HarmonyOS Next中SPP蓝牙连接报错2900099通常与底层协议栈异常有关。该错误表明蓝牙服务在建立RFCOMM通道时失败，可能由以下原因导致：
- 设备兼容性问题，部分旧设备不符合鸿蒙的蓝牙协议规范；
- 系统资源冲突，当多个应用同时请求蓝牙服务时可能触发；
- 协议参数不匹配，如UUID配置错误。
可通过adb日志查看具体握手失败阶段，需重点检查蓝牙适配器状态和配对信息缓存。
从日志分析来看，2900099错误是SPP连接过程中出现的常见问题。以下是关键点分析：
- 错误原因：
- 失败日志显示"Connect error 2900099"，这是蓝牙底层连接失败的标准错误码
- 对比成功和失败日志，主要差异在于连接阶段是否成功获取到有效的socket fd(190)
- 可能原因：
- 蓝牙设备未正确配对或配对信息已失效（虽然日志显示pairState=2已配对）
- 设备蓝牙服务未正常启动或UUID不匹配
- 射频干扰导致连接不稳定
- 建议检查：
- 确保设备已完全配对（不只是系统级配对）
- 检查UUID是否与设备端严格一致（当前使用默认SPP UUID）
- 添加重试机制，捕获2900099错误时自动重连
- 检查设备是否支持secure连接模式（当前设置为true）
临时解决方案可以增加重试逻辑：
let retryCount = 0;
const maxRetries = 3;
const connectWithRetry = async (option) => {
try {
await connect(option);
} catch (err) {
if (err.code === 2900099 && retryCount < maxRetries) {
retryCount++;
await new Promise(resolve => setTimeout(resolve, 1000));
return connectWithRetry(option);
}
throw err;
}
};
