Dell XPS 13 (9370) masalah Bluetooth

Saya memiliki masalah berikut dengan modul Bluetooth pada Dell XPS 13 (9370) saya yang baru dengan Ubuntu yang sudah diinstal.

Modul bluetooth dinonaktifkan karena beberapa alasan. Perangkat bluetooth (keyboard dan mouse) berhenti bekerja di tengah pekerjaan, indikator Bluetooth hilang dan modul juga hilang dalam rfkilldaftar.

Untuk membuatnya kembali berfungsi, saya harus mem-boot ulang mesin, mulai BIOS, nonaktifkan modul Bluetooth dan aktifkan kembali. Setelah itu, modul bluetooth tersedia lagi. Itu sangat menjengkelkan.

Syslog saya ketika ini terjadi:

Apr 11 12:25:48 visyu-albatross org.gnome.Terminal[2417]: ** (gnome-terminal-server:12197): WARNING **: Unable to set locale modifiers with XSetLocaleModifiers()

Saya sudah mencoba berbagai hal:

1. Menonaktifkan TLP dan menonaktifkan TLP untuk Bluetooth di /etc/default/tlp
2. Memperbarui BIOS ke versi 1.2.1
3. Mengatur baris ini ke modprobe untuk ath10k: echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
4. Memutakhirkan linux-firmwarepaket, seperti disebutkan di sini: https://www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debian

Tidak ada yang membantu sampai sekarang.

Sejauh yang saya bisa lihat, ini adalah perangkat keras berikut: QCA 6174 Killer Qualcomm / QCA 1535 Killer Qualcomm

Sebagian besar saya memiliki dua perangkat bluetooth ini dipasangkan dan terhubung:

• Keyboard Logitech K810
• Mouse Logitech MX Anywhere2

Saya memiliki masalah yang sama, dan saya pikir itu membaik dengan memperbarui firmware Bluetooth menggunakan file yang termasuk dalam driver Windows terbaru. MD5 saya:

sonic@sonic-XPS-13-9370:/lib/firmware/qca$ md5sum *usb*302*
067fb95e8501bad2683df07d23539e7d  nvm_usb_00000302.bin

86c377ab7b2c24cc12cea5e79f71d610  rampatch_usb_00000302.bin_orig

Omong-omong, solusi yang lebih mudah adalah mencabut kabel daya dan melakukan siklus penangguhan / melanjutkan.
Dan setidaknya milikku adalah Pembunuh 1435.

Pembaruan untuk jawaban Sven Killig untuk Dell XPS 9370 di Ubuntu 18.04:

Di utas lain ada laporan yang memperbarui ke kernel yang lebih baru (4,17 atau lebih tinggi) juga menyelesaikan masalah.

Untuk melakukan ini pada Ubuntu 18.04 jalankan perintah:, sudo apt install linux-generic-hwe-18.04lalu reboot.

Saya baru saja melakukan ini; jadi, jika tidak berhasil saya akan melaporkan kembali.

Saya juga dapat mengonfirmasi bahwa sebagai solusi penangguhan ( Fn+ End[🌙]) laptop kemudian membangunkannya dengan daya yang dicabut secara umum dapat diandalkan untuk mengaktifkan kembali fungsi WiFi dan Bluetooth.

Menemukan banyak solusi. Hanya satu yang berhasil! Perintah yang saya gunakan adalah

modprobe btusb && systemctl start bluetooth

Anda mungkin memerlukan izin root untuk itu.

Saya menemukannya di forum ini .

Seperti yang mungkin sudah Anda ketahui, bluetooth mati / hilang saat tidur. Latihan untuk itu adalah menambahkan skrip untuk mematikan bluetooth sebelum tidur dan hidup kembali setelah tidur.

Saya hanya akan menempelkan jawabannya .

Cukup letakkan skrip yang dapat dieksekusi dari nama apa pun di / lib / systemd / system-sleep /.

#!/bin/sh
if [ "$1" = "pre" ]; then
  systemctl stop bluetooth && rmmod btusb
elif [ "$1" = "post" ]; then
  modprobe btusb && systemctl start bluetooth
fi

Semoga berhasil juga untuk Anda!

Juga, hanya FYI, inilah info sistem saya.

Solusi yang diterima tidak bekerja untuk saya (atau setidaknya tidak bekerja secara terpisah). Ada kesalahan dmesgtentang hilangnya file firmware dengan nama yang sangat berbeda.

Saya menggunakan eoan (19.10) dan menemukan solusi di sini berdasarkan https://bbs.archlinux.org/viewtopic.php?id=198865 .

Tautan unduhan buruk sehingga saya mendapatkan file CAB dari https://drivers.softpedia.com/get/BLUETOOTH/Broadcom/Broadcom-Micro-size-USB-to-Bluetooth-Dongle-Driver-12011010-for-Windows- 81-64-bit.shtml . Anda harus cabextractmengekstraknya.

Maka saya perlu melakukannya

sudo hex2hcd BCM20702A1_001.002.014.1443.1572.hex -o /lib/firmware/brcm/BCM20702A1-0a5c-216f.hcd

dan mulai kembali ..

Solusi yang berhasil bagi saya: matikan dan matikan laptop, tunggu sebentar untuk memastikan, lalu nyalakan lagi.

Saya menjalankan ubuntu 17.10 btw, tetapi tidak ada bedanya :)
