ESP8266 Community Forum

Hi: I am a mobile guy and have used other WIFI modules. For most there is some sort of a configuration procedure that I can use the module without a MicroController or other means.

1) Module goes into AP Mode
2) Mobile Device can connect and configure to the existing AP with SSID / Password, etc.
3) Module reboots and Mobile device connects to new IP under the existing AP

With looking over this module...

0C-ESP8266__WROOM_WiFi_Module_Datasheet__EN_v0.4

One has to download the AT command firmware (this would be ok), but then end user has to configure using UART and not the WIFI.

Maybe there is a way to write / change the firmware to automatically go into AP mode and accept AT commands to reconfigure?

If this has been discussed before, my apologies, just starting to get into this module.

Ok, I have the module up when setting

1) GPO0 high
2) GPO2 high
3) GPO15 Low

It goes into AP mode and shows up and can connect to WIFI ESP_xxxxx 192.168.4.1

Now is there a way to do telnet to 192.168.4.1 All attemps fail on common ports. It would be nice to configure this using telnet and AT.

So the question is does this ship with the AT functions?

I am getting a UART TO USB conversion board and will try that soon, but would like to be able to configure the unit on power up using WIFI / TCP / TELNET / etc.

AT firmware doesn't provide Telnet server by itself.
But you can install other firmware like https://github.com/jeelabs/esp-link, which provide Wifi-Serial bridge.
You can also create your own bridge using ArduinoESP.
