    Salut @azer, what's your status?

    Great! I'll try this solution first then.

    It is soldered with the shim. Everything is going to be ok :)
    But maybe I should order a backup Espruino and ESP, just in case...

    Thanks. The USB TTL should arrive soon.
    Gordon wrote it is "quite difficult". Does he mean complex or risky (big chance of frying something)?

    I'm ordering a USB-TTL converter and will upgrade. Thanks. I read the ESP page too fast:

    If you don't have the 0018000902-AI03 firmware version, make sure you
    change the baud rate and Module Name in the code examples below.

    So I concluded that it was all right for me.

    But now I see in the table is written for 0018000902-AI03:

    This was the version sent on boards that came with the Espruino Pico
    KickStarter. It's quite old now, and is known have quite a few bugs.

    Thank you @DrAzzy

    Hi,

    I am still trying to have my Pico+ESP8266 act as simple HTTP server. It has been working last week (inconvenient of having this only as a hobby project :/ ) but now I keep getting this error.

    I used http://www.espruino.com/Interactive+Web+­UI to kick start my code. It still is pretty close to it. The first request I make works, but the second always triggers this error:

    Here, as seen in the Web IDE's console:

    GET /
    GET /
    ERROR: Socket error -1 while sending
    Uncaught Error: > not registered at line 2 col 64 ...Error(key+" not
    registered");
    ^
    in function "unregister" called from line 7 col 26
    at.unregister('>');
    ^
    in function "callback" called from line 4 col 40
    if (callback && (n=callback(d))) {
    ^
    in function "lineCallback" called from line 29 col 27
    lineCallback(l);
    ^
    in function called from system

    Code:

    var wifi;
    
    function connectWifi(){
      
      Serial2.setup(9600, { rx: A3, tx : A2 });
      
      wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
        if (err) throw err;
        wifi.reset(function(err) {
          if (err) throw err;
          console.log("Connecting to WiFi");
          wifi.connect(WIFI_NAME, WIFI_PASS, function(err) {
            if (err) throw err;
            console.log("Connected");
            // print IP address
            wifi.getIP(console.log);
            // Create a server
            require("http").createServer(pageHandler­).listen(80);
          });
        });
      });
      
    }
    
    
    function pageHandler(req, res) {
      console.log(req.method,req.url);
      if (req.method=="POST") {
          res.writeHead(200);
          res.end('POSTHOME');
      } else if (req.method=="GET") {
        if (req.url=="/") {
          res.writeHead(200);
          res.end('GEThome');
        } else {
          res.writeHead(404);
          res.end("404: Not found");
        }
      } else if (req.method=="OPTIONS") {
        if (req.url=="/") {
          res.writeHead(404);
          res.end();
        }
      }
    }
    
    connectWifi();
    

    I spent several hours looking for the origin of the error, as well as its cause with no luck. Does someone recognise it?

    res.on('close', fn) works. Thank you @Gordon.
