    Non funziona l'accoppiamento Cuffia AS9S con Smatphone (Samsung S9).
    Ho eseguito le seguenti operazioni:
    - Trasmettitore spento
    - Accensione mediante pulsante centrale (5 sec) -> "Welcome to Avantree" -> Accensione LED : solo BLUE (flashes). LED non cambia colore in RED (no "Pairing" message)
    - Attivazione Bluetooth su Smartphone.
    "Dispositivo Bluetooth rilevato : il nome del dispositivi verrà mostrato alla connessione di questo dispositivo"
    "Impossibile eseguire associazione con dispositivo. Controllate le impostazioni dispositivo e riprovate"
