Hi,

I have solved the problem.Who meets this problem can see my github(https://github.com/blguweb/nrf52840BLEToPC).

Is it possible to create this hardware configuration: serial communication between Host(PC) and nrf52 dongle, and wireless Bluetooth communication with nrf52 dongle and nrf52 dk to send and receive data without nrf connect apps?.

The HC-05 is a Bluetooth Classic device, which implements the Serial Port Profile (SPP). As far as I know, there are not any such profiles for BLE, which are supported natively by OSes. The Nordic UART service is a proprietary BLE service which enables transferring strings wirelessly, but support for this is not available in Windows, etc., and is not mappable to any virtual COM port in the OS.

For later OSes, you can use BLE API to connect and interact with BLE devices from applications. The alternative is to connect a second Nordic device to the PC to receive the NUS data over BLE and transmit it to the PC over UART. For instance, you can run the ble_app_uart_c example together with the ble_app_uart example, to create a two-way UART-over-BLE connection.

Hi thanks for the reference, but I want a a wireless connection between the host (PC) and the nrf board. Instead of using a serial communication (UART)

Hi, thanks for the reply.

My requirements are; I want to send the data from the nrf board to the PC by Bluetooth. My main concern is how to read the data from my PC without the need of nrf connect apps.

Maybe if it helps to explain my requirements: I used a similar device that uses bluetooth protocol, which is the HC05 bluetooth module, that is able to pair with the PC and send data to 'standard serial over bluetooth link comport' and read the data by using the pyserial library. But know I'm trying to do it with nrf52 DK, but for some reason I cannot pair it with the PC. I was using the ble_uart_app to connect the board with the PC.

Hi,

You can use the my example (https://github.com/jimmywong2003/nrf52_ble_transfer_jpg) for reference.

it is using the pyserial to connect the nRF52 board. And then at the phone side, you can use the ImageTransfer APK.

Hi,

Your requirements are not fully clear to me from your description. Do you get the data through the serial port and need this data into a Python application, or do you need to control the BLE device through the serial port? If you get the data through the serial port, you can use pyserial directly in your Python application.

If you need to control the BLE device from the Python application, you should look into our pc-ble-driver-py library.

Best regards,
Jørgen
