Why HN links it

HN readers link Colin O'Flynn's hardware security posts, including his AirTag teardown and range test and his ZigBee worm write-up. The comments cite them as sources and do not comment on the writing itself.

Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?

  1. You might realize this, but just for clarity, Bluetooth LE has similar range to Classic Bluetooth, with the exception of 125kbps LE long range coded PHY, introduced with BT5.0. You can potentially reach from 1km away outdoors. The Nordic Semiconductor NRF52832 used in the airtag, unlike NRF52840, does not support this. https://colinoflynn.com/2021/05/apple-airtag-teardown-test-p... https://www.nordicsemi.com/Product…

  7. Also consider the hubs. To take a well known example, Phillips Hue lightbulbs don't connect to the net directly and don't have any significant computational resources to speak of. They are just an 8-bit Atmel microprocessor with a Zigbee radio to talk to the hub ( https://blog.adafruit.com/2016/06/14/teardown-of-a-philips-h... ). On the other hand, the Hue hub is running a full embedded Linux distro (which has even…
