but it seems like there is enough memory. I don't understand what I've done wrong.

function onInit() {

  I2C3.setup({sda:B4,scl:A8});
  var bh=require("BH1750").connect(I2C3);
  bh.start(3);
  
  var dht = require("DHT11").connect(B5);
  
  clearInterval();
  // initialise the ESP8266, after a delay
  setTimeout(function() {
    
    Serial1.setup(115200, { rx: B7, tx : B6 });
    wifi = require("ESP8266WiFi_0v25").connect(Seri­al1, function(err) {  
      if (err) throw err;
      console.log("Connecting to WiFi");
      wifi.connect("xxxx", "xxxx", function(err) {
        if (err) throw err;
        wifi.getIP(function(e,ip) {
          LED2.set();
          console.log(ip);
          setInterval(function() {
            dht.read(function (a) {
              sendForm(a.temp.toString(), a.rh.toString(), Math.round(bh.read()).toString());
            });
          }, 60000); // once a minute
        });
      });
    });
  }, 2000); 
}
