ESP32 BLE Arduino编译报错：'ringbuf_type_t'未声明

已安装Arduino IDE及ESP32 BLE Arduino库（版本1.0.1），打开「文件>示例>ESP32 BLE Arduino>BLE_notify」示例代码，选择ESP32 Dev Module开发板编译时触发错误，错误信息如下：

Compilation error: exit status 1

解决步骤 #

• 更新ESP32核心库：该错误源于ESP32 BLE Arduino库与ESP32核心库版本不兼容。打开Arduino IDE，进入「文件>首选项」确认ESP32开发板管理器URL已添加，再通过「工具>开发板>开发板管理器」搜索「ESP32」，将其更新至最新稳定版。
• 替换或更新BLE库：卸载当前1.0.1版本的ESP32 BLE Arduino库，安装该库的最新版本；或直接使用ESP32核心库自带的BLE功能，无需额外安装第三方BLE库。
• 清理冗余库：检查Arduino库文件夹，删除重复的BLE相关库，避免版本冲突后重新编译。
