在论坛前辈的帮助下，终于完成了烧录和实现两个板子之间的通信。作为一个入门级菜鸟，我感到非常高兴，也非常感谢，这里真的是个好地方。
但是我自己依然还是对BLE的应用开发没有什么具体的概念，是否是使用BTOOL？我一直在看User‘s guide原来所有的问题都可以在上面找到答案，建议所有的新手都去认认真真的看USER'S GUIDE。
我发这个帖子的目的是问一下当我已经烧入了 SimpleCentral hex文件和peripheral hex文件，并且使用JOYSTICK 测试他们以后，如何实现对他们的应用，谢谢！
BTool is a PC Application that allows a user to form a connection between two BLE devices. BTool works
by communicating with a CC2540/41 acting as a network processor by means of HCI vendor specific
commands. You will be able to perform the same functions very similar to those in the SimpleBLE demo;
however with BTool you will have much broader control of the central device.
User’s guide上面的这段话似乎是介绍了BTOOL对他们的作用，恕小弟才疏学浅，大部分看得懂，但是BTool works by communicating with a CC2540/41 acting as a network processor by means of HCI vendor specific commands 这句话，我不能特别清晰的理解他的意思。
（1）acting as a network processor 是说对他们之间的交流信息进行处理？
（2）通过HCI,应该是人机交互吧，specific commands 是什么意思，HCI是一种语言类似C吗,是一门课程吗，我需要去学吗？如果需要请告知，我立刻去学，我时间多，下学期只有一门CMOS模电设计，谢谢各位前辈。
（3）以我目前的水平是否能够实现对BLE的应用开发，如果不行，怎样才可以？ 以前发过一个帖子，问论坛前辈如何全面了解我手上的板子，所以大致我已经明白，但是现在也是比较急，因为教授甩给我这个板子目前是让我自己去研究，说不定就要让我开发点什么东西出来，所以我才有这个问题，谢谢各位。

小弟背景单一除了大学基础的C语言，高数，和电路分析，别的就没有了。目前在学模电，手上的CC2540 DK是目前在研究的东西，教授也不管，让我自己拿去研究，所以还请帮帮忙，谢谢。
