Error when using Ethernet with ESP32

Hello, recently I downloaded the basic routine of the official Ethernet. I set the Ethernet in the configuration as the internal Ethernet controller LAN87XX. 2.png On the hardware, we use ESP32 as the main control MCU, LAN8720A chip to control Ethernet, and FC-13ENL as the network port. The software...

Error occurred when using JTAG to burn the program to ESP32:libusb_handle_events() failed with LIBUSB_ERROR_IO

Hi Team The JTAG debugger I used was espressif's official ESP-PROG, the compilation software was VSCODE, and the connection confirmation was in accordance with TMS-TMS,TDI-TDI,TCK-TCK and TDO-TDO connections. I am trying to use JTAG to burn the ESP32 program, but the following error occurs. How to s...

关于ESP32使用以太网时出现的错误

各位大佬好,近日我烧录了官方以太网的basic例程, 14ce1c806ef991178d2fd4ddf96c9c82.png 我将配置中的以太网设置为内部以太网控制器LAN87XX, f08279b04a0791f490d907b0ce108de2.png 但遇到了lan87xx: lan87xx_init(299): wrong chip OUI 和 esp_eth: esp_eth_driver_install(229): init phy failed的问题, 13624b12e2961a98bd89b62703c910be.png 请问该如何解决这个问题呢?

Increase the number of BLE Bluetooth connected devices for ESP32

Hello, when I used arduino to increase the number of Bluetooth connections of ESP32, I found that the maximum number of connections can only reach 4, which is not consistent with the official document that the maximum number of connections is 9. I changed the time the four devices I could connect to...

Arduino环境下实现ESP32-C3不关闭BLE进入light-sleep睡眠模式

大佬们好,近日在学习关于ESP32-C3的Light-sleep模式时产生了一些疑惑,想向各位请教: 我想实现的时 ESP-C3进入Light-sleep后BLE连接不会断开,以下是实践时遇到的问题: ESP-C3进入Light-sleep时BLE会被断开,我在官网上查到如果想保持BLE连接需要启用自动Light-sleep模式(图1), 1.png 我在这里找到了如何启动自动Light-sleep模式(图2), 2.png 但是当我使用时它会显示“该函数未定义的错误,于是我又找到了这个电源管理锁企图锁住BLE不被睡眠状态影响(图3), 3.png 但是我使用上图这个方法BLE依然会断开,然后...
