Programming language Python Comparing Python with C++ Python code is typically 3-5 times shorter than equivalent Java code. However it is often 5-10 times shorter than equivalent C++ code. One Python programmer can finish in two months what two C++ programmers can’t complete in a year. Python shines as a glue language, used to combine […]

PIC32MX795F512L is the high end of Microchip with most features, Flash RAM and ROM PIC32MX795F512L comes with 80 MIPS, 2 CAN, 1 LIN, 6 UARTS … (more at table as below) PIC32MX795F512L is a 32-Bit uC and available […]
Do you recommend requesting delivery receipt of SMS for M2M applications?
Yes and no. It really depends on the application. A delivery of a SMS is 6 -10 seconds, up to hours and maybe never. In case of emergency SMS can be a risk. Worst case the GSM network is busy. A good example are public events like soccer games or outdoor music festivals in urban […]
What will be the power consumption of the GSM GPS Glonass tracker?
The power consumption is from nearly 1 uA to 480 mA in average. The 1 uA we get if we create an asset tracker behind oil on canvas. The asset tracker will wait for an event all the time. The 480 mA we get by GPRS class 10 in GSM power level with TX output […]
6LoWPAN, Bluetooth LE, ANT+, GPRS, WIFI, DSL, IP ?
Router, nodes, … this came in today “Harald, the term “router” you are using, would also mean WiFi Access Point , would it not? and the topology here would be a star network, correct? with “router” as a star in this architecture. there is no interconnection between “nodes” , correct” Right now I am talking […]
6LoWPAN question: A Low power, what is it good for? Just a waste of time. Everything was already set.
This question came in this morning by comment to a previous post. We’ve been talking of the Internet-of-Things for years, but we forgot to inform our engineers how it will work. The website of the engineer who commented is showing medical applications. I am able to connect all their equipment to my WIFI network easily. […]

Features of Googles Radio protocol 868 / 915 MHz instead of 2400 MHz Frequency hopping instead of Direct Sequence Spread Spectrum like 802.15.4 Licence free 6LoWPAN instead of ZigBee Open source instead of proprietary Advantage of Google´s Radio protocol Better coverage in buildings End-to-end security if they use IPsec Proven standard IPv6 plus 6LoWPAN No […]
6LoWPAN for dummies
6Lo… what? This is the first reaction that you get, if you use the word 6LoWPAN. The word is not easy to speak and spell. Marketing wise is a nightmare. Anyhow, Google will use it. If Google will use the word often enough, then the people will start to remember it. 6LoWPAN meaning IPv6 over […]
