• Espruino keeps disconnecting

  Hello, I have a problem with Espruino Pico on Mac.
  When I plug it in, red light flashes and then nothing flashes.
  When I connect espruino tty.usbmodem1 it connects and after a while it disconnects.
  When I want to connect it again, connection options state tty.usbmodem2 and again disconnects.
  I tried to reflash the firmware (with success) but still the same.

  Sometimes it writes this log:

  Connected
  >es from flash...
  >Console Moved from Serial1
  >
  =undefined
  >echo(0);

• Pico and ESP8266

  Hello friends. I have a problem with

  Uncaught No 'ready' after AT+RST
   at line 2 col 18
    if (err) throw err;
  

  Serial2.setup(115200, { rx: A3, tx : A2 });
  var wifi = require("ESP8266WiFi_0v25").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","WPA2_Key", function(err) {
        if (err) throw err;
        console.log("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);
          });
        });
      });
    });
  });
  

  When I was testing baud rates, only reasonable output was:

  AT+GMR\r\r\nAT version:0.21.0.0\r\nSDK version:0.9.5\r\n\r\nOK\r\n
  

  What am I doing wrong? Red light is on. When I removed the "if(err) throw err;" the script continues and Blue light is sometimes blinking (when trying to connect)

  What about HM-11 board? Iam using B6,B7 for TX,RX. But do I need the system key to solder (HM11 pin 16) with A8? (http://www.elecrow.com/download/bluetooth40_en.pdf)

  Edit:I tried with A8 but It seems I cant connect to the bluetooth module. When I try to connect to tty.Bluetooth-Incoming-Port, I cant write any command :/
