D6500 Series — WiFi Timer Setup and Troubleshooting
Applies to: D6500, D6520, D6530, D6540, D6560
1. Initial WiFi Setup (First-Time Configuration)
Symptom
Display has never been connected to a WiFi network; app cannot communicate with the display.
Cause
Out of the box, the display broadcasts its own temporary setup network ("SoftAP" or "MicroframeSetup") and must be configured to join your local WiFi network before normal app control is possible.
Solution
- Power on the display.
- On your mobile device, open WiFi settings and connect to the network named SoftAPxxxxxx or MicroframeSetup (broadcast directly by the display).
- If using a phone with mobile data: Temporarily turn off mobile data (cellular data). This prevents your phone from automatically switching away from the setup network to your cellular connection.
- Open the D6500 app.
- Navigate to the Displays tab.
- Tap the [ > ] button next to your display, then tap Display Setup.
- Select your WiFi network name from the list (or type it manually) and enter your WiFi password.
- Optionally, set a display name and PIN.
- Tap Save and wait approximately 30 seconds for the display to connect.
- Reconnect your phone/tablet to the same WiFi network you just assigned to the display.
- Open the app — your display should now appear and be controllable.

2. Factory Reset the Display
Symptom
The app cannot reach the display, WiFi credentials have changed, or the display needs to be moved to a different network.
Cause
The display retains its previous network configuration and must be reset to re-enter setup mode.
Solution
- Locate the button on the back of the display.
- Press and hold the button. The display will show a countdown: 5…4…3…2…1…RST.
- Release the button and wait approximately 10 seconds.
- The display will return to setup mode and begin broadcasting the SoftAPxxxxxx or MicroframeSetup WiFi network.
- Follow the steps in Section 1 to reconnect to your WiFi network.
Note: After a factory reset, the setup network name shown is MicroframeSetup on newer firmware. If you do not see "SoftAP," this is normal.
3. App Cannot Find the Display After Initial Setup
Symptom
Display was previously working, but the app no longer shows it or cannot connect to it.
Cause
The display's IP address may have changed (common with DHCP networks), or the app has a stale entry with an outdated IP.
Solution
- Make sure your phone/tablet is connected to the same WiFi network as the display.
- Open the D6500 app and navigate to the Displays tab.
- Tap the magnifying glass () icon at the top of the Displays tab. The app will scan the network and update the display's IP address automatically.
- If the display is found and shown in red, delete that entry and re-add the display by its IP address if needed.
To prevent this from recurring: Reserve (statically assign) the display's IP address in your router settings so it does not change. Contact your network administrator or internet service provider for assistance with IP reservation.
4. App Shows "Err Save Settings" or "Failed to Read Settings"
Symptom
When attempting to save WiFi settings in the app, error messages appear: "Err save settings" or "Failed to read settings from [display]".
Cause
This error typically occurs when:
- The display is connected to a guest WiFi network with client isolation (devices on the same network cannot communicate with each other), or
- The phone is no longer connected to the same network as the display during the save process.
Solution
- Confirm that your phone and the display are on the same network — not a guest network. Guest networks often block device-to-device communication.
- If the display is on a guest network, perform a factory reset (see Section 2) and reconnect it to a private/standard WiFi network.
- If your facility's network blocks unknown devices, contact your network administrator to allow the display's MAC address, or set up a dedicated WiFi router for the display(s).
- As a temporary workaround, you can control the display directly by leaving it in SoftAP/setup mode and connecting your phone to the SoftAP network — without saving a network configuration.
5. Display Drops Off the App / Intermittent Connection
Symptom
The display connects initially but drops off the app after a period of time.
Cause
Possible causes include:
- The display's IP address changed (DHCP lease renewed)
- The app has a duplicate or stale display entry
- The phone switched networks or the app's local network permission was disabled
Solution
- Check that your phone/tablet's Local Network permission is enabled for the D6500 app:
- iPhone/iPad: Go to Settings → Privacy → Local Network and verify the D6500 app is toggled on.
- Close the D6500 app completely and reopen it (do not just switch away — fully close/swipe away the app).
