Bluetooth dongle for passive monitoring

I am looking for a Bluetooth dongle that's supported by FreeBSD.
Its intended use is primarily to passively receive Bluetooth (BLE) broadcast advertisements transmitted by sensors.
So, the candidate dongle should have good reception sensitivity. I think that an external antenna should be a big plus.
I am not sure if all Bluetooth devices support BLE, if not then BLE support is a must.
I guess that Bluetooth 5 support would be a plus as well.
