Change Log Firmware

v2.8.0​

New Features​

  • Personalised battery gauge: the JedEye can now learn your own battery pack and use it for the battery percentage. A one-time discharge test (batterylog start, run over USB) records the pack's voltage-vs-charge curve into the device — follow the on-screen "disconnect the USB cable" prompt, then leave it running down on battery until it switches off; the curve is in use after the next start-up. Without the test the device uses a good built-in curve, so the gauge works either way. The low-battery warning now appears at about 10% and the automatic power-off at about 5% (both follow the displayed percentage, with a safe voltage floor underneath). You can view the curve with batterylog dump and plot it with the bundled battery_table_plot.py script. See Battery.

v2.7.0​

New Features​

  • Per-unit battery calibration: the battery voltage reading can now be calibrated against a multimeter so it is accurate on every device. Connect over USB, measure your pack, and run calibratebattery 8.23 (whatever your meter reads); the value is saved per device and survives a settings reset. See Battery.
  • Low-battery auto power-off control: the automatic shutdown that protects an in-progress survey can now be switched on or off from the web Settings page or the CLI (setlowbatteryshutdown), and a ~20-second grace window after start-up keeps a mis-reading unit from shutting itself down before you can fix it.

v2.6.2​

Improvements​

  • Over-the-air updates now work on battery: previously an OTA update could only install safely while on USB power — on battery the JedEye could switch itself off part-way through writing the new firmware. The device now holds itself powered through the whole install, so wireless updates finish cleanly on battery. One-time step: because the part responsible can only be replaced over USB, you must install v2.6.2 once over USB to switch this on; after that every future update can be done over WiFi on battery. Brand-new JedEyes already include it. See Firmware Update.

v2.6.1​

New Features​

  • "What's New" screen: after a firmware update (over WiFi or USB), the JedEye now shows a short list of the new version's highlights on the first start-up, so you can see what changed at a glance. It appears once per update, and you can read it again any time from OPTIONS > SETTINGS > SYSTEM > System Info.

v2.6.0​

New Features​

  • Over-the-air firmware updates: the JedEye can now update its own firmware over WiFi — no cable, no copying files. A new OTA UPDATE entry under OPTIONS > SETTINGS > SYSTEM connects to your WiFi (turning it on for you if needed), checks for a newer published version, and — with one Confirm — downloads and installs it, showing a progress screen and rebooting into the new firmware. It updates both the JedEye software and, when a newer one is available, the radio module's firmware in the same step. Even easier: whenever you switch WiFi on, if a newer firmware is available the JedEye offers to install it right there. The classic USB drag-and-drop update (SYSTEM > UPDATE) still works as a fallback. See System and Firmware Update.

v2.5.0​

New Features​

  • Web remote control: the built-in web page can now act as a remote for the device. A new Remote control button on the landing page opens a live copy of the JedEye's screen together with on-screen SELECT and NEXT buttons (laid out like the physical ones). Tapping them drives the menus exactly as the real buttons would, and the screen mirror updates so you can follow along — handy when the device is mounted out of reach. It works on the JedEye's own access point and on your local network, with no internet access needed. See Wireless Data Transfer.

Improvements​

  • Snappier web interface: the web server's request handling was retuned so pages stay quick to load while the remote control keeps up, without the page-loading issues that a simple speed-up caused in the past.

v2.4.3​

Improvements​

  • Automatic radio firmware update: the JedEye now keeps the radio module's firmware up to date by itself. On the first start-up after a JedEye firmware upgrade, if the radio module needs a newer firmware the device flashes it automatically — showing the same progress screen as before — and reboots. You no longer have to remember to run OPTIONS > SETTINGS > SYSTEM > RADIO FW UPDATE by hand after upgrading. If the automatic update can't complete, the JedEye shows a brief notice and starts normally so you can still use it and retry, and the manual menu entry remains available. The automatic check only runs once per upgrade (not on every start-up) and is skipped when waking from sleep. See Updating the NINA firmware.

v2.4.2​

New Features​

  • Scan-to-connect QR codes: turning on the WiFi access point now shows QR codes on the screen so you no longer have to type the network name, password or IP address. Scan the first QR to join the JedEye network; once your phone connects the screen switches to a second QR (and prints http://192.168.4.1 below it) that opens the web interface. The QR clears automatically once the page loads. See Wireless Data Transfer.
  • Automatic web-page open (captive portal): on most phones the JedEye web page now opens by itself the moment you join the access point — the same "Sign in to network" prompt you get on public WiFi. Newer Android phones that only check connectivity over HTTPS won't trigger this automatically; on those, the open-page QR (or typing the address) always works. This required a small update to the radio module firmware, so this release includes a one-time radio firmware update — see Improvements below.
  • QR code on your local WiFi too: when the JedEye connects to your own local network (Station Mode) it now shows a QR code with its web address, so you can scan to open the page from any device on the same network without looking up the IP. See Wireless Data Transfer.

