Even with the patch applied by Intel, it does not increase the TPT because the UI always selects BASIC mode. Steps: 1. On the top right corner of the system's screen (system 1) click on the System Tray 2. Click on Bluetooth Settings, and turn Bluetooth ON 3. Using another system (system 2) with Ubuntu installed, turn on Bluetooth and pair with the system 1. 4. Confirm the Bluetooth PIN 5. Send Files via Bluetooth from system 1 to system 2 6. Send Files via Bluetooth from system 2 to system 1 Expected Result: File transfer via bluetooth have a fast transfer for small size files. Actual Result: File transfer via bluetooth to another fedora system too slow. Sample File transfer duration: sending - (8MB) 5min 18s sending - (12MB) 7min36s receiving - (8MB) 4min 8s receiving - (12MB) 5min 48s Remarks: > This issue was also observed in Ubuntu 18.04 OS > Launchpad issue: > https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1879438/ Reply at: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1879438/comments/5 ** Changed in: bluez Status: Unknown => Confirmed ** Changed in: bluez Importance: Unknown => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879438 Title: bluetooth file transfer via bluetooth UI is too slow To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1879438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
