Firmware Update

How to update Vimo Swim firmware via Bluetooth OTA.
Keep your Vimo Swim up to date to enjoy the latest features and improvements.

Before You Start

  • Ensure device battery is at least 50% charged
  • Keep your phone close to the device (within 1 meter)
  • Do not power off or use the device during update
  • Ensure stable Bluetooth connection

Update Process

Step 1: Scan Your Device's QR Code

  1. Open the Vimo Connect app on your phone
  2. Flip your Vimo Swim over. There is a QR code on the back of the device
  3. Scan it with the app: it identifies your unit and fetches the matching firmware automatically
Received a firmware file directly from the team? You can also load a .zip firmware package from your phone's storage instead of scanning the QR code.

Step 2: Start the Update

  1. Confirm the update in the app
  2. The device will show "Updating" and "Do not power off" on the display
  3. Wait for the update to complete (2-3 minutes)
Do not power off the device during the update! Wait until you see the normal home screen.

Step 3: Verify Update

  1. Device will restart automatically after update
  2. Check the firmware version on the device's boot screen or at Device → Info

DFU Mode (Device Firmware Update)

When updating, the device enters a special DFU Mode:

  • Display shows "Updating" with "Do not power off"
  • Device advertises as "DfuTarg" over Bluetooth
  • Normal operation is suspended during update

DFU Mode Timeout

If no update is received within 2 minutes, the device will automatically exit DFU mode and restart normally.

This safety feature ensures your device won't get stuck if:

  • Bluetooth connection is lost
  • Update is cancelled
  • Phone goes out of range
