If you are in GPS tracking business and have customers or plans to deliver to Russia, then it makes sense to have a look on a combined GPS/Glonass module.
What to do with Bluetooth Low Energy? Which applications can we cover? Several short articles shall give you an idea for useful applications on BLE. The first article is related to my lost key-fob. BLE beacon at key-fob (1) Estimated twenty-five years ago I lost my keys at the ruins of Corinth in Greece. I […]
iBeacon are radio devives on in 2400 MHz range. They use the new Bluetooth 4.0 specification. BT 4.0 is split in classic Bluetooth and Bluetooth Low Energy. Bluetooth Low Energy was previously called Bluetooth Ultra Low Power, and in early 2001, was WiBree. “Wi” for wireless, and “Bree” for Bree in the Lord of the […]
Question about Bluetooth Low Energy (BLE) in home automation to me: Q: I’m working for an IoT start-up and we are looking at BT 4.0 for communication in home automation. We would really like to know about your opinion about BT 4.0, while we have ZigBee and other protocols for home automation, I feel the […]
