hi, i have a project to control RC car from website ex: thingspeak or etc use arduino + esp8266, but i get some problem where esp8266 get delay 1-5 second to respond data from web instead i need very fast respond data from web to control RC car. i try to make delay in arduino sketch become milisecond is succed for 2-5 time but after that my esp8266 respond busy inet and problem like that.FYI i use AT+Command in arduino to send and respond data. what should i do ? what kind best method to send data ? thanks for your help

Why are you using the internet?

Let the ESP open an access point and connect directly to it.
You will forget about the word responsetime when you do that.

You could use UDP instead of TCP/HTTP since being a simpler protocol it is much faster with low latency.

You can use this Simple Serial to UDP bridge as the basis for your project. https://github.com/dyum/esp8266-serial
