WiFi + Bluetooth

Dug up the ESP8266 (black PCB) and connected it to a Pixl.js

This is the code I used to detect the baud rate, and this then get the hello page.

// blewifi.js
// Pixl - ESP8266 ESP-01

pinMode(D8 ,"output"); D8.set();
pinMode(D9 ,"output"); D9.set();
pinMode(D10,"output"); D10.set();
pinMode(D11,"output"); D11.set();
var serial=Serial1
  , pins={rx:D0,tx:D1}
  , baud=115200 // 76800
  , wifi,wifiMod=require("ESP8266WiFi_0v25")
//  Use ESP8266WiFi here  ^^^^^^^^^^^^^^^^ (and 9600 baud)
//  if you have an ESP8266 with firmware older than 0.25 (?)
  , WIFI_NAME="mySSID"
  , WIFI_PASS="myPassword"
  ;

function hello(altBaud) { // for run
  altBaud=altBaud||baud;
  serial.setup(altBaud, pins);
  console.log("Connecting to ESP8266");
  Terminal.println("Connecting to ESP8266");
  wifi=wifiMod.connect(serial, function(err) {
    if (err) throw err;
    console.log("Connecting to WiFi");
    Terminal.println("Connecting to WiFi");
    wifi.connect(WIFI_NAME, WIFI_PASS, function(err) {
      if (err) throw err;
      console.log("Connected");
      Terminal.println("Connected");
      // Now you can do something, like an HTTP request
      require("http").get("http://www.pur3.co.uk/hello.txt", function(res) {
        console.log("Response: ",res);
        res.on('data', function(d) {
          console.log("--->"+d);
          Terminal.println("--->"+d);
         });
      });
    });
  });
}

function pgm() {
  D9.reset();
  D8.reset();D8.set(); // reset
}

function test() {
  setTimeout(function() { test0(  9600); }, 4000);
  setTimeout(function() { test0(115200); }, 8000);
  setTimeout(function() { test0( 76800); },12000);
  setTimeout(function() { test0( 57600); },16000);
  setTimeout(function() { test0( 74880); },20000);
  setTimeout(function() { console.log("Done!"); },24000);
}

function test0(baud) {
  serial.removeAllListeners();
  var l="";
  serial.on('data', function(d) {l+=d;});
  serial.setup(baud, pins);
  D8.reset();D8.set(); // reset
  setTimeout(function(){
    serial.write("AT+GMR\r\n");
    setTimeout(function(){
      console.log(baud,":",JSON.stringify(l));
      Terminal.println(baud,":",JSON.stringify(l));
      },1000);
  },200);
}

After upload of the code, I enter in the IDE console: test().

And get this back:

>test()
=undefined
9600 : ""
115200 : "AT+GMR\r\r\nAT version:0.40.0.0(Aug  8 2015 14:45:58)\r\nSDK version:1.3.0\r\nAi-Thinker Technology Co.,Ltd.\r\nBuild:1.3.0.2 Sep 11 2015 11:48:04\r\nOK\r\n"
76800 : "\xAB\xE5\xF0"
57600 : "eEC\xF8"
74880 : "\xAA\xA5\xFD"
Done!

Because 'clear' shows with 115200 baud, I enter hello(115200), and get this back:

>hello(115200)

Unfortunately, I have no plain ESP-12X for testing, but I have another ESP-01 (blue PCB) with even older firmware. I'll try to update it. test() returns:

>test()
=undefined
9600 : "\xFE"
115200 : "\x10\2"
76800 : "\r\n ets Jan  8 2013,rst cause:2, boot mode:(3,6)\r\n\r\no"
57600 : "GDZ\x98Q(`\xC9h\v\xCC\xBB\xC9@Pu\xA8u\x1DP\x11\5T\xFD"

Done!

And it never got beyond Uncaught No 'ready' after AT+RST exception when connecting to the ESP8266 module, even though it worked when I used it 5+ years ago.

>hello(74880)
Connecting to ESP8266
=undefined
Uncaught No 'ready' after AT+RST

(PS: Screen shot of PixleJS w/ test() with a different sequence and no 74880 baud check.)
