If you are unable to connect a Go Direct SpectroVis Plus to a device via Bluetooth wireless technology, please check the following:
1. Are you using Spectral Analysis 4 app, version 4.4 or newer? Go Direct® SpectroVis® Plus Spectrophotometer, order code GDX-SVISPL, $399, will only connect via Bluetooth wireless technology using Spectral Analysis 4 app, version 4.4 or newer. Visit https://www.vernier.com/spectral-analysis for availability information.
2. Does your device (computer, Chromebook, Android, or iOS device) meet the hardware and operating system requirements? Visit https://www.vernier.com/spectral-analysis for these requirements.
3. Some Go Direct SpectroVis Plus Spectrophotometers will require an update to connect via Bluetooth wireless technology. To determine whether your spectrometer requires and is eligible for this update, see:
TIL 4149: Does my Go Direct SpectroVis Plus Spectrophotometer firmware need to be updated?
4. Make sure you are set up properly for Bluetooth connection:
a. Make sure the battery is fully charged by charging it overnight with the AC power supply. When fully charged, the battery indicator light should be green.
b. Unplug from AC power and press the power button. The green power LED should come on followed shortly by a blinking blue Bluetooth indicator LED.
c. Open Spectral Analysis and tap on Connect Spectrophotometer. Connect to your spectrometer from the list of discovered devices.
Note: Bluetooth will work when plugged into AC power but it will NOT work when plugged into USB. Make sure the USB cable is unplugged if trying to connect via Bluetooth.
