Hi, I am using LinkOS SDK on Xamarin by following this tutorial:
Basic Xamarin Print Example
The printing is working, but the bluetooth connection is not closed after printing. As a result, another phone cannot connect to the printer until I manually turn off bluetooth on Android or iOS.
 
I did call the connection.close() method:
finally{     if (connection.IsConnected)          connection.Close();}
 
How should I close it?
