Testing on Honor Band 3 NYX-B10
Hi @zyv I am testing your console with my honor band 3 to see if I can help with the integration with gadgetbridge. Unfortunately I am unable to do anything and I get this error:

Any hint?
Thanks
Operation failed with ATT error: 0x0e (Unlikely Error)
Hello everyone again! I was finally able to hook up to the watch, but code gives an authentication error, I looked at the logs in wireshark and found such a line
after the watch send an authentication error
in the watch logs I found a string with authentication, but does not coincide with the authentication request in the script, what should I do?
How to setup default values?
Hello, I'm trying to run your app with my Huawei band 3 pro.
As I understand, I shoud write smthing like this:
DEVICE_NAME = "HUAWEI Band 3 Pro-B0D"
But what should be in
"device_uuid" field?
Also should I download band.ini anywhere?
Huawei Band 7
Hi zyv! I have a question, can I use your script to connect to a Huawei Band 7 watch? And if so, how? What is device_uuid in band.ini file?
Trying on a Honor 4 Band
Ok so I'm a total newbie with BLE devices. Here is what I got after a few attempts. It looks like I had to turn bluetooth off on my phone and have the band in an "unpaired" state.

My idea is that you can directly get the data like the number of steps today and the cell phone battery through Bluetooth
