In observeConnectDevice method you need to check if emitter is not disposed before send error or onNext. Please change this code emitter.onError(e) to next if (emitter.isDisposed.not()) emitter.onError(e)

@IvBaranov are you still support this library?

[IvBaranov]

Instead of using if (emitter.isDisposed.not()) you can use just emtter.tryOnError(e)
