Does transmit work if you send characters or strings?

C​onnected how? CMOS levels not compatible with RS232

actually I tried this using USB to TTL converter with nucleo-f446RE

what I need to use ?

like USB to RS232 converter After make a 232 to Micro controller.

or USB to RS485 converter after 485 to Micro controller.

this kind of stuff for receiving & transmitting Hex data.
