Description

Time calibration: Time zone calibrationIn case of no positioning, RTC clock is used. After going online, the user can manually set the corresponding time zone through the APP to update the current time zone of the watch.
Tracking and positioning:

-Hibernation default manual acquisition positioning: The default positioning mode of the device is sleep mode. When entering the map interface, the device will automatically update the location or the watch will immediately upload the current location once after the APP issues an immediate positioning command.

-Fixed upload: The positioning frequency(interval) is 10 minutes or 1 hour. The terminal will acquire the current position according to the currently set positioning interval and upload it to the data platform center. Users can set different positioning intervals through the APP according to their own needs (the shorter the positioning interval, the shorter the watch's standby time).
