No, but at least user space application (= it isn't built into operating systems like Android or Windows).

Also there is another misunderstanding: while you cannot have virtual serial port over BLE out of the box with systems like Android or Windows you don't need "driver" since these systems (starting from some version like Android 4.3 and Windows 8 etc.) support generic BLE GAP&GATT APIs. So what you can have is standard Windows or Android or iOS application which uses built-in HW and BLE SW stack. And as explained there are even examples of these by Nordic and other developers.

Note that this has nothing specifically to do with the BLE Nano.

As stated, there simply isn't any such profile defined by the BT SIG - so you would have exactly the same problem whatever hardware you chose from any manufacturer.

However, plenty of people have managed to do this kind of thing perfectly well with the Nordic BLE UART Service

So if I want to use BLE_Serial (nordic uart service) example as a base, I would need a driver on a PC side?

So if I want to have a simple stream-like communication channel, there is no standard solution? I need to implement something like BLE_Serial example and to have a custom driver on an other end? ***. Seems that I made a wrong turn choosing BLE Nano...

(still NUS examples in nRF5 SDK are only for embedded part, he needs also something to emulate the counter part on rich OS device...)

Do you mean pc <--uart--> BLE nano? The sample code from the ..\nRF5_SDK_12.2.0_f012efa\examples\peripheral\uart folder should be a good starting point for your experiment.

Or do you mean pc with BLE support <--BLE--> BLE nano? Then you mean want to look at the sample code in the ..\nRF5_SDK_12.2.0_f012efa\examples\ble_peripheral\ble_app_uart folder.

Not really because there is no Bluetooth Low Energy profile or service definition by BT SIG (or similar standardization body) for virtual COM port (or other form of "serial" communication). If you want to object that your PC can do that over Bluetooth with any phone or similar device then it's Bluetooth classic (BR/EDR) not Low Energy. There is popular Nordic BLE UART Service implementation in nRF5 SDK which simulates basic serial full-duplex link over BLE (no flow control, you need to take care about these things on higher layer) but for that you need specific app on both sides. Still there are all iOS/Android/Win/Linux/Mac implementation available by Nordic in some form so it might be what you want...
