Android Question Connecting to Mi Band 2 with BLE2 Library

[he4a]

Hi folks!

I've been trying to write a simple app for mi band 2, but unfortunately I haven't been able to connect it!

I have been using a slightly modified version of the Demo posted in the BLE2 Library Thread:
https://www.b4x.com/android/forum/threads/ble-2-bluetooth-low-energy.59937/



The difficult part with Mi Band 2 is the fact that the connection process is a bit different than it was with mi band 1! You have read and write a few characteristics during the auth process.

Full description is here:

I just can't change the connection process. All I can do with this Library is use the BleManager2 Object with its .Connect function, which doesn't work. Is there another library? Any ideas??

Greetings Rob


This is what it looks like: Always Discovering Services, then Disconnected....

You cannot do anything until you connect. Based on the logs you were not able to connect, right?

Yes! This is what the successful connection process with the Mi Band 1 looks like.

Missing the "Connected" msg when trying with Mi Band 2... it starts with "Discovering services." and immediately goes to "Disconnected"

Funny enough I have been able to connect to the Mi Band 2 and discover its services and characteristics when using the app "nrf connect" from nordic semiconductor

What are these logs? I see that you are connected here.
