Amazfit NEO pairing #375

Open jmlich opened 1 month ago

jmlich commented 1 month ago

There are many differences from my previous try:

I am trying to pair with Amazfit NEO. The device is connected to zepp application and I am getting token with

$ python3 -m huami_token -m amazfit -e user@domain.com -p 'Password' -b
...CUT...
╓───Device 0
║  MAC: E1:87:29:30:E4:E7, active: Yes
║  Key: 0xcaa04207ff084f260d8513a5d75d8dcf
╙────────────

The 0xcaa04207ff084f260d8513a5d75d8dcf (including 0x) was entered into dialog.

I can see authfailed message in daemon's log:

2024-05-12 17:34:36.615 : void MiBand2Service::characteristicChanged(const QString&, const QByteArray&) Changed: "00000009-0000-3512-2118-0009af100700" "\x10\x83\b"

It looks like the "\x10\x83\b" is the unexpected data. Maybe also @kirbylife can take a look.

The Gadgetbridge is able to connect to Amazfit NEO without troubles. I tried to compare the pairing mechanism in gadgetbridge and amazfish. So far I can see the only difference, gadget bridge is using bytes 3-19 and amazfish bytes 3-17:

https://codeberg.org/Freeyourgadget/Gadgetbridge/src/branch/master/app/src/main/java/nodomain/freeyourgadget/gadgetbridge/service/devices/huami/operations/init/InitOperation.java#L163

https://github.com/piggz/harbour-amazfish/blob/8efe63483330b31ff00728ad8e8c0f1b609bb547/daemon/src/services/miband2service.cpp#L44

The value "\x10\x83\b" for characteristics corresponds to this condition

value[0] == RESPONSE && 
(value[1] & 0x0f) == AUTH_SEND_ENCRYPTED_AUTH_NUMBER && 
value[2] == 0x08

doesn't seems to be handled in gadgetbridge either.

Are you able to pair other Amazfit watches on that version of Amazfish? or only the NEO is the one with the problem? Because it seems that the erroneously fetched data issue may also correspond to a problem of using the miband2 service for the Neo.

jmlich commented 1 month ago

I don't have any other Amazfit device to test.
