Does the iPhone sdk support l2cap bluetooth sockets?

Question

Does the iPhone sdk support l2cap bluetooth sockets? Any additional information about SDK classes, etc would be greatly appreciated.

Answer 1

No. There are no direct support for Bluetooth APIs in the SDk, REfer the game kit programming APIs for application development with Bluetooth for peer-to-peer gaming

Other than than you will have to join the Made for iPod/iPhone/iPad program to get access and develop bluetooth connected accessories

Answer 2

Bad news from MFI FAQ (2014):

Q: I want to develop an accessory that communicates with an Apple device using only Bluetooth Low Energy. Do I need to join the MFi Program?

A: No. Accessories which connect to an Apple device using only Bluetooth Low Energy/BTLE/Bluetooth 4.0 or standard Bluetooth profiles supported by iOS are not part of the MFi Program.

I'm developing an app to connect with a L2CAP device on Android, now I'm studying porting on IOS but I found this issue.

For enabling a device to talk by Bluetooth, it must integrate the Apple authentication chip into device and must be able to connect with built-in Apple's Bonjour discovery service.

No L2CAP for any device... Sorry!

The latest CoreBluetooth does expose L2Cap through CBL2CAPChannel: https://developer.apple.com/documentation/corebluetooth/cbl2capchannel

It can be opened from a CBPeripheral: https://developer.apple.com/documentation/corebluetooth/cbperipheral/2880151-openl2capchannel
