The ESP-12 will manage all data in internal queues, so you cannot really overwhelm the UART unless you are REALLY forcing data on it.
Are you using the latest SDK?

Hello,
I dont use hardware flow control. I saw connections only with Tx Rx. Do you have some recommended hardware design manual for better communication between MCU and ESP12-E module?

You should not be getting this delayed data.
Are you using hardware flow control? Is that causing data to stay in buffer accidentally, maybe?

Receive Buffer Clear TimeOut

2017-07-07T21:16:22+08:00

Hi,

I commonly read a presumed response of an AT command (e.g. "AT+CIPMUX=1\r\nOK\r\n"). In some cases, there stay some old characters in the receive buffe, so I read e.g. "ERROR\r\nAT+CIPMUX=1\r\nOK\r\n"). Is it possible to flush the receive buffer before the next AT command send ? When I wait for a while (e.g 2 seconds), the recive buffer is then empty. What is the TimeOut of the receive buffer auto flush ? Is this time guaranted and same at all cases ?

Thank you,
Jan
