Cue App Motion Sensor Pal Mode
This mode provides equivalent functionality to the motion sensor pal.
Use this mode when measuring acceleration continuously or detecting impacts.
This mode is divided into three sub-modes:
- Acceleration measurement mode
- Event detection mode
- Dice mode
Acceleration Measurement Mode
This mode intermittently or continuously measures acceleration and transmits the data.
Settings
| Setting Command | Setting Item | Setting Value | Remarks |
|---|---|---|---|
| t | Transmission interval | 0 or 1–4095 | Unit: seconds. 0: Continuous transmission 1+: Intermittent transmission |
| p | Sensor-specific parameter | x3000yyy | x: TWELITE 2525A mode flag yyy: Accelerometer properties |
TWELITE 2525A Mode Flag
Setting the TWELITE 2525A mode flag to 1 (sensor-specific parameter: 13000000) makes it operate as TWELITE 2525A FIFO (normal) mode. Use this mode if you want to substitute TWELITE 2525A.
Accelerometer Properties
You can change the number of samples and sampling frequency during intermittent transmission with accelerometer properties.
These settings can be combined by adding values.
| Setting Value (Hex) | Description |
|---|---|
| 0x?3????00–0x?3????FF | Number of samples to send during intermittent transmission, set in 16-sample units. Sample count = 16 + 16 x value. Examples: 0x00000000: 16 samples (default) 0x00000001: 32 samples … 0x00000007: 128 samples … 0x000000FF: 4096 samples |
| 0x?3???0??–0x?3???F?? | Sampling frequency of acceleration: 0x00000000: 25Hz (default) 0x00000100: 50Hz 0x00000200: 100Hz 0x00000300: 190Hz 0x00000400–0x00000F00: Undefined |
When the sample count is set to 32 or more, data will be split into separate packets every 16 samples.
For example, if set to 32 samples, two packets with 16 samples each will be received, not one packet with 32 samples.
Parent Device Output
Move Mode
Detects movements like Move and Shake.
You can control the notification pal’s LED.
Settings
| Setting Command | Setting Item | Setting Value | Remarks |
|---|---|---|---|
| p | Sensor-specific parameter | 01100000 |
Parent Device Output
Usage Notes
This mode detects movement and sends data accordingly. Therefore, if moved slowly, it may not detect movement and output may not change. In that case, move it a little more vigorously.
Also, setting sensor-specific parameter (p) to 01000000 makes motion detection more sensitive. If transmissions occur at unintended times, set this parameter to 01000000.
Dice Mode
Detects the face of TWELITE CUE facing upward.
Controls the notification pal’s LED similar to event detection mode.
Settings
| Setting Command | Setting Item | Setting Value | Remarks |
|---|---|---|---|
| p | Sensor-specific parameter | 02100000 |
Parent Device Output
Usage Notes
This mode detects movement and determines the face orientation. Therefore, if moved slowly, the face may not be detected and output may not change. In that case, place it on a desk or give it a light tap.
Also, setting sensor-specific parameter (p) to 02000000 makes motion detection more sensitive. If transmissions occur at unintended times, set this parameter to 02000000.
Typical Battery Life
- About 3.5 years if transmitting once every minute in intermittent transmission acceleration measurement mode
- About 20 days if transmitting continuously at 25 Hz sampling frequency in acceleration measurement mode
- About 3 years if moving once every minute in event detection or dice mode
