I am using SMING framework. What is the maximum size that the ESP8266 UART can receive at any one time? If I were to transmit a string of X bytes to ESP UART, what is the maximum size of X?

I was able to change the Rx by: editing HardwareSerial.h
I changed from 256 to 1024, I think Tx buffer is also 256

change -- HardwareSerial.h RX BUFFER SIZE 1024

Is this the same size for the TCP Buffer ?

Anyone know where to increase this size ?

Thanks
