The battery level your device reports is read at rest and tracks energy. It browns out under load, when the voltage sags. Here is why your battery percentage can't see the reset coming, shown on the bench, and how to design around it.
Nordic's nRF54L15 Tag is a dual-antenna, coin-cell Channel Sounding prototyping platform. A hands-on look at the board, why the second antenna matters, and ranging against it from a phone.
A hands-on Voice Workout demo on the Nordic nRF54LM20 DK using the Axon NPU and Bluetooth LE. Nordic's bundled wakeword + KWS models do the work.
For ten years I wanted a better embedded log viewer, specifically for Bluetooth LE work. In March 2026 I finally built one, in about six hours, with help from an AI coding agent. Here is what didn't work, what changed, and what shipped.
What Bluetooth LE Audio and Auracast actually are, how they relate, and what the six LE Audio profiles (BAP, PBP, CAP, TMAP, HAP, GMAP) each do.
We tested ABS plastic, ceramic tile, drywall, insulation, and aluminum in a $4,000 RF chamber. How much does each block Bluetooth LE 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 nRF54LS05A and LS05B: entry-level Bluetooth LE SoCs with 128 MHz Cortex-M33, 508 KB NVM, and ultra-low power for sensors, beacons, remotes.
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.
Capture and analyze Bluetooth LE connections with nRF Sniffer and Wireshark. Covers CONNECT_IND, Link Layer procedures, and ATT/GATT operations.
Hands-on first test of a Ramsey STE3000M RF shielded enclosure with a BleuIO Bluetooth LE dongle, with door open vs closed scan results.
I tested a Ramsey STE3000M RF shielded enclosure with a Bluetooth LE dongle. Door open vs. closed scan results show dramatic signal isolation.
