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

[Naralasetty Praneeth]

i have 2 nrf52dks where one nrf52sdk sends a message and another nrf52sdk recieves the message....for that what should i do 

Thank you in advance

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.

[Naralasetty Praneeth]

messages like hello nordic

[CodeLoader]

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

[Naralasetty Praneeth]

can you explain briefly

[Einar Thorsrud]

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

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

[Einar Thorsrud]

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).

[Naralasetty Praneeth]

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

[Einar Thorsrud]

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

[Naralasetty Praneeth]

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"

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:

1. Compile the BLE NUS Client Example application and program both the SoftDevice and the application on the Central board.
2. 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.
3. Compile the NUS application and program both the SoftDevice and the application on the Peripheral board.
4. Observe that the NUS Peripheral is advertising.
5. Once the connection is established, the BSP_INDICATE_CONNECTED state is indicated on both boards.
6. 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.
7. 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.
