[QUESTION] How do I get more information on the ESP-12E Command set?

[androiddrew]

Intermediate-ish Micropython user here. I see there are AT commands in the examples for setting and interacting over uart with the ESP-12E that comes with the board. How do I get more information on the firmware that the ESP-12E is running? Could you provide links to it's own docs so that we can expand on the examples you provide?

We upload AT Command pdf "ESP8266_AT_Instruction_set.pdf ", in our repository, go through this pdf.

Hmm.. not sure that this command set works fully with the onboard ESP8266 firmware.

AT+GMR
AT version:1.2.0.0(Jul  1 2016 20:04:45)
SDK version:1.5.4.1(39cb9a32)
Ai-Thinker Technology Co. Ltd.

OK

So it is using the Ai-Thinker firmware which doesn't appear to be as well documented for which Espressif commands are supported. e.g. AT+UART_CUR? and AT+UART_DEF? both give error:

AT+UART_CUR?

ERROR

Trying to set baud rate using "AT+UART_CUR=", "AT+UART_DEF=", and "AT+UART=" (this latter command is meant to be deprecated) also return an error.

AT+CWLAP is returning SSID's, but not a full list of those reported by other MCU's (e.g. WiMOS D1 Pro, ESP32 DevKitC V4), which may be antennae related - but could be comms related which is why I was looking at baud rate / buffer size / etc.

Quick check of commands to 'get' information show that the following also produce error message:

• AT+SYSRAM
• AT+SYSADC
• AT+SYSIOGETCFG

Haven't tried any other set commands yet (other than the AT+UART ones above).
