wifi settings on esp8266

Hi, please forgive me for my bad english.

I have several esp8266 running with espruino. All of them are running very well. But I'd like to permit to change the wifi settings over HTTP. I have one page (/) wher eI can put some fields like "ssid name", "ssid password". But I don't know how I can save these values in my program. I think that I have to change my program to get these value in memory, but I don't know if there is the good solution.

Is someone have an idea ?

Thanks.

For clarification, are you inquiring on how to dynamically save the 'ssid' and 'password' to memory after program start, and 'save()' from the WebIDE command line won't suffice?

r/w the SD card perhaps? http://www.espruino.com/Internet#line=20­,20,39,46,67,79,91,108

Yes it is exactly that. But I don't have any sdcard connected to the esp. The link provided explain how to save data to an sdcard. I just want to save 4 parameters on memory:

1 - default ssid in ad-hoc mod
2 - default password
3 - user ssid
4 - user password

If I use the code in link provided, is there a way to save the file in json format in memory of the esp ?

ESP8266_WifiUsage - wifi.save() - Wifi.save() (reference) may be the answer for you.

Hi @azer,

something like this ?

https://github.com/MaBecker/esp8266/blob­/master/Espruino/JoinWifi.js

just as a starting point and don't expect to much .....

After receiving the 'new' wifi connection configuration information, reset the ESP8266, connect with the new configuration, and when it successfully connected, then execute the Wifi.save(), otherwise re-connect with the 'old' info and perform defined number of retries - all programmatically in js (AT commands, etc).

Thanks for all of that. I'll try it this week :)
