 What is the difference between Master device and Tracker device?

   The first paired device will become the Master device, which is used to receive position radio communication from the tracker and relay the information to your mobile phone through bluetooth. Please keep Master device within bluetooth range of your mobile phone. After adding your first device, every additional device you register will become Tracker devices. The default work mode for Tracker devices is "Live Tracking".

   Tracker devices have 6 work modes; Message mode, Live Tracking mode, Beacon mode, Location on demand mode, 6-level alarm mode, Relay mode.


STEP 5: Check FEW THINGS Before Configuring MASTER and TRACKER

  • Please make sure both Master and TRACKER are in BLUETOOTH connection. Radacat only supports configuration in Bluetooth environments.
  • If the devices are paired to your APP for the 1st time, please make sure you keep both devices with BLUETOOTH connection to your mobile phone for 3~5 mins in order to finish the Ephemeris download. This process should be ONCE only.
  • Make sure the FIRMWARE version is LATEST. If not, please click the FIRMWARE download icon that appears beside the battery charge icon. 


        There are 6 work modes in the system. The LIVE TRACKING is the default one and most popular one. Please find details for those 6 work modes and select the right work mode for your TRACKER to fulfill your needs. Keep in mind that MASTER doesn’t need to set WORK MODE.

    Most work modes need to set a pop-up configuration of “Tracking Interval”.       The Tracking Interval is how often your C2 MINI device sends location information.


    Tip: You can set longer interval times to preserve battery life.

    What is Message mode?

           A device in Message mode could enable guest users without accounts to use it. Other users could select "Tourist mode" on the login page and connect to the device to send and receive messages. Suitable for outdoor offline communication, such as outdoor exploration, mountaineering, fishing, skiing and some other activities.

     What is Live Tracking mode?        

    Live Tracking mode enables real-time positioning. Place the device on items that need to be monitored, such as vehicles, elderly people, children, pets, etc. The Master device will query the location according to the set tracking interval time, or you can manually query the location at any time.

     What is Beacon mode?

            Beacon mode allows periodic location detection at intervals longer than Live Tracking mode. Place the Tracker device on items that require periodic monitoring, such as luggage, valuables, bicycles, small vehicles, etc. The Tracker Device will automatically update its location to the App.

     What is Location on demand?

           The Location on demand mode alerts the user when a Tracker becomes too far away from the Master device. Place the Tracker device on items that have location requirements but do not need real time locating. It is mainly used to prevent loss, such as carry-on luggage.

     What is 6-level alarm mode?

           The 6-level alarm mode has 6 levels of motion sensitivity. The Tracker device could be put on stuff which to be protected from theft or damage, such as bicycles, motorcycles and other valuable personal items. The sensitivity can be adjusted from level 1 to 6, indicating the amount of movement needed to register an alert. When motion of level surpassing the current sensitivity level is detected, it will send information to your Master device and App.

     What is Relay mode?

       Relay mode can extend the communication distance and forward the information sent by other Trackers. In this mode, it will not automatically send alerts to the Master device but instead require you to manually query to obtain location of any other Tracker devices in range of the Tracker in Relay mode.

    What kind of GPS accuracy should I expect?

           We strongly advise you to visit the Official GPS Website  that clearly explains how the GPS technology works, not only for Radacat C2 MINI but for any other device that features GPS technology (like other GPS trackers and smartphones). Basically, the Official GPS Website states that GPS accuracy depends on the amount of obstacles between the GPS satellites and the device itself (which, in our case, is the Tracker). Good GPS accuracy: open outdoor areas (beaches, parks or plains. Bad GPS accuracy: very dense areas (forests or very crowded urban environments); cloudy weather. Indoor use-case is not advisable.

         Is there any requirement or advice for the environment of using C2 Mini?
