devzone.nordicsemi.com is the company blog at devzone.nordicsemi.com, writing about hardware and systems. Since 2017, 13 different Hacker News readers have linked it 14 times. It is still writing: the last post was on 2026-11-02, and you can follow it by feed.
Too few sampled comments (11) to say how often HN recommends it.?
Why HN links it
HN commenters link Nordic Semiconductor's developer blog and forum for Bluetooth LE range tests, power budgets, PCB design guidance, DECT NR+ and VS Code tooling, usually as supporting references.
Summarised by Claude from a sample of 11 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
What Hacker News says?
Bluetooth LE which most smartphones support today is quite a bit different from Bluetooth classic. It typically runs at 1 or 2 Mbps and can trade bandwidth for error correction to get some impressive range. For example, this guy got 1.6 miles at 8dbm transmission power. https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/pos... The audio codec on ble is more modern too. > “You can't even hear a ok quality music…

HN discussionAt least one forum uses them to notice followup posts https://devzone.nordicsemi.com . It's redundant in that the forum can be told to notice by email.

HN discussionIt's a milliamp-hour. The processor draws about 220uA [1] so you have about 818 hours (=34 days) of CPU time, but you need to take display current out of that budget too, and an easy source for that probably exists, but I can't find easily.

on “Open Source Smartwatch”Probably hardware-related. Good, or at least thouroughly-tested and characterized, design can make or break high-frequency RF applications. Check out the PCB guidelines for the popular NRF51822 Bluetooth tranceiver: https://devzone.nordicsemi.com/blogs/655/general-pcb-design-... It barely scratches the surface, and in reality there will always be some trial and error as other nearby circuit elements can cause unpred…

on “Ask HN: Why is Bluetooth so unreliable?”> BLE 4.2 adds 'Secure Connections'. This is apparently also broken and what's more it was broken in 2008 when the same pairing method was used in Bluetooth 2.1!! It doesn't totally break pairing - only the passkey entry method - and you only learn the passkey, not the LTK. But it does allow an attacker to perform a MitM attack if the passkey isn't changed for every pairing attempt. https://devzone.nordicsemi.com/f/…

on “Bluetooth Low Energy Swiss-Army Knife”If you think so, you've to state what the power use was of the chipsets you've used. For example the well-known nRF51: https://devzone.nordicsemi.com/f/nordic-q-a/1657/how-to-mini... . It can be as low as 20 uA. Between advertisements 4 uA.

on “A decentralized peer-to-peer messaging application that operates over Bluetooth”Correct! It's relatively straightforward, actually: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/pos... You use one of the /64 tunnels provided for you to route the /48 tunnel to the rest of your network. You advertise a subnet from your /48 to your local network and if you've got SLAAC enabled on your hosts that's all there is to it. You may need to mess with the default DNS server to get IPv6 results,…
