Connect an Instrument

PhotosynQ for Android connects to a MultispeQ through Bluetooth. The same connection is used for Projects, Quick Measurements, and MultispeQ QC.

Using an iPhone? Follow PhotosynQ for iOS. The iOS app requires the MultispeQ Saddle (Dongle) between the phone and MultispeQ.

Before connecting

1. Charge the MultispeQ and phone.
2. Turn on the MultispeQ by pressing and holding the center power/reset button on the rear panel for approximately five seconds.
3. Enable Bluetooth on the phone.
4. Allow PhotosynQ to access Nearby Devices or Bluetooth when Android requests permission.
5. If scanning is unavailable or finds no device, check the app's Location permission and the phone's Location setting as well.

Select a MultispeQ

1. Open Measure in the bottom navigation and select Connect MultispeQ. If an instrument is already connected, select Manage Connection.
2. Select Scan Devices and wait for the nearby-device list to refresh.
3. Look under Nearby Devices for powered MultispeQs detected during the scan.
4. Expand Known Devices when reconnecting an instrument that this phone previously paired with.
5. Match the final characters of the device ID shown in the app to the identifier on the MultispeQ.
6. Select the instrument.
7. If Android requests a pairing PIN, enter 1234.
8. Wait for the paired-device screen before starting a measurement or QC test.

The device list separates nearby instruments from previously paired instruments. The device-selection screen may differ slightly across Android versions.

Previously paired instruments remain available under Known Devices, even when they are not currently powered on. A known device must still be on and available before the app can connect to it.

The connected-device screen shows the selected instrument, device ID, firmware details, power control, and Choose Another Device action. It does not display a battery reading.

The instrument remains paired with Android. On later uses, turn it on and select it from the list; the PIN normally is not requested again.

Change instruments

Open Measure → Manage Connection, then select Choose Another Device. Select the intended device from the list. QC reports are associated with device IDs, so changing instruments does not mix their reports.

Troubleshooting

• Confirm that the MultispeQ is charged and powered on.
• Keep only the intended MultispeQ powered on while pairing.
• Confirm PhotosynQ has Nearby Devices or Bluetooth permission. If the scan still fails, also check Location permission and the phone's Location setting.
• Select Scan Devices again after a few seconds.
• If another phone is connected, disconnect it or restart the MultispeQ before connecting from this phone.
• If the app remains on Connecting, return to the device list and select the instrument again.
• A very low MultispeQ battery can cause an unstable Bluetooth connection.

QC after connecting

After establishing a connection, run MultispeQ QC before collecting field measurements.
