My sketch is a bit ore complex and larger , and i had the " no more response" problem.

I did not resolve that but i think that this is cause by the Hardware serial buffer size of arduino that is smaller than the esp8266 buffer size. So, if it's got a lot of information , arduino could not read them as quickly as we are hoping ----> overflow.


You can go to "<arduino-home-directory>\hardware\arduino\cores\arduino" and find line:
#define SERIAL_BUFFER_SIZE 64

and change it to whatever you require (given that the controller can take it :) )

Hope this helps

Could you please give some statistics for latency? My ESP response is quite slow (2 seconds min, 11 seconds or fail max)

you gotta free the used channel via AT+CIPCLOSE command before refreshing. I haven't tested it, but it sounds reasonable to me. Hope this could help.
