I need help on how to use Core Bluetooth to communicate with a PIN-PAD. I’d like to know if that’s possible, and if it is, how can I do it?

Thank you!

  • What is the purpose? There are other communication methods [Multipeer Connectivity"](https://developer.apple.com/library/ios/documentation/MultipeerConnectivity/Reference/MultipeerConnectivityFramework/ "Multipeer Connectivity")

  • Hello! The purpose is to carry out transactions with credit card readers via bluetooth right, but as I’m starting in the iOS environment I don’t have much knowledge yet for the same. At first the idea is to perform a "link" with my device so that I can send and receive information with it. I will test this class Elias. Thank you very much for now!

I understand, this framework it makes communication between devices via (Wifi, Bluetooth) sends data and receives data but would have to check what kind of communication and how to receive and send. Mcdemo an example if you want to run it and make the communication, is a simple example of CHAT, but that uses the framework and its methods.
