Due to the short time, it may result in inaccuracies in measuring data and cause large errors. Such large error sleep data does not make much sense to the user. There is no need to design a function to calculate short sleep.
2, we found that many users have not got up in the morning or get up and did not take a few steps to start synchronizing data. Since the wristband has not exited the sleep mode at this time, no sleep data is generated at the end.
It is recommended to schedule the morning data synchronization after washing. The purpose of this arrangement is to ensure that the bracelet exits sleep mode. As long as the bracelet detects enough steps, usually 200~300 steps, it can smoothly exit the sleep mode and generate sleep data.
The right way to measure: Place your arms flat, relax and stay still while keeping your wrists close to your arms.
Note: Individual differences in skin color, hair, tattoos, and scars may also affect heart rate/blood pressure signals when worn correctly.
A：Accelerometers and algorithms built into the bracelet are extremely subtle. In general, when you get the bracelet to download the app, you must fill in the information accurately! Including gender, height, weight, and age, these slight inaccuracies will directly affect the data capture of the accelerometer, further affecting the algorithm operation, resulting in inaccurate counting, incorrect distance data, and low calorie value. This leads to suboptimal data that affects your personal athletic data.
In addition, your swing arm posture, stride length, body shape, flatness of the road surface, and uphill and downhill slopes will all affect the step value.
Q：Why set up WeChat, QQ and other information reminders, but the bracelet is not reminded?
A：WeChat and QQ software information reminders must meet the following conditions:
(1) When the mobile phone is in the sleepless state, the APP background process cannot be closed;
(2) The computer and mobile phone cannot be used online at the same time;
(3) The bracelet is always connected to the mobile phone, and the Bluetooth needs to be always on;
Tip: If you set the DND mode for your friends’ chats alone, the bracelet will not be reminded.
A：The new Android version officially requires us to use the new interface (Android Bluetooth SDK update, to provide higher data protection and improve security levels, increased permissions on Bluetooth, Bluetooth search to the device requires location services), so Android Users of mobile phone systems with 6.0.1 and above need to open the phone location switch to search for the bracelet connection in the app.
A：It is recommended that the handle ring head be connected to the USB interface in the opposite direction, or replace the USB interface of other devices. Try charging in both the positive and negative directions. Because our wristband is inserted into the charging, it can be inserted in both the front and the back. If there is no Reaction, you can try to insert it in reverse (the reverse plugging means that when the current plug-in screen is facing up, the plug-in screen is turned down).
Make sure that the metal contacts on the charging base are in place with the metal contacts on the back of the unit. A charging prompt will appear on the screen when the power is connected. (Can only be used for USB charging of the Carvo bracelet)
2, no need, the bracelet is a lithium polymer battery, there is no memory effect of the nickel-cadmium battery, you can do it with the charge.
For example, if the event reminder is set to 1 group, the alarm reminder can only set up to 19 groups.
There is also a place to pay attention to here, alarm reminders and event reminders cannot be set at the same time.
2. If the data cannot be synchronized, please try the following methods:
First, you can try to pull down the sync operation again. Secondly, please end the App process and then re-enter; if not, please switch the phone Bluetooth or restart the phone. (You can also try to cancel the bracelet device pairing in the phone settings before restarting the phone)
Tip: For Apple users, please check the “Bracelet Model” device in the Bluetooth settings table of the mobile phone, click and ignore the device, then restart the switch to Bluetooth or restart the phone.
