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.
Learn how to implement Bluetooth LE shorter connection intervals for lower latency using the Nordic nRF54L15, with step-by-step configuration and testing.
Learn how to write effective Wireshark display filters for Bluetooth LE packet analysis, from basic protocol filters to advanced expressions for debugging.
Learn how to set up and use the nRF Sniffer for Bluetooth LE with Wireshark to capture and analyze over-the-air packets between devices.
How to use nRF Cloud powered by Memfault for production-ready device management, OTA updates, crash analytics, and fleet monitoring for Bluetooth LE devices.
The Nordic nRF54LM20A builds on the nRF54L Series with 2MB flash, 512KB RAM, 66 GPIO pins, high-speed USB, and a RISC-V coprocessor — all while maintaining Bluetooth LE Core v6.0 with Channel Sounding, Matter, Thread, and Zigbee support.