Improvements​

  • Updated radio firmware: v2.4.2 ships a patched radio module firmware so the access point hands connecting devices a DNS server (needed for the automatic page-open above). After flashing v2.4.2, run OPTIONS > SETTINGS > SYSTEM > RADIO FW UPDATE once to update the radio module. See Updating the NINA firmware.

Bug Fixes​

  • Web requests from some clients were dropped: requests from clients that close their connection immediately after sending (common with phone connectivity checks) could be ignored by the web server. The server now reads the full request in these cases.

v2.4.1​

New Features​

  • 3D Web View: the embedded webserver now offers an interactive 3D view of each survey, reached from a new 3D button on the 2D View page. The view renders the survey path with depth colouring (blue = deepest, red = highest), the full per-shot lidar point cloud, an auto-scaling ground grid (centimetres or metres depending on the survey extent), and a compass-rose E/N/U axes widget. Left-drag rotates, right-drag dollies the camera, scroll wheel or pinch zooms, and clicking a station re-centres the orbit. Like the rest of the JedEye web interface, it works over Access Point mode with no internet access — there are no external dependencies. See Wireless Data Transfer.
  • Lidar outline on 2D map: the existing 2D survey view now also draws the per-shot lidar outline (previously the data was collected but not rendered on the web view).

Improvements​

  • Redesigned web interface: a new dark theme with self-hosted fonts (Inter and JetBrains Mono) bundled into the firmware — no Google Fonts or external CDN, so the UI renders correctly in Access Point mode where there is no internet route. The landing page has a clearer header with the device name and serial, an action grid for the download options, and a two-line survey list. The JedEye Settings page has a card layout, segmented controls for date format / stabilization preset / sensitivity preset, and a cleaner WiFi network list with a green-dot SSID prefix.
  • New favicon: the browser tab now shows the JedEye logo instead of the previous MNemo icon.
  • Settings page copy refined: the descriptions for stabilization, slider button, confirm-measure, switch-on safety and auto-sleep have been rewritten to make their actual effect clearer.
  • Web UI accessibility: the active option in each segmented control is now correctly announced as the current selection by screen readers, and is no longer (incorrectly) focusable as a link.

Bug Fixes​

  • Volumetric data dropped on save (v2.4.0 regression): on v2.4.0 the per-shot lidar volume could appear to save successfully on the device — progress bar to 100 %, no error reported — but the bytes would not actually land on the radio module's flash, so the volume block was missing from the data dump. The race that caused this was hidden when the device was tethered to USB, so the failure most often appeared on the field. v2.4.1 holds the CPU across the chunked transfer to the radio and the volume is now reliably written. If you ran v2.4.0 in the field, upgrade to v2.4.1 before relying on the lidar point cloud in any of those surveys.
  • 2D web map mirrored vertically: the 2D survey view sent by the webserver was flipped on the Y axis (north pointing down). Fixed.
  • Stylesheet silently truncated: the page stylesheet was being cut off at the radio's transmit buffer, so most of the page rendered with default browser styling. The CSS is now streamed in small chunks like the favicon and the other static assets, with a cache header so a return visit doesn't re-fetch it.
  • Long survey list truncation: the survey list on the landing page could truncate a row's markup once the meta sub-line was added. The internal buffer has been enlarged.
  • Sensitivity preset chips (Low / Mid / High / Ultra-High) on the Settings page were returning Not Found instead of changing the threshold. Fixed.
  • HTML escaping: the device name and serial are now HTML-escaped in the page header, so a special character in a custom device name (set via the CLI setname command) can no longer break the page.
  • EEPROM write reduction: opening the Settings page no longer rewrites the entire settings block to EEPROM. The settings are now written only when a setting actually changes, preserving EEPROM lifetime over long use.
  • HTTP routing: routes can no longer shadow each other as prefixes. Out-of-range id parameters on the survey views now return a 400 instead of reading past the end of the survey list.

