====== Communication API ======
As API that configures the SSL communication, there are communication interfaces include LAN, USB, and RS485. To get real-time device connectivity and search results, please register the callback function via the [[BS2_SetDeviceEventListener]] function.

  * [[BS2_SetDefaultResponseTimeout]]: [+ 2.6.3] Sets default response timeout between device and server. 
  * [[BS2_GetDefaultResponseTimeout]]: [+ 2.6.3] Gets default response timeout between device and server. 
  * [[BS2_GetSocketRetryCount]]: [+ 2.9.1] Gets the setting value of the number of retries for read/write failures during Non SSL communication.
  * [[BS2_SetSocketRetryCount]]: [+ 2.9.1] Set the number of retries for read/write failures during Non SSL communication.

</code>
1. // OnDeviceFound // \\
Callback function that is called when a new BioStar device is found in Subnet. \\ \\
2. // OnDeviceAccepted // \\
Callback function that is called when the BioStar device requests a connection to the BioStar application. \\ \\
3. // OnDeviceConnected // \\
Callback function that is called when the device and the BioStar application are connected. \\ \\
4. // OnDeviceDisconnected // \\
Callback function that is called when the connection between the device and the BioStar application is lost. \\ \\
5. // OnAlarmFired // \\
Callback function that is called when an alarm set in the Zone occurs. \\ \\
6. // OnInputDetected // \\
Callback function that is called when an input signal is generated. \\ \\
7. // OnConfigChanged // \\
Callback function that is called when the configuration is changed by manipulating the terminal. \\
