Byte Layout and Decode

Payload length is 41 bytes.

function decodePayload(dataView, offset = 0) {
  // Parse flags (24bit) according to Bluetooth format rules.
  const instantaneous_speed = dataView.getUint16(offset + 0, true);
  const average_speed = dataView.getUint16(offset + 2, true);
  // Parse total_distance (uint24) according to Bluetooth format rules.
  const step_per_minute = dataView.getUint16(offset + 4, true);
  const average_step_rate = dataView.getUint16(offset + 6, true);
  const stride_count = dataView.getUint16(offset + 8, true);
  const positive_elevation_gain = dataView.getUint16(offset + 10, true);
  const negative_elevation_gain = dataView.getUint16(offset + 12, true);
  const inclination = dataView.getInt16(offset + 14, true);
  return { flags, instantaneous_speed, average_speed, total_distance, step_per_minute, average_step_rate };
}

Use Cases and Integration Notes

Implementation Checklist

• Validate payload length and mandatory fields before decode.
• Decode with Bluetooth-specified signedness, unit, and exponent handling.
• Convert units at presentation boundaries to avoid drift in business logic.
• Persist raw packets and decoded values for reproducible troubleshooting.
