HAL Library UART Problem

Hello everyone;

I'm using a STM32F4-DISCOVERY BOARD, when i'm trying to send datas over hal uart it only sends ASCII types of datas but in my project i must send binaries, strings, floats, chars kind a all of the data types. But as i mentioned it only sends ASCIIs. I need help :(

Thanks for your attention.

 HAL_UART_Transmit(&huart2, (uint8_t *)charArray, strlen(charArray), 10);

  **** This is the code which i'm using
