B4J Question Bluetooth example b4j

[Zlgo]

Please correct me if I wrong use example for bluetooth b4j :
(https://www.b4x.com/android/forum/threads/jbluetooth-library.60184/#post-644669)

1. made pairing through WIN10 Settings with my LG K4
2. run example where in listview field show "LG K4(2017) B41DA858DF5"
3. choose this device and press "Connect"

After this step get return "Connected, success=false".
My first dilemma is do we need some application running in the same time on mob, and how implement jserial.lib in this situation. Bluetooth installed on my PC is not virtual COM ,at least I can't detect any additional serial ports.
Examine Bluetooth driver stay that is Microsoft 10.0.17763292.

Hi!
Thanks for your answer, but I went through these examples (serial port , sockets port) and they work fine for now. My interest is now on using bluetooth device which i got preinstalled on PC with Win 10 OS in communication with Android mob, so I have try this bluetooth example but no good results (description in my question).On my PC there is now virtual com port for bluetooth device . Is there limitation in bluetooth lib on various hardware, and how to know which is good to use with this lib?
It looks that my bluetooth adapter is not in scope of this lib if I'm using this example in good way!
Maybe I'm boring, but do I need some client app running on mob for this example to receive "Connected, success=true"?

Must correct myself "On my PC there is now virtual com port for bluetooth device" with "On my PC there is no virtual com port for bluetooth device"

Yes. You need to run the B4A app from that example on the mobile device.

Is it possible to get APK version of Android part of example to install on my mob?

You can download B4A trial and build the example. A newer version is available here: https://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768/
