6.3. gForce and Arduino development board (additional purchase required)
gForce Joint acts as a Bluetooth Center and can automatically establish a connection with
gForce Pro Armband through Bluetooth BLE for data transmission. gForce Pro sends the
recognized gesture index and quaternion values to gForce Joint. gForce Joint forwards the received
gesture index and quaternion values to the next level through its COM port (TX). Arduino receives
gesture index and quaternion values from gForce Joint through its COM port (Rx) .
6.4. Key points of using gForce Pro Armband
6.4.1. When using gForce Armband, it should be close to the skin and worn in the middle of
forearm.
6.4.2. In the power OFF state, press the switch button gently, the armband starts, the green
indicator light is on, and it flashes slowly; in the power ON state, press the switch button
lightly, and set the gyroscope as the current direction.
6.4.3. In the power ON state, long press the switch button for five seconds to release, the
armband is closed, and the green indicator light is off.
6.4.4. When charging the armband, the red charging indicator light is on; when charging is
completed, the indicator light is off.
6.4.5. When connecting the armband to OTrain, try to be as close to Dongle as possible. When the
green indicator light flashes, it indicates that the connection is successful.
6.4.6. In the process of training gestures in OTrain platform, when switching from one gesture to
another, the green light is always on, indicating that the new gesture training mode has
been entered, and the training can be started.
6.4.7. When making gestures, gestures need to be performed when the user's arm muscles are
relaxed.
