How to convert Float numbers to STRING then concatenate them?

[JohnnyK (Jan Kamidra)]

Hello,

try to change this

' , '

to this

", "

For float conversion you can try to check

• to_string - C++ Reference (cplusplus.com)
• Converting float value to a char [] - Mbed OS / Hello world! - Arm Mbed OS support forum