- Tap the magnifying glass in the Displays tab to refresh the display list and update any changed IP addresses.
- If there are duplicate display entries, delete the one shown in red (incorrect IP).
- Reserve the display's IP address on your router to prevent future IP changes (see Section 3).
6. Display Not Connecting — Missing or Damaged Antenna
Symptom
Display cannot connect to WiFi or has very poor range, even after correct configuration.
Cause
The WiFi antenna may be missing, loose, or damaged. Without the antenna, the display's WiFi radio cannot reliably connect.
Solution
- Inspect the back of the display for the WiFi antenna. Verify it is present and screwed firmly onto the SMA connector.
- If the antenna is missing or damaged, a replacement 2.4 GHz SMA antenna is compatible. Search for a universal 2.4 GHz 7dBi SMA interface antenna as a replacement.
- After reattaching the antenna, retry WiFi setup (see Section 1 or Section 2).
Note: A longer replacement antenna may provide improved range.
7. Configuring WiFi from a Windows PC (USB Method)
Symptom
You do not have a smartphone or prefer to configure WiFi credentials from a Windows computer.
Cause
The mobile app is the primary setup method, but a PC-based USB configuration utility is also available as a backup.
Solution
- Download the WiFi Config PC utility from:
https://microframecorp.com/download-software
(Direct download: WiFi\_Config\_WIN.zip)
- Connect your Windows PC to the display using a USB A-to-B cable (the same type as a printer cable — flat on one end, square on the other). One ships with every display.
- Run the utility and enter your WiFi network name (SSID) and password.
- Save the settings. The display will attempt to connect to the specified network.
Note: The PC utility sets WiFi credentials only. Full display control is done through the mobile app.
8. Multiple Displays — Syncing and Control
Symptom
Multiple displays do not all respond to the app at the same time, or there is confusion about how displays sync with each other.
Cause
Displays do not communicate directly with each other. They each respond independently to commands from the app. If a display does not respond, it may still be in SoftAP mode rather than connected to your WiFi network.
Solution
- Each display must be individually joined to the same WiFi network as the device running the app (see Section 1).
- Once all displays are on the same network, all displays respond simultaneously to commands sent from the app — there is no need to control them one at a time.
- If displays appear to be out of sync or unresponsive, verify each display is on the local WiFi network and not still broadcasting a SoftAP setup network.
- Only one app instance should be controlling the displays. Multiple phones/tablets running the app simultaneously may cause conflicting commands.
9. App Communication Bug (App Version Issue)
Symptom
App suddenly stops communicating with displays after an app update, or app behaves unexpectedly across multiple users.
Cause
On rare occasions, an app release may contain a bug affecting display communication.
Solution
- Check for an app update in the Apple App Store or Google Play Store.
- Install the latest version of the D6500 app and retest.
- If problems persist after updating, see Section 3 (rediscovering the display by IP) and Section 5 (connection drops).
10. Display Firmware — Time Sync Not Working
Symptom
The app controls the display correctly (timers, settings), but the display will not sync time with the phone.
Cause
Certain older firmware versions have a known bug that prevents time synchronization.
Solution
- Check the display's firmware version by pressing the button on the back of the display twice. The firmware version will appear on the display face.
- If the firmware version is 311 or earlier, the display requires a firmware update to resolve the time sync issue.
- Contact Microframe support to arrange a return for firmware update (see When to Contact Support below).
When to Contact Support
Contact Microframe technical support if:
- You have completed a factory reset and WiFi setup but the display still will not connect.
- You receive persistent "Err save settings" errors that are not resolved by switching to a non-isolated network.
- The display's WiFi antenna is confirmed present and connected but the range is extremely poor.
- Your display firmware requires an update (version 311 or earlier with time sync issues).
- You need remote support via USB connection and AnyDesk — have the following ready:
- A Windows laptop
- A USB A-to-B (printer-style) cable (included with your display)
- AnyDesk remote support client, available free at anydesk.com
- You need to add an external output driver (chime/horn output) to your display — this is a factory modification.
