Telemetry & Buffer

Release Threshold - 12.0 g

Impulse threshold for bow release detection, set in BLE firmware.

Follow-Through - 1.5 s

Post-release recording delay before freezing trace.

Trace Buffer Rate - Device 52 Hz / Web 208 Hz

Same capture setting for firmware recovery and browser shot review; the browser stores a higher-rate local trace.

Live Stream Rate - 1110 Hz (Max)

Telemetry frame transmission rate over BLE.

Persist Traces Offline (RRAM)

Saves traces to non-volatile flash so they survive deep sleep power down.

Module Mount Orientation

XIAO position on bow

Preview the selected board mounting direction before updating firmware axis mapping.

View roll - 0 deg

Bow X - 0.00

Bow Y - 0.00

Bow Z - 0.00

Bow X IMU X Bow Y -IMU Z Bow Z IMU Y

Firmware-computed BLE/serial angles need the same mount mapping compiled into the device.

3D Model Alignment

Adjust only the imported bow model. Use this when the sensor data is right but the Blender bow leans, rolls, or pitches the wrong way.

Power Management

Wake-up Sensitivity - 2.0 g

Acceleration threshold needed to wake the chip from deep sleep.

Sleep Timeout - 300 s

Idle duration before sleep when disconnected.

Sleep Sensitivity - 0.15 g

Movement threshold to keep device awake while idle.

Enable Device Auto-Sleep

If disabled, the device remains awake indefinitely until powered off.
