Sennheiser BTD 700 dongle bluetooth

Support Debian
#21

Pour vérifier, que dit ceci:
systemctl restart btd700d.service

#22

Aucune sortie

#23

en root:
systemctl restart btd700d.service

et as-tu au moins rebooté une fois ?

#24 
sudo systemctl restart btd700d.service
Failed to restart btd700d.service: Unit btd700d.service not found.
#25

Oui, plusieurs mais je peux recommencer.

#26

Je viens de rebooter et j’ai toujours :

sudo systemctl restart btd700d.service
Failed to restart btd700d.service: Unit btd700d.service not found.
#27

btd700d.service dont le status est bien rapporté en user lance /usr/local/bin/btd700d, normalement accessible à root.
Il faudrait donc décortiquer ça plus en profondeur, mais pas simple sans boule de crystal.
Peut-être que tout va bien en dessous de la gestion Bluetooth, mais après ça devient compliqué via forum, sans pouvoir reproduire.

#28

Ok, merci de ton attention en tout cas.

#29

Et en root, ça dit quoi ?
btd700d

#30 
sudo btd700d
[sudo] Mot de passe de laguespa : 
btd700d: connected to dongle
btd700d: state -> Disconnected
#31

Je ne pense pas que root puisse lancer ce service dépendant de pipewire/wireplumber.
Le lancement correct serait en user (à confirmer):
systemctl --user restart btd700d.service

btd700d.service

[Unit]
Description=BTD700 PipeWire sink switcher
After=pipewire.service wireplumber.service

[Service]
Type=simple
ExecStart=/usr/local/bin/btd700d
Restart=on-failure
RestartSec=5

[Install]
WantedBy=default.target

Il faudrait voir les logs lors du branchement usb, puisque ‹ btd700d.service › est relancé toutes les 5s en cas d’échec.

#32

Bonjour Verner, dans quels logs je dois regarder ?

#33

dmesg , journalctl , peu importe. Juste chercher ce qui bouge

journalctl  -f
journalctl --user -f
#34

J’ai commencé par rebooter et lancé le commande sudo journalctl -f sans brancher le dongle. Je l’ai branché ensuite. C’est le second bloc de ce post.

Ce dongle est censé se connecter à quoi en Bluetooth ?
La déconnexion est peut-être causée par absence de demande d’appairage (hypothèse à la louche).

#36

Oui, c’est un dongle bluetooth et il y a deux récepteurs dans la pièce où je travaille. Je peux d’ailleurs m’y connecter avec la carte bluetooth de l’ordi. Avec le dongle par contre pas moyen…

#37

Un conflit de priorité entre carte Bluetooth PC et dongle externe ?
Configuration Bluetooth à clarifier en désactivant la carte BT interne ? BIOS ?

#38

Oui, j’y ai pensé mais je n’ai pas trouvé de moyen logiciel de désactiver le bluetooth du PC. J’ai un interrupteur physique sur l’ordi pour couper le wifi et le bluetooth mais ça donne la même chose :
