Backwards Compatibility with Mi Band 1A and 1S

[rhyswilliamsza]

Hey!

Really love the work. I'd like to help out by introducing backwards compatibility for the Mi Band 1A and 1S. Any tips as to how I should go about doing this, as I've grappled with the code but couldn't get the authentication working correctly. Any tips? I have the necessary UUIDs, however I can't get the GATT service to activate.

Thanks!

Rhys

@rhyswilliamsza thanks for your interest!
Did you check out this project? https://github.com/freezed-or-frozen/MiBand1A
Does it work for you?
In general, it looks like the protocol is a whole lot different from MiBand 2.

Regarding your question. WebBluetooth requires proper initialization of filters and optionalServices:

.. which I believe are different in your case

I did have a look yeah! Works for 1A, however I have the 1S pulse so the protocol is quite different from even that. I've tried messing around with it, but haven't got very far.

It seems that the 1A and 1S use more standardised BLE protocols.

Let me have a look at that. Not sure how I would implement it, but keen to check it out and have a look. Mind if I send you a message should I get stuck?

Sure. Can't test on my side as i don't have any other MiBands ;)
