Further debugged it to check dbus and bluez service
dbus is running and service file is also present
root@am335x-evm:~# cat /usr/share/dbus-1/system-services/org.bluez.service
[D-BUS Service]
Name=org.bluez
Exec=/bin/false
User=root
SystemdService=dbus-org.bluez.service
root@am335x-evm:~# cat /etc/dbus-1/system.d/bluetooth.conf
<!-- This configuration file specifies the required security policies
for Bluetooth core daemon to work. -->
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration
1.0//EN"
"<a href="http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd";>
www.freedesktop.org/.../busconfig.dtd"></a>
<busconfig>
<!-- ../system.conf have denied everything, so we just punch some holes
-->
<policy user="root">
<allow own="org.bluez"/>
<allow send_destination="org.bluez"/>
<allow send_interface="org.bluez.Agent"/>
<allow send_interface="org.bluez.PasskeyAgent"/>
</policy>
<policy context="default">
<allow own="org.bluez"/>
<allow send_destination="org.bluez"/>
<allow send_interface="org.bluez.Agent"/>
</policy>
</busconfig>
When I run bluetoothd, I can see org.bluez in dbus list
root@am335x-evm:~# dbus-send --system --dest=org.freedesktop.DBus
--type=method_call --print-reply /org/freedesktop/DBus
org.freedesktop.DBus.ListNames
method return sender=org.freedesktop.DBus -> dest=:1.4 reply_serial=2
array [
string "org.freedesktop.DBus"
string ":1.4"
string ":1.0"
string "org.bluez"
]
But when I query default adapter, I don't get a response
root@am335x-evm:~# dbus-send --system --print-reply --dest=org.bluez /
org.bluez.Manager.ListAdapters
method return sender=:1.0 -> dest=:1.5 reply_serial=2
array [
]
What's missing to get it working ? Any help is appreciated
Thanks
Ankur
