HI Vidar,

Sunil vignesh, so you are not receiving any data now? Do you receive data if you don't encode the data with sprintf?

I used as like collin said

by using sprintf i convert the float to string

but by sending data to mobile by using ble_nus_data_send();

it doesn't show in the mobile...

Just wanted to add a code snippet in case anyone came here looking for syntax

char buffer[100];
float f_val;
sprintf(buffer, "%.4f",f_val);

Hello,

You can use sprintf if you want to convert float values to a text string.
