Hi,

please help me with loading espruino code from flash after reset() or power-on device esp8266 12f.

My device has espruino ver. 1.89 and I need start http server after reset() or power-on.

Are you trying something like this ?

I don't know how onInit() works.

Hi @jakub.frydrych

o setup wifi as station connected your access point (only once)

var Wifi = require("Wifi");
Wifi.connect( "your SSSID",{password:"your password"}, function(err) {
    if (err) {
        console.log("error connecting to your SSID:",err);
    }
    else {
        Wifi.stopAP();
        Wifi.setConfig({powersave : "none"});  // optional    
        Wifi.save();  // this saves all your Wifi settings
        console.log("Wifi.getIP:", Wifi.getIP());
     }
}

o write code you want to be started on boot='init' and upload

E.on('init', function() {
	  // add your code here
	  ......
});

o after your code is completely uploaded run save, this will save, restart and run your code

save();

Hi, thaks for answear.

I test this tip and after restart device ( use func reset() ), device not loaded code from init function. What I do wrong ?

Testing code for init func :

E.on('init', function() {
      console.log("Device started");
});

And console output, after save(); code correctly loaded, but after reset() not load code from init function. If I call load() func after reset, code correctly run.

So it works as designed.

A reset() is not a boot, it is a soft reset that clears code.

A boot is when pressing reset button or call require("ESP8266").reboot

Many thanks,

I did not understand reset() func and take this func as restart device with boot.

Now is after reboot or power-on code loaded from memory.

Thanks for explanation and your time.
