SugarPixel is configured using the SugarPixel Hub app (iPhone / Android). It connects to SugarPixel via Bluetooth for setup only — once configured, SugarPixel runs completely independently.
1Install the App and Review the Basics
Download and install the app, allow all permissions including notifications (required for firmware update alerts), then read the following before connecting:
- The app does not connect to your CGM and does not need to be on the same phone as your CGM app.
- Multiple phones can configure the same SugarPixel. One phone can also manage multiple SugarPixels — each appears as a separate device and is configured independently.
- All settings are saved on the SugarPixel, not in the app.
- The app is not meant to stay connected. Always tap Disconnect in the app menu when you finish making changes. Leaving it connected can interfere with WiFi downloads and may require a reboot to reconnect.
Do not connect using your phone's system Bluetooth settings. Always connect from within the SugarPixel Hub app.
2Connect to Your SugarPixel
When the app opens, it automatically scans for nearby SugarPixels. Your device will appear in a list — each SugarPixel has a unique name (for example: SugarPixel-2A28).
Tap directly on your SugarPixel's name in the list to begin configuration.
If no devices appear, tap Scan Again. If your SugarPixel still doesn't show up, move closer to the device, unplug and replug it to reboot, then scan again. If the scan shows "Stopped", make sure Bluetooth is enabled and all app permissions are allowed.
If you continue to have connection issues, see the Bluetooth troubleshooting section below.
3Enter the Pairing Code
The first time you connect from a new phone, your phone will show a Bluetooth pairing prompt asking for a PIN code.
At the same moment, your SugarPixel's physical screen will display a unique 6-digit code. You must look at the SugarPixel display and type that exact code into your phone's prompt.
Do not enter example codes suggested by your phone (such as 0000 or 1234). The code must be the exact 6-digit number shown on the SugarPixel screen — it is unique every time you pair a new phone.

App Will Not Connect (Bluetooth)
Step-by-step fixes when the app can't find or pair with your SugarPixel
If the SugarPixel app cannot connect, follow the steps below in order.
1Restart Both Devices
- Reboot your phone
- Unplug SugarPixel and plug it back in
- Try connecting again in the app
If you previously forgot to tap Disconnect in the app, this often resolves the issue.
2Check App Permissions
Open your phone's Settings → Apps → SugarPixel and confirm all permissions are allowed. Then reopen the app and try connecting again.
If the app shows "Stopped", also ensure Bluetooth is enabled on your phone.
3Remove and Re-Pair Bluetooth
An incorrect secure pairing code is the most common cause of connection failure.
SugarPixel displays a unique 6-digit pairing code on its screen when pairing. If the wrong code was entered, your phone may show "connected," but SugarPixel will not send data.
To fix:
- Open your phone's Bluetooth settings
- Find the saved SugarPixel device
- Select Unpair / Forget / Delete
- Restart your phone
- Unplug and replug SugarPixel
- Open the SugarPixel app and reconnect
- When prompted, enter the 6-digit code shown on the SugarPixel display
4Manual Pairing (If Needed)
If the app still cannot connect:
- Remove any saved SugarPixel in Bluetooth settings
- Restart phone and SugarPixel
- In phone Bluetooth settings, tap SugarPixel when it appears
- Enter the 6-digit pairing code
- If it shows "Connected," tap to Disconnect (do not forget)
- Reboot SugarPixel
- Open the SugarPixel app and connect
5If You're Prompted for Pairing Every Time
If you must repeat pairing steps or enter the code every time, the Bluetooth storage may be full.
To reset:
- Connect to SugarPixel in the app
- Go to Menu → Reset → Reset Bluetooth
- On your phone, remove the saved SugarPixel device
- Repeat pairing from the app using the 6-digit code
If multiple phones have connected before, remove SugarPixel from Bluetooth settings on each device.
SugarPixel Not Shown in the App
Device isn't appearing in the app — common causes and how to fix each one
If the app is not connecting, it is usually caused by one of the issues below.
1Previously Connected, But No Longer Shows in the App
Most commonly, the Disconnect button was not tapped after the last configuration session. The app is not designed to stay connected continuously.
To fix:
- Unplug SugarPixel.
- Plug it back in to reboot.
- Open the app and reconnect.
Going forward, always tap Disconnect when finished editing settings.
2SugarPixel Purchased Before September 2022
The mobile app–compatible firmware was released in September 2022. If your SugarPixel has never been updated since then, it must be updated before it can work with the app.
How to check:
- Restart SugarPixel.
- If the display shows "CONFIG" during boot, it is running outdated software.
Follow the SD card update instructions to update the firmware.
3Display Shows "Run Hardware Test"
A step was skipped during initial setup. Follow all setup instructions to resolve.
4If the App Shows "Stopped"
- Bluetooth is turned off on your phone, and/or
- The SugarPixel app does not have required permissions enabled
Open your phone's Settings → Bluetooth and confirm it is on. Then check that all permissions for the SugarPixel app are allowed.
