AT firmware and HW flow control
Posted: Tue Sep 04, 2018 5:56 am
I'm using WROOM32 module with AT firmware, and i need flow control from module to host MCU. I connected host RTS to ESP32 CTS (according to AT documentation it's GPIO15).
After i turn hardware flow control (AT+UART_CUR=115200,8,1,0,x - where x any flow control) I'm not getting any data for further AT requests, even though RTS is pulled low all the time.
Tried all three HW flow controls: ‣ 1: enable RTS; ‣ 2: enable CTS; ‣ 3: enable both RTS and CTS same happens.
What can be wrong.
