Can you please run AT+GMR and tell me what firmware version it is running?
Also, why do you get those busy p... etc messages? Which commands are not working well?

Snapshot of module information attached.

I am using AT+CIPCLOSE=<link id> command.It is successfully executed and received OK response. But after again connect module and try to communicate using module with another AT command then received "busy p..." response.

You have any documents which explain this messages condition?

Oops, you're using the oldest version of the AT firmware that exists!
You need to update your firmware, there have been hundreds of updates since this version. You may use AT+CIPUPDATE by connecting the ESP to an AP with internet access. Or just reprogram the firmware via UART (there are many articles online on this).

Thank you for reply.

I get latest bin file release of ESP8266_NONOS_SDK from git. But this is support to 8Mbit & 16Mbit flash as mention in release document.
I am using 4Mbit flash ESP8266. Can you please share 4Mbit flash module firmware update link.
