I want to send static data from nrf52 to esp8266. I have used serial Program from examples. I am able to send data dynamically from the serial monitor.

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 .
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
