+CC1200 README
+========================
+
+The CC1200 sniffer is heavily based on the CC2538 sniffer, used with the
+IEEE 802.15.4 Sensniff application by George Oikonomou.
+
+Sensniff requires [Wireshark](http://www.wireshark.org/).
+
+Get Wireshark
+-----------------
+The best way is to go to the Wireshark site and follow the instructions for your
+specific OS, in a bundle this will install for Ubuntu/LInux systems:
+
+`sudo apt-get install wireshark`
+
+To allow non-super users to capture packets:
+
+`sudo dpkg-reconfigure wireshark`
+
+Flash the sniffer application to the Zoul
+-----------------
+make sniffer.upload
+
+Run Sensniff
+-----------------
+```
+git clone https://github.com/g-oikonomou/sensniff
+cd sensniff/host
+python sensniff.py --non-interactive -d /dev/ttyUSB0 -b 460800
+```
+
+On another terminal run:
+
+`sudo wireshark -i /tmp/sensnifff`
+
