Hardware

SmartRF06 EB (Evaluation Board)

SmartRF06 Evalution Board is used to debug, flash, or it could act as power supply for other micro controllers like CC2538 EM or CC2650 sensortag.

• Power supply (Battery, USB pc or 5V external source, external source(3.6v))

SmartRF06 EB can be powered by several sources:

• • Batteries (two 1.5v batteries) [todo: image]

The image shows a switch for battery power source [todo: image switch]

• • USB (1.5v via PC usb port or external usb source) [todo: image]

USB switch for USB source (1.5v) [todo: image switch]

• • External regulated source (3.6v)

pin used for external source (3.6v) [todo: image of the pin switch] (warning: not tested)

• • Reset Button

When connect to a microcontroller, SmartRF06EB, to some extents, is able to:

• • • Reset(restart) the microcontroller firmware by clicking reset button [todo: image]
    • Boot to bootloader(in case of CC2538) by holding select button while clicking reset button [todo: image]

Note: Have to have bootloader bit enable (link to cc2538 for more detail)

• Connect to other controller
  • CC2538 [todo: image]
  • Sensortag [todo: image]

Note: SmartRF06 has a jumper that allow debugging and flashing on some microcontroller possible. (XDS100v3). [todo: add image , write more detail]

CC2538 EM

CC2538 Evaluation Module (EM) board is used to measure/evaluate RF performance. It operates on 2.4GHz frequency. In addition, CC2538 EM has pre-installed firmware that could be used to test send/receive packet. The hardware is not limited to the factory software, it's possible to flash other firmware to fit other purposes.

• Power supply (throught EB or 3.3v usb)

CC2538 could be powered by:

• • SmartRF06 EB

1. Connect to correct PIN on CC2538 [todo: image] 2. Connect CC2538 EM to SmartRF06 [todo: image] 3. Power the SmartRF06

• • USB port (not yet tested)

1. Connect to correct PIN on CC2538 [todo: image] 2. Connect to external source via usb

Compile Firmware

• Make command

Flash Firmware

• How to reset , go to bootloader (boodloader sequence check)
• CC2538-bsl
• Uniflash (Linux)**
• SmartRF Flash Programmer**
• Restore to Default firmware (Factory Firmware)

//**Note: Could be moved to Tools sections

CC2650 Sensortag

• What it can be used
• Power Supply (Through Sensortag DevPack (note: some usb cable doesn't work), Battery, CC2538)
• Default function of buttons (Disconnect, Reset to factory)

Compile Firmware

• Make command (Could point to contiki project structure section)

ex: make TARGET=srf06-cc26xx BOARD=sensortag/cc2650 cc26xx-web-demo.bin

Flash Firmware

• Flash via OAD
• Flash Default Factory Firmware
• Uniflash (Linux)**
• SmartRF Flash Programmer**

//**Note: Could be moved to Tools sections

CC2531 Dongle

• What it can be used. (Sniffer, Mote, Slip-radio)

Software and Platform

Software (Tools)

Uniflash

• Note: install for all user vs for root only

Sensniff

• cc2538 (project conf) : #define CC2538_RF_CONF_SNIFFER 1

                         #define CC2538_RF_CONF_CHANNEL 26

Components for Designed network

Motes

• What is motes
• What is it consist of and its functions
• What hardware can be used.

Network (WSN)

6lowpan

• Idea/why 6lowpan
• Basic function

Security

• Protocol implementation
• Right/Trusted Motes?
• Probe message attack (make mote wake up all the time)
• Relay Message?
• Exchange data
• What use cases/scenario

Issues faced

Compilation

Sometimes, when the output filetype is not specified (Ex: make TARGET=srf06-cc26xx BOARD=sensortag/cc2650), the compilation returns error with: [todo: image error text]

• Solution:

The problem could be solved by specify the output file. For example make TARGET=srf06-cc26xx BOARD=sensortag/cc2650 udp-client.bin

Pending to be Documented

• flash usb dongle
• access 6lbr embedded webserver from outside
