| 1 | +# Disconnected Blox Troubleshooting |
| 2 | + |
| 3 | +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. |
| 4 | + |
| 5 | +## Step 1: Check LED Color Status |
| 6 | + |
| 7 | +First, observe your FxBlox LED to determine its current state: |
| 8 | + |
| 9 | +### Scenario 1: Continuously Flashing Cyan LED |
| 10 | + |
| 11 | +**What it means**: Your FxBlox needs to be set up from scratch. |
| 12 | + |
| 13 | +**Solution**: |
| 14 | +1. **Uninstall the FxBlox app** from your mobile device |
| 15 | +2. **Reinstall the FxBlox app** from your app store |
| 16 | +3. **Open the app** and follow the setup process |
| 17 | +4. **Set up your FxBlox from the beginning** as if it were a new device |
| 18 | + |
| 19 | +:::info |
| 20 | +A continuously flashing cyan LED indicates the device is in setup mode and ready for initial configuration. |
| 21 | +::: |
| 22 | + |
| 23 | +### Scenario 2: LED is Off |
| 24 | + |
| 25 | +**What to do**: Test the firmware status with a power cycle. |
| 26 | + |
| 27 | +**Steps**: |
| 28 | +1. **Unplug your FxBlox** from power |
| 29 | +2. **Plug it back in** and observe the LED sequence |
| 30 | +3. **Check the LED pattern**: |
| 31 | + - If you see: **Blue → Green → Off → Yellowish → Off** |
| 32 | + - This means your FxBlox is on the latest firmware |
| 33 | + |
| 34 | +**If on latest firmware, perform factory reset**: |
| 35 | +1. After confirming the firmware sequence (blue → green → off → yellow → off) |
| 36 | +2. **Unplug and replug the device 4 times** |
| 37 | + - Each time, wait for the sequence: yellow → off |
| 38 | + - Then unplug and plug back in |
| 39 | +3. **On the 4th replug** (5th total including the initial test): |
| 40 | + - The LED will turn yellow, then **immediately purple** |
| 41 | +4. **Wait 10 minutes** while it processes |
| 42 | +5. After 10 minutes, it will start **flashing cyan** |
| 43 | +6. **Uninstall and reinstall** the FxBlox app |
| 44 | +7. **Set up from the beginning** |
| 45 | + |
| 46 | +:::warning |
| 47 | +Make sure to wait for the complete yellow → off sequence before each unplug/replug cycle. Timing is important for this reset process. |
| 48 | +::: |
| 49 | + |
| 50 | +### Scenario 3: Bluetooth Connection Method |
| 51 | + |
| 52 | +If the above methods don't work, try connecting via Bluetooth: |
| 53 | + |
| 54 | +**Steps**: |
| 55 | +1. **Open the FxBlox app** |
| 56 | +2. **Go to Settings → Bluetooth Commands** |
| 57 | +3. **Click the connect icon** in the top right corner |
| 58 | +4. The app will attempt to connect via Bluetooth to your Blox |
| 59 | +5. **If connection succeeds**, you'll see several buttons appear |
| 60 | +6. **Click "Hotspot"** to put your Blox into hotspot mode |
| 61 | +7. **Connect your mobile phone** to the "FxBlox" WiFi network |
| 62 | +8. **In the app**, click the **down arrow next to "Disconnected"** |
| 63 | +9. **Click "Connect to WiFi"** |
| 64 | +10. **Follow the on-screen instructions** to reconnect your Blox to WiFi |
| 65 | + |
| 66 | +:::tip |
| 67 | +The Bluetooth connection method is useful when your Blox can't connect to WiFi but is still responsive via Bluetooth. |
| 68 | +::: |
| 69 | + |
| 70 | +### Scenario 4: Re-imaging Required |
| 71 | + |
| 72 | +If none of the above solutions work, you may need to re-image your FxBlox: |
| 73 | + |
| 74 | +**For RK1 Model** (most common): |
| 75 | +- Follow the guide: [FxBlox Hardware RK1 Re-imaging](../hardware/fxblox-hardware-rk1-reimage.md) |
| 76 | + |
| 77 | +**For Raspberry Pi Model**: |
| 78 | +- Follow the guide: [FxBlox Hardware RPi Re-imaging](../hardware/fxblox-hardware-rpi-reimage.md) |
| 79 | + |
| 80 | +:::info |
| 81 | +Most FxBlox devices are RK1 models. If you're unsure which model you have, try the RK1 re-imaging process first. |
