Convert between binary and base64 encoded string. Easily convert sensor raw values, structures, etc...
This library made to convert binary data (e.g. raw sensor values) to base64 encoded string.
String can be convert by cast them to uint8_t*, but that not what this library is for, nor do we plan to provide means.
If you want to convert string, use this library and implement wrapper functions yourself.
See arduino_base64.hpp for details.
