No, you not understand me.
The little dongle is a ASUS bt 4.0 dongle, the device is a keysafe keeper (un llavero como decimos in spain) and uses a batery cell rs2032, then is BLE (and it not have discover mode!), however, i've others 2.0 dongles and may NOT detects this device.
The bluetoothdiscovery project enum the RADIO but not found DEVICES. In a few hours i've attach to this topic images in fact to understand me.
My main problem is that this ASUS dongle is short range (less 10 meters) and the parini sena ud100-g03 is 300 meters and for my app, need this range. Asus dongle uses MS Bluetooth stack of win10. Parini sena uses Bluesoleil stack. Attach to te dongle Parini, in the cd software, there are a liitle app that detects BLE devices and discover my little keykepper device, but your library, not.
Sorry my bad english.
