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...

Hello! I'm using an ESP-32 Cam board, and trying to get the CamWebServer example to work on it with the Arduino IDE. I don't have an adpater for USB so I've connected it to an Arduino Uno like you can see in the png attachement to this post. When I click to upload the ...
One of the ways to solve this is holding-down the “BOOT/FLASH” button in your ESP32 board while uploading a new sketch at the same time. But having to worry about this every time you want to upload new code can be tedious, specially when you’re testing and debugging your code....
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...
起初是由https://github.com/espressif/esp-qcloud中无法使用蓝牙配网,然后使用官方BLUFI示例尝试发现也无法成功配网。 ESP-IDF版本为4.3.4,使用的芯片为ESP32-C3FN4 更换过芯片以及分别在Android和iOS系统下进行BLUFI配网尝试,皆未成功,以下是bt_debug_log_level 使用verbose级别输出的日志内容 ...
hello, I have a esp32 devkit v1 of 30 GPIOs and I can not put any code on the board always gives me this error: "The fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header" I've already tried everything ... press the boot button when "Connecting...
