In embedded development, IoT device testing, and industrial field maintenance, engineers frequently switch between serial monitors, Modbus debugging software, and waveform plotting tools. This workflow involves tedious setups and often leads to missing critical anomaly events in extensive log outputs.
To address these challenges, Beijing YiLink Technology Co., Ltd. has officially launched yiSerial WebConsole, a lightweight, highly efficient browser-based debugging tool. Without downloading desktop clients or installing drivers, engineers can debug serial ports and Bluetooth Low Energy (BLE) devices seamlessly using modern browsers such as Chrome and Edge.

Key Features & Highlights
- Zero-Installation Web Access with Dual Channels: Powered by Web Serial API, it supports standard baud rates, data bits, parity, and hardware flow control (RTS/DTR), alongside auto-reconnect memory. It integrates Web Bluetooth to scan and subscribe to BLE GATT characteristic channels for wireless data transfer and real-time logging.
- Multi-Level Keyword Highlighting & Log Filtering: Offers keyword highlights, line coloring, and background highlighting to spot anomalies instantly. Supports multi-line logical AND (&) / OR (|) filters and permanent discard mechanisms to minimize memory usage.
- Comprehensive Modbus Master & Slave Debugging: Modbus Master mode supports batch read/write for coils, discrete inputs, and holding/input registers across Hex, Bool, Float, Int16/32, Double, and scaled engineering units. Built-in Modbus Slave emulation allows instant virtual slave mockups to test host protocols and communication loops.
- Real-Time Data Curves & Visual Analytics: Built-in dynamic plotting canvas for monitored registers and text logs, featuring auto-scaling and pre-processing scripts without needing third-party plotting applications.
- Profile Market & Quick Command Management: Commands support plaintext, Hex, C scripts, and auto-CRC/checksum appending. Easily import and export configuration profiles for batch deployment and routine inspection.

Typical Application Scenarios
- Embedded R&D & Diagnostics: System boot tracing, low-power sleep/wake cycle monitoring, protocol stack log capture, and intermittent bug isolation.
- Industrial Fieldbus & Modbus Equipment Commissioning: Parameter tuning, register polling, and telemetry curve analysis for temperature controllers, inverters, smart energy meters, and sensor gateways.
- Production Testing & Field Maintenance: Eliminate complex software installations for field service engineers—open the browser to execute standardized test command profiles with one click.
