Experience seamless wireless weight measurement with state-of-the-art BLE (Bluetooth Low Energy) scales from Weighing Solutions and Instrumentation. Designed for both commercial and precision applications, our scales transmit real-time weight data directly to mobile devices, tablets, or BLE-enabled systems.
BLE Weighing Scales – Precision Meets Connectivity
We offer two advanced versions:
- Standard BLE Weight Scale (V5.0) – Official Bluetooth profile
- Custom Precision ASCII BLE Scale – Human-readable, 3-decimal precision
1. Standard BLE Weight Scale (0x2A9D)
Perfect for commercial applications and apps that require standard BLE Weight Scale support.
Key Features:
- Official Bluetooth SIG Weight Scale Service (UUID 0x181D)
- Weight Measurement characteristic: 0x2A9D
- Resolution: 0.005 kg (5 grams)
- Real-time BLE notifications for weight changes
- Compatible with apps like nRF Connect, Android BLE apps, iOS BLE clients
Convert to kilograms and encoded as per BLE standard:
Weight = uint16 × 0.005 kg
Example: 250 g → BLE Value:0032 00 → displays as 0.250 kgBenefits:
- Official BLE standard ensures maximum compatibility
- Reliable real-time weight updates
- Ideal for commercial and industrial BLE applications

2. Custom Precision ASCII BLE Scale
Designed for applications requiring high-precision, real-time weight display.
Key Features:
- Custom BLE characteristic: UUID 0xFFF1
- Precision: 0.001 kg (1 gram) (or any other precision also available as per scale capacity and precision).
- Weight sent as ASCII string (e.g.,
"0.251") - Works with nRF Connect or any custom BLE client
- Continuous real-time BLE notifications
Benefits:
- Human-readable display, no decoding required
- Perfect for labs, IoT systems, or custom dashboards
- Full 3-decimal weight precision
