TMD VS. Body Fat Scale

Test Description​

The SDK has observed significantly faster connection speeds with body fat scales compared to TMD devices. This issue is currently under testing, covering the following scenarios:

  • Speed: Bluetooth module connection speed comparison (body fat scale vs. our device)
  • State: Immediately after power-on | After 30 minutes of operation
  • Environment: Interference (hardware operating frequency interference) vs. Normal conditions
  • Device: Same smartphone (Honor), identical central device (BLE)

⬇️ Performance Metrics ⬇️​

Speed: Bluetooth Module Connection Speed Comparison (Body Fat Scale vs. Our Device)​

Connection time comparison for 4 different machine models:

  • Case 1: Connection time statistics for 4 devices in office environment
    Case 1: Connection time in office environment

  • Case 2: Connection time comparison when phone uses same-frequency WiFi (2.4GHz)
    Bluetooth operates at 2.4GHz. When WiFi switches between 5GHz/2.4GHz, same-frequency interference affects Bluetooth connection time and stability.
    Case 2: Same-frequency WiFi interference test

State: Immediately After Power-on vs. After 30 Minutes Operation (TMD devices only)​

Connection time comparison between freshly powered devices and devices running for 30 minutes.
State: Newly powered vs. post-30min operation

Summary​

Current tests show body fat scales have significantly faster connection speeds and higher stability than TMD devices when powered on. TMD devices exhibit longer connection times regardless of power-on state, though both maintain normal detection stability.

  • Body Fat Scales: Consistently connect within 2 seconds, demonstrating stronger interference resistance
  • TMD Devices: Average connection time under 6 seconds, with weaker interference resistance
