CLAVIER bluetooth reconnu, connexion éphémère

Bonjour,

je cherche à utiliser un clavier bluetooth sur ma Jessie.

Avec la méthode Appairage avec bluetoothctl du wiki ([https://wiki.debian.org/fr/BluetoothUser#Introductio] j’obtiens les résultats suivants, optimistes jusqu’à la commande de connexion qui bégaie:

  5 $bluetoothctl

35 Failed to connect: org.bluez.Error.Failed
 36 [CHG] Device 03:A1:00:05:44:98 Connected: no
 37 [bluetooth]#

Ensuite j’ai mis à 1 le réglage suivant, dans /etc/default/bluetooth
HID2HCI_ENABLED=1

sans plus de succès.

(Il s’agit d’un clavier de la marque SilverCrest, acheté chez Aldi)

Merci

EDIT

Voici la suite des commandes et leurs résultats:
