I've got Nokia BH-105 headset, that I want to use with my PC.I can pair, but cannot connect to BH-105:[bluetooth]# connect 00:1C:EF:CA:B3:D0Attempting to connect to 00:1C:EF:CA:B3:D0[CHG] Device 00:1C:EF:CA:B3:D0 Connected: yesFailed to connect: org.bluez.Error.NotAvailable[CHG] Device 00:1C:EF:CA:B3:D0 Connected: noArchlinux wiki states, that BH-104 is tested to work with bluez4. It seems to me that both BH-104 and BH-105 are similar devices.As far as I understand HFP/HSP are not supported by bluez5 anymore. At the same time BH-105 does not support A2DP. HFP/HSP are supported by bluez4.I tried to install earlier version of bluez, but it cannot be found:qeeet@WorldEarth-PC:~$ sudo apt-get install bluez=4.99-2E: Version '4.99-2' for 'bluez' was not foundHow do I downgrade bluez to any 4.x version?UPDATE:I did everything as described here https://wiki.debian.org/StableUpdates and it doesn't work. I get this message:qeeet@qeeet-PC:~$ sudo apt-get update[lots_of_text]Reading package lists... Doneqeeet@qeeet-PC:~$ sudo apt-get -t wheezy install bluezReading package lists...
