Di laptop saya menggunakan debian 9 dan bluetooth berfungsi dengan baik.
Saya telah memperbarui debian ke versi 10, setelah itu bluetooth tidak berfungsi.
Saya tidak begitu baik di linux. Bisakah Anda membantu saya?

Jawaban yang Diterima:
Pesan log menunjukkan sistem sedang mencari Intel BlueTooth (ibt ) file firmware, pertama di /lib/firmware/intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq , lalu di /lib/firmware/intel/ibt-hw-37.7.bseq , tetapi tidak menemukan salah satu versi file firmware.
Buka intel sub-direktori linux-firmware git tree, temukan file firmware yang benar di sana, dan klik "plain" di akhir baris dengan nama file untuk mengunduhnya. Kemudian tempatkan file ke dalam /lib/firmware/intel direktori, dan reboot (atau bongkar &muat ulang modul kernel yang sesuai). Metode ini bekerja untuk semua distribusi Linux dan juga untuk firmware yang belum dikemas oleh distribusi.
Atau, pastikan Anda mengaktifkan bagian non-bebas dari repositori paket Debian (lihat pertanyaan ini di ServerFault untuk instruksi jika perlu), dan pastikan paket firmware-iwlwifi dipasang. Menurut daftar isi paket, itu juga termasuk file firmware yang diperlukan. Metode ini khusus untuk Debian.
