Bluetooth - carte non trouvée - MT7630e

Rodcotcot · Le 22/05/2020, à 14:39

Bonjour a tous,

Bonne nouvelle j'espère : sans rien faire, j'ai perdu l'usage du dongle 4G pour ma connexion internet (résolu, il m'a suffit de relancer le PC). Au même moment, pour la première fois sous Ubuntu, le sigle bluetooth est apparu (il y est encore après avoir redémarré le PC). Je ne sais pas ce qui c'est passé et c'est pas une mise a jour depuis la dernière fois.

Pour le retour de la commande de @Nuliel ( lsusb | grep -i mediatek ) j'obtiens ce retour :

cotcot@cotcot-N751JK:~$  lsusb | grep -i mediatek
Bus 003 Device 004: ID 0e8d:763f MediaTek Inc.

Je ne sais ni comment ni pourquoi, mais ca avance... ... après des années de recherche.....

Rodcotcot · Le 22/05/2020, à 14:44

Par contre, dans les paramètres bluetooth, il me demande toujours d'activer le bluetooth. Pour le moment, la carte est sortie du bois, maintenant, il faudrait la mettre au boulot...

Bonjour,

Je lis dans > askubuntu.com/questions/832702/how-can-i-setup-bluetooth-on-16-04-lts

Depuis que j'ai ce PC, sous Ubuntu, il n'a jamais voulu du bluetooth (voir post précédent). Aujourd'hui, c'est la première fois qu'il se rend compte que la carte est bien présente. Ca marche très bien sous windows... Mon Acer (mon autre PC) n'a aucun problème, a chaque installation ou mise a jour ou a niveau, tout est détecté du premier coup. Mon Asus (celui-là), c'est une autre paire de manche.

Bizarre, je ne trouve pas cette sitation. De plus, il semble que ceux qui ont posté on vu leur problème résolu, donc doit fonctionner.... Enfin, je pense....

C'est pourtant dans les commentaires :

Please edit your question and add output of lspci -knn | grep Net -A2; lsusb terminal command. – Pilot6 Oct 3 '16 at 19:34

Hello, I'm using Ubuntu 16.04, and the wi-fi now works (I've installed it with dkms), even if every now and then it stops working and I have to deactivate and activate the wi-fi again to be able to connect again, but bluetooth still doesn't at all. I don't even see the symbol on the top bar. I unblocked it (it was soft blocked) and tried using bpatch, but that's what I get:

Thank you very much, Bluetooth works now! The Wi-Fi connection still gives me the same problems, though. It happens quite often.

Hello, when I install driver it works good for some time (it depends sometimes its 30min sometimes few hours) and after that connection drops and I need to restart network manager to get it working again. also monitoring seems not to work correctly. Is there anything I can do to fix this? maybye its because of bluetooth error, because on my laptop I dont have bluetooth at all.

Sorry for late reply, If the bluetooth is hard blocked, then there's nothing I can do to help. But the connection drop problem may need more investigation. You can follow these bug reports for more info:

ubuntu 13.10 14.04 14.10 gets "hardware disabled" error, with hard blocked=yes even if my laptop dont have switch and fn+f2 dont help. 15.04 up to 16.04.* with kernel 3.16 up to 4.* gets error mentioned above. Also I try to not install btloader and mtxx.bin files and soft block bluetooth but thats dont help. Also when my connection drops, and i reboot to windows i get bricked wifi card and to restore it i have to poweroff laptop and wait for ~5sec. that helps until next drop when using ubuntu.

P.S if I install driver on ubuntu 15,04 or later when I type iwconfig I see "wlp30f0"instead of "wlan0". My laptop model is Asus X552C

Its ubuntu and ubuntu GNOME 13.10 up to 14.10 gets „hardware disabled“ bug. Rfkill shows hard block and my wifi dont even have switch. Fn + f2 dont help. 15.04 up to 16.04.*, so 3.16 up to 4.* kernel gets error mentioned above. Also i've tried not to install btloader and mtxx.bin but that didnt help. Also when wifi gets bricked and i reboot to windows my wifi card remains bricked so i have to power off laptop and wait for ~5sec to fix that problem. But that only helps until next brick.

P.S I've tried not to install bitloader and mtxx.bin files + soft block bluetooth but didin't get any results for wifi

P.S.S After connection gets dropped and bricked when I dual boot to windows, my wifi card gets bricked also. Turning off laptop of power and waiting for ~5sec fix problam until next brick.

Ok. Au temps pour moi. Par contre, si tu poursuis la lecture, il y a ecris que le BT est bien supporté.....

Oui, c'est justement ce qu'on fait, le module custom

Une fois que c'est fait, tu passes:

make prepare
make modules_prepare
make M=scripts/mod
make M=drivers/bluetooth/ modules
sudo cp drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth

puis un redémarrage et

[hs] Salut Nuliel,
Je n'ai pas l'habitude de network-manager pour créer un hotspot WiFi, j'utilise hostpad... Si tu peux jeter un coup d'oeil ici : ./viewtopic.php?id=2052970 Par avance Merci

oups....

Device is not available: No such device

Je remet le " build/linux-4.15.0/drivers/bluetooth/btusb.c " ? j'en ai fait une copie de sauvegarde.... Fallait bien tout remplacer dans le fichier ? Parce que j'ai fait un copier-coller de tout a la place de ce qu'il y avait....

Rodcotcot · Le 22/05/2020, à 20:02

Dans le répertoire, je me retrouve avec plein de fichiers que je n'avait pas avant, des ".mod.c" et de ".ko" que je n'avait pas avant....

Nuliel · Le 22/05/2020, à 20:05

Oui il fallait tout remplacer dans le fichier. Par contre j'aurais bien aimé voir le retour des commandes passées.
Je repasse un peu plus tard

Rodcotcot · Le 22/05/2020, à 20:24

Bon, j'ai remis le fichier comme a l'origine grace a la sauvegarde et j'ai repassé les commandes. J'obtiens ca :

" hcitool scan " donne ca :

cotcot@cotcot-N751JK:~$ hcitool scan
Device is not available: No such device

Et je crois que le wifi c'est barré.....

ps : c'est avec le fichier d'origine. Je re-tente avec celui que tu as donné....

Après avoir redémarré, j'obtient :

cotcot@cotcot-N751JK:~$ hcitool scan
Device is not available: No such device

Et pour le wifi, sur dans les paramètres, il m'indique " micrologiciel absent " dans le bandeau gris, juste sous " Wi-Fi " tout en haut. Je vois pas trop le lien entre les deux, le bluetooth et le wifi bien qu'ils soient sur la même carte.....

ps : c'est quoi le pendant de " format c: " pour ubuntu ?

Nuliel · Le 22/05/2020, à 20:50

Tu as passé les commandes après avoir repris le contenu du fichier que je t'ai donné ou avec ce qui était à la base?
Tu peux donner

dmesg | grep bt

Ok Nico, je passe voir ce fil

J'obtiens ca :

cotcot@cotcot-N751JK:~$ dmesg | grep bt
[    9.053457] mtk_bt_loader_probe: ret = 0
[    9.053487] usbcore: registered new interface driver mtk_bt_loader

J'ai remis le fichier d'origine, j'ai passé les commandes, j'ai relancé. Comme ça n'a rien donné, j'ai refait une seconde fois avec le fichier que tu m'as donné : copier-coller - les commandes - copier-coller du résultat - relance de l'ordi - passage de " hcitool scan " et copie du résultat.
