24  * to support service publishing and data transmission.
33  * @brief Declares unified data transmission interfaces.
35  * This file provides data transmission capabilities, including creating and removing a session server,
36  * opening and closing sessions, receiving data, and querying basic session information. \n
37  * You can use the interfaces to transmit data across the nearby devices that are discovered and networked.
275  * When a session is opened or closed, or there is data to process, the related callback is invoked.
308      * @brief Called when data is received.
310      * This callback is invoked to notify that data is received.
313      * @param data Indicates the pointer to the data received.
314      * User-defined data type, users should apply for memory by themselves.
315      * @param dataLen Indicates the length of the data received.

335      * @brief Called when stream data is received.
337      * This callback is invoked to notify that stream data is received.
340      * @param data Indicates the pointer to the stream data received.
341      * @param ext Indicates the pointer to the extended service data received.
342      * @param param Indicates the pointer to the stream data frame information.
