Code upload problem to ESP32

[shydr15]

Hi,

I have developed custom ESP32 board and GUI to upload code to my board. I am using Node serial port to connect to my device. When I establish connection to my ESP32 board in my GUI and press reset button on my board, error appears on my serial monitor stating "rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2)) waiting for download". I have read similiar posts here, where making hupcl as false was suggested as solution. I tried this solution and resetting the board worked as expected, but this time I was not able to upload code to my board. When I use another IDE (for example, Thonny IDE), I can easily upload code or reset my system, so I think this problem is related to my GUI.

Could you please help me to solve this issue? Thank you in advance,

OS: Windows

const` port = new SerialPort.SerialPort( {
                path: peripheral.path,
                baudRate: peripheralConfig.config.baudRate,
                hupcl:true,
                autoOpen: false,

            });  

port.open(error => {
                    if (error) {
                        if (afterUpload === true) {
                            this.sendRemoteRequest('peripheralUnplug', null);
                        }
                        return reject(new Error(error));
                    }

                    this.peripheral = port;
                    this.peripheralParams = params;

                    // Scan COM status prevent device pulled out
                    this.connectStateDetectorTimer = setInterval(() => {
                        if (this.peripheral.isOpen === false) {
                            clearInterval(this.connectStateDetectorTimer);
                            this.disconnect();
                            this.sendRemoteRequest('peripheralUnplug', null);
                        }
                    }, 10);

                    // Only when the receiver function is set, can isopen detect that the device is pulled out
                    // A strange features of npm serialport package
                    port.on('data', rev => {
                     
                       this.onMessageCallback(rev);
                      
                    });

                    resolve();
                

                });
