Public bug reported: Hi,
I'm currently trying to debug why my Bluetooth Barcode scanner (emulating a keyboard) with a USB bluetooth dongle does not work anymore with my 18.04, can't connect it anoymore (it used to work at lease occasionally months ago.) It pairs, but can't be connected as a HID. One of the problems was that error message in /var/log/syslog: Connection ":1.182" is not allowed to add more match rules (increase limits in configuration file if required; max_match_rules_per_connection=2048) After adding <limit name="max_replies_per_connection">1024</limit> <limit name="max_match_rules_per_connection">2048</limit> to the busconfig struct in /etc/dbus-1/system.d/bluetooth.conf at least this error message vanished (while others persist, still does not work). However, this should be in /etc/dbus-1/system.d/bluetooth.conf as delivered from the package and not require the user to debug and change. regards ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: bluez 5.48-0ubuntu3.1 ProcVersionSignature: Ubuntu 4.15.0-50.54-generic 4.15.18 Uname: Linux 4.15.0-50-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 CurrentDesktop: XFCE Date: Sun May 26 14:37:28 2019 InstallationDate: Installed on 2018-06-09 (350 days ago) InstallationMedia: Lubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) InterestingModules: rfcomm bnep btusb bluetooth MachineType: Medion G24 ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-50-generic root=UUID=a3f06afa-8405-4064-8044-0a9e1b4c19c8 ro quiet splash vt.handoff=1 SourcePackage: bluez UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/12/2012 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: H61TIW08.111 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: H61H2-TI2 dmi.board.vendor: Medion dmi.board.version: 1.0 dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 3 dmi.chassis.vendor: Medion dmi.chassis.version: 1.0 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrH61TIW08.111:bd10/12/2012:svnMedion:pnG24:pvr1.0:rvnMedion:rnH61H2-TI2:rvr1.0:cvnMedion:ct3:cvr1.0: dmi.product.family: To be filled by O.E.M. dmi.product.name: G24 dmi.product.version: 1.0 dmi.sys.vendor: Medion hciconfig: hci0: Type: Primary Bus: USB BD Address: 00:1A:7D:DA:71:13 ACL MTU: 310:10 SCO MTU: 64:8 UP RUNNING PSCAN RX bytes:2128 acl:0 sco:0 events:126 errors:0 TX bytes:4712 acl:0 sco:0 commands:106 errors:0 mtime.conffile..etc.dbus-1.system.d.bluetooth.conf: 2019-05-26T14:29:51.468868 ** Affects: bluez (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic -- 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/1830537 Title: missing max_match_rules_per_connection Status in bluez package in Ubuntu: New Bug description: Hi, I'm currently trying to debug why my Bluetooth Barcode scanner (emulating a keyboard) with a USB bluetooth dongle does not work anymore with my 18.04, can't connect it anoymore (it used to work at lease occasionally months ago.)
