Jose - the EA framework is only used for devices that support iAP over Bluetooth, which I suspect your speakers do not. There’s no public interface for other Bluetooth Classic devices.

Hey David, 

Here is a link to my project in case it would be easier for y'all to see it.

Again, thank you very much for taking of your time to help me.

Hey David, 

Thank you very much for getting back to me. 

I am using both BTLE via CoreBluetooth and classic Bluetooth via the External Accessory Framework. 

I have read the whole internet. Hahahaha.  At this point, I just want to get the list of classic bluetooth accessories connected to the phone. 

When I execute this code the connectedAccessories array is always empty. Even when I have classic bluetooth speakers playing music from my phone. 

              NSArray *connectedAccessories = [self.externalAccessoryManager connectedAccessories];

Hey Jose. 

Sounds like you are trying to use core bluetooth to communicate with devices that are not Bluetooth Low Energy or Bluetooth Smart or Bluetooth 4.0 (whatever the marketing term is). 

I'd suggest searching one of those terms and reading up and then you will know what types of devices you can write apps for. 

Cheers

Hello Everyone,

I am very excited to join this mailing list as I just started developing an application to communicate with bluetooth accessories.

As of right now I am stuck in not being able to determine which external accessories are connected to my device. I would sincerely appreciate your help in this matter.

Thank you very much in advance, 

Jose Jose Q. 

P.S. I was attaching the .m and .h files of the class I am using to deal with all bluetooth related tasks. But my message was rejected. Moderator told me to trim it to under 24KB. I had also attached an image with the protocols I added in the info.plist. However, my app always returned an empty array for connected devices even when my phone is connected to my car or playing music in a bluetooth speaker.
