Hi.
@mbedarff I fix gateway connection checking issue.
You can download the fixed version from my Google Disk
@mbedarff @ncollins I published all changes to GitHub, "mysensors-binding-addon" branch.
@forexsieno I tested my 3.3.0-SNAPSHOT in different environments (Arduino Nano as serial gateway, OH 3.3 installed on Windows 10 and Ubuntu Server 20.04) and did not find such a problem.
