Use BTstack to implement communication between IOS devices and non-IOS devices

Google BTstack address: http://code.google.com/p/btstack/

Usage: http://code.google.com/p/btstack/wiki/GettingStarted

Steps:

1. Use Cydia to install BTstack on IOS devices and search for it to install it;
2. Get the BTstack project from the Google code SVN: get the project from Google's SVN code server, SVN Location is Repository. Svn checkout http://btstack.googlecode.com/svn/trunk/ btstack
3. Go to the downloaded BTstack folder.
4. Run bootstrap helper
5. Configure BTstack for the iPhone if you have sdks 2.0 installed, or... configure BTstack for the iPhone. Note that the version here is IOS5.0. You should change the version value based on your actual situation.

   After configuration, you can directly run the project. Go to BTstack/CocoaTouch/, run the project, and find the surrounding non-IOS devices.

   BTStack engineering interpretation, engineering framework:

   The BTDevice Class mainly represents a bluetooth device and contains common Bluetooth information (such as name, address, and Class );

   The BTDiscoveryView class mainly provides a search interface;

   The BTstackManager class is mainly used to manage Bluetooth devices.

   BTTeststackManager is used for testing. The BTTeststackManager. m code and interpretation are as follows:

   # Import "TestBTstackManager. h"
   # Import <BTstack/BTDevice. h>
   
   
   @ Implementation TestBTstackManager

   Note: This project must be debugged on the device. It cannot be debugged on the simulator!
