2.System overview
2.1. SmartMesh IP™ Technology overview
Image 1 Mesh network
A SmartMesh IP™ network consists of a highly scalable self-forming multi-hop
mesh of wireless nodes, known as motes, and an Access Point mote that
connects the motes to the Network Manager, monitoring and managing network
performance and security, and acting as a bridge between the host application
and the wireless network. Motes are capable of two way communication and they
collect and relay data.
2.2. Dusty in a SmartMesh IP™ network
With SmartMesh IP™ time-synchronized networks, all motes in the network may
route, source or terminate data, while providing many years of battery powered
operation. SmartMesh IP™ is a highly flexible network with proven reliability and
low power performance in an easy-to-integrate platform.
The Dusty’s behavior in a SmartMesh IP™ network is determined by the choice
of SmartMesh IP™ network software loaded: Wireless Mote, Embedded Manager,
or Access Point Mote.
The SmartMesh IP™ software provided with the Dusty is fully tested and
validated, and is readily configured via a software Application Programming
Interface.

4.Usage
This chapter describes how to connect, configure and interact with the Dusty
module.
4.1. Power supply
Dusty is powered from a single pin, VSUPPLY, which powers the I/O cells and is
also used to generate internal supplies. Eterna®’s two on-chip DC/DC converters
minimize energy consumption while the device is awake. To conserve power the
DC/DC converters are disabled when the device is in low-power state. Integrated
power supply conditioning, including the two integrated DC/DC converters and
three integrated low-dropout regulators, provides excellent rejection of supply
noise. Eterna®’s operating supply voltage range is high enough to support direct
connection to lithium-thionyl chloride (Li-SOCl2) sources and wide enough to
support battery operation over a broad temperature range.

5.1. Dusty PCB-Ant mounting suggestion
The Dusty PCB-Ant provides an integrated PCB Antenna, therefore it is really
important that the module is mounted on the hosting board in the proper way.
No other components should be mounted around the antenna.
The following picture provides an example of how the module should be mounted
on a hosting board.
Note how the antenna juts out of the hosting board.

6.Firmware Upload
Dusty’s behavior in a SmartMesh IP™ network is determined by the choice of
SmartMesh IP™ network Firmware loaded:
•Wireless Mote
•Emanager
•Access Point Mote.
By default Dusty will have the Wireless Mote firmware preloaded with some
predefined characteristics.
If the user wants to change the firmware or change some parameters it is
necessary to upload the firmware. The firmware can be downloaded from:
https://www.linear.com/mylinear/login.php
In order to download the firmware, the customer must sign in and ask the local
sales team the firmware. They’ll post the file to be downloaded from the Mylinear
web site and uploaded to Dusty.
The firmware upload requires the following tools:
Firmware to be uploaded
 Eterna® DC9010 Serial Programmer
Dusty connector used to connect the module to the Eterna® Serial
Programmer
PC running Windows and USB 2.0 or USB 3.02 port
ESP software (downloadable from
http://www.linear.com/dust_programmer)
Image 7 Required tools to upload firmware

For the detailed procedure and more detailed information see the following
document:http://www.linear.com/docs/en/software-and-
simulation/Eterna_Serial_Programmer_Guide.pdf
7.Software Development
The ARM Cortex-M3 32-bit microprocessor, inside the LTC®5800-IPM SoC,
normally runs the provided SmartMesh IP™ network software, but it can be
customized and allows the user to develop their own software and add
functionality to the module.
The On-Chip Software Development Kit (OCSDK) allows you to write applications
directly on the LTC5800-IP SoC on top of the SmartMesh IP™ network protocol
stack.
The SmartMesh IP™ stack and the device drivers are provided as pre-compiled
libraries. Your mote application links against them, and can then be loaded into
the Dusty board.
In order to develop a custom firmware to be uploaded to the Dusty module, the
following tools are necessary:
•A Windows PC
•IAR Embedded Workbench for ARM. Note that the kickstart addition
will not work with the OCSDK
•On-Chip Software Development Kit (OCSDK) downloadable from
Github (https://github.com/dustcloud/onchipsdk)
•Library files from Linear to be copied into the OCSDK
•Python installed on the PC
•Programming and debugging tools (optional)
All the details and instructions about the development of custom firmware for
the LTC5800-IPM SoC embedded in the Dusty module may be found at the
following link: https://dustcloud.atlassian.net/wiki/display/OCSDK/
