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:

1. Standard BLE Weight Scale (V5.0) – Official Bluetooth profile
2. 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 kg

Benefits:

• 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

Bluetooth HID Keyboard Weighing Scale

Upgrade your weighing process with our Bluetooth HID Keyboard Scale, designed for seamless wireless data transfer without drivers or additional software.

This smart scale works exactly like a wireless keyboard. Once paired via Bluetooth, it automatically transmits weight readings directly into any text field — including Excel, ERP systems, billing software, web forms, and POS applications on any operating system like Windows, Mac OS, Linux, iPhone, Android etc.

Key Features

• Wireless Bluetooth HID Connectivity
• No Drivers or Software Required
• Direct Data Entry into Any Application
• Plug-and-Play Operation
• Fast & Accurate Weight Transmission
• Compatible with Windows, macOS, Android & Linux
• Up to 10–20 Meter Operating Range
• Auto Reconnect After Pairing

How It Works

The scale pairs with your computer just like a standard Bluetooth keyboard. When a weight is measured, the value is instantly “typed” into the active cursor position, followed by configurable suffix options such as Enter or Tab.

Ideal For

• Industrial Weighing
• Warehouse & Logistics
• Billing Counters
• Packaging Units
• Inventory Management Systems
• Laboratory Applications
