esp8266 wifi protocol

[mril]

hi guys,
I saw in Espressif esp8266 datasheet that, the esp8266 has 3 Wi-Fi protocols 802.11 b/g/n, I've made a program with an FPGA to control communication between 4 esp8266's using last command At release, my question is, how to know which Wi-Fi protocol I've used , because I've seen that each one has different characteristics .
Greetings.

Hello,

If you want to work on power levels, protocols or reliable data rate controls, we suggest you to use the ESP8266 SDK for programming the ESP8266 directly. You can also program custom AT commands that do exactly what you want them to.
The AT commands right now do not provide protocol level control as it is not really required by most applications using AT firmware.
Thank you for your interest in ESP8266!
