Ring LED States

PreviousRing SensorsNextCharging and Power Management Basics

Last updated 1 year ago

The Senstream status LED has different meaning depending on whether it is on the charger or not.

Charging LED states

While connected to the provided charger cable the ring LED will display the current battery level using two colors.


Session LED states

Off the charger, the ring is reset and will automatically be placed in to pairing mode.

Ready to Pair

When removed from the charger, the ring's LED will flash blue indicating that it is advertising its bluetooth connection and ready to be paired.

Paired and Ready

When the ring has been successfully paired the LED indicator will turn a solid green.

EDA Streaming Data

LED indicator is a solid pink when the EDA path is live and actively streaming data. After the session is stopped the LED will revert to the "Paired and Ready" green state.

Not Receiving Data

When the ring is removed from the finger during an active session measuring EDA, the LED will flash pink indicating that it is looking for input.


Waking the Ring

After about 2 minutes of inactivity the ring will enter a sleep mode and shut down the LED. To wake the ring, simply tap the ring and the flashing LED will indicate the ring is now awake.


Unexpected LED States

Very rarely the Senstream ring may display unexpected LED states. In these cases it is recommended to reset the ring by placing the ring back onto the charger. Once the ring LED displays its indication of battery charge, it is reset and can be removed from the charge to continue use.


PPG Sensor

Note that the PPG sensor at the bottom of the ring is not an LED status indicator. The green light is part of the sensor's process to capture data.
