Hi,

Same as in the title. Snprintf doesn’t print out float to the buffer instead it finishes the string with \0 just before the %0.2f value.

I am using linker flags: -specs=nosys.specs -z muldefs -u _printf_float -u _sprintf_float -u _snprintf_float
This is the snprintf: snprintf( cbuf, dataLength, “{ "t": "%0.2f", "h": "%0.2f" }”, t, h );

Regards
