Using NFC for Bluetooth Pairing

The NFC Forum and the Bluetooth Special Interest Group (SIG) announced the publication of Bluetooth Secure Simple Pairing Using NFC. This new document provides developers with examples of how to implement Bluetooth Secure Simple Pairing (SSP) using NFC to take maximum advantage of both technologies when they are present in the same device. Bluetooth Secure Simple Pairing Using NFC describes the interaction of Bluetooth technology and NFC during SSP in details and provides examples of both negotiated and static handover in the most feasible use cases involving both technologies. Developers will find the examples useful guides for their own work, including: Pairing devices with little or no user interface (such as headsets and pedometers) to smartphones Pairing devices with extensive user interfaces (such as cars) to smartphones Pairing devices such as TVs and smartphones to share photos or to use the phone as a remote control While studying about this […]

List of Wireless Standards for Local and Personal Area Networks

While designing your embedded system, you may have to choose between different wireless standards to match your needs. I’ll provide a list a short and mid-range wireless standards, their description and links to open source software stacks (when available) to help you better understand the different options available. Wide Area Network wireless network such as LTE, Wimax, etc.. won’t be discussed in this blog entry. Mesh and IP Networks: Wifi (IEEE 802.11): Wifi is probably the most used wireless standard in consumer electronics devices today as it allows users to connect their device to their LAN wirelessly. An access point has a typical range of about 20 meters indoors and up to 100m outdoors. There are 4 standards 802.11a 802.11b, 802.11g and 802.11n. The latest has a theoretical throughput of 300 Mbps. Check out Wikipedia Wifi page for details. The Wi-Fi stack is part of the Linux kernel but you […]
