• Give Your Camera Real GPS: A No-Internet Hardware Fix with furble

  Wednesday, June 17, 2026Made with AI

  Most cameras still ship without a GPS module, so photos come out of the card with no location data in their EXIF. The official phone apps are supposed to sync coordinates over Bluetooth, but for shoot-as-you-walk travel they fall apart: the BLE link drops when the camera sleeps, it rarely reconnects in time, and the background app gets killed by the OS. This post walks through everything I tried — Garmin GPX backfilling, low-power tracking apps, and my own Koko app built on the reverse-engineered furble protocols — and why none of them fully solved the phone-to-camera flakiness. The real fix turned out to be a tiny piece of hardware: an M5StickS3 plus a GPS unit, flashed with furble, that pairs straight to the camera, needs no internet, and feeds live coordinates into the EXIF. Includes a shopping list with USD/CNY prices and a realistic battery-life estimate for the 250mAh build.
