Wireless screen casting is an essential feature of interactive flat panels, enabling seamless content projection from smartphones, tablets, and laptops. This capability is achieved through either software or hardware solutions. In this blog, we will focus on hardware-based wireless screen casting, particularly using dongles, and explore common issues users may face, along with practical solutions and tips for enhancing the overall experience.

What is Hardware-Based Wireless Screen Casting?

Hardware-based wireless screen casting relies on a dongle to establish a connection between the interactive flat panel and the source device, such as a laptop or PC. This method is preferred for its reliability and ease of use, especially in environments like classrooms and conference rooms where stable and fast connections are critical. The dongle serves as a bridge, utilizing the interactive flat panel’s built-in Wi-Fi module and hotspot to facilitate data transmission.

However, like any technology, hardware-based screen casting can encounter challenges. Addressing these effectively ensures a smoother user experience.

Common Issues and Their Causes

Wireless screen casting problems can disrupt workflow and productivity. Below are some of the most frequent issues and their potential causes:

1. No Response During Screen Casting

Cause 1: The interactive flat panel’s hotspot is not activated.

Cause 2: The Wi-Fi module is not installed, especially in models like S9 (pro )and M8 (pro ) and M9 (pro ) Series interactive digital whiteboard.

Cause 3: The pairing process is performed incorrectly.

Cause 4: The hardware dongle is damaged.

2. Dongle Does Not Blink

This typically indicates a failure in the dongle’s operation or improper connections.

3. Laptop Screen Fails to Cast

Even when the setup appears complete, screen casting may not work if the pairing sequence is disrupted, or the dongle hardware is malfunctioning.

Detailed Solutions and Best Practices

To resolve these issues, follow the step-by-step guidelines below:

Step 1: Ensure Wi-Fi and Hotspot Are Activated

The interactive flat panel’s built-in 5G Wi-Fi module and hotspot must be enabled for wireless screen casting to function. The connection relies on these features to facilitate data transmission. To ensure they are activated:

Access the system settings on your interactive flat panel.

Navigate to the Wi-Fi and Hotspot menu.

Confirm that both Wi-Fi and hotspot options are toggled ON.

Without these features enabled, all wireless screen casting attempts will fail.

Step 2: Verify Wi-Fi Module Installation

Certain interactive flat panel models, such as the S9, M8, and M9 Pro series, feature detachable Wi-Fi modules. Users need to ensure that these modules are properly installed before attempting to screen cast:
 Check the physical installation of the Wi-Fi module. Ensure it is securely attached to the panel.

Verify in the system settings that Wi-Fi and hotspot are activated.

If the module is missing or not installed correctly, wireless screen casting will not function.

Step 3: Correct the Pairing Process

The pairing process is crucial for successful hardware-based screen casting. Follow these steps to pair the dongle correctly:

Insert the dongle into the front USB port of the interactive flat panel.

Observe the dongle’s light—it should start blinking, and the screen will display a “Pairing” message.

Wait until the pairing process is complete. The dongle’s light will stop blinking, indicating successful pairing.

Remove the dongle from the panel and insert it into the USB port of your laptop or PC.

Repeat the pairing process on your laptop. Follow any on-screen prompts to complete the setup.

Once paired, press the button on the dongle to begin screen casting.

Important Note: Always pair the dongle with the interactive flat panel first before pairing it with the laptop or PC. Reversing this sequence will result in pairing failure.
 

Step 4: Address Non-Blinking Dongle

If the dongle does not blink when inserted into the interactive flat panel:

Inspect the dongle for physical damage or loose connections.

Check the internal wiring of the dongle. Repeated bending of the wires may cause disconnection.

If the dongle is damaged beyond repair, replacing it is the only solution.

Step 5: Regular Maintenance

To prevent future issues, regularly inspect the dongle and related components for wear and tear. Promptly address any hardware problems to ensure continued functionality.

Benefits of Wireless Screen Casting with Hardware Dongles

Wireless screen casting offers numerous advantages, including:

Quick Setup: Hardware-based solutions are typically plug-and-play, reducing setup time.

Seamless Collaboration: Enables real-time sharing of presentations, documents, and videos in meetings and classrooms.

Enhanced Mobility: Eliminates the need for physical cables, allowing users to move freely while presenting.
