What makes you think that this wrapper library is performing a disconnect? seems more likely the implementation is not keeping the connection open. Do you have any logging in place on the device to see if the device is being disconnected?

Ok, i think i know your issue, https://github.com/Reedyuk/blue-falcon/blob/1f6960d4bab9e98f792354a11cbcf431c7f7429a/library/src/commonMain/kotlin/dev/bluefalcon/BlueFalcon.kt#L19

You need to make sure that you pass TRUE for autoConnect.

blueFalcon.connect(device, true)

I believe you are probably using the default value which is false.
