PART IV · MEMBER KIOSK

Grip and heart-rate devices

Draft — screenshots coming

Two checkup tests use Bluetooth hardware: grip strength reads an InGrip hand dynamometer, and the cardio tests read a standard Bluetooth heart-rate strap. Staff pair each device once from the kiosk's admin panel — after that, members never see a Bluetooth picker: the test simply connects to the gym's device, with manual entry as the fallback.

What you'll do

Pair both devices to a kiosk and verify a member test picks them up.

You'll need: the kiosk's staff PIN, an InGrip dynamometer with charged batteries, and a Bluetooth heart-rate strap.

Steps

  1. Open the kiosk's staff panel (long-press the welcome screen), enter the PIN, and find the DEVICES section: Grip dynamometer and Heart-rate strap, each showing Not paired or the paired device's name.

    The Kiosk admin staff panel: SECURITY with a Change PIN row, DIAGNOSTICS showing the kiosk Device ID, PREFERENCES with a Sounds toggle switched on, then the DEVICES section with Grip dynamometer - Not paired, tap to set up the InGrip - and Heart-rate strap - Not paired, tap to set up the cardio strap - above the ACTIONS section starting with Force re-sync.
    The DEVICES rows in the kiosk staff panel.

  2. Tap Grip dynamometer. Turn the InGrip on and squeeze it once to wake it — the kiosk scans and lists it. Tap Use this dynamometer; the screen confirms with a live reading when you squeeze.

  3. Back in the panel, tap Heart-rate strap. Put the strap on (or wet its contacts) so it starts transmitting, wait for it to appear, and tap Use this strap — the screen shows a live heart rate once connected.

  4. Verify as a member would: sign in, open Checkup, and start the grip test. It should show the device connecting on its own, then live readings as you squeeze — no picker, no prompts.

  5. Do the same for Resting heart rate — the test connects to the paired strap and shows a live pulse.

What you should see

Both rows in the staff panel show Paired: with the device name, and member tests connect within a few seconds of starting — members never interact with Bluetooth at all.

If something goes wrong

  • The kiosk keeps "Looking for the InGrip dynamometer…" — the device sleeps quickly: turn it on and squeeze once to wake it, then Re-scan. Check the batteries.
  • The strap never appears in the list — a heart-rate strap only transmits while worn; put it on or wet the contacts first.
  • The test says the device is unavailable — the paired device is off, out of range, or taken by another screen; use manual entry to finish the member's test, then re-check the pairing from the staff panel.
  • Readings are erratic — for the strap, dry contacts are the usual cause; for the InGrip, fresh batteries.
