1.2 Introduction

This guide describes the hardware in the box and some of the tools that can be used for developing software at a later stage. For the CC2541DK-MINI, there are two ways of getting started:

1. Evaluate using BTool: BTool is a Windows® application that allows the user to control a central device using the serial interface, and perform various BLE functions while connected to a peripheral device, such as the CC2541 Keyfob.
2. Evaluate using an iOS™ device: Some Apple iOS devices support BT4.0, and Texas Instruments has created an iOS application to evaluate a peripheral device, such as the CC2541 Keyfob. The iOS application runs on:
   • iPhone 4s / 5 / 5s / 5c / 6 / 6Plus / 6s
   • iPad 3 / 4 / air / air 2
   • iPod Touch (5. gen)
