Bluetooth communication between macOS and Ganglion with C++

trav

I am curious if anyone has any experience and luck successfully using C++ to create a central and a peripheral relationship with Mac.

I am trying to build a terminal application in C++ that searches for the Ganglion, connects and receives the array of objects from the Ganglion board.

So far the Apple docs seem to be more angled for IOS development .

I have found the headers which compiles , but unable to find actual functions to implement the logic needed to search, connect , communicate

#include <IOKit/hid/IOHIDLib.h>

#include <CoreFoundation/CoreFoundation.h>

#include <IOKit/IOReturn.h>

#include <IOKit/IOTypes.h>

#include <IOBluetooth/IOBluetoothUserLib.h>

#include <IOBluetooth/IOBluetoothUtilities.h>

#include <CoreFoundation/CoreFoundation.h>

Has anyone encountered this before? I am almost leaning towards just using the Qt framework since it has built in bluetooth libraries which does what I want but wanted to stay away from any framework or overhead

Here is a macOS Bluetooth heart rate monitor, sample app code. I've compiled this in the past and it ran.

Hey thanks so much again for the reply ! I am excited to check it out!

I just looked at the thread title again "with C++". Remember that Apple does not use C++, but instead Objective C, and more recently Swift. But this example is in Obj-C.

I read it through, would it be wise just to utilize Qt's built in bluetooth library in their framework ? instead of trying to find a work around with Xcode and C++? Thanks for your response

If you just want something more command line oriented, Python is already working,

Umm, but unclear if this runs yet on macOS. Seems like it would be much faster to apply whatever tweeks needed for macOS, than to code from scratch in C++. Especially if you just want command line / shell access.

Thank you, I appreciate your recommendation(s) I have been playing with my Arch Linux the last few hours and have got a decent bluetooth library that seems to accomplish what I'm going for. I have saw windows bluetooth libraries on google in which people were trying to accomplish something similar to my goal which appears to be quite straight forward, it seems the MacOsx in this context may not be the best OS to accomplish the task on at least when dealing with bluetooth although I should mention that Qt framework with C++ elegantly has their own libraries but also lingo.
