The System Info screen provides real-time diagnostic information about your WDD-LITE. Use it to check signal quality, verify firmware versions, and confirm the link is healthy. Open it from the menu (long-press the screen or tap the gear), then select System Info.
Diagnostic Fields
| Field | Description | Typical Values |
|---|---|---|
| Model | Device model identifier | WDD-LITE |
| Firmware | Currently installed firmware version | e.g., 4.1.0 |
| Hardware | Hardware revision of the WDD-LITE | e.g., 1.0 |
| Connection | Current link status | Connected / Reconnecting / Connecting |
| Signal | Wireless signal strength from the base station | Measured in dBm (see Signal Quality below) |
| Messages TX | Total messages sent to the base station since power-on | Increases continuously during normal operation |
| Messages RX | Total messages received from the base station since power-on | Increases continuously during normal operation |
| Channel | Current wireless channel | 1-11 |
| Frequency | Wireless frequency for the current channel | 2412-2462 MHz |
| Ch. Hopping | Whether automatic channel hopping is supported | Yes (base station firmware 3.0.0+) or No |
| Encrypted | Whether encrypted communication is active | Yes or No |
| Free Memory | Available system memory | Higher is better |
The dynamic fields (Connection, Signal, Messages TX/RX, Channel, Frequency, Free Memory) update automatically every 2 seconds while the screen is open. To leave the screen and return to the menu, swipe right or tap the title.
The base station's own identity and firmware versions (model, hardware, CPU firmware, manufacture date, name, and so on) live on the separate Base Info screen, not here. See Menus and Settings.
Reading the Diagnostic Fields
A few fields are worth understanding before you act on what you see:
- TX and RX counters reset on power-on: both counters start at 0 each time the WDD-LITE powers up. A low count simply means the device booted recently.
- Encrypted = Yes requires a successful key exchange: even with encryption enabled, the field reads No until the base station completes the key exchange. If it stays No while clearly connected, re-pair (Advanced > Forget Base) so a fresh exchange happens.
- Disconnected behavior: when the WDD-LITE is not connected, the Signal value is stale (it holds the last reading) and Ch. Hopping shows No because the base station's capability information is not available. Treat both as undefined while disconnected.
- Messages RX as a link-quality signal: if Messages TX keeps climbing but Messages RX is stalled, the link has dropped in the receive direction. This is often an earlier warning sign than the Signal field, which only refreshes when a packet is received.
- Channel can change on its own: when channel hopping is active, the base station may move the link to a quieter channel mid-session, so the Channel field changes. This is normal.
Signal Quality
The Signal field shows the received signal strength from the base station in dBm (decibels relative to one milliwatt). This is a negative number; closer to 0 means a stronger signal.
| Signal Strength | Quality | Notes |
|---|---|---|
| -30 to -50 dBm | Excellent | Very close range, ideal |
| -50 to -65 dBm | Good | Reliable connection |
| -65 to -75 dBm | Fair | Generally reliable, may have occasional delays |
| -75 to -85 dBm | Weak | May experience intermittent disconnections |
| Below -85 dBm | Poor | Likely to experience frequent disconnections; reposition the WDD-LITE |
If you see Fair or worse readings and the location cannot change, common 2.4 GHz interference sources to consider: an active microwave oven nearby, a neighboring WiFi access point on the same channel, USB 3.0 devices and cables (a known 2.4 GHz emitter), and Bluetooth audio devices in the same cabin. Moving the base station's antenna away from these, or changing the base station's WiFi channel from the LF Audio AuralSync app, usually helps.
Message Counters
The TX (transmitted) and RX (received) counters help diagnose communication issues:
- Healthy operation: both counters increase steadily. TX rises every few seconds (keepalive pings, info requests). RX rises frequently as the base station sends telemetry.
- TX increasing but RX stalled: the WDD-LITE is sending but not receiving. The base station may be out of range or powered off.
- Both counters stalled: the wireless link is not active. Check the connection status.
Channel and Frequency
The WDD-LITE communicates on a specific channel (1-11), each corresponding to a frequency in the 2.4 GHz band. The automatic channel scanner selects the channel with the strongest signal from the base station. If channel hopping is supported (base station firmware 3.0.0 or newer), the system can switch to a better channel when interference is detected; the Channel and Frequency shown here reflect the active channel at that moment.
When to Check Diagnostics
- After installation: verify signal strength and confirm the connection is healthy
- When experiencing disconnections: check signal strength and the message counters
- Before contacting support: note the firmware version, hardware version, signal strength, and encryption status
- After a firmware update: confirm the new firmware version is installed
If the signal strength is consistently weak, try repositioning the WDD-LITE or the base station to reduce the distance or remove obstructions between them. See Troubleshooting for more connection-issue solutions.
