It's much easier to search for and read text that isn't in an image. Also, on SO, we don't edit a solution into the question. Instead, we post it as an answer, so that the original asker (you) can check the box that this answered your question. –Teepeemm Nov 4 '15 at 16:52 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted I had to disable the plugin pnat in /etc/bluetooth/main.conf -> DisablePlugins=pnat.

When I use hcitool, I can discover the SmartTag device. But when I use gatttool, I cannot connect. It says "Host is down connection refused 111 (112)". Here are my commands: $ sudo hcitool lescan LE Scan ... BC:6A:29:AB:DE:2B (unknown) BC:6A:29:AB:DE:2B SensorTag Checking for bluetooth adapters on my RPi I get: $ hcitool dev Devices: hci0 5C:F3:70:60:E6:1B Then, when I use the gatttool like this, I get: $ sudo gatttool -i hci0 -b BC:6A:29:AB:DE:2B -I [ ][BC:6A:29:AB:DE:2B][LE]> When I type connect, I get this: [ ][BC:6A:29:AB:DE:2B][LE]> connect Connecting... connect error: Host is down (112) [ ][BC:6A:29:AB:DE:2B][LE]> I found some info on the web that said "Host is down" means that the bluetooth sensor is not in discoverable mode. But this is not correct as far as the SmartTag is concerned since I press the one button (side button) on the sensor that TI says to push to make it discoverable. And that same one is used by the hcitool lescan to find the device. There's also an android app that runs off a phone and it scans, connects, and reads the SmartTag sensor just fine when that same button is pressed. Does anyone know what the problem might be? Thank

Thats working now.https://bbs.archlinux.org/viewtopic.php?id=141698I followed the wiki but I cant capture/send audio streams to the headset - i get connection refused, so i asume that I am not connected.$ aplay -D btheadset mymp3.mp3 bt_audio_service_open: connect() failed: Connection refused (111) aplay: main:682: audio open error: Connection refused(I tried that with root permissions, too.)How does this work, do I need to connect to the headset although I am already paired. If so, how can I do this?I tried bluez-manager and after a while i got this connection attemt (which I cannot reproduce now)but when i entered "yes" nothing happenedbluez-simple-agent Agent registered Authorize (/org/bluez/719/hci0/dev_00_23_78_5C_00_A8, 0000111f-0000-1000-8000-00805f9b34fb) Authorize connection (yes/no): So is there another way to connect?Thanks in advance,Keen Last edited by keen90 (2012-05-19 07:17:59) Offline #2 2012-05-18 19:28:00 pigiron Member From: USA Registered: 2009-07-14 Posts: 137 Re: [SOLVED] bluetooth paired but not connected? First of all, aplay will only produce noise with a MP3 file. It wants a WAV file. But that's not the reason for the error.Bluetooth is a complicated beast, and the Bluez implementation is much more complicated... and using it without a GUI is even more difficult... so I admire your courage and tenacity... plus you try to provide details when asking for help. So good job all around.But...I was able to duplicate your "Connection refused (111)" error by reverting to the original /etc/bluetooth/audio.conf file.Did you miss the portion of the Arch Wiki on Bluetooth where it talked about the Enable flag for audio streams?https://wiki.archlinux.org/index.php/Bl … _streamingNot mentioned in the wiki is that you can enable all the Bluetooth audio services by using the following:Enable=Source,Sink,Headset,Gateway,Control,Socket,MediaBut it depends on how paranoid you are about security on which ones you enable. Also, anything on a non-commented Dis
