Issue persists with current LibO 6.3.1.2 and most likely due to the fact that the bluetooth stack on linux (bluez) has changed in the past years and impress has not cought up.
Problem is now more visible due to the startup tooltips in Impress 6.3.x which explicitly introduce the impress remote functionality inviting the users to test it. Goes like: start Impress -> see tooltip -> get interested -> download and install phone app -> try -> fail -> get disappointed and remove phone app. Because the phone based remote is one of those little things with a great wow factor that makes LibO really shine out and amaze people when used in front of an audience, it would really be great if the functionality could be restored. It is literally a little big thing helping getting a foot in the door. In fact, I suppose that if one could also add a "spotlight" and "zoom" functionality in it (in addition to the pointer) and the ability to use the phone accelerometers for moving the pointer (in place of the finger on the screen) it would make LibO a serious contender for all those coveting the "Logitech spotlight" that is currently the hot thing in presentations selling for over $100.

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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
