I have this same problem on Xubunut 16.04. I cannot access rfcomm* except as root, despite the permissions: $ ls -al /dev/rfcomm0 crw-rw 1 root dialout 216, 0 Feb 18 13:58 /dev/rfcomm0 and my membership to dialout: $ id bob uid=1000(bob) gid=1000(bob) groups=1000(bob),4(adm),20(dialout),24(cdrom),27(sudo),30(dip),44(video),46(plugdev),115(lpadmin),131(sambashare) I would like to access rfcomm0 via putty, but it WILL only work with $ sudo putty Is there a workaround that can permanently fix this?

Writing a udev rule to ignore device by ModemManager worked for me:
/etc/udev/rules.d/55-bluetooth-drone-NoModem.rules
KERNEL=="rfcomm*", ATTR{address}=="xx:d3:xx:00:xx:xx",
ENV{ID_MM_DEVICE_IGNORE}="1"
And reloading rules:
sudo udevadm control --reload-rules
So I connect to device as root
sudo rfcomm connect hic0 XX:D3:XX:00:XX:XX
and then I am able to use it as regular user from dialout group

[Bug 1014992] Re: Ubuntu 12.04, i386, cannot use rfcomm as regular user. Permission denied.
Hello Christopher I've done some tests to find the first time this bug occur. I started the PC with different Ubuntu live CDs (every CD was a i386, desktop image). The last working distribution was 8.10 (Intrepid). The first time this bug appears was in the next version 9.04 (Jaunty). I've done this tests on several machines. The behaviour was the same on all machines so I think it's not hardware dependent. To make further tests I installed a *fresh* :-) Ubuntu 8.10 on a PC at my home. After the fresh install I've done sudo usermod -a -G dialout sysadmin and relogin. Then I tested it again: sysadmin@ritsch:~$ uname -a Linux ritsch 2.6.27-7-generic #1 SMP Fri Oct 24 06:42:44 UTC 2008 i686 GNU/Linux sysadmin@ritsch:~$ hcitool scan Scanning ... 00:12:6F:08:98:FF GEO LE-71 1 sysadmin@ritsch:~$ rfcomm connect 1 00:12:6F:08:98:FF<<<--- On first time I was asked for the pin code here Connected /dev/rfcomm1 to 00:12:6F:08:98:FF on channel 1 Press CTRL-C for hangup --->>> Everything OK with vanilla 8.10 Ubuntu In the next step I changed the apt package source in /etc/apt/sources.list (old-releases.ubuntu.com) and update the system to the latest available version for 8.10 and reboot. Then I repeat the test from above. The kernel version changed ... sysadmin@ritsch:~$ uname -a Linux ritsch 2.6.27-17-generic #1 SMP Fri Mar 12 03:09:00 UTC 2010 i686 GNU/Linux ... but the bug is not there and everything works fine. --->>> Everything OK with 8.10 Ubuntu with kernel 2.6.27-17 Now I decided to try to update the kernel to the same version as in the not working 9.04 ubuntu. The kernel version on my 9.04 CD is: ubuntu@ubuntu:~$ uname -a Linux ubuntu 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux The first try was to install the .deb packages from 9.04 on 8.10, but that don't work because some versions mismatch (wrong libc6-version ...). So I download the file linux-source-2.6.28_2.6.28-11.42_all.deb from https://launchpad.net/ubuntu/jaunty/i386/linux-source-2.6.28/2.6.28-11.42 and try to install it on the 8.10 ubuntu. To build the new kernel I installed all essential build tools, login as root and done the following steps: cd tar xjf linux-source-2.6.28.tar.bz2 cd linux-source-2.6.28 make mrproper cp /boot/config-2.6.27-17-generic .config make oldconfig <<< I answered all new questions with simply hit enter to use the default values make clean make deb-pkg ... some hours later ... sudo dpkg -i linux-2.6.28.9_2.6.28.9-1_i386.deb sudo dpkg -i linux-firmware-image_2.6.28.9-1_all.deb sudo update-initramfs -u -k 2.6.28.9 sudo update-grup The I reboot the PC and do the test again ... sysadmin@ritsch:~$ uname -a Linux ritsch 2.6.28.9 #1 SMP Fri Feb 7 00:16:26 CET 2014 i686 GNU/Linux The bug was not there! --->>> Everything OK with 8.10 Ubuntu with kernel 2.6.28.9 I was a little bit confused, that the kernel version is 2.6.28.9. I expected 2.6.28.11 because the package name was linux-source-2.6.28_2.6.28-11.42_all.deb ??? I'm not sure if this problem is only a kernel problem. Perhaps there are some other things (hotplug, udev ...) which cause this bug ? Please can you give me some hints hot to make further tests.

Burkhard Arenfeld, thank you for testing Trusty. >"Should I set the "kernel-bug-exists-upstream" flag now?" No, as this is strictly reserved for actually testing the latest upstream mainline kernel only. Testing Trusty is testing the downstream Ubuntu kernel, not mainline. However, the next step is to fully bisect from 8.04 to 12.04, to identify the offending commit.

[Bug 1014992] Re: Ubuntu 12.04, i386, cannot use rfcomm as regular user. Permission denied.
Hello again, I have done some tests with the latest development release of Ubuntu (trusty-desktop-i386.iso, downloaded on 13.01.2014). The bug is still there. Here the steps I've done to check it: - Boot ubuntu from CD (live cd, image from 13.01.2014) - Start the bluetooth applet - Open a terminal and enter. "hcitool scan" will list my bluetooth device correctly (MAC: 00:12:6F:08:98:FF) - Start the bluetooth applet from panel to add a new bluetooth device. In the "PIN-Option" screen I've checked fixed pin '1234'. On the first time a number is shown which I should enter on the bluetooth device. This doesn't work for me. My bluetooth device could not do this. The pairing failed after a few seconds. On the second try this number isn't shown and pairing is OK. (This behaviour is reproducable ;-). - Back into the terminal I entered "sudo usermod -a -G dialout ubuntu" to add the default user ubuntu to the dialout group and than login again to activate this setting with: "sudo login" with user "ubuntu" and empty password. - "rfcomm connect 1 00:12:6F:08:98:FF" fails with error "Can't open RFCOMM device: Permission denied" - "sudo rfcomm connect 1 00:12:6F:08:98:FF" works The tests with the latest upstream kernel available I have not done. This machine is on my work and I don't want to replace my 12.04LTS here. But if it's useful I can do it on my new PC at home.

Burkhard Arenfeld, thank you for updating your BIOS. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily- live/current/ . If the issue remains, please just make a comment to this. Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
