espruino-cli - it doesn't detect the same ports as espruino web IDE

Hi,

I can successfully upload the code via Espruino Web IDE. The port I have to select on Web IDE is:
/dev/cu.wchusbserial1410

However if I run espruino --list I can't see that port, instead I see (among others /dev/tty.*) /dev/tty.wchusbserial1410 - however there is any /dev/cu.*)

Regardless the port I try to use cli upload doesn't work for me.
At times I am getting an info that the port was not found (although its on the list).

The full command I am running is:

espruino -v --no-ble -b 11520 -p /dev/tty.wchusbserial1410 --board ESP8266_4MB app.js

Manual board JSON load complete

and

espruino --list

PORTS:
  /dev/tty.usbserial-1420
  /dev/tty.wchusbserial1420

Any ideas ? Thanks.

Hi!
Possibly just a typo in the forum post, but may work checking:
-b 11520 << Should be 115200, a 0 is missing
You wrote wchusbserial1410, but the list shows wchusbserial1420 (10 vs 20 at the end)

Thanks @AkosLukacs
with the updates you mentioned (I wonder how I didn't noticed it before ?!) and installing serialport I am one step further.

Now the upload seems to load, but I am getting syntax error - probably because of my ES6 notation - do you know why I can't use ES6 if on web IDE it works fine ?

Don't know, can you post your code & the error you get?

// REQUIRE
const D1 = NodeMCU.D1;
const D2 = NodeMCU.D2;

const wifi = require("Wifi");

// CONSTS
const MQTT_SERVER_IP = "";
const SSID = "";
const PASS = "";

// FNS
const connectWifi = () =>
  new Promise((resolve, reject) => {
    wifi.connect(SSID, { password: PASS }, function(e) {
      if (e) {
        console.log("error during connect:", e);
        wifi.disconnect();
        reject(e);
      } else {
        console.log("connected to", SSID);
        wifi.stopAP();
        resolve(wifi);
      }
    });
  });

const connectDisplay = () =>
  new Promise((resolve, reject) => {
    console.log(1);
    I2C1.setup({ scl: D1, sda: D2 });
    console.log(2);
    // OLED driver and graphic library
    const g = require("SSD1306").connect(I2C1, () => {
      resolve(g);
    });
  });

let g = null;
const writeText = text => {
  g.clear();
  g.setRotation(2);
  g.setColor(1);
  g.setFontVector(15);
  g.drawString(text, 0, 10);
  g.flip();
};

const startApp = () => {
  connectDisplay()
    .then(newG => {
      g = newG;
      writeText("Init...");
    })
    .then(() => {
      return connectWifi();
    })
    .then(() => {
      writeText("Wifi - OK");
      const mqtt = require("MQTT").connect({
        host: MQTT_SERVER_IP
      });

      mqtt.on("disconnected", () => {
        writeText("Disconnected");
      });

      mqtt.on("connected", () => {
        writeText("MQTT - OK");
        mqtt.subscribe("wemos/#");

        const topic = "wemos/start";
        const message = "Demo!";
        mqtt.publish(topic, message);

        mqtt.on("publish", pub => {
           writeText(pub.message);
        });
      });
    })
    .catch(() => {
      writeText("Error!");
    });
};

//startApp();
E.on("init", startApp);
save();

Ok, got the error.

const connectWifi = () =>
  new Promise((resolve, reject) => {
    wifi.connect(SSID, { password: PASS }, function(e) {
      if (e) {
        console.log("error during connect:", e);
        wifi.disconnect();
        reject(e);
      } else {
        console.log("connected to", SSID);
        wifi.stopAP();
        resolve(wifi);
      }
    });
  });

has to be

const connectWifi = () => {
  return new Promise((resolve, reject) => {
    wifi.connect(SSID, { password: PASS }, function(e) {
      if (e) {
        console.log("error during connect:", e);
        wifi.disconnect();
        reject(e);
      } else {
        console.log("connected to", SSID);
        wifi.stopAP();
        resolve(wifi);
      }
    });
  });
};

difficult to track, because both formats are valid, and text editor can't catch the issue :/
