The bug is still there as of LibO 7.3.x. Up in comment 12 (https://bugs.documentfoundation.org/show_bug.cgi?id=120663#c12) there is a nice analysis of the underlying problem why the remote cannot work.
Established that, I think that most users go used to the fact that the remote functionality does not work in linux. Personally, I have uninstalled the android app on the phone so I do not have an unfortunate reminder about it. In fact, the real issue is probably the advertisement of a functionality that is not there. For the time being I suggest disabling the remote-via-bluetooth functionality in linux and closing the bug by simply saying that the remote via bluetooth cannot be supported on linux where there are evidently issues that span other software pieces such as the bluetooth stack and pulse audio. To the best of my understanding, these involve the hijacking of the default rfcomm channel by pulse audio before it even needs it and the lack of a standard approach to let other applications find a free channel to use and advertise it to their counterparts. Alternatively (but I would not consider this a good solution), the configuration options could be enhanced to add the possibility to choose a bluetooth channel in libreoffice and in the mobile phone application, so that the user can manually work around the fact that the predefined channel is locked by some other application. As a final point, note that even if the remote-via-wifi may seem a good alternative, in fact in most cases it is practically useless. In most cases, presentations will not be given at a place where you control the network, but at sites with site-provided wifi, such as universities, schools, conference places, business sites, etc. All these locations tend to have wifi deployments that block stuff on the ports used by impress remote. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1798400 Title: [upstream] Regression: cannot use impress remote over bluetooth with ubuntu bionic Status in LibreOffice: Confirmed Status in bluez package in Ubuntu: Confirmed Status in libreoffice package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in libreoffice package in Fedora: Unknown Bug description: Trying to use the impress remote (https://wiki.documentfoundation.org/Impress_Remote) over bluetooth with libreoffice over ubuntu bionic fails. The handset errors out that it cannot connect with Libreoffice on the computer even if the bluetooth adapter on the handset and on the computer are correctly paired. This does not seem to be an issue in the Libreoffice or in the impress remote code: - I have tested also past LibO versions - The Impress remote codebase has not changed recently This used to work on the same hardware (headset and laptop) with ubuntu 16.04. Hence the issue seems to be in a regression in the ubuntu bluetooth stack. To replicate: 1) Install Libreoffice on Ubuntu bionic (either from the ubuntu repo or with the deb packages from the document fundation) 2) Assure that your computer has bluetooth 3) Install impress remote on an android handset (either from the play store of via fdroid) 4) Assure that "remote control" is enabled in impress Tools>Options>Impress>General 5) Pair the bluetooth adapters in the laptop and in the computer 6) Open a presentation on the laptop 7) Open the remote on the handset, got to the bluetooth pane see the computer there, touch it 8) See the impress remote erroring out Most likely you will also get a bluetooth error on dmesg RFCOMM server failed for LibreOffice Impress Remote: rfcomm_bind: Address already in use (98) Same issue was reported for fedora ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: bluez 5.48-0ubuntu3.1 ProcVersionSignature: Ubuntu 4.15.0-36.39-generic 4.15.18 Uname: Linux 4.15.0-36-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.4 Architecture: amd64 CurrentDesktop: KDE Date: Wed Oct 17 16:57:29 2018 EcryptfsInUse: Yes InstallationDate: Installed on 2013-12-12 (1769 days ago) InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) InterestingModules: rfcomm bnep btusb bluetooth MachineType: Notebook W740SU ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-36-generic root=/dev/mapper/zagar_ssd--vg-root ro quiet splash resume=/dev/zagar_ssd-vg/swap_1 acpi_backlight=vendor vt.handoff=1 SourcePackage: bluez UpgradeStatus: Upgraded to bionic on 2018-06-08 (131 days ago) dmi.bios.date: 10/02/2013 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 4.6.5 dmi.board.asset.tag: Tag 12345 dmi.board.name: W740SU dmi.board.vendor: Notebook dmi.board.version: Not Applicable dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: Notebook dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr4.6.5:bd10/02/2013:svnNotebook:pnW740SU:pvrNotApplicable:rvnNotebook:rnW740SU:rvrNotApplicable:cvnNotebook:ct9:cvrN/A: dmi.product.family: Not Applicable dmi.product.name: W740SU dmi.product.version: Not Applicable dmi.sys.vendor: Notebook hciconfig: hci0: Type: Primary Bus: USB BD Address: 00:C2:C6:1A:28:71 ACL MTU: 310:10 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:245088 acl:15156 sco:0 events:1266 errors:0 TX bytes:15571 acl:402 sco:1 commands:131 errors:0 To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1798400/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
