Does HAL_UART_Transmit() sends ASCII or binary?

[M7890.1]

Hi! Does anyone know if HAL_UART_Transmit() sends ASCII or binary? I've tried to send some data a serial plotter but nothing is being plotted. The format of the data sent follows the setting in STM32CubeMx. (It works on Arduino serial plotter)

Serial plotter that I used: https://hackaday.io/project/5334-serialplot-realtime-plotting-software

arduino serial plotter has a sintaxis you should meet.

If i were you i would download realterm and check if youre sending the correct " " to separate data or /r/n when serial plotter expects them.
