Walkera has launched the Scout X4 a new control unit for Multikopter on the market. The new ground station consists of the modules BT-2401A (receiver) and BT-2401B (transmitter) and the GCS software (app).
The Ground Station Module BT-2401B seems to contain a full remote control, which is also equipped with a Bluetooth module, which is connected to a mobile phone or tablet (Android or iOS). The whole is controlled by the GCS software. The software is used as an interface for operation of the remote control.
The software offers the normal RC control and autonomous flight modes, so you can start automatically or land program missions over waypoints and much more. In addition, telemetry data are such as speed, altitude, distance and some others available. Unfortunately, the voltage gauge does not work.
In addition to the normal Scout X4 RX709 receiver and the receiver BT-2401A is installed. Both receivers can currently only be operated individually, which seems a little surprising, because the data (so it shows the wiring) are looped basically. In reality, however, it is not possible, the normal station and the new BT-2401B simultaneously bonding. So therefore you have to decide which channel you want to use before the flight.
After our initial tests with different Android devices has unfortunately shown that the software in the current version (Android App, V1009) does not work stable enough. It happens that it crashes or even simply tear off the connection to the receiver. Then you can probably only the transmitter BT-2401B off so that the receiver goes into Failsafe.
It’s like saying if the critical contact between the app and the BT-Ground Station is demolished times. Can not be again “Connecten”, although the software says. Since the connection between the ground station and the copter still exists, the copter will not go into fail-safe mode and therefore does not come back.
