Bonjour à tous. 
J’ai acquis une enceinte bluetooth JBL GO, l’idée est de lancer un script quelconque lors de sa connexion avec mon ordinateur.
J’ai lu divers sujet à ce propos par-ci, par-là mais aucun ne m’a réellement aidé.
Voici où j’en suis actuellement :
1 - J’ai récupéré les informations que j’ai pu avec udevadm lorsque la connexion s’effectue :
Résumé
user@fremen:~$ udevadm monitor -upk
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

2 - J’ai récupérer toutes informations à propos du dongle que je pouvais, lorsque l’enceinte est connectée
Résumé
user@fremen:~# udevadm info --attribute-walk /sys/class/bluetooth/hci0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

3 - J’ai tenté de créer une règle udev :
Résumé
ACTION=="add", SUBSYSTEM=="bluetooth", RUN+="/usr/bin/touch /tmp/bt_connected"
ACTION=="remove", SUBSYSTEM=="bluetooth", RUN+="/usr/bin/touch /tmp/bt_disconnected"
Au final… Rien ne fonctionne. 
Est-ce qu’un adepte des règles pourrait m’éclairer ?
Merci d’avance
