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
Connecting to '/dev/tty.wchusbserial1410'
Noble: getPorts - disabled
No navigator.bluetooth - Web Bluetooth not enabled
Port "/dev/tty.wchusbserial1410" not found - checking ports again (2 attempts left)

Port "/dev/tty.wchusbserial1410" not found - checking ports again (1 attempts left)
Noble: getPorts - disabled
Port "/dev/tty.wchusbserial1410" not found

and

espruino --list

Espruino Command-line Tool 0.1.27
-----------------------------------

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?

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 :/
