2.4G Body Fat Scale
The 2.4G body fat scale uses a unidirectional uplink architecture. The device uploads weight and body composition data to the mobile app via the 2.4G wireless channel, completing data sync without any pairing. After the user steps on the scale, data is collected and transmitted within seconds, and the app automatically receives and updates the health profile.
This solution significantly simplifies the user workflow by eliminating traditional wireless pairing and reconnection steps, making it ideal for multi-user household scenarios. The device employs ultra-low-power design; four AA batteries can support thousands of weighings, meeting long-term maintenance-free use.
Unidirectional Uplink
Scale actively sends, app passively receives; no bidirectional connection required, reducing power and complexity.
Weigh & Transmit
Transmission triggered automatically after weighing; data syncs to phone in seconds with no manual operation.
SMV Broadcast Series
The SMV broadcast series uses a unidirectional downlink architecture. The mobile app sends control commands to nearby devices via the 2.4G broadcast channel, enabling pairing-free device control. Suitable for smart light strips, remote-controlled toys, display screens, and other scenarios requiring centralized control.
In broadcast mode, one phone can control multiple devices simultaneously, with support for grouping and scene linkage. Devices do not need to maintain connection state; they execute immediately upon receiving commands. The system architecture is simple and reliable. This solution offers significant advantages in exhibitions, retail stores, and smart home scenarios.
Unidirectional Downlink
App actively broadcasts, devices passively receive; one-to-many control without pairing each device.
Instant Control
Commands reach devices in milliseconds, suitable for real-time control and synchronized demos.
Technical Advantages
The 2.4G proprietary protocol offers unique advantages in the smart device space. It establishes connections fast with minimal protocol overhead, suitable for latency-sensitive applications; low power consumption and low cost make it ideal for battery-powered devices. VTrump's 2.4G solution is deeply optimized at the protocol layer, maintaining stable communication even in crowded 2.4G spectrum.
