multi-platform bluetooth serial port library for C++

bluetooth-serial-port's Issues

if connect bluetooth device need password,how can i deal with it?

hi,professor:
like the topic said
please help!

CMake issues

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.

This appears while compiling.

Bluetooth server

Ok.

Thank you for the library!

I can connect with remote devices but is it possible to implement a bluetooth 'server' with bluetooth-serial-port? Remote devices open a connection with the local device.

I need to listen connections from remote devices...

cannot send data from pc to raspberry pi

i am connect pc to raspberry pi to send a message. but it can't read any character?

this is program from pi:

Where did I go wrong? Anyone can help?
Thank you.

can not connect to any device!

Hi,
It seems that DeviceINQ::SdpSearch() always fails (it returns -1 for all devices) .
I just ran test/main.cpp code and it lists all devices but with -1 for channels. So when I can't create a BTSerialPortBinding, because it needs positive channel id.

I have tested this on windows 7, VS 2015.

How to detect device disconnection

Is there is a function that checks if connection is still alive and device hasn't disconnected? (Windows)

inquiretest always throws Exception : cannot find service

Windows use of library

I am attempting to use this library in my project, how do I include it in my c++ project?
What I've tried:
Built the project using CMake - specifying the downloaded unzipped project as the source and another folder for the binary output.

My build output: http://i65.tinypic.com/2vmfu4o.png

I have built a .lib file and added it to Linker -> Input -> Additional Dependencies. Then I included the .lib file path directory, however when I try to #include "DeviceINQ.h" or #include I get an error can't find source file. I tried to view the contents of the .lib file in Visual Studio Command Prompt, this was the output:

http://i64.tinypic.com/1zvrivb.png

Here it shows that DeviceINQ is an object but I still cannot include the header file. Any Ideas, thankyou.

Linker Issues on Windows

Hello everyone,
I am having difficulties getting this library to work. I am currently using Visual Studio 2019. I have looked in a past thread about this same problem pretty much but when I followed that answer it did not work. My Errors:

Severity Code Description Project File Line Suppression State
Error LNK2019 unresolved external symbol "public: __thiscall DeviceINQ::~DeviceINQ(void)" (??1DeviceINQ@@QAE@XZ) referenced in function "public: void * __thiscall DeviceINQ::`scalar deleting destructor'(unsigned int)" (??_GDeviceINQ@@QAEPAXI@Z) PleaseSerialWork C:\Users\Swagm\source\repos\PleaseSerialWork\PleaseSerialWork\PleaseSerialWork.obj 1

Here is a bit more info.
(Additional Includes) : C:\Users\Swagm\bluetooth-serial-port\src

(Additional Libraries in Linker) : C:\Users\Swagm\bluetooth-serial-port\Debug\bluetoothserialport.lib

I have tried everything. I really hope I can get this working because this utility would be insanely useful for my current project. Thank you so much in advanced.

No devices found on raspberry pi

Hi, I got your code to compile on raspbian but I only get this output with the test

done, found 0 device(s)`

using hcitool I get this:

not able to compile code in mac

I tried to compile and run ur code . I am using cmake from macports. It is creating btscan and libbluetoothserialport.a. when I try to excute that
syntax error near unexpected token newline' ./libbluetoothserialport.a: line 1: !<arch>'

can u please help me how to make it work in mac. !!

Typo in readme

In README.md, it is

BTSerialPortBinding::IsDataAvailable(buffer, length)

In BTSerialPortBinding.h, it is

bool IsDataAvailable();
