TI IOT

The idea is to build a network of sensortags communicating over IPv6 (6LoWPAN).

TI Sensortags (CC2650SDK) will be used a nodes TI CC2538 will be configured as a 802.15.4 sniffer

Creating a 802.15.4 sniffer

1. you need firmware that could act as a sniffer run on that mote (cc2538): the firmware, you could find on example on contiki folder ($CONTIKI_HOME/examples/cc2538dk/sniffer)
2. need software what forward the packet from sniffer to wireshark (available here)
3. setup wireshark to read those packet

To build a firmware, one need to install the proper toolchain first. Instructions are available here

Flashing the CC2538

The goal is to create a new firmware and flash it to the cc2538DK

To create the new firmware, let's use a Contiki example (examples/cc2538dk/cc2538-demo.c)

Instructions are available here https://github.com/contiki-os/contiki/tree/master/platform/cc2538dk

On LinuxMint 17.3, I had to do the following:

• Install gcc-arm-none-eabi and libnewlib-arm-none-eabi (this allows to compile the contiki code)
• if system complains about "Could not find the cc2538-bsl script",

To get uniflash running on a 64bits Unix machine, i had to install the following 32 bits packages:

• libgnomevfs2-0:i386
• liborbit-2-0:i386
• libusb-0.1-4:i386

In Mint: apt-get install libgnomevfs2-0:i386 liborbit-2-0:i386 libusb-0.1-4:i386

Plus, uniflash has to be installed as root, otherwise, we can a connection error

Finally, it is possible to flash using uniflash tool, selecting a binary (.elf) file, specify an address of 0x00200000

SenSniff

SenSniff can be used to get output from the sensortag or CC2538
