Intel Gemini Lake Block Diagram and Yet More Info

So yesterday, I wrote about some of the new features of Intel Gemini Lake processors like native HDMI 2.0, 4-wide pipeline, 10-bit VP9, and possible built-in 802.11ac wireless controller. I went to bed, and somehow this morning I woke up with something that looks like Gemini Lake (GLK) block diagram, and a few more details. So we indeed have HDMI 2.0 output, as well as DP 1.2a and eDP 1.4, and an embedded wireless controller via the CNVi (Connectivity Integration Architecture) block for WiFi’s MAC and Bluetooth’s MAC + Baseband modem. We’ll have plenty of USB 3.0 host interfaces, and the usual PCIe and SATA 3 interfaces. Still no UFS support, but eMMC 5.1 is supported, as well as x128 DDR4, LPDDR3 and LPDDR4 memory up to 2400 MHz (No ECC support). Cache size is confirmed to be 4MB for up to four GoldMont Plus (GLM+) cores, which combined with […]

Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Comparison for Bluetooth 5 Applications

Bluetooth 5 was formally introduced earlier this year with promises of four times the range, and twice the speed. Several companies offer chips that are compatible with the new standard, and among them Nordic Semi offers Bluetooth 5 ready solutions via nRF52840, nRF52832, nRF52810 Bluetooth SoCs. However, if you thought – like I did – that all three would provide the same Bluetooth 5 support with just some differences in memory, storage and performance, a comparison table put together by Raytac Corporation will show that among the three SoCs only nRF52840 will support the longer range, while the two older SoC only support the extra bandwidth offered by Bluetooth 5. I could find a blog post about a long range demo that confirms the above: Two nRF52840 Preview Development Kits (PDK) or nRF52832 Development Kits. A combination of the two different kits can also be used. Notice that if the […]

Bluetooth Low Energy Now Supports Mesh Networking for the Internet of Things

The Bluetooth Special Interest Group (SIG) has announced support for mesh networking for BLE, which enables many-to-many (m:m) device communications, and is optimized for large scale device networks for building automation, sensor networks, asset tracking solutions, and other IoT solutions where up to thousands of devices need to reliably and securely communicate with one another. The standard actually specifies 32,767 unicast addresses per mesh network, but that number of nodes is not achievable right now. Mesh networking works with Bluetooth Low Energy and is compatible with version 4.0 and higher of the specifications. It requires SDK support for the GAP Broadcaster and Observer roles to both advertise and scan for advertising packets, and the FAQ claims Mesh Networking does not require extra power, and the devices only need to wake up at least once every four days or when they have data to transmit. Mobile apps connecting to mesh networking products […]

Flic Hub Controls WiFi, Bluetooth, and IR Devices with Bluetooth LE Buttons (Crowdfunding)

This week-end, I wrote about 1btn open source WiFi button that can allow you directly control WiFi appliances, and/or set scenes without the need for a smartphone. We also discussed limitations of WiFi due to high power consumption, security issues and the one-way aspect of RF communication, and that Bluetooth 5 may be a better option for range and battery life if possible. Flic Hub is another way to approach the issue, as it combines Bluetooth LE buttons with a gateway supporting WiFi, Bluetooth, and infrared. Flic Hub gateway specifications: Connectivity – Bluetooth Classic, Bluetooth LE, WiFi, Ethernet, IR via optional add-on accessory. Audio – 3.5mm audio out/mic in Power Supply – 5V via micro USB Power Consumption – 1.5W typ. Security – SPARKE2+ Bluetooth encryption Dimensions – 85 x 50 x 15 mm Weight – 99 grams Users can configure workflows by setting up Flic with IFTTT, Zapier, Microsoft […]
