You could use the BLE NUS peripheral and central examples to do such a transfer between your devices. The examples will relay anything they receive over UART to their connected peer over BLE, and the peer will output the messages received over BLE out on its UART, and visa versa. Test this according to the example documentation, and let me know if you encounter any issues or questions.
Did you send any data to the device? Did you see this data being output on the serial terminal of the connected device? The event will only be generated when data is received over the NUS service.
i am using serial bluetooth terminal to send the data.
Which application is this? Please be specific. Did you follow the instructions in the example's documentation when you tested the NUS example? Which step of the documentation did not succeed, and how did it behave different from what was expected?
The NRF UART smartphone application is indeed deprecated. You can use the nRF Connect application to connect to and communicate with your device running the BLE NUS application.
