大家好、Gokulnath、

您应该能够使用 SPP_Data_Write 实现功能：

/*! @brief The following function is responsible for Sending Serial Data to
    * the specified Serial Connection.  The SerialPortID that is passed
    * to this function MUST have been established by either Accepting
    * a Serial Port Connection (callback from the SPP_Open_Server_Port()
    * function) or by initiating a Serial Port Connection (via calling
    * the SPP_Open_Remote_Port() function and having the remote side
    * accept the Connection). @param BluetoothStackID The input parameters to this function are
    * the Bluetooth Stack ID of the Bluetooth Stack that the second parameter is valid for.
    * @param SerialPortID Serial Port Identifier.
    * @param DataLength the Length of the Data to send.
    * @param DataBuffer A pointer to the Data Buffer to Send.
    * @return This function returns the number of data bytes that were successfully
    * sent, or a negative return error code if unsuccessful.
    * \note If this function is unable to send all of the data that
    *          was specified (via the DataLength parameter), this
    *          function will return the number of bytes that were
    *          actually sent (zero or more, but less than the DataLength
    *          parameter value).  When this happens (and ONLY when
    *          this happens), the user can expect to be notified when
    *          the Serial Port is able to send data again via the
    *          etPort_Transmit_Buffer_Empty_Indication SPP Event.  This
    *          will allow the user a mechanism to know when the Transmit
    *          Buffer is empty so that more data can be sent.

2.如果您使用最新的 Bluetopia 5.1栈和我们 的控制器子系统认证来获得 CC2564C、则您的器件将获得蓝牙5.1认证。

我们在 STM32上为 Noos 和 FreeRTOS 提供蓝牙5.1堆栈。 当下载内容在本周晚些时候更新时、您可以在该链接中找到该下载内容。
