[Solved] ESP8266 problem on Espruino pico

Ok, something is odd here, are you sure it's the code you posted earlier:

var delay=5000;
Serial2.setup(9600, { rx: A3, tx : A2 });
var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
  if (err) throw err;
  wifi.reset(function(err) {
    if (err) throw err;
    console.log("Waiting for ESP8266 to flush its serial buffer");
    setTimeout(function(){
      //your code to be executed after 1 seconds
      wifi.connect("solarsystem","tmpjoimc", function(err) {
      if (err) throw err;
      console.log("Connected");
      // Now you can do something, like an HTTP request
    }); //wifi.connect
    }, delay); //setTimeOut
  }); //wifi.reset
}); //require

Because Espruino seems to be trying to reset and connect twice in a row from the log you posted...
