Bluetooth Communication For Remote Controlling Purpose / Bluetooth-kommunikation för fjärrstyrningsändamålFlorén, Johan, Lindberg, Daniel January 2004 (has links)
<p>The concept of remote controlling electrical devices is not new; people of today are used to being able to control their household electronic items without making an effort to walk up to the device. </p><p>In this thesis the aim is to use Bluetooth radio signals instead of the traditional infrared light to achieve the remote control functions. As a test application a Sony Compact Disc player is modified in order to be radio controlled with a standard Ericsson T39 mobile phone used as a remote. Since the test application is rather simple without any special requirements the development of a specific radio communication system has not been considered. Instead available pre-manufactured devices were examined. A Bluetooth evaluation kit was purchased and the test project consisted of the goal of linking the evaluation board to the CD player with an AVR microcontroller and getting the whole system to communicate with the mobile phone.</p>

Univerzální zavaděč pro mikrokontrolér Kinetis K60 / Universal Bootloader for Kinetis K60 MicrocontrollerKrůpa, Tomáš January 2016 (has links)
The scope of this work was to design a bootloader for Kinetis K60, an ARM Cortex-M4 microcontroller. The bootloader should simplify the process of loading user applications to the flash memory of the microcontroller on the Minerva development kit. Based on a quick research of existing bootloader solutions, new bootloader was designed together with communication protocol that would suit the needs for transfer of both the file data and configuration information through all the supported communication interfaces - USB, SDHC, Ethernet and RS-232. On the PC side, development of bootloader’s application library and two supporting utilities with graphical and command line interfaces was made. The system can be used out of the box as well as it can be further extended in the future.

Sanitization of embedded network devices : Investigation of vendor’s factory reset procedureLarsson, Magnus January 2015 (has links)
Embedded devices such as routers, switches, and firewalls commonly have sensitive information stored on them such as passwords, cryptographic keys, and information about the network around them and services that these device(s) provide. When disposing of or reselling this equipment in the secondary market it is crucial to erase this sensitive information. However, there is an important question that must be asked: Do the erase commands and routines offered by the device manufacturers actually erase the sensitive data? This thesis investigates methods and tools to determine the completeness of this erasure in some common network devices. These methods are used on a sample of networking equipment found to still contain sensitive information after being erased according to vendor recommendations. A computer program was developed to show how this information can be removed. The information in this document is useful for equipment owners, brokers and others looking to remarket their current equipment; all of whom want to minimize the risk of leaking sensitive data to other parties. / Nätverksutrustning såsom routrar, switchar och brandväggar har ofta känslig information lagrad internt, som lösenord, kryptografiska nycklar, information om nätverket runt dem samt tjänster de tillhandahåller. Om denna utrustning ska säljas på andrahandsmarkanden eller på annat sätt byta ägare är det viktigt att all känslig information raderas. Men kan man lita på att raderings rutiner och metoder som tillhandahålls av tillverkaren verkligen raderar känslig data? Denna avhandling undersöker lämpliga verktyg och metoder för att granska vilken information som minnen i inbyggda system innehåller. Dessa metoder testas praktiskt på några system som visar sig ha kvar känslig information efter att de raderats enligt tillverkarens rekommendationer. Ett datorprogram som demonstrerar hur denna information kan undersökas och raderas finns med som en del av avhandlingen. Informationen i detta dokument är användbar för ägare av datakomutrustning, mäklare av sådana samt andra som vill minimera risken för att läcka känslig information vid återförsäljning av sin begagnade utrustning.
