fhempy: ble_monitor (Bluetooth Low Energy)

[Nighthawk]

Hallo Dominik,
scheinbar ist das integrierte BT Modul meines Rechners höchst instabil.
Ich habe jetzt ein USB Dongle bestellt, mit der Hoffnung dass es stabil wird.

[dominik]

Ja, die alten RPis sind nicht optimal. Ich hatte mir einen RPi4 zugelegt, da läuft BT relativ stabil.

Wenn du den Dongle hast, vergiss nicht hci_device umzustellen.

Hallo Dominik,

nach einem Update meines Ubuntus auf 22.04 bekomme ich gerade ble_monitor nicht mehr zum laufen.

Mein HCI hat sich zu HCI1 geändert und beim Versuch dies in MiScale zu ändern, bekomme ich folgende Fehlermeldeung:

und auch beim ble_monitor bekomme ich eine Fehlermeldung:

[dominik]

Hast du den lokalen BT Adapter deaktiviert? Nur hci1 ohne hci0 zu haben ist eigenartig 

[Nighthawk]

Das Abschalten im Bios ist leider wirkungslos, im OS ist aber die Interne Schnittstelle nicht zu sehen:

EDIT:

ich habe jetzt mal alle anderen EInträge ausser dem E8:48:B8:C8:20:00 im Ordner /var/lib/bluetooth/ gelöscht und nach einem Neustart wurde mein BT Device jetzt HCI0.
Leider bekomme ich weiterhin einen Fehler im ble_monitor, siehe unten.
Kann es daran liegen dass aioblescan nur daten liefert wenn es mit Rootrechten ausgeführt wird?
Wie bekomme ich den fhem user dazu auf die HCI Schnittestelle zugreifen zu können?

Poste bitte nochmals hciconfig -a, weil das sieht aus, als wäre es noch immer nicht da.

Mach bitte noch folgende Tests:

Code Auswählen Erweitern


sudo -u fhem bash
pip3 install btsocket==1.0.0

Danach nochmals ein Test. Wenn es nicht funktioniert, dann bitte...

Code Auswählen Erweitern


python3
import fhempy.lib.ble_monitor.bt_helpers
fhempy.lib.ble_monitor.bt_helpers.hci_get_mac([0,1,2,3])


[Nighthawk]

Bei dem ersten Befehlen bekomme ich die Fehlermeldung dass es die Version 1.0.0 nicht gibt:

Code Auswählen Erweitern

ERROR: Could not find a version that satisfies the requirement btsocket==1.0.0 (from versions: 0.1.0, 0.2.0)
ERROR: No matching distribution found for btsocket==1.0.0

[dominik]

Sorry, Tippfehler von mir. Sollte 0.1.0 heißen statt 1.0.0.

[Nighthawk]

Leider ebenfalls ohne Erfolg:
