B4J Question any B4J BLE lib ?

[peacemaker]

Hi, All

I have found very useful functionality of Chrome web-browser: chrome://bluetooth-internals

that allows to work manually with BLE devices (under Windows 10, at my side).

But do we have no any wrapper or inline code for B4J BLE connections in 2023 ?

Last time that I checked I didn't find a good Java library for this.

Don't post links like this. You should read the details and understand them.
This library doesn't provide access to BLE. It helps with interpreting the data.

I guess you need to use something like this library, but it's in Python

I am also interested in the issue of using BLE in Windows
I didn’t find any programs for working with BLE, so I decided to write it myself, but unfortunately in B4J there are no libraries for working with BLE either...

this library

It's not Java lib

Yes, you are right.
I looked a lot for a library for working with BLE in Java, but I never found anything...

This is the trouble. I do not understand why it does not exist any Java Windows BLE lib...

We had done some tests like this:

[Web] BANano + BLE

Hi, I'm trying to learn BANano and I want to share a bit of what I've learned so far, any suggestion or comment is welcome. Sorry if I'm posting this in the wrong place, I'm just trying to learn. This is an example of connecting to Bluetooth (BLE) through the Bluetooth Web Api supported by some...

some tests like this

So, it is the same Web Bluetooth API stack like "chrome://bluetooth-internals", that is built-in into modern web-browsers...
But anyway it does not help to use Java apps without web-browser for BLE under Windows...

Correct..
I don't undertand why there is not a library..it depens of java/oracle if I'm correct.

There is some SDK from MS: https://learn.microsoft.com/en-us/w...bluetooth-driver-stack?source=recommendations
But it needs to hard work to implement it into a Java lib...

Someone in the forum told me that he/she give up about b4j library then started using a dongo and usb to b4j
