ESP8266 Community Forum

My no-name ESP8266 module give AT version:1.3.0.0(Jul 14 2016 18:54:01) / SDK version:2.0.0 for the AT+GMR command.

My first question is - is there a list of AT commands for each AT version? And can I assume that my 8266 module wouldn't be "missing" any commands?

My second question - what are the AT commands (assuming version 1.3.0.0 has them) to set the various parameters and operating modes of the AT pins? I'm having a hard time finding example AT command sequence to get, say, IO pin 0 to go high or low on command.

I've seen mention of AT+SYSGPIOREAD (with no other parameters or variables?) - my module just gives an error when I give it that command.

Not related to IO functions, but when I issue this command: AT+SYSRAM? I also get an ERROR. It's frustrating to see documented AT commands giving ERROR like this.

Wow. This forum is really useful. Well, I'll answer my own question. The AT command set is garbage. NODEMCU is too complicated to use easily. I burned something called ESPEasy firmware into my 8266 thing and can now easily set GPIO outputs with an easy HTTP command to the module.

It actually is, but there's no sense in 10 people replying to a thread with "I don't know, since the AT command set is useless".
Only a few (lets say 1%) amongst us actually use or have any real experience with the standard AT command set.
Since only a handful of the registered users here respond to messages, that 1% of them equals virtually 0.

To be honest: I actually did search the AT documents and replied to your question, but I never pressed the submit-button.
It wouldn't have added something useful to your thread and I had to get on with my daytime (and paid) job.

Okay, so you've figured it out yourself already; it's only written over a hundred or so times on this forum.

Supposedly there are commands - such as:

AT+SYSIOSETCFG —Configures IO Working Mode
AT+SYSIOGETCFG —Checks the Working Modes of IO Pins
AT+SYSGPIODIR —Configures the Direction of a GPIO
AT+SYSGPIOWRITE —Configures the Output Level of a GPIO
AT+SYSGPIOREAD —Reads the GPIO Input Level

But I can't get them to work - I always get ERROR response.
