Tutorials, guides, and insights on Bluetooth Low Energy development, from protocol fundamentals to advanced implementation techniques.
Every Bluetooth LE product has to work through walls and enclosures. We measured signal loss through five common materials inside a professional RF shielded chamber — real data at 2.4 GHz.
How much signal do common building materials actually block? We tested five materials inside a $4,000 RF shielded chamber with real Bluetooth LE measurements.
Nordic's nRF54LS05A and nRF54LS05B bring the nRF54L Series' 22nm power efficiency to simple, cost-sensitive Bluetooth LE applications — with aligned pinouts across the nRF54L Series and nRF Connect SDK Bare Metal support.
Learn how to connect your Bluetooth LE devices to Hubble Network's global IoT infrastructure—90M+ smartphone gateways—using Nordic's nRF54L15 and the reference app.
Learn how to capture and analyze Bluetooth LE connections using the nRF Sniffer and Wireshark. Covers CONNECT_IND packets, Link Layer control procedures, ATT/GATT operations, and connection debugging techniques.
The first in a new Academy-exclusive series: hands-on RF testing inside a professional shielded chamber. Episode 0 covers the unboxing, first power-on, and a simple door open vs. closed scan.
I picked up a Ramsey STE3000M RF shielded test enclosure and ran a simple experiment: scanning for Bluetooth LE devices with the door open vs. closed. The results were dramatic.
Learn how to build a proximity-based Mac unlock system using Bluetooth Channel Sounding with a Pixel Watch 4, Silicon Labs xG24 development kit, and Python. Includes working video demo and source code.
A Bluetooth LE sniffer is one of the most crucial tools that every Bluetooth developer should have on hand.
After a decade of teaching Bluetooth LE with SDKs and dev kits, I found a better way for certain learners. Here's why I built Bluetooth LE Unplugged around BleuIO's AT command approach.
If you've ever spent hours wrestling with native Bluetooth LE debugging tools, dealing with complex setup procedures, or waiting for app store approvals just to test a simple characteristic read, you're going to appreciate what I'm about to share with you.
Learn Bluetooth LE the easy way—no SDK, no embedded C, no compilation. Get your BleuIO dongle scanning for devices in under 10 minutes with simple AT commands.
