I used Strings.exe by Mark Russinovich to find every string in two firmwares.

The first one is the on in the file ESP_8266_BIN0.92.bin and I found these commands


The cloud update site is iot.espressif.cn

The second one is the v0.9.5.2 AT Firmware.bin by AI-THINKER (AT version:0.21.0.0 SDK version:0.9.5 using AT+GMR)
It has a lot of commands



but some of them seems not work like +PING.
The cloud update site is iot.vowstar.net but when updating from there my module start printing symbols in UART and I have to reflash to recover it

Those symbols may be telling you to change the baudrate. Am I wrong?

I checked different baud rates without any success!
I believe that I get the same error described here

Here is a text document explaining all the AT documents in V0.9.5.2 it is in chinese but if you use google translate it is useful!
