测试平台大概说明下， mde2.7 adk toolkit 1.2.10.21 ADK-21.4-CS-r00111.1
默认回连时间是10秒，这里可以修改为其他想要的值。 const sink_service_config_t sink_service_config =
{
.supported_profile_mask = (DEVICE_PROFILE_AVRCP|DEVICE_PROFILE_A2DP|DEVICE_PROFILE_HFP),
.profile_list = usb_dongle_config_profile_list,
.profile_list_length = ARRAY_DIM(usb_dongle_config_profile_list),
.page_timeout = APP_CONFIG_PAGE_TIMEOUT_S,
.rssi_pairing_params = &usb_dongle_config_rssi_params,
.max_bredr_connections = APP_CONFIG_MAX_BREDR_CONNECTIONS,
};
根据图片，修改source_apps\usb_dongle\src\usb_dongle_config.h文件 #define APP_CONFIG_PAGE_TIMEOUT_S 10 /*!< Maximum number of seconds to attempt reconnection to a previously paired sink. */
