Connect a Laptop with Windows to Peripheral UART example

Sure, my question is very stupid, but after one day I found nothing to explain the principle of the situation, I decided to ask.

I have a laptop with built-in Bluetooth 5.2 and Windows 11. It runs a terminal testing program.

I have nRF5340 DK with the example Peripheral UART installed (nRF Connect SDK1.8.0). The board works normally, I tested it with a phone with Android and nRF Connect for Mobile. Everything is working fine. The board is connected to a desktop computer on which a terminal program is running and connected to COM port ( not USB).

Windows (laptop), sees the board. After pressing adding device (on Win), the LED on the board (connected) lights up for 1 second, Windows thinks about 5 seconds, and says try again. I imagine that it will connect to the board, and a window will appear to install a serial port to which I can connect through the terminal program. No PIN display window appears. I tried to quickly press button 1, possibly to confirm, nothing. I can transmit data over the phone without the board being BONDED. Let me just say that I've been doing Nordic for 6 months, and I've learned some things. But here I can't even imagine what should happen. Google didn't help either. Does anything else need to be installed on the board?

In the final version, it should be a remote device to which with any laptop with Bluetooth 5.2, to be able to connect and through a terminal program to exchange data via serial port.

Hi

I see, that would be the Bluetooth Classic profile Serial Port Profile (SPP). This is not supported in BLE unfortunately, so this won't be possible with nRF5x series devices, which only support BLE. You will need some sort of Dongle that is connected serially to the computer to get up a serial port on the PC.

Best regards,

Simon

Bad very bad. It was the idea of everything to connect the laptop to the device via Bluetooth. But I don't know in what language software should be written to connect to the device that was added to Windows. This device is currently unusable in Windows. The most important thing was not to plug anything into the ports of the laptop, because in a few months they die purely mechanically from turning on and off USB devices. I need to seriously rethink the whole strategy.

Thank you for your cooperation and time.
