100% of DrinkMates went through our calibration and testing machine, so we make sure they are working right before they are shipped from our factories, but sometimes there are characteristics of certain phones which cause a communication breakdown.
From the initial unboxing, it may take a few tries to get DrinkMate to register successfully, since it has been powered down since the calibration testing.
Wait 7 – 10 seconds after plugging your DrinkMate in. If it does not connect, try flipping it over (i.e. plugging it in upside-down). The Lightning port is reversible, but sometimes the iPhone is sensitive to which side is plugged in.
Check the “about” section of your app and see if there is a serial number registered. If so, but the app still does not allow you to ‘Test your BAC’ then please contact us with your serial number.
DrinkMate is supported on over 10,000 Android devices, but there are still a few cases in which DrinkMate will not be supported. The easiest way to determine if your phone is compatible is by searching the model at GSMArena. Under ‘Specifications’–>’Comms’–>’USB’, if you do not see ‘USB Host’ explicitly stated, then unfortunately this device is not compatible with DrinkMate.
If your device is listed as compatible, and DrinkMate will still not connect, contact us with your phone make/model, and DrinkMate serial number, if listed.
