Plugable BlueTooth adapter dissappears after disconnecting then reconnecting mobile phone on Raspberry Pi under Raspbian


#1

Hi!

I’m using the Plugable BlueTooth adapter with a Raspberry Pi Model 2 B. I’ve built a wireless audio system which accept audio from a bluetooth connected phone and streams it out to wireless speakers using a special USB soundcard. Everything works well unless I disconect the phone and then try to reconnect the same phone again. Here’s what that looks like when connected with bluetootctl;

pi@raspberrypi ~ $ sudo bluetoothctl
[NEW] Controller 5C:F3:70:6A:03:D0 BlueBerry [default]
[NEW] Device B4:3A:28:08:F7:9A Shaws Phone
[NEW] Device 84:55:A5:F9:7D:5D Katys Phone
[CHG] Device B4:3A:28:08:F7:9A Connected: yes
[CHG] Device B4:3A:28:08:F7:9A Connected: no
[CHG] Device B4:3A:28:08:F7:9A Connected: yes
[DEL] Controller 5C:F3:70:6A:03:D0 BlueBerry [default]

Immediately after reconnecting the adapter seems to get deleted? I then have to reboot to connect again. Any idea what’s going on here or what I can do to further debug this issue?

Many thanks,

Shaw

Hi Shaw,

Thank you for posting your question here.

I haven’t experienced this issue, so I’m going to do some testing here with and see if I can reproduce anything like it.

I’ll post anything I discover here.

Thanks!

Great stuff cheers. If there’s anything you’de like me to run here, give me a shout. I should probably mention I was using Raspbian and I was connecting to a Samsung Galaxy S5.

Many thanks,

Shaw.

Hi Shaw,

Thank you for checking back about this.

I’m sorry, but I haven’t had much chance to work on this, but I am working on it today.

Could you possible tell me which bluetooth-related packages you have installed on your pi?

Thanks!

David

Yup- I’m new to Linux so bare with me! I think I just have BlueZ which I’m using to stream music from my phone to the raspberry- I then pipe this out a USB soundcard.

Hi Shaw,
Actually, that’s a pretty sophisticated application. I’m asking, because I’m not getting bluetoothctl to work on my pi to test your issue.

Bluetooth has been weird on the pi recently. One question: When did you start using this pi. I’m wondering if it is an earlier version than the version of Raspbian on my pi.

I built the whole image about 3 weeks ago maybe? I did a sudo rpi-update, sudo apt-get update and sudo apt-get upgrade so it should have been the most latest stuff.

Here is the guide I followed actually! https://www.raspberrypi.org/forums/vi… There are also some posts from me to the author towards the end of the thread trying to diagnose this issue!
