Cpp-CLI_wrapper_Bluetooth_SDP

C++/CLI wrapper of Bluetooth_SDP_data_DLL for C# and .NET.

Here you have managed code (APIs) from native C++ unmanaged code (APIs).

How to use it

Included headers and libraries for using dll

  • stdio.h
  • vector
  • iostream
  • winsock2.h
  • bthdef.h
  • bthioctl.h
  • functional

DLL, lib and header

Before you can use this project, you must add to your project (it must be the same build type, example: Debug x64):

  1. header:

copy ioctl_data.h from Bluetooth_SDP_data_DLL to this project

#include "ioctl_data.h"

  1. .lib file:

copy .lib from Bluetooth_SDP_data_DLL to this project

#pragma comment(lib, "SDP_data.lib")

  1. .dll file:

Add SDP_data.dll into folder where .dll of this project will be with the same type of system (example: x64 Debug)

Functions

DLL wrapper have next functions:

Connection and disconnection functions

  • void CLI_connectToDevice(System::String^ str)

With this function you will connect to local bluetooth radio input parameter: System::String^ str (for example: "\\?\GLOBALROOT\Device\USBPDO-4") (you need physical device object name of Generic Bluetooth Radio)

  • void CLI_closeConnectionToDevice()

with this function you will close connection to local bluetooth radio (YOU MUST CALL THIS before app is closed!!!)

Search and retriving data functions

  • void CLI_SDPsearch(System::String^ str)

Here you can search for service data of remote bluetooth device input parameter: System::String^ str (you need bluetooth address of remote bluetooth device) (for example: "A8:B8:6E:E7:5A:B6")

  • void CLI_getBthDeviceInfo()

Here you will get list of all remote devices from previous search

  • void CLI_getLocalBthInfo()

here you will get data of local bluetooth radio

Reset functions

  • void CLI_reset_SDP_service_for_search()

Here you will set all service to false for search

  • void CLI_reset_attr_search_for_service()

Here you will set all attributes to false for search

Set/Dsiable functions

  • void CLI_set_all_SDP_service_for_search()

Here you set all services to TRUE for search

  • void CLI_set_SDP_service_for_search(Int16 service, int OnOff)

Here you set specific service to TRUE or FALSE for search

  • void CLI_set_all_attr_of_SDP_service_for_search()

Here you can set all atrributes for search

  • void CLI_set_default_attr_of_SDP_service_for_search(Int16 attr, int OnOff);

Here you can set only default attribute to TRUE or FALSE for search

Here you can set for all specific attributes of service to TRUE or FALSE for search

  • void CLI_set_all_default_attr_print(int onOff)

Here you can set all default attributes to TRUE or FALSE for print in console

  • void CLI_set_all_specific_attrs_service_print(Int16 service, int onOff)

Here you can set all service specific atrributes to TRUE or FALSE for print in console

  • void CLI_set_default_attr_print(Int16 def_attr, int onOff)

Here you can set default attribute to TRUE or FALSE for print in console

  • void CLI_set_specific_attr_service_print(Int16 service, Int16 attr, int onOff)

Here you can set service specific attribute to TRUE or FALSE for print in console

How to use it on client app

You have more options:

  1. option

in project add as new reference for "Cpp-CLI_wrapper_Bluetooth_SDP.dll" and copy&paste "CompanyIdentfiers.cvs", "SDP_data.lib" and "SDP_data.dll"

  1. option

copy&paste "Cpp-CLI_wrapper_Bluetooth_SDP.dll", "SDP_data.lib" and "SDP_data.dll" and "CompanyIdentfiers.cvs" to your app project

Examples

Connection and disconnection from local radio

Code

// 1. you must create class instance
CLI_DEFAULT_DATA data = new CLI_DEFAULT_DATA();
// 2. call CLI_connectToDevice to connect to local bluetooth radio
data.CLI_connectToDevice("\\\\?\\GLOBALROOT\\Device\\USBPDO-4");
// 3. close the connection
data.CLI_closeConnectionToDevice();

Getting list of previously searched devices and export/print data

Code

// 1. you must create class instance
CLI_DEFAULT_DATA data = new CLI_DEFAULT_DATA();

// 2. call CLI_connectToDevice to connect to local bluetooth radio
data.CLI_connectToDevice("\\\\?\\GLOBALROOT\\Device\\USBPDO-4");

// 3.1 if you want to print it in console you must set
data.sdp_settings.print = 1;

// 3.2 calling driver to return list of devices
data.CLI_getBthDeviceInfo();

// 3.1.1 or if you have disabled data.sdp_settings.print you can use
// data.cached_devices.print();

// 3.3 exporting data
Console.WriteLine("{0}",data.cached_devices.devices[0].name);

// 4. close the connection
data.CLI_closeConnectionToDevice();
