Just starting to look at BT with B4J for the first time.
Found the 2015 library
Ran the B4J test app.
It only finds one device, a cell phone.

Windows 10 system, about 1.5 years old.
The W10 settings for BT (Bluetooth & other devices, Add Bluetooth or other device) is able to find quite a few devices of various types (phone, TV, firesticks) including the device I'd like to connect to.

Does this library have some restrictions on device?

Do we need a library update?

Over the weekend I read quite a bit.
My target device is BLE.
I was able to successfully work with it in B4A (reading and writing and notifications).

Is SPP required to be able to map a com port to BLE device in W10, to be able to use jSerial?
This device has the ff00 service with ff01/ff02 vendor custom serial, so I think I'm out of luck for accessing it using B4J.

I found that (from the Microsoft store) the W10 Bluetooth LE app is able to see many BLE devices including my target, and list the services and characteristics, and I can write and read data. So if that App can, it should be possible to accomplish in B4J. I did not yet look for prior work to wrap.
