Step 3: Connect the Collector to Wi-Fi

Tap the "+" button in the top-right corner to add a device, then enter your Wi-Fi SSID and password.

TIP

If the device cannot be found:

1. Check that the collector is powered on — the right LED should be lit.
   
2. Check that the left LED is blinking — blinking means it is in pairing mode. (Long-press the left button "B" to clear the saved Wi-Fi and re-enter pairing mode.)
   
3. If you are using an iPhone, connect your phone to a 2.4 GHz Wi-Fi network first. (iOS does not grant apps permission to scan for Wi-Fi networks.)
