This is something it could work for me.
My question now is how do I know from host MCU when data are available?

Something like +IPDREADY or similar should be received from ESP to notify host MCU about new data.

Will this go in official AT software? Since I'm making new AT parser library this would be very great feature.

Well, the core AT firmware is only with the developers who work on it. I don't have it either. But I have forwarded this post to the team who may consider adding this in later versions of the firmware.

Let me know who I can contact for more informations regarding this features in core AT software provided from your side.

Hello pratik,

this is definetelly what I did for myelf, except I can't modify current AT software since it is precompiled.

But according to question I got regarding my AT parser library, this features would definetelly be usable by users.

Let me know who I can contact for more informations regarding this features in core AT software provided from your side.
Very useful features.

Hello, thanks for the suggestions! We will take this into consideration.
By the way, it is possible for anyone who writes programs for the ESP8266 to add custom AT commands. If you really need this done, you may contact ESP8266 developers on the forum to do it for you!
Officially rolling this out may take time. Thanks for using the ESP8266!

Request AT commands

2016-10-23T00:47:54+08:00

To make AT software really good (which this has potential), we would need also these commands, especially for low-RAM devices.

These are:
- Get data manually. Instead of auto +IPD, user should call AT+IPD command:
AT+IPD=n,x\r\n

where:
n..connection number
x..number of bytes to read

Response:
+IPD,conn_number,bytes_in_response,bytes_still_in_esp_memory\r\n
actual data here.

This feature could be activated or disabled using AT+CIPRXGET command.
This feature is also on GSM modules, where this is not primary feature. So I think it can be implemented easily here.

Another thing would be to limit +IPD data at a time.
If there is limit set to 100 bytes and there is 1460 bytes of network data, send 15 times +IPD statement.
Easier to work with when working with small RAM embedded systems.

Next command would be for set HOST name
AT+SETHOSTNAME="host_name"\r\n
