EspruinoWifi + ESP8266 external board http server sends nothing

Hi Gordon,
thank you for your reply. There is no serial connection possible anymore (Over Serial2 --> Serial2.setup(9600, { rx: A3, tx : A2 });). Any AT+* command could not be sent to the board since there seem to be no connection.
I did not try to reflash the ESP8266 onboard module.(Is there a manual for that?)
Is there any documentation of how to connect the flow control to the external WiFi module?

The full code is as follows:

  Serial1.setup(115200, { rx: B7, tx : B6 });
  var esp8266 = require('ESP8266WiFi');
  
  console.log("Connecting to ESP8266");
  
  var wifi = esp8266.connect(Serial1, function() {
  console.log("Connecting to WiFi");
    wifi.reset(() => {
     /*Does not close all sockets, I assume --> CIPServer creation fails after some restarts of the Espruino*/
      console.log('Reset WiFi');
      console.log('Creating access point');
      wifi.createAP('BLA', '12345678', 1, 0, (err) => {
        if (err) {
          console.log('An error occured:');
          console.log(err);
          return;
        }
        
        console.log('Access Point created');
        
        require('http').createServer((req, res) => {
          req.on('end', function() {
            console.log('request stream end (http.incomingMessage stream)');
          });
          
          res.on('end', function() {
            console.log('response finish (http.serverResponse)');
          });
          
          req.on('close', function() {
            console.log('request close (http.incomingMessage)');
          });

          res.on('close', function() {
            console.log('response close (http.ServerResponse)');
          });
          
          console.log('Request Headers:');
          console.log(req.headers);
          console.log('Request Method:');
          console.log(req.method);
          
          var a = url.parse(req.url, true);
          res.writeHead(200, {'Content-Type': 'text/plain'});
          res.end(JSON.stringify(a));
        }).listen(80);
        
        console.log('Http server created');
      });
    });
  });
