Martin,
My device shows the exact same.
Just got off the phone with tech support and they told me that they are having major issues with Android phones and the setup. If you are using ANDROID, find someone with an IPHONE or tablet and try the setup again.
If you are using an Andoid, I had to allow bluetooth to connect before I could even see the SER #. I was able to see the item when I scanned bluetooth devices and I went into the settings to allow.
Hope this helps some.
