Lubuntu 16.04で動作しないAtheros AR9285 Bluetoothデュアルモード
私の問題は、HP probook 4330にAR9285 bluetooth + wifiカードがあることです。インターネットからいくつかの方法を試しましたが、Bluetoothデュアルモードはまだ動作しません。
- Btcoex = 1を有効にする
主な症状：起動後、最初にbluetooth.serviceが停止状態になります。再起動後、Bluetoothマネージャーを起動できます。しかし、開くと、どのデバイスにも接続できず、Bluetoothアダプタがありません。
これが出力です。

hcitool devは、いかなる種類のアダプターもドロップしません。カスタムBTアダプターを接続すると、このためのデバイスハンドラーが戻ります。
私の意見では、正しいデバイス記述子がath9kドライバーにありません。
EDIT1：
Ath9k.confを削除しました
私は試した：
modprobe -rfv ath9k
modprobe ath9k btcoex_enable=1

アダプタが見つかりません、同じ結果。
Pilot6がath3kカーネルモジュールをロードしようとしたと言ったのでわかりました。今ではうまくいきます！ wifiとオーディオシンクの両方。
Sudo modprobe ath3k

永続的な解決策として、/etc/modulesを編集し、ath3kを追加する必要がありました。
