#69115 Hi
back again
i purchased a wifi module form Ebay about a week ago and it has yet to arrive.
My question here is, when i get this.
Without flashing out my wifi module is there a way to view the AT commands so that i can setup my wifi password and SSID of my modem/router.
Any suggestion
Thanks
Tony

#69134 I'm not sure what you mean by "View my AT commands", but if you want to know what AT commands are available in the default software, have a look at this document from Espressif. :idea:

Note: it's very likely your module has an older version of the firmware, so some commands are not yet implemented.
The document also described where to get the latest firmware if needed.

#69152 Hi
Thanks for the reply and documentation.
Maybe i should have worded it, how do i copy or save the default AT commands that comes already preloaded inside the microcontroller?
Does anyone know?

#69209 Do you mean: "How do I make a backup of the firmware already inside my ESP"?

Normally you wouldn't need to because the default firmware inside an ESP8266 is just Espressif's "NON-OS SDK", which you can download from the Espressif site.

However, it is possible to make a backup using ESPTool (esptool.py or esptool.exe), though I've never done it myself.
Do a search here on this forum; there are a few topics that describe how to do this. :idea:

If you're really stuck, I might be able to write a small tutorial, but please try yourself first.