v2.4.0​

New Features​

  • In-device radio firmware update: the JedEye now carries its own copy of the radio module firmware (nina-fw) and can reflash the module itself. No PC, no Arduino IDE, no arduino-fwuploader. The new flow lives at OPTIONS > SETTINGS > SYSTEM > RADIO FW UPDATE and is gated by a Confirm / Back submenu so it cannot fire on a stray click. While the flash runs, the screen shows the current and target radio firmware versions and a progress percentage; when it succeeds the JedEye automatically reboots into the new firmware. See Updating the NINA firmware.

Improvements​

  • Menu reorganisation: Radio FW Update moved from OPTIONS > TOOLS to OPTIONS > SETTINGS > SYSTEM, alongside the other firmware-management entries (Update, Reset Settings, Reset Memory). The old Tools location now carries a pointer to the new spot.
  • Automatic passthrough fallback: builds that do not embed the radio firmware blob (offline builds, explicit opt-out) still expose Radio FW Update. Picking Confirm drops into the v2.3 USB-to-radio passthrough mode automatically so a PC tool can complete the update.
  • Robustness during a flash: the in-device flasher disables button input, button-repeat handling and the serial CLI for the duration of the operation, and uses framework-level yield primitives rather than the cooperative task scheduler, so no other task can fire mid-flash and corrupt the radio session. The receive-side timeout is also wrap-safe around the 49.7-day uptime rollover.

Documentation​

  • Updating the NINA firmware reorganised: the new in-device path is Option D and is recommended; the v2.3 passthrough is Option A; the host-side Arduino IDE and arduino-fwuploader paths remain available as Options B and C.
  • System and Tools updated to reflect the menu move; the Menu Tree diagram shows Radio FW Update under System.

v2.3.0​

New Features​

  • TopoDroid integration: the Distance Meter now exposes a Bluetooth Low Energy protocol that TopoDroid discovers and connects to as a first-class device. Each shot you capture on the JedEye streams directly into the survey's shot list, and TopoDroid can also trigger a measurement remotely (handy when the device is mounted on a tripod). The advertised name is JedEye_<serial> and the wire format is the SAP6 17-byte shot frame on JedEye-specific 128-bit GATT UUIDs.
  • Radio FW Update tool: a new entry in OPTIONS > TOOLS puts the JedEye into a USB-to-radio passthrough mode so the radio module's firmware can be updated from a host PC without overwriting the JedEye application firmware. See Updating the NINA firmware.

Requirements​

  • This release requires NINA radio firmware 3.0.1 or newer. Devices shipped with v2.2.x or earlier carry NINA firmware 1.5.0 and must be updated once before the new BLE protocol works. The Distance Meter's Bluetooth icon will not appear if the NINA firmware is out of date.

Improvements​

  • BLE robustness: all BLE writes are now serialised through a single deferred point in the cooperative scheduler, eliminating a class of freezes caused by re-entering the radio's HCI queue from event handlers or deep menu callstacks.
  • Library bumps: ArduinoBLE 1.3.6 → 2.0.2 and WiFiNINA 1.9.1 → 2.0.1, in line with the new NINA firmware family.

Documentation​

  • New page: Updating the NINA firmware, covering the in-device Radio FW Update path, the Arduino IDE Firmware Updater, the arduino-fwuploader CLI, and the Windows PowerShell convenience wrapper.
  • The Distance Meter page has been rewritten to describe the new BLE service, TopoDroid pairing, and the protocol details for third-party apps.

v2.2.0​

New Features​

  • Compass Export: Added support for exporting survey data in Compass (.dat) format.
  • Improved Data Transfer:
    • Per-Section Downloads: Surveys are now downloaded individually via the history list (THE, SVX, DAT) to ensure better data organization and prevent large file handling issues.
  • WiFi Network Management:
    • Added ability to manage local WiFi networks directly from the JedEye Settings webpage.
    • Users can now View, Add, and Remove stored WiFi networks for Station Mode connections.

Improvements​

  • Documentation: Updated user manual to reflect new export options.
  • Web Interface: Refined download options on the main page.
