I don't understand what you mean by that!
What have you tried?
Where are you stuck?

This is my code i am able to send the data from nrf52 dk to esp8266 through the serial monitor
In the above image I sent a string from nrf52 to esp8266 through the serial monitor .
I want to declare a static string and keep on sending it to esp8266.
Eg:
I am connecting a temperature sensor to nrf52 dk and I am sending the temperature data to esp8266 so that i can store it in cloud .
Still confused!
Your code shows that you do have a static string:
static char tx_message[] = "Hello nrf_serial!\n\r";
and your terminal screenshot seems to show that you can send it!
So I'm still unclear what the actual problem is!
BTW
Note that it is usual to have the Carriage Return (CR) first - ie, "\r\n" - giving CRLF
This is the process that i want to do .
I got the sensor data i want to send this data to ESP8266 how should i do that

So it's not static data, then - is it?
But you have the code right here:
ret = nrf_serial_write( &serial_uart, tx_message, strlen(tx_message), NULL, NRF_SERIAL_MAX_TIMEOUT) ; APP_ERROR_CHECK(ret);
The nrf_serial_write() function just sends data - it neither knows nor cares where that data comes from, nor whether it is "static" or not.
You just give it a pointer to (the start of) the data you want to send, and tell it the length of that data.
Simples!
static char tx_message[] = "Hello nrf_serial!\n\r"; static char k[] = "jio"; ret = nrf_serial_write(&serial_uart, k, strlen(k), NULL, NRF_SERIAL_MAX_TIMEOUT); APP_ERROR_CHECK(ret);
No this part is not working I tried
So what debugging have you done to find why it works with 'tx_message', but not with 'k' ?
Are you sure that your terminal doesn't depend on there being a CR and/or LF on the end?
It worked now actually i kept a delay and executed the code
