esp8266 sending speed
Posted: Wed May 24, 2017 11:20 amHello !
I use esp8266 as TCP socket server, and Unity as client (Written in C#).
And I use esp8266 send a string that contain 70 bytes to Unity client.
But it seems that it takes 3.3 sec to receive 100 times this string, I expected a higher speed.
So what sending speed do esp8266 have? Is there anyway to get higher?
Here is my Arduino code :
