Hi kai-morich

before anything i want to say thnaks to your very great job in this app
I'm preparing an app to connect to a low voltag blutooth like your app . i've done every thing you do in your app in github but i still get this error when i try to connect to the device .
with your app i connect to the device with no problem .
do you have any idea what cause of this error ?

thank you in advance
