Wi-Fi module – five minute set up

This Wi-Fi module arrived yesterday.  The complete package includes the Wi-Fi module,  a USB connector and a Serial Peripheral Interface (SPI) to USB converter. The operating voltage is supplied via USB from the PC. After plugging the module into the USB port, a standard terminal software application was started on the PC. With the first […]

WIFI for creating the IoT?

In the video they mention public #WIFI e.g. at airports. At Mobile World Congress #MWC 2013 WIFI had its one zone. If WIFI will rise in public locations like airports and railway stations it will rise in industrial applications as well. WIFI in IoT – practical paradigm I already guideline the development of applications where […]

Seven at on one stroke – WIFI 2.4, WIFI 5.8, Classic Bluetooth, Bluetooth Low Energy, ZigBee, MCU and periphery

A fairy tale comes true. Seven at one stroke. Besides WIFI 2.4 GHz and 5.8 GHz WIFI also ZigBee, Bluetooth Low Energy and Classic Bluetooth is integrated. In addition, the controller in the module can be used for an individual application. As interfaces for peripherals are I2C, I2S, SPI, QSPI, UART, GPIO, JTAG and analogue […]

Comparison of NFC, Classic Bluetooth, Bluetooth Smart and WLAN

Presentation at Droidcon 2012 in Berlin 16 slides about short range radio links inside an Android device for download: http://www.box.com/s/d538e0081ff656c3d899 The focus of this presentation is on Bluetooth Smart. Bluetooth Smart was called WiBree years ago. Later on it was renamed to Bluetooth Low Energy also called Bluetooth 4.0. Four names for the same technology. […]

To explain the latest technologies we will […]

Google Maps Indoor and Google Maps Floor Plan Generator

Recently you can navigate with the new version Google Maps 6.0 in the building. Various airports and shopping centres in the U.S. have already been equipped. To navigate without GNSS signals (no GPS and Glonass) you need some radio beacons along the way. A mixture of natural radio beacons, such as GSM base stations and […]

M2M module: Embedded Linux, ARM9, GPRS module, USB and further Interfaces

Today I would like to show and to talk about a new Linux based application for wireless M2M. The PCB is already in use in several projects. Based on its enclosure it can be used as a final product for end users. It supports a lot of interfaces like SD card / MMC card, GPIO Pins , AD / DA converter, UARTs, USB Device, USB Host, I2C, SPI and JTAG. At GPIO you will find PMW (Pulse Wide Modulation), counters and other intelligent channels.
