Errors & Troubleshooting

This section covers common issues that may occur when using the HealthyWear Flutter app, especially while connecting to BLE wearable devices like Sensoria Smart Socks.

App Crash When Connecting to Sensoria Sensors

Problem

The app crashes or fails to connect when trying to pair with a Sensoria sensor.

Cause

This is most likely due to a misconfigured or missing BLE protocol on the sensor. If the sensor is not broadcasting with the expected F20 streaming protocol, the app cannot initialize communication and may crash.

Solution: Reset Sensor to Factory Defaults (F20 Protocol)

You can use the LightBlue app to manually reconfigure the sensor.

Reconfigure Sensoria Sensor using LightBlue

  1. Launch LightBlue and connect to your sensor
    Look for a name like: Sensoria-C1-XXXX

  2. Locate BLE Control Points

    • Scroll down until you see:

      • Control Point RX

      • Control Point TX

  3. Start Listening for Notifications

    • Tap on Control Point RX

    • Select “Listen for notifications”

  4. Send the correct protocol

    • Tap on Control Point TX → Write new value

    • Enter this hex command:

      04-01-04-0F

    • Press Done

      This sets the default F20 protocol, which uses 3 analog sensors + 9-axis IMU.

Reboot the Sensor

To complete the reset:

  1. Tap Control Point TX again → Write new value

  2. Enter this hex value to reboot:

     01-05

  3. Press Done
    The sensor will now restart and should be discoverable by the app again.

After Reset

  • Restart the HealthyWear app

  • Try connecting to the sensor again

  • You should now be able to pair without issues

Bonus: Check BLE Status

Make sure your device has:

  • Bluetooth enabled

  • Location permission granted

  • Sensor is charged and within range
