Windows Desktop App + Bluetooth Communication

[Edison J. B.]

Hi,

I need connect a Windows desktop app with bluetooth device to retrieve informations from a weight scale.

Is there any library for Windows bluetooth communication? I also would want to create a bluetooth scanner device to locate the weight scales that are registered and available to communicate in my app.

Thanks for any advice.

I just looked into this for BLE, it the same as BT

if your BT device supports RFCOMM, then there are built in solutions (access as a Com port) for most major OS. The $ library I  called out in the this thread supports several BT dongles and they have (new) support for FPC. otherwise it looks like you need to create an interface to a windows DLL (sorry I've forgotten it's name) that will be changing for windows 11 (rumors). 
good luck.

Thank's for your attention. I will study the library.
