本文章主要介绍是用ZYNQ7020+AD9361+Gnu radio是搭建一个蓝牙抓包器的文章。用SDR(Software Defined Radio）设备研究了下BLE的抓包，通过BLE的抓包了解下蓝牙的controller的一点点内容，日拱一卒，拱了2个周终于可以抓到蓝牙37通道的广播数据，并且可以把数据传送到Wireshark中。

而当学霸君逐渐开始读研读博，在苦逼学术圈当牛做马后，突然在某一天惊恐地意识到：俺们学术圈可能也有自己的「扫地僧」。

这些人会通古今学贯中西，文理兼修农工并蓄，上能紧跟时代前沿命中科研热点，下能洞察论文语病格式 bug。

甚至当你有什么找不到的学术资料时，我们「藏经阁」里一般都能翻出来。

你问他们是谁？是资深教授、杰出青椒，还是实验室里那个从未露面却又声名远扬的传奇学长？No,We.

When the excellent students gradually began to read a doctoral degree, after the helpless pain of academic circles, suddenly realized in a panic one day: our academic circles may also have their own "sweeping monk".

These people will learn both ancient and modern Chinese and Western, arts and sciences and repair agricultural and industrial storage, can keep up with the forefront of The Times hit the scientific research hot spots, and can insight into the format of paper bugs.

Even when you have academic materials that you can't find, we can usually find them in our "cabinet of Sutras".

Who are they, you ask? Is it the senior professor, the brilliant green pepper, or the legendary senior in the lab who has never been seen but has gained fame? No,We.
