@Einar Thorsrud yes but by which code can i send and receive

You can use for instance nRF Connect or nRF Toolbox apps for mobile.

how can i send message from mobile by connecting to one nrf52dk and receive by another nrf52dk and see the message in another mobile

No problem. Using the UART terminal is a simple way to you how it works. Did you test it? When you have it working you can modify the examples to send data from somewhere else as you like (such as a hard coded string upon button press or whatever you lie). It is up to you to adapt it as you want.

yes i need to send the message without the serial port and i cannot detect in nrf connect for moblie app where the both boards are connected

Have you done as explained under Testing in the documentation for the Nordic UART Service Client example (see the quote below, where I have highlighted step 6)?

Test the BLE NUS Client Example application by performing the following steps:

Compile the BLE NUS Client Example application and program both the SoftDevice and the application on the Central board.
On the Central board, observe that the BSP_INDICATE_SCANNING state is indicated. This shows that the application is scanning for a NUS service Peripheral.
Compile the NUS application and program both the SoftDevice and the application on the Peripheral board.
Observe that the NUS Peripheral is advertising.
Once the connection is established, the BSP_INDICATE_CONNECTED state is indicated on both boards.
Now it is possible to send data between the two boards. To do so, send data to one of the boards using the serial port. Observe that the data is displayed on the UART on the other board.
Disconnect the devices, for example by pressing the Reset Button on the Central board. Observe that the boards automatically reconnect and that it is again possible to send data between the two boards.

i loaded ble_app_uart example in board and ble_app_uart_c example in another they both connected but i am now stuck at "how to send the message and How to see the received message"

I see. Did you face any problems? If so, can you clarify exactly what you have done and exactly what is not working?

yes i read the example....i had done all the process but the beacon connected by the nrf connect or nrf uart app

I am happy to answer any specific question you might have, but it is better you read example documentation and example code to see how you use the example to send and receive a message (that is precisely what the example is intended to show, after all).

how to send the message and How to see the received message

RE: I need a code where one nrf52sdk sends a message and another nrf52sdk recieves the message

Please refer to the documentation for the UART/Serial Port Emulation over BLE example (peripheral) and the Nordic UART Service Client example (central).

can you explain briefly

RE: I need a code where one nrf52sdk sends a message and another nrf52sdk recieves the message

Then NUS examples (ble_app_uart) are what you need to check out. Keep in mind that you don't have to receive the message to send from UART, you can modify the example to get it from anywhere, for example hardcoding the string constants

messages like hello nordic

What kind of message do you want it to be?

For generic text messages you could try ble_app_uart example for the peripheral and ble_app_uart_c for the central device.
