Arduino GSM GPRS and GPS shield. Shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version (old Arduino GSM shield) has several new hardware features, that allow maximum customization and provide many configurations. We begin with the supply circuit a simple LM7805. To work, it is necessary to provide an input voltage between 7.5V and 12V. As shown in the circuit diagram, the input voltage, after being stabilized at 5 V, is reduced to 4.3 V by using a diode and provide power to modules that need a voltage between the 3.2 and 4.8 V. An important technical feature is the serial adapter for the communication between the GSM module and Arduino. The news that is immediately evident is the presence of two jacks for audio.

To preserve compatibility with the Arduino Mega, we changed the selection method for the serial communication. [CODE] R1: 10 kohm R2: 10 kohm R3: 10 kohm R4: 10 kohm P1: Microswitch SIM900.h SMS.h. Huawei AT-commands - 3G modem wiki. Note: Some devices like the Huawei K3715 seem to require AT-commands to be typed in capital letters! There are a couple of options for disabling and re-enabling the following USB-components of Huawei USB-modems: modem (M) NAND-flashmemory drive (CD) microSD-drive (SD) PC UI interface (UI) network adaptor (N) smartcard (SC) To disable or re-enable those components run the following AT-command, where n is one of the numbers from the table below: AT^U2DIAG=n On some models it is possible to read the present value of the parameter n by sending command:AT^U2DIAG?

*) note: Smartcard (SC) and network adaptor (N) are not present in many Huawei devices. Modems supporting AT^U2DIAG? Also on some models it is possible to display a list of devices present in a USB-stick, by sending a command:AT^GETPORTMODE. Station DE Travail A AIR Chaud Pour Soudage Dessoudage SMT CMS.

Downloads. Industry leaders cooperate on M2M open source tools, protocols. Vancouver-based Sierra Wireless and the Eclipse Foundation have formed an industry working group to define and implement an open standard platform for the software development tools used in developing machine-to-machine (M2M) communications applications. IBM and Eurotech are also founding members of the M2M Industry Working Group, which is open to any organization with an interest in M2M solutions, including both vendors and potential clients.

"M2M communications represents an exciting and challenging opportunity to positively impact the way our world operates in fields as varied as energy management, transportation, and healthcare," says Mike Milinkovich, executive director of Eclipse Foundation. "We believe the formation of this group comes at a critical time. The open source contributions of M2M tools and protocols will help to reduce development time and costs and ensure that mission critical systems maintain interoperability as deployments evolve over the lifetime of a project.

" m2mblog » Open Source or Standards for M2M Services? The comments received on my last blog – New Standards for M2M Services – have raised some interesting points. I would like to respond to these by introducing what may be an alternative approach to standards-setting for the M2M Services Layer. The goal of standards for M2M is to maximise interoperability.

There is no doubt that standards are required for device interfaces to ensure that different M2M solutions can understand the data being delivered by the remote devices. Standardization at that level means that devices can be made in the millions and be linked to a wide range of applications and services. Does interoperability for M2M services mean there has to be a standard M2M Services Layer though? A proper Open Source environment has rules about who can add new code, when this can be done and who needs to approve it. Fragmented market: wide range of embedded platforms, programming models, connection types, communication protocols.No widely accepted M2M architectural guidelines. OpenSCADA | We are the good guys.

DeviceHive - M2M, Machine-to-Machine Communication Framework. Introduction aux réseaux Z-Wave. Dans un réseau ZWave on peut distinguer 3 types de devices : Les Contrôleurs (Box Z-wave, Stick USB, télécommande etc…) Les Devices qui font un report (Capteurs détecteurs, contact, etc…) Les Devices qui sont contrôlés (Actionneurs, Lampes, Dimmer, etc…) Il n’y a qu’un seul contrôleur primaire par réseau, c’est lui qui va géré la partie ‘inclusion’ des autres composants dans le réseau. Par contre on peut ajouter des contrôleurs secondaires. c'est le cas par exemple des télécommandes. Les Devices de type contrôleur ont un ‘Home ID’ défini en usine et unique. Lors de l’inclusion d’un autre device le contrôleur primaire va donner son home ID aux autres composants pour signaler qu’il font maintenant partis du même réseau.

(Le home Id est défini sur 4 octets (32 bits) Lors de l’inclusion le Node ID est aussi défini (j’ai pas encore bien compris le mécanisme pour le moment) en tous cas c’est un paramètre défini sur 1 octet (8 bits).

Originally appearing in JAX Magazine, Benjamin Cabé introduces Koneki - the new Eclipse venture into M2M technology included in the Juno Release Train. Note this article was written based upon the Koneki 0.8.0 release and before the Mihini project started One of the biggest challenges companies are faced with when building M2M solutions is that they have to deal with a lot of engineering problems, from embedded development to web development – including industrial protocols like manipulation – and there are many different tools to address these different tasks. Koneki aims to provide a set of tools that put them all in a single place.

Just a year after its creation, the Koneki project is part of the Eclipse Juno simultaneous release. Koneki you say? Koneki is a word from the Māori language that means “this place”. Introduction to Machine-to-Machine You may be familiar with the term Internet of Things (IoT). By 2020, there will be around 50 billion connected physical world devices. Django. DeviceHive: An open source M2M development platform. Will Kelly looks at DeviceHive, an open source M2M platform that offers the building blocks for companies to build their own M2M solutions.

Machine-to-machine (M2M) communications frameworks are also known as the Internet of Things. The technology is seeping into applications like fleet tracking, logistics, connected home systems, remote sensors, clean tech, and retail Point of Sale (POS) systems. However, M2M is held back because current M2M development tools and processes aren't very replicable. DataArt, a boutique software development and outsourcing firm based in New York City, recently launched DeviceHive, an open source M2M communications framework from which developers can build M2M projects. Cloud Mobile Embedded DeviceHive is designed to sit in the middle of a network of connected devices and serve as a communications framework for business and consumer applications. The DeviceHive framework includes: A communications layer Control software Multi-platform libraries More resources.
