The range extender is used for the wireless data connection between the MikroKopter and tablet, smartphone, etc..
It can be used for Waypoint flight and other telemety applications.

A smartphone or tablet can be connected via the Bluetooth interface with the range extender.

The MikroKopter connumnicates via 9xxMHz to the RangeExtender. Thus, a large range for MikroKopter (1000 - 2500mtr under good conditions) can be be achieved.

The range extender can be used with several programs ( Dubwise for SmartPhone via Bluetooth,...)
In addition, the range extender is needed for our Android Tablet-Too (MKTT). In the tablet firmware the ID of the RangeExtenders is used to unlock some of the software features (loading and saving of waypoints etc).

In the RangeExtender a NiMH battery with low self-discharge is installed. Means the range extender can work without additional supply over a longer period of time (about 5-8 hours).
When the battery is low on power, a sound signal warns you.
The RangeExtender needs a Power on the USB-Port for charging (PC, Laptop or external power supply)
