Disconnected Blox Troubleshooting

If your FxBlox appears disconnected or is not responding properly, you can diagnose the issue by checking the LED color patterns. Follow the appropriate troubleshooting steps based on what you observe.

Step 1: Check LED Color Status

First, observe your FxBlox LED to determine its current state:

Scenario 1: Continuously Flashing Cyan LED

What it means: Your FxBlox needs to be set up from scratch.

Solution:

1. Open the FxBlox app at https://docs.fx.land/fxblox-web/ in Chrome or Edge
2. On the Set identity screen, use Clear app storage — this is the browser equivalent of uninstalling and reinstalling, and removes the stored identity, Blox list, settings and caches
3. Follow the setup process from the start
4. Set up your FxBlox from the beginning as if it were a new device

See FxBlox App Setup for the full walkthrough.

info

A continuously flashing cyan LED indicates the device is in setup mode and ready for initial configuration.

Scenario 2: LED is Off

What to do: Test the firmware status with a power cycle.

Steps:

1. Unplug your FxBlox from power
2. Plug it back in and observe the LED sequence
3. Check the LED pattern:
   • If you see: Blue → Green → Off → Yellowish → Off
   • This means your FxBlox is on the latest firmware

If on latest firmware, perform factory reset:

1. After confirming the firmware sequence (blue → green → off → yellow → off)
2. Unplug and replug the device 4 times
   • Each time, wait for the sequence: yellow → off
   • Then unplug and plug back in
3. On the 4th replug (5th total including the initial test):
   • The LED will turn yellow, then immediately purple
4. Wait 10 minutes while it processes
5. After 10 minutes, it will start flashing cyan
6. Clear app storage in the web app (on the Set identity screen)
7. Set up from the beginning

warning

Make sure to wait for the complete yellow → off sequence before each unplug/replug cycle. Timing is important for this reset process.

Scenario 3: Bluetooth Connection Method

If the above methods don't work, try connecting via Bluetooth:

Steps:

1. Open the FxBlox app at https://docs.fx.land/fxblox-web/ in Chrome or Edge
2. Go to Settings → Bluetooth (/settings/bluetooth)
3. Click the connect icon in the top right corner, then pick the device starting with fulatower or fxblox in Chrome's chooser
   • The Blox advertises periodically — leave the chooser open for up to 90 seconds if it does not appear straight away
4. If connection succeeds, you'll see several command buttons appear
5. Click "Hotspot" to put your Blox into hotspot mode
6. Connect your computer or phone to the "FxBlox" WiFi network
7. In the app, open the connection options next to "Disconnected"
8. Click "Connect to WiFi"
9. Follow the on-screen instructions to reconnect your Blox to WiFi

tip

The Bluetooth connection method is useful when your Blox can't connect to WiFi but is still responsive via Bluetooth.

Scenario 4: Re-imaging Required

If none of the above solutions work, you may need to re-image your FxBlox:

For RK1 Model (most common):

• Follow the guide: FxBlox Hardware RK1 Re-imaging

For Raspberry Pi Model:

• Follow the guide: FxBlox Hardware RPi Re-imaging

info

Most FxBlox devices are RK1 models. If you're unsure which model you have, try the RK1 re-imaging process first.

LED Color Reference

LED Pattern	Meaning	Action Required
Continuously flashing cyan	Setup mode	Clear app storage and set up from scratch
Blue → Green → Off → Yellow → Off	Latest firmware detected	Perform 4x unplug/replug reset
Yellow → Purple	Factory reset in progress	Wait 10 minutes
Flashing cyan (after reset)	Ready for setup	Clear app storage and set up
Off/No response	Possible hardware issue	Try Bluetooth method or re-imaging
