If somebody would like to create an own Bluetooth 4.0 app like a proximity tag, a temperature sensor or a watch she/he can get a one day training and a BT 4.0 / BT Smart evaluation kit for USD 0. I will put the antenna consulting free of charge on top. BTW, I will stay […]

Embedded GSM, Bluetooth and RFID antennas free of charge
Last two weeks I made four times antenna consulting. The antenna is the key in any wireless application. I all four projects is a self made antenna in use. 1. Embedded dual band GSM antenna at link as below One company emailed me. I made my answers public. The other project has already started. I […]
nRF51 Bluetooth Smart – Bluetooth Low Energy – BT 4.0
The nRF51 Series features higher performance, lower power and a new so-called System-on-Chip (SoC) architecture. This architecture supports several protocols: Nordic’s proprietary Gazel ANT Bluetooth Low Energy (BT Smart) It was claimed that the nRF51 will cut the power consumption by as much as half for some applications compared to the current nRF24L Series. The […]
Bluetooth 4.0 will change our remote controls
Have fun by reading the interesting article. If someone is interested in an own Bluetooth 4.0 (Bluetooth Low Energy, Bluetooth Smart) application, then just ask for an evaluation kit by email to harald.naumann (at) gsm-modem.de
Bluetooth Proximity Tag on Kickstarter
If somebody wants a working demo of a Proximity Tag, then just drop an email to harald.naumann (at) gsm-modem.de. The evaluation kit for a Bluetooth Low Energy IC I have in my office. One of my customers is in the key-fob industry and developed a keyfobs with 868 MHz radio inside. Bluetooth Low Energy also […]
Don’t buy antennas – just print it
Antennas can be printed direct on plastic. This saves space and saves money as well. Not even the antenna can be printed; some PCB tracks can be printed as well. The enclosure can be used like a PCB. It can hold LEDs, buttons, connectors or whatever you like. Even a touch panel could be a […]
GSM phone – 15 years on a single charge of an AA battery
Not to bad. Link to the description of the phone. http://www.intomobile.com/2012/05/16/spareone-phone-lasts-15-years-single-aa-battery/ Nevertheless I am working on a 65 gram bird tracker with the target to run endless. Right now Eneloop batteries are in use. Eneloop offers a self-discharge of 25% within 3 years. If the self-discharge is linear, then after 15 years 23,7 % capacity […]
70mm x 40 mm GSM / GPS tracker
The sketch I made during a three day technical training related to GNSS (GPS, Glonass, Beidou, Galileo, QZSS). The PCB can be even smaller, but this will minimise the efficiency of the antennas. The GPS chip antenna would like to have a ground plane of 22,5 mm left and 22,5 mm right. 22,5 mm x […]
WiFi, Bluetooth, GSM? Whatever happened to X10?
The question as below reached me after publishing the Home Automation Solution on the Google TV box on different channels. http://www.gsm-modem.de/M2M/m2m-componets/home-automation-on-google-tv-box/ I would like to share it with you. WiFi, Bluetooth, GSM? Whatever happened to X10? Thanks for the links Harald. They are definitely applicable to M2M! The TV box we got from Google helps […]
