Product: Drivers Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: Bluetooth Assignee: linux-bluetooth@vger.kernel.org Reporter: t.darcin10@gmail.com Regression: No Regression report: Intel 8265 Bluetooth (8087:0a2b) BLE connectivity regression observed after kernel upgrade. Environment: - Debian 13 (trixie) - Kernel: 6.12.86+deb13-amd64 - Previous working kernel: 6.1 (Debian 12) - Bluetooth driver: btusb - Device: Intel Dual Band Wireless-AC 8265 Problem: BLE hearing aid device becomes unusable at normal distance (~0.5=E2=80=931m= ). Device only works when placed directly on top of the computer. Classic Bluetooth devices (mouse, keyboard, phone audio) work normally. This indicates BLE-specific regression rather than general Bluetooth failur= e. Kernel logs: ---------------- iwlwifi 0000:3a:00.0: missed beacons exceeds threshold, but receiving data Bluetooth: hci0: HCI LE Coded PHY feature bit is set, but its usage is not supported ---------------- Observations: - Wi-Fi and Bluetooth share Intel 8265 module - Wi-Fi shows occasional missed beacon warnings - Bluetooth firmware loads correctly - No general HCI failure or device reset observed - Issue is reproducible and consistent Expected behavior: BLE devices (hearing aid) should operate normally as in kernel 6.1. Actual behavior: Severe BLE range degradation only affecting hearing aid device. Reproducibility: 100% Regression: Yes (worked on kernel 6.1, broken on 6.12) Likely affected area: btusb / Intel Bluetooth LE / PHY handling in kernel 6.12 --=20 You may reply to this email to add a comment.
