Measure with a Bluetooth laser meter

The browser's list shows only devices whose Bluetooth name starts with a make or word the app knows — DISTO, Leica, STABILA, LD 520, GLM, Bosch, PLR, TLM, Stanley, Laser, BLE, Distance or Meter. The name decides how a meter is read; a meter named like one make but built like another is tried against the other known makes before the link gives up.

Where the browser cannot reach Bluetooth, the laser button is grey and tapping it says why, once: on an iPhone or iPad "iPhone and iPad browsers cannot connect to a laser meter. Type the measurements instead."; in Firefox and other browsers without Bluetooth "This browser cannot connect to a laser meter. Use Chrome or Edge on Android or a computer, or type the measurements."; and on a page not opened over HTTPS "HTTPS required. Access Odoo via HTTPS or localhost to use Bluetooth." Typing the sizes works on every phone.

A reading goes only into the box you chose, and only while that box is on screen and open for typing: never into a folded section, a read-only box or an item you have left. After a width, the height is next; after that, tap the next box yourself. A reading with no box chosen is refused with "Tap the box the reading is for (W, H…), then measure again." While the app is changing item — saving the one on screen and opening another, adding or splitting — a reading is refused with "Reading ignored while changing items: measure again." Readings of zero, below zero or above 500 m are ignored.

How the size arrived is recorded with it. A save that carries a laser reading records Measured Via Laser meter, the meter's name as the Measuring Device (up to 64 characters) and the time as Measured At, even when the reading only confirms the figure already there. Typing over a laser figure makes it Typed by hand again and forgets the meter. The office sees the same facts in the item's details on the survey form.

When a meter does not behave, or before trusting a new model, the test mode shows exactly what it sends. Add ?laser_test=1 to the address of the measuring page — for example /my/surveys/<id>/measure?laser_test=1 — and open it. The mode then stays on in that browser tab until you open a page with ?laser_test=0 or close the tab.

In test mode the browser's list shows every Bluetooth device nearby, not only known meters, and a Laser test panel opens across the top of the measuring screen with Copy, Clear and a button that folds it to its title and line count. With the time on each line, it records the device's name and the make it was read as; the services and characteristics the browser may read, and what each can do; the characteristic readings come from; and every frame the meter sends, in hexadecimal, with what each make would read from it and whether it was used — for example => 2456 mm used, or not a reading. An unknown meter stays connected, and every characteristic that sends anything is listened to. The panel keeps the last 300 lines and reads left to right in Arabic too.

Connect the meter, measure a few times, then take a screenshot — or press Copy and paste the text — and send it to the office or to support: that trace is what shows whether a model can be read. When copying is not allowed the panel says "Could not copy: take a screenshot instead." Clear empties the panel, and ?laser_test=0 ends the test mode.

The laser button is grey — this browser cannot reach Bluetooth; see Phones and browsers above. Use Chrome or Edge on Android, or type the sizes.

The meter does not appear in the browser's list — it is off, its Bluetooth is off, it uses classic Bluetooth only (a GLM 100 C, for one), or its name does not start with a make the app knows. Open the page with ?laser_test=1, which lists every device, and send the trace.

A Bosch connects but no reading arrives — the Bosch readings are built from public notes and not yet confirmed on a real meter. Measure a few times in the test mode and send the screenshot.

The reading went into the wrong box, or nowhere — tap the right box before measuring; after the height, no box is chosen until you tap one.
