如果ESP32是通过编程运行的,检查编写的代码是否有语法错误、逻辑错误或其他问题。 尝试简化代码并逐个功能进行测试,以确定问题所在。 ESP32进入下载模式: 对于某些ESP32开发板,需要将其置于下载模式才能连接。通常,这需要将GPIO0引脚接地(GND),并在上电时保持该状态。 确保在连接和上传代码时,GPIO0引脚已正确接地。
经过查询后了解到,ESP32开发板在使用串口烧录程序的时候需要进入烧录模式,也就是需要将默认高电平的IO0端口电压拉低。一般只要按下开发板上面的BOOT键就可以了,但是经过实践发现并不行,于是我在网上找到了相应的解决方法:【ESP32烧录异常解决办法-哔哩哔哩】 https://b23.tv/wH0FULt。按照UP主文中所说的话:ESP3...

Right now I am starting up my esp32-c3 in APSTA mode using esp-idf. This serves a captive portal where a user can select a wifi network and connect to it, similar to how tasmota and wifimanager work. I am able to connect to a network if I call esp_wifi_stop();, then reconfigur...

I am trying to connect my ESP32 device (OLIMEX ESP32-POE-ISO-EA-IND) to my PC (host machine) with Ethernet. I have looked to examples (eth2ap and tcpclient) and was able to install the ETH driver and also attach the ETH to netif using esp_eth_new_netif_glue(). But I am not...
