Half Duplex Serial communication support for esp32

Postby Karim1993 » Wed Nov 14, 2018 9:20 am

Hi
Is it possible to use the existing uart driver as a half duplex serial trans-receiver. Below are the things I am trying to achieve.
1) Single gpio as TX/RX.
2)The first command will be transmission with a checksum in the end.
3)Upon transmission it will go receive mode and wait for data with checksum in the end.
4)baud rate is 19200
