@kazi93, you need to try out the examples first. The send and receive functions are designed to send a 16bit number or an array of bytes. They are not written for “float” or other types. You will need to convert your 4 byte float into an array of bytes, send it and then on the receiver end, rebuild the float using the array of received bytes. Another way is to convert the values to text characters in an array (a string) and send the array. The receive end then takes that array of received characters and can print it out.
