Re: 20.04.1 LTS: Πρόβλημα με bluetooth σε Lenovo laptop

Δημοσίευσηαπό Reinach » 28 Ιαν 2021, 13:39

Από τις πιο πάνω εικόνες που έβγαλα από τον Device Manager των Windows, βλέπω ότι στο Hardware Ids της συσκευής bluetooth δίνει:
Κώδικας: Επιλογή όλων
BTH\MS_RFCOMM
που μάλλον λέει πως η συσκευή είναι της Microsoft και ονομάζεται RFCOMM (;). Ψάχνοντας, εύκολα βρίσκει κανείς πως υπάρχουν drivers για τη συγκεκριμένη για τις διάφορες εκδόσεις των Windows. Π.χ.
https://www.driverscape.com/download/bluetooth-rfcomm

Είναι σωστά τα παραπάνω; Για Ubuntu τι κάνουμε; Υπάρχει σε κάποιο firmware update κάτι άραγε;
Επίσης σε μια από τις επόμενες εικόνες που ανέβασα και που αφορά το Intel Wireless Bluetooth δίνει τα εξής:
Κώδικας: Επιλογή όλων
USB\VID_8087&PID_0AAA&REV_0002
από όπου υποθέτω ότι Vendor: 8087 και Συσκευή: 0ΑΑΑ. Είναι τα στοιχεία της σωστής συσκευής bluetooth αυτά όμως; Από την αναζήτηση στο PCILookup όμως με βάση τον Vendor προκύπτει:

όπου όμως δεν υπάρχει το συγκεκριμένο Device ID (αν το έχω ψάξει σωστά).
Έχετε κάποια ιδέα τι μπορώ να κάνω με αυτά;

Edit: Είδα τώρα εδώ:
http://manpages.ubuntu.com/manpages/trusty/man1/rfcomm.1.html
ότι υπάρχει το πρόγραμμα rfcomm για τη διαχείριση των ομώνυμων συσκευών σε linux. Αυτό ανήκει στο πακέτο bluez που δεν είναι όμως εγκατεστημένο στο σύστημά μου.
