a bit confused
  • /etc/bluetooth/serial.conf 0 Does not exist. Unsure if this is important, searching online didn't reveal much
  • Unable to load keys to adapter_ops - Unsure why default keys need to be loaded, seems to be a misunderstanding on my end
  • I keep seeing dba as 00:00:00:00:00:00 throughout the log, this seems wrong to me, assuming dba = device bluetooth address

Audio support with bluez4.101

Hi,
I would like to know if you were able to get anything working on bluez4.101 since I am also exploring bluez4.101. I am particularly looking into audio streaming capabilities using bluez4.101.

I ended up doing a whole OS upgrade and using BlueZ 5.46 and kernel 4.12.0. Things are generally working well with that setup.
