Localhost (127.0.0.1) is your PC. You need to have specific IP address assigned to your ESP32 device and specific IP address in the same subnet assigned to your PC to be able to communicate. Also, there is no IP address allocated to the ESP board when I connect it to my PC, however...
针对你遇到的“failed to connect to esp32-s3: no serial data received”问题,以下是一些可能的解决步骤,帮助你逐一排查并解决问题: 检查ESP32-S3与电脑的连接 确保ESP32-S3开发板通过USB线正确连接到电脑。 检查USB线是否完好,无破损或松动。 确认串口驱动已正确安装 对于Windows系统,通常需要安装CP210x或CH...
ESP32 无法烧录程序,报错:Failed to connect to ESP32: No serial data received.且开发板上电EN脚不是高电平的解决方法。 参考:【ESP32烧录异常解决办法-哔哩哔哩】 https://b23.tv/wH0FULt 结论:拉高EN脚电平,上电,拉低BOOT脚电平,开始烧录,拉低EN脚电平,烧录结束 原因分析:由于近期看到了很多使用ESP32...
看了一下显示的log信息，貌似题主已经上传成功了，通常来说烧录之前要先保证你的硬件下载电路以及驱动没有问题，把你的板子连接到电脑上面然后打开设备管理器查看串行设备有没有具体设备型号显示，确保这一步没问题之后，检查自动下载电路是否有问题，esp32烧录时需要对IO0进行上下拉操作，做好这些一般来说就都没问题...
