i.MX 8M Mini - RS232 Not working with CTS/RTS

Hi,

We are using MAX3232EIPWR transceiver for RS232 Communication, RS232 Send receive working without CTS/RTS, Only receive is working with CTS/RTS. May i know the why ?

Hi Manu

there may be confusion related to DCE/DTE mode and RTS/CTS signal direction,

one can recheck them using Figure 16-10. UART external signals to module signals routing with respect to DCE/DTE mode i.MX 8M Mini Applications Processor Reference Manual

Best regards

Thanks for the reply igor,

We are using DCE Mode only and as per DCE mode only we are making external HW connection but still we are facing issue with transmit with CTS/RTS.

Best Regards,

Manu
