Herzfrequenz Messung mit Xiaomi MiBand 1S und BLE

Ich versuche, Herzfrequenzmessung Benachrichtigungen auf meinem Computer von Xiaomi MiBand 1S mit Python und pygattlib.Herzfrequenz Messung mit Xiaomi MiBand 1S und BLE

Ich kann das Gerät erfolgreich mit Benutzerinformationen initialisieren (Tippen auf den Sensor auf "paaren"), die gleichen Benutzerinformationen für die folgenden Verbindungen verwenden, das Gerät vibrieren, Geräteinformationen und Schrittzähler lesen und auf Schrittzähler-Benachrichtigungen warten.

Sobald ich jedoch den Herzfrequenzsensor-Kontrollpunkt in den manuellen Modus umschalte (Schreiben 0x150201 auf Wert 0x4e/Uuid 0x2a39), beginnt der optische Sensor auf der Rückseite des Geräts zu blinken, aber ich erhalte keine Antwort und meine Bluetooth-Verbindung wird unterbrochen, sodass ich keine Herzfrequenz-Benachrichtigungen erhalten kann!

Hier ist das Protokoll hcldump für die Sitzung mit Verbindungsdetails und Aufzählung von Diensten und Merkmalen. Skip nach unten, um das Problem zu sehen.

Dies ist, wo der Spaß beginnt! Zuerst authentifiziere ich mich mit dem Gerät, indem ich Geräte-Informationen lese und die gleichen Benutzerinformationen schreibe wie bei der Initialisierung des Geräts, für das ich 0x05 ("authentication ok") auf dem Benachrichtigungs-Handle 0x1b/uuid 0xff03 erhalte.

Dann aktiviere ich Herzfrequenz Benachrichtigungen auf Handle 0x4c/Uuid 0x2a37.

< ACL data: handle 64 flags 0x00 dlen 27 
    ATT: Write req (0x12) 
     handle 0x0019 value 0xf6 0xe4 0x63 0x5c 0x01 0x1e 0xc1 0x4a 0x00 0x04 0x00 0x31 0x35 0x35 0x30 0x30 0x35 0x30 0x35 0x00 
> HCI Event: Number of Completed Packets (0x13) plen 5 
    handle 64 packets 2 
> ACL data: handle 64 flags 0x02 dlen 5 
    ATT: Write resp (0x13) 
< ACL data: handle 64 flags 0x00 dlen 9 
    ATT: Write req (0x12) 
     handle 0x004c value 0x01 0x00 
> ACL data: handle 64 flags 0x02 dlen 8 
    ATT: Handle notify (0x1b) 
     handle 0x0016 
     value 0x05 
> ACL data: handle 64 flags 0x02 dlen 5 
    ATT: Write resp (0x13)

Schließlich schreibe ich auf Herzfrequenzsensor Kontrollpunkt. Ich erhalte keine Schreibantwort für diese Schreibanforderung (0x13) und Verbindung unterbrochen wird:

< ACL data: handle 64 flags 0x00 dlen 10 
    ATT: Write req (0x12) 
     handle 0x004e value 0x15 0x02 0x01 
> HCI Event: Number of Completed Packets (0x13) plen 5 
    handle 64 packets 2 
> HCI Event: Disconn Complete (0x05) plen 4 
    status 0x00 handle 64 reason 0x08 
    Reason: Connection Timeout

Wie Sie sehen können, statt 0x13 Schreibantwort empfangen, erhalte ich HCI Ereignis Disconn Complete (0x05) mit Vernunft Code 0x08.

Was mache ich hier falsch?

Schreiben 0x150200 an den Griff funktioniert gut. Schreiben von 0x150001 (Aktivieren der Schlafanzeige), 0x150101 (Forts. Auslesen aktivieren) oder 0x150201 (Manuelles Auslesen starten) bewirkt sofortiges Trennen. Das Gerät blinkt weiter, wenn die Sensoren im Schlaf- oder Fortsatz blinken. Auslesen ist eingestellt, also sieht es so aus, als ob mein Befehl das Gerät erreicht, aber ich kann nicht finden, warum die Verbindung fallen gelassen wird.

Ich verwende Ubuntu, Linux-Kernel-Version ist 4.4.0-22-generic mit bluez Version 5.37-0ubuntu5. Befehl btmgmt Info zurück:

$ sudo btmgmt info 
Index list with 1 item

Wenn Sie nach dem Schreiben eines Befehlspakets immer Connection Timeout (0x08) erhalten, ist es im Bluetooth-Stack Ihres Computers nicht falsch. Es scheint eher, dass Ihr Herzfrequenz-Messgerät ausflippt, wenn es diesen Befehl empfängt. Möchten Sie 0x150201 in Little Endian schreiben? Dann sollten Sie 0x01 0x02 0x15 statt 0x15 0x02 0x01 schreiben. – Emil

Nach [diesem Quellcode] (https://github.com/Freeyourgadget/Gadgetbridge/blob/98999993e58260afb770f5373f74649c673a44c2/app/src/main/java/nodomain/freeyourgadget/gadgetbridge/service/devices/miband/MiBandSupport.java#L236) und das Bluetooth-Protokoll, das ich von meinem Handy bekommen kann, während ich die offizielle xiaomi miband App benutze, ist die Sequenz 0x15 0x02 0x01. –

Es ist sehr wahrscheinlich, dass ich vermisse, einen Befehl vor diesem zu senden, oder dass ich den Sensor nicht richtig initialisieren kann. Aber verglichen mit anderen Quellen online und dem aufgezeichneten Protokoll sieht es so aus, als würde ich alles tun, was benötigt wird. Es wäre großartig, wenn jemand Erfahrung mit diesem Gerät hat oder einen anderen Grund teilen könnte, warum ich ein Unterbrechungsereignis erhalte ... –

ich es geschafft, eine Messung zu machen, die von der offiziellen Anwendung schnupperte Pakete fertig zu werden, aber wenn ich später die gleiche etwas zu tun versucht, es funktionierte nicht mehr, und jetzt habe ich dein gleiches Problem. Haben Sie das Problem über die Trennung nach dem Schreibbefehl in Handle 0x004c gelöst?

Hier sind die Shell-Befehle, die eine Zeit gearbeitet:

und die Herzfrequenz 0x47, die letzte Nummer.
