根据您提供的日志,我能看到以下事件序列:
1. 开机启动,加载应用程序,并初始化蓝牙设备(ESP_BT_L2CAP_INIT_EVT)。 2. 蓝牙L2CAP服务启动成功(ESP_BT_L2CAP_START_EVT)。 3. 蓝牙SDP服务初始化成功(ESP_SDP_INIT_EVT)并创建记录完成(ESP_SDP_CREATE_RECORD_COMP_EVT)。 4. 手机P30尝试与设备进行蓝牙连接,连接成功(hcif conn complete)。 5. P30请求进行身份验证,身份验证成功(authentication success)。 6. P30主动断开蓝牙连接(hci cmd send: disconnect)。 通过日志,可以看到P30和ESP32成功建立了蓝牙连接并进行了身份验证。但是之后P30主动断开了蓝牙连接,原因是hci cmd send: disconnect,其中rsn:0x13代表"Remote User Terminated Connection",表示蓝牙连接被远程用户终止。 通常情况下,蓝牙连接被断开的原因可能包括以下几点: 1. 蓝牙协议栈配置问题:请确保应用程序正确地配置了蓝牙协议栈,包括正确的服务、特征值等配置。 2. 通信稳定性问题:检查应用程序的通信过程是否稳定,是否出现通信错误或异常。 3. 超时问题:某些情况下,蓝牙连接可能会因为超时而断开,例如连接超时、认证超时等。可以检查蓝牙连接时的超时设置。 4. 资源问题:确保设备有足够的资源来维持蓝牙连接,包括内存、CPU资源等。 5. 驱动或固件问题:请确保设备上使用的蓝牙驱动和固件是稳定和适配的版本。 为了更好地理解问题,建议您检查您的应用程序代码,并查看在断开连接时是否有相关的错误或警告信息。另外,查阅蓝牙协议栈和相关库的文档,以确保您的蓝牙连接的配置是正确的。 |
