Hackaday Links: April 26, 2020

Gosh, what a shame: it turns out that perhaps 2 billion phones won’t be capable of COVID-19 contact-tracing using the API that Google and Apple are jointly developing. The problem is that the scheme the two tech giants have concocted, which Elliot Williams expertly dissected recently, is based on Bluetooth …read more

Poking Around the Wide World of Bluetooth

Bluetooth is a technology with a very interesting history. When it first came around in the late 1990s, it promised to replace the mess of wires that was tucked behind every desk of the day. Unfortunately, the capabilities of early Bluetooth didn’t live up to the hype, and it never …read more

New Bluetooth 5 Channel Hopping Reverse Engineered for Jamming and Hijacking

Bluetooth Low Energy (BLE) 5 has been around since 2016 with the most recent version 5.2 published just this year. There’s not much hardware out there that’s using the new hotness. That didn’t stop [Damien Cauquil] from picking apart BLE 5’s new frequency hopping techniques and updating his BtleJack tool …read more

Neat Smart(ish) Watch Build Uses BLE

Digital watches are a pretty neat idea, and are a great way to experiment with designing and building low-power circuits. That’s what [Eric Min] did with this neat smart watch build. It’s based around an nRF52832 SoC that does all of the heavy lifting, including connecting to a smartphone to …read more

Which Wireless is Right Wireless?

Back in the early days of Arduino proliferation (and before you ask, yes we realize there was a time before that too), wireless was a strange and foreign beast. IR communication was definitely a thing. And if you had the funds there was this cool technology called ZigBee that was available, often in funny blue house-shaped XBee boards. With even more funds and a stomach for AT commands you could even bolt on a 2G cell radio for unlimited range. WiFi existed too, but connecting it to a hobbyist ecosystem of boards was a little hairier (though maybe not for …read more

Beginning BLE Experiments And Making Everything Better

Successfully connecting things without physical wires has a profound effect on the maker brain. Machines talking to each other without any cables is as amazing today as it was a decade ago. When Bluetooth came out, it was a breakthrough since it offered a wireless way to connect cellphones to a PC. But Bluetooth is a complicated, high-bandwidth power hog, and it didn’t make sense for battery-powered devices with less demanding throughput requirements to pay the energy price. Enter Bluetooth LE (BLE), with power requirements modest enough to enable a multitude of applications including low power sensor nodes and beacons. …read more
