WiFi Communications Module with Bluetooth USB MQTT

NextGen WiFi

Wi-Fi Relay Control (NexGen WiFi)

The NexGen WiFi module is NCD's second-generation Wi-Fi solution, built to make connecting and controlling relay boards easier than ever. It combines Wi-Fi, Bluetooth, USB, and MQTT into a single, modern communications module - so you can choose the connection method that works best for your application.

Setup is simple using the built-in Soft AP web interface, where you can enable or disable features, configure networking, and tailor the module to your needs - no extra software required.

One Module. Multiple Ways to Connect.

WiFi Communications

Connect your controller directly to your network using standard TCP/IP communication. Configure DHCP or static IP settings, port numbers, and serial baud rates using the integrated web interface while in Soft AP mode.

Soft AP configuration works on phones, tablets, laptops, and desktops, making setup fast whether you're in the field or at your desk. Once configured, you can exit Soft AP mode and control relays through supported protocols or a basic built-in web control page.

Bluetooth Communications

Prefer wireless without the network? NexGen WiFi also supports Bluetooth Classic using the Serial Port Profile (SPP). Your controller appears as a standard virtual COM port, allowing easy wireless communication with a PC.

Bluetooth name and PIN settings can be customized through the web interface.

---

USB Communications

For direct, plug-and-play control, the NexGen WiFi module includes a USB port. It mounts as a virtual COM port, giving you reliable wired access using standard serial communication - perfect for setup, testing, or local control.

Supported Communication Protocols

MQTT

The NexGen module supports lightweight MQTT messaging for remote control and monitoring. Configure basic authentication and define one publish and one subscribe topic using the web interface. Commands are received via the subscribe topic, with responses published back automatically.

---

HTTP API

Send commands using simple HTTP requests - even from a web browser. This makes it easy to trigger relay actions or integrate with existing web-based tools and systems. Simply send the HTTP command to the IP address 192.168.1.10 in any web browser using the following command structure: 192.168.1.10/sendCommand?data:[254,108,1]

---

Web Socket

For real-time communication, establish a WebSocket connection to the controller. Send commands as JSON arrays and receive responses in the same format, making it ideal for dashboards, web apps, and live interfaces.

---

Discovery, Status & Diagnostics

Automatic Network Discovery

The NexGen module broadcasts UDP discovery packets, allowing tools like Base Station - and your own software - to quickly find devices on the network.

---

RGB Status LED

An onboard RGB LED provides instant visual feedback for power, connectivity, and configuration states - making troubleshooting fast and intuitive.

---

Time Sync (Taralist Controllers Only)

When used with compatible Taralist controllers, NexGen WiFi can automatically sync the onboard real-time clock using NTP. Time is updated daily over the internet to keep schedules accurate without manual adjustment.

---

Compatibility & Requirements

• 2.4GHz Wi-Fi only (5GHz networks not supported)
• Compatible with Fusion series controllers
• Fully compatible with G2 revision boards (G2A, G2B, G2C, etc.)
• Not compatible with older, non-G2 relay boards due to power requirements

⚠️ Important: This WiFi module draws more power than older controllers can supply. Newly purchased controllers include the required power upgrades. Retrofitting older devices may require a power supply upgrade and service charge.

Please consult Relay Pros staff before attempting to retrofit older hardware.
