Yuyang King Bluetooth App - Full Fixed

The Yuyang King Bluetooth app (known as "Yuyangking" on Android and "Emotor" on iOS) serves as a digital control center for YKZ series brushless DC (BLDC) motor controllers. It bridges the gap between raw hardware and user experience, allowing electric vehicle (EV) enthusiasts to fine-tune their ride's performance, safety, and efficiency directly from a smartphone. Core Functionality and Setup

The app connects to the controller via a dedicated Bluetooth adapter (like the YAZ1403BT). Once paired—often using the default password 12345678—users gain access to a real-time dashboard and a deep menu of programmable parameters.

Connectivity: It supports both BLE and ERD Bluetooth types. Users typically need to enable location services for the app to discover the controller.

Real-Time Monitoring: The main interface functions as a digital speedometer and provides live data on battery voltage and motor status. Performance Tuning Features

The primary appeal of the Yuyang King app is its granular control over motor behavior. Key adjustable settings include:

Start Modes: Users can toggle between Soft Start (smoother acceleration for comfort) and Fast Start (immediate torque for performance), with 10 adjustable grades for each. yuyang king bluetooth app full

Current Limits: To protect components or extend range, both the Battery Current Limit and Phase Current Limit can be adjusted between 50% and 100% of the controller's capacity.

Power Modes: The app features a Power BOOST mode that can increase torque by up to 20%, alongside an ECO mode that reduces current draw to maximize mileage.

Regenerative Braking: The EBS (Electronic Braking System) strength is configurable from grades 1 to 10, allowing riders to customize how aggressively the motor recovers energy during deceleration. Calibration and Safety

Beyond performance, the app is a critical tool for vehicle maintenance:

Speedometer Calibration: Users can perform a precise 5-meter roll test to sync the controller's speed readings with actual GPS data, correcting common inaccuracies in hub motor pulses. The Yuyang King Bluetooth app (known as "Yuyangking"

Protection Settings: The Low Voltage Cutoff is adjustable, preventing battery damage by stopping the motor when the voltage drops below a safe threshold.

Security: A unique Anti-theft feature allows users to electronically lock the motor through the app, preventing the vehicle from being rolled away even if the power is cut. How to Calibrate Yuyang King Bluetooth BLDC Controller

Common Problems and Solutions (FAQ)

2. Features and Functionality

Users often search for the "full" version of the app hoping to unlock hidden hardware features. Here is what the app typically controls:

Music Playback: While you can stream music via Bluetooth from Spotify or YouTube, the Yuyang King app creates a dedicated interface for playing karaoke tracks (backing tracks).
Lyric Display: The primary function of the app is to display lyrics on your phone screen (or cast them to a TV if the speaker supports HDMI/T-Card).
Vocal Effects: The app often allows you to adjust microphone settings, such as:
- Echo depth.
- Microphone volume (independent of the hardware knob).
- Tone/Bass adjustments.
Recording: Most versions of the compatible apps allow you to record your singing session and save the MP3 file to your phone.

Introduction to Yuyang King Bluetooth App

The Yuyang King Bluetooth app is designed to connect and control Yuyang King devices wirelessly through Bluetooth technology. The app provides users with a convenient interface to manage their device's functions, settings, and updates.

3. Battery Saver and Auto-Shutdown

The hardware usually defaults to shutting off after 10 minutes of inactivity. Via the app, you can adjust this timer to 1 minute, 30 minutes, or disable auto-shutdown entirely for use as a permanent USB dongle. Common Problems and Solutions (FAQ) 2

Short review — Yuyang King Bluetooth app (YYK)

Overall: Basic but functional app for configuring Yuyang King/YYK e-bike/scooter controllers. Works for core tasks but feels dated and limited.
Key features: Connect via BLE/ERD, view real-time telemetry (voltage, current, temp, speed, trip), change controller parameters (soft start, speed limits, cruise, direction), calibration tools, firmware/version info.
Usability: Simple UI but clunky; some users report needing multiple attempts to pair and to re-login after initial setup. English in manuals/apps can be awkward or incomplete.
Reliability: Generally works for reading status and applying settings; initial connection (first-time pairing/password 1234) can take 20–40s. Occasional disconnects or failure to detect device reported.
Compatibility: Android and iOS versions exist; Android requires reasonably modern OS (manuals mention >4.4). Some newer modules or firmware may require alternative apps or WeChat in certain regions.
Documentation/support: Sparse official documentation; available user manuals and third-party guides (Scribd, vendor pages). Limited official forum/support.
Safety/limits: App exposes many low-level parameters—use caution when changing values (risk of motor/controller damage or unsafe behavior). Make small incremental changes and test in a safe area.
Who it’s for: Hobbyists and technicians who need direct control of YYK controllers; not ideal for casual users wanting a polished consumer app.

Quick recommendation: Use the app for telemetry and small adjustments, follow the official manual for calibration, and avoid large parameter changes without understanding their effects.

Yuyang King (YYK) Bluetooth App serves as the primary interface for configuring and monitoring Yuyang King high-power BLDC motor controllers. Available on both Android and iOS, it allows users to adjust critical performance parameters such as acceleration, braking force, and speed limits directly from their smartphones. 1. Getting Started: Download & Connection To use the app, you must have a compatible YYK Bluetooth adapter

(e.g., YAZ1401BT, YAZ1402BT, or YAZ1403BT) connected to your controller. : Search for " Yuyangking Google Play Store for Android, or " Apple App Store Connection Steps Turn on the vehicle’s electronic lock/ignition. Open the app and select the Bluetooth type ( ) in the upper-left corner.

Scan for and select your device (often appears as "yangyang King E motor"). Pairing Password : Use the default code (or sometimes 2. Key Configuration Features System Settings " section allows for extensive customization. Acceleration Control : Toggle between Fast Start (hard start) and Soft Start , each with 10 adjustable grades. Speed Management : Set specific Speed Limits (30%–60% of max) and Reverse Speed Limits (10%–100%). Regenerative Braking : Adjust the EBS Braking Force across 10 levels to control electronic braking intensity.
