What's the USB dongle?
The USB to BLE Bridge dongle is a device by which Bluetooth 4.0 BLE packets are changed to serial communication packets and vice versa.
Bluetooth connection indicator
-
Blink slowly in blue
Wait a connection
The Bluetooth connection indicator is blinking slowly in blue when the USB dongle is plugged into the USB port of a computer.
-
Continuously on with blue
Connected
The Bluetooth connection indicator is continuously on with blue if the USB dongle is connected to a robot.
-
Blink quickly in blue
Data transmission
The Bluetooth connection indicator is blinking quickly in blue while the USB dongle receives data from a robot.
Why the USB dongle is needed?
Pairing is required to connect a robot to a computer through Bluetooth.
Many robots and computers are used in a classroom environment.
If multiple robots are turned on, a computer may be connected to another robot, not to my robot.
Thus we need to pair with a robot by turning on only one robot and then continue the next pairing one by one.
This consumes long time and is complicated.
However, this problem disappears if we use a USB dongle.
Pairing becomes very easy and fast.
A USB dongle finds only its paired robot and is connected to it even if many other robots are turned on.
A computer can be directly connected to a robot if it supports Bluetooth 4.0 BLE.
However, we recommends to use a USB dongle in a classroom.
For a smart phone/tablet, it should support the Bluetooth 4.0 BLE and can be directly connected to a robot without a USB dongle.
