In keeping with our open source philosophy, all Shimmer’s firmware is freely accessible through various online repositories. With a host of stock firmware available, we have worked hard at ensuring Shimmer users benefit from some of the most efficient and effective wireless sensing firmware available, with low power communications and a flexible, highly configurable nature.
All Shimmer firmware is freely available in public online repositories however, below we have listed some featured firmware for Shimmer users depending on your data capture requirements.
The BTStream firmware provides Shimmer 2 and Shimmer 2r users with full configuration and synchronised data capture capabilities for multiple shimmer devices. The firmware includes additional commands and features for users who are streaming sensor data in realtime using BT.
The SDLog Firmware is a solution for configurable synchronized data capture to the Shimmer microSD card. The firmware allows Shimmer2 and Shimmer 2r users to readily set-up their application specific to capturing data to the microSD card. The configuration parameters are saved on the Shimmer microSD card in a configuration file from which they are read by the Shimmer at initialization.
SDLog Firmware features include:

Shimmer Research provides a quick start environment for the familiarisation and use of the Shimmer platform. The Shimmer BSL (Boot Strap Loader) provides a range of stock firmware for the use of the Shimmer platform and various sensor modules. The BSL program allows for the Shimmer unit to be loaded with the appropriate firmware when docked in the USB Reader.
The TinyOS operating environment is highly recommended for design, implementation, testing and validation of Shimmer embedded software (firmware). TinyOS offers economy due to the extensive cross-platform open-source code library. Reusing applications on Shimmer is a key advantage of the TinyOS environment and significantly accelerates the software development and validation process. Shimmer’s platform code is actively maintained at:
http://tinyos.cvs.sourceforge.net/tinyos/ (tinyos-1.x and tinyos-2.x-contrib)
TinyOS-1.x code can be found in the contrib/handhelds/ directory.
Current functionality includes:
The video below is an example of compiling TinyOS code using the VMware image, and running a full IP stack on Shimmer.
A full-featured IP stack, including both main socket protocols (TCP and UDP), and a telnet server can be used on a Shimmer, running over the 802.15.4 radio.
This is all run in a ShimmerLive 10.04a VMWare image. The only modification to the image before starting was to copy the folder with the python examples to the desktop. Other than that, it is as supplied.
