Updated over 2 weeks ago

Bluetooth pairing issues between your Fieldy device and an Android phone can often be resolved with systematic troubleshooting. This guide provides step-by-step instructions to help you address common connectivity problems.

This article is for Android devices. If you're using iOS, visit this guide.

Before diving into specific solutions, try these general troubleshooting steps to address pairing issues:

  1. Close the Fieldy App: Fully close the app to ensure no background processes interfere with pairing.

  2. Power Off the Fieldy Device: Turn off the device completely.

  3. Restart Your Android Phone: Restarting the phone can clear temporary glitches.

  4. Reopen the Fieldy App: After restarting, open the app and attempt to pair the device again.

If the app finds your device but fails to connect to it with this error, you're most likely experiencing Bluetooth Pairing Issues.

Fieldy devices use LED lights to indicate their status:

  • Flashing Blue Light: The device is ready to pair.

  • Solid White Light: The reset process was not completed successfully, and the device still holds old pairing data. Ensure the device shows a flashing blue light before attempting to pair or unpair it. If the light is solid white, follow the reset instructions below.

Old or conflicting Bluetooth pairings can prevent successful connections. To clear these pairings:

  1. Open the Settings menu on your Android phone.

  2. Tap Connections (or Bluetooth & device connections, depending on your device).

  3. Select Bluetooth.

  4. In the list of paired devices, tap the gear icon next to each relevant device.

  5. Tap Unpair or Forget for the devices you want to remove.

  6. Restart both your phone and the Fieldy device. After clearing old pairings, try pairing again from the Fieldy app.

  7. Turn off the old Fieldy device after forgetting it to ensure it does not interfere with the new pairing process.

What to do?

First: Unpair the Fieldy device

Unpairing via the Fieldy App

To unpair a Fieldy device using the app:

  • Open the Fieldy app and navigate to the device’s settings page.

  • Tap Forget This Device.

  • When prompted about the device’s LED state, select Pulsing Blue (not White).

  • The app will forget the device, allowing you to pair a new one. Note: A factory reset does not automatically unpair the device from the app. Ensure the device is in pulsing blue mode before confirming in the app.

Be careful, this will erase your Offline Storage. Short click, then immediately press and hold the Fieldy button for 10 seconds until 4 different colors blink. Then the light should switch to Blue. If it comes back to White instead of Blue, do it again.Timing is critical: The long press must begin very quickly after the first click. If the delay is too long, the reset will not register, and the device may continue showing a solid white light.


Exact steps

  • Short Click (up to 1 second, should not turn off/on the device)

  • Gap (very short, about 0.5 second)

  • Press and Hold for 10 seconds

  • Light should cycle in 4 colors.

  • Light should become Blue.- If the light remains White, repeat the process ensuring the timing between the short click and long press is immediate.

If it always come back to White, then most likely Short Click was not captured. If you still struggle, we recommend to send a video of you doing it to our Customer Support, they will let you know what you're doing wrong.

Then: Force Stop the App

  1. Go to Phone settings

  2. Find "Apps", press on it

  3. Find "Fieldy" in the app list, press on it

  4. Press "Force stop."

Finally: Connect and Pair
