how to get list of bluetooth devices using ExternalAccessory.framework not using Gamekid framework, core bluetooth framework. please write me examp0le of code

Answer 1

The External Accessory framework is only get list apple devices…By Apple

The External Accessory framework is designed to allow iOS applications
to communicate only with hardware accessories that are developed under
Apple’s MFi licensee program. MFi compliant accessories can be
implemented as wired devices, meaning they plug in to the iOS device’s
30-pin connector, or as wireless devices, whereby they use Bluetooth
as the communication channel. Either way, an application that uses the
External Accessory framework will not be notified of an accessory’s
presence unless the accessory identifies itself as being MFi
compliant, i.e., it was specifically designed to interface with an iOS
application.

if you want get the list only apple device use sample code

NSArray *accessories = [[EAAccessoryManager sharedAccessoryManager] 
                        connectedAccessories]; 
for (EAAccessory *obj in accessories)
{ 
    NSLog(@"Found accessory named: %@", obj.name);
}

you must include the UISupportedExternalAccessoryProtocols key in your app’s Info.plist file.

<key>UISupportedExternalAccessoryProtocols</key>

This key contains an array of strings that identify the communications protocols that your app supports.
