I have a Windows app I have been working on that needs to connect to a bluetooth (BLE specifically) device, however, I have found a huge lack in information on how to do BLE at all for windows in Unreal Engine. There are a couple plugins for BLE, but they are iOS and Android specific, does anyone know anything about how to get BLE working for Windows in Unreal Engine?
Thanks!
I think UE does not support Bluetooth connection out of the box. I guess you’ll have to implement your own C++ code for this, using the Win32 APIs. This is an opportunity for a nice plugin 
(it seems there is a plugin for windows on the marketplace, just requiring for the device to be already paired: https://www.unrealengine.com/marketplace/en-US/product/port-windows)
Qt has ble modual, you can connect with it via IPC if you don’t want to link it together…
