What to know

  • PMSG, an open-source hardware project, published a testable BLE convention broadcasting whether smart glasses are idle, recording, or using a live microphone — before any commercial PMSG glasses ship.
  • NearLens says it will add detection of the PMSG signal to an upcoming iOS release, becoming one of the first consumer apps built to recognize the convention.
  • The protocol is explicitly described as a preference mechanism, not enforcement: compliance depends on manufacturers choosing to honor do-not-record requests and accurately advertise their device's state.
  • The announcement lands amid a broader week of media analysis (Fortune India, Reuters/CNA, trade press) questioning whether smart glasses' recording indicators and privacy safeguards can earn public trust.

    PMSG publishes open BLE recording-state signal; NearLens joins

    PMSG releases an open, standards-oriented Bluetooth Low Energy convention with markers for idle, recording, and live-microphone states plus a bystander do-not-record request, published before PMSG's own glasses reach commercial release. NearLens announces a partnership to implement detection of the signal in an upcoming iOS release, adding real-time recording-state awareness to its existing presence detection.

    “PMSG has turned a difficult public-interest problem into an open convention the industry can test, challenge and improve.”

      One more reason to avoid "smart glasses" products: at least some models have no protection against hacking whatsoever. https://www. abc.net.au/news/2026-09-22/sma rt-glasses-testing-security-flaws-exposing-data/107137552 # privacy # privacymatters # smartglasses # tech # technology # hacking # bluetooth # wearables # ai # security # cybersecurity

    • So do most businesses apparently. Almost every week sees another data breach. It’s laughable at this point to be authenticated by providing name, address, dob and mobile number. Every man and his dog has access to this info now, due to so many breaches.
