Today the bunny will jump out of the heat. Next week at the embedded world you have a chance to win a Gold, Silver, Bronze and Student kit. The Student kit has a higher value than the Bronze kit. Students are our future. All kits together have a value of mare than Euro 10000. The […]
The idea for the NB-IoT shield with Arduino header was conceived in summer 2016. We then produced the first version of the NB-IoT shield at the M2M Summit in September 2016. The second generation was shown to readers of my IoT/M2M Cookbook in our end of the year mailing and it has proved extremely popular; we […]
We have extensively tested the HARduino board over the past few days. We have been testing the GSM version due to the lack of NB-IoT coverage in the region of our office in the North of Germany but both NB-IoT and GSM exhibit the same characteristics in the tests we carried out. The AT command set […]
Many IoT / M2M Cookbook customers asked me for an evaluation kit within the last two years. I launched the first version during M2M Summit in September 2016. In February 2017 the multicellular version came true. The working name is HARduino because it has an Arduino R3 compatible UART interface. HARALD – ALD + duino […]
RF engineers already know that signal propagation characteristics vary according to frequency. In simple terms, signals carried at lower frequencies travel further. Since wavelength equals the speed of light divided by the period of the carrier signal, we can see that low frequency signals have a long wavelength. Long wavelength, low frequency radio waves are […]
Pigeons don’t tweet, they make cooing noises. They don’t wear backpacks either. Usually. Well, say hello to the new breed of backpack wearing, tweeting pigeons that might just save lives. If you live in a city there’s a good chance you’ll be sharing it most days with a large number of pigeons. And generally […]
The IoT-University was launched just one month ago. In just four weeks there are more than 400 students on the course. Students want to learn and to educate them we need more mentors who love to share; we have space for eight more to join us. If you have something to share, join us. Become […]

If you are interested in your own Weightless P BTS and some Weightless P modules then do not hesitate to drop an email to harald.naumann (at) gsm-modem.de . I will take care that you get your […]
At the end of this week Germany, like a lot of other places in the western world, will slow down. It is Christmas time and we start to celebrate on the 24th of December. Before I start to enjoy this time with family and friends I would like to say thank you for all the […]
Bluetooth Low Energy to cellular gateway/hub – concept 1 BLE to cellular gateway The concept is based on a Smart Module. Smart modules offer all in one. The radio part and the SOM are inside the same module. The two antennas will have a bill of material of USD 0 because both could be PCB […]
