  Thanks again.
  In fact I Added a"SoftwareSerial" TX function so that I can control several devices with one espruino . And it works amazingly well !

    function softwareSerialTX(pin, arr) { // 9600, 8N1
      var baud = 1000/9600;
      let i, j, len;
      let binArr = [];
  
      len = arr.length;
      for (i = 0; i < len; i++) {
        binArr.push(0);
  
        for(j = 1; j < 256; j *= 2) {
          binArr.push((arr[i] & j) ? 1 : 0);
        }
  
        binArr.push(1);
      }
      binArr.push(0);
  
      let pulseArr = [];
      let start = binArr[0];
      let v = start;
      let cnt = 1;
  
      len = binArr.length;
      for (i = 1; i < len; i++) {
        if (binArr[i] == v) {
          cnt++;
        } else {
          v = binArr[i];
          pulseArr.push(cnt*baud);
          cnt = 1;
        }
      }
      if (cnt) {
        pulseArr.push(cnt*baud);
      }
  
  //console.log(arr);
  //console.log(binArr);
  //console.log(pin);
  //console.log(start);
  //console.log(pulseArr);
  
      digitalPulse(pin, start, pulseArr);
    }

  Amazing :)
  That totaly solved the issue, thanks !

  var id = 1;
  Serial1.setup(9600, { tx: B6, rx: B7});
  Serial1.write([0x7E,0xFF,0x06,0x03,0x00,­0x00,id,0xEF]);

  Hello !
  I'm trying to control a SerialMP3 board but each time I send a command my espruino WiFi is disconnected from the USB console

  var id = 1;
  Serial1.setup(9600);
  Serial1.write([0x7E,0xFF,0x06,0x03,0x00,­0x00,id,0xEF]);
  

  Any idea ?
