The `iocp_bt` package implements Bluetooth client channels on Windows. * https://www.magicsplat.com/blog/exploring-bluetooth/%|%Exploring Bluetooth%|% Blog post / tutorial. * https://iocp.magicsplat.com/iocp_iocp_bt.html%|%Reference pages%|% * https://sourceforge.net/projects/magicsplat/files/iocp/%|%Download%|% [EB]: Ashok, thanks a lot for this new package with good documentation, which brings again more Windows functions in Tcl. I haven't tried the bluetooth part yet, but iocp rings my bell so I tried the @iocp::inet@ package. As noted in the documentation, ''The only enhancement offered by this command is significantly improved performance with reduced CPU load'', and just that is enough! I tried it in a custom socket messaging library, I confirm it worked identically in an application, but my connection is too limited to evaluate the performance. I also did a simple data exchange test on localhost, for which it is 2 times faster than using stock socket.
