Update Firmware

How to Update Firmware

Step 1: Updating ring firmware requires an iOS device and the Senstream app.

If installing the app for the first time we recommend reviewing the iOS app getting started documentation.

Step 2: Open Record a Session screen using a variety of options in the app.

Local Files Browser mode

Senstream Cloud mode

Step 3: Find the ring or pair it if it's not connected.

If new firmware is available an indicator will show. Tap on the ring to see the Ring Details.

Step 4: Find Firmware in Ring Details and tap “Upgrade firmware”

Step 5: View available firmware and select the latest to update.

Note: It is possible to change the firmware to any version. After selecting the firmware version, the list will close and return to the Ring Detail screen where a progress bar will show the firmware loading onto the ring.

The firmware is now updated
