CH376s interfacing issues

Hello ,
I am using UART interfacing .I try to read the file(TEST3.TXT)
UART_PutChar(0x57);
UART_PutChar(0xAB);
UART_PutChar(0x2f);
UART_PutChar(0x2f);
UART_PutString("TEST3.TXT");
UART_PutChar(0x00);

then

UART_PutChar(0x57);
UART_PutChar(0xAB);
UART_PutChar(0x32);

I have received 0xA1 only. it describes "Disk doesn’t format, or parameter is error, re-format by
WINDOWS with default parameter ". How to solve this issues

Welcome to the forum.

Could you explain it from the start.
Do you have a Arduino board ? Which one ?

That's a new and interesting chip. I have never come across it before, but it could be useful.

Did you search for an Arduino library for using this chip? It might be easier for you than sending codes in hex.

Please correct your post above, it is breaking forum rules. Code should always be posted using code tags.
