Okay, that means we have a working bluetooth setup. Did you pair your
device?

Also make sure you have disabled modem-manager.

Actually "test-connman scan bluetooth" won't work. The only valid
arguments are "wifi" of "wimax". So returning an error is okay but it
could be done in a more user friendly way.

If you have paired your phone (e.g. using the bluetooth UI tool from
gnome or kde) and your phone supports PAN it should appear without any
additional steps.

The only device ConnMan maintains is your local ethernet device.

Check if your phone is paired and if it's supports PAN. E.g. the iPhone
is such a device. list-services will produce something like this:
[ /profile/default/bluetooth_00025b0322a0_90840db2c704 ]
IPv6.Configuration = { Method=off }
AutoConnect = false
Proxy.Configuration = { }
Name = Car IT 009
Nameservers = [ ]
Provider = { }
Favorite = true
Domains.Configuration = [ ]
State = idle
Proxy = { }
Nameservers.Configuration = [ ]
LoginRequired = false
IPv6 = { }
Domains = [ ]
Ethernet = { Method=auto }
Security = [ ]
IPv4.Configuration = { Method=dhcp }
Type = bluetooth
Immutable = false
IPv4 = { }

Dear Daniel,
Thanks for the query response. We followed your steps and we have further querie
s.
Issue:
Not able to successfully use the connman scripts to connect,disconnect,enable,di
sable for bluetooth.
Steps that are followed:
1) Pairing with the Bluetooth enabled device ( with PAN Support ) with Bluetooth
UI tool is working fine.
2) Could you please let us know the steps to follow to pair using BlueZ 4.94 scr
ipts without using Bluetooth UI tool. Because when we are creating the device th
rough the BlueZ 4.94 scripts, list-devices shows the "paired" property value as
0.
3) When we paired the device with Bluetooth UI tool and executed the list servic
es from connman and the output as follows:
[root@01HW087732 test]# ./list-services
[ /profile/default/bluetooth_001f81000250_18e7f4f25a5e ]
IPv6.Configuration = { }
AutoConnect = false
Proxy.Configuration = { }
Name = Krishnaji's iPhone
Nameservers = [ ]
Provider = { }
Favorite = false
Domains.Configuration = [ ]
State = idle
Proxy = { }
Nameservers.Configuration = [ ]
LoginRequired = false
IPv6 = { }
Domains = [ ]
Ethernet = { }
Security = [ ]
IPv4.Configuration = { }
Type = bluetooth
Immutable = false
IPv4 = { }
4) test-connman sevice paths are as follows
[root@01HW087732 test]# ./test-connman services
* Wired { ethernet_00142245bd5b_cable }
Krishnaji's iPhone { bluetooth_001f81000250_18e7f4f25a5e }
We are not able to connect to the Bluetooth service path and the output
as follows:
[root@01HW087732 test]# ./test-connman connect bluetooth_001f81000250_18
e7f4f25a5e
net.connman.Error.Failed: Input/output error
5) But we can Disable the bluetooth through test-connman disable.
[root@01HW087732 test]# ./test-connman disable bluetooth
( This command successfully diasabled the bluetooth service path. )
But after disabling, we tried to enable the bluetooth, the error is "Operatio
n Time Out"
[root@01HW087732 test]# ./test-connman enable bluetooth
Thanks and Regards,
Sree Gowri.
