Le Bluetooth ne fonctionne pas en 20.04

Saturnin51

Bonjour,

J'ai 2 matériels d'astronomie qui fonctionnent en Bluetooth, avec un module Bluetooth Arduino HC-05.
Je n'avais aucun problème d'utilisation en version 18.04.
En 20.04, l'appairage s'effectue mais pas la connexion.
Tout ce que j'ai trouvé sur le net comme solution concerne du matériel audio et n'est donc d'aucun secours.
J'ai tenté la connexion par un bind, qui a fonctionné un temps, mais ayant essayé ce week-end, cela n'a pas fonctionné. Je suppose que l'on exécute le bind après l'appairage.

Une idée SVP ?

Bonjour,

C'est une suite d'[ABANDONNE] Un problème de connexion par Bluetooth ?

Il faudrait fournir, en te servant du Retour utilisable de commande :

uname -a; lspci -nnk | grep -iA3 net; lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; lsmod | grep bluetooth

dpkg -l | grep blue

rfkill list all

et avec un terminal dont au préalable la fenêtre est élargie, afin de ne pas tronquer les lignes :

sudo service bluetooth status

Realtek ne fournit pas la configuration pour "rtl8821a_config", vous pouvez faire un lien symbolique avec rtl8723d_config.

Il faudrait d'autres intervenants.

Saturnin51

En fait aucun matériel Bluetooth ne fonctionne en 20.04 ! Personne d'autre n'a ce problème ?

Saturnin51

Après avoir relu les différents posts, il s'avère qu'il faut simplement désactiver le Secure Boot du Bios du PC pour que le Bluetooth soit fonctionnel !!!!!
