Once you have the app installed, please follow along with written directions below to connect your DynaFlex II Go device.

LED 1 (Left side) will remain solid green and LED 4 (Right Side) will begin blinking when the device is in pairing mode.
Open the MTUSDK Omni App and tap the blue Select Device button at the top of the screen of the screen.
On the next screen, make sure Bluetooth LE is selected under the Connection Type setting. You should see a device code appear on the screen.

Once you have confirmed it’s the right device, tap the device.
Next you’ll see a screen appear titled “Bluetooth Pairing Request“. You’ll want to enter 6 zeros (000000) as the pairing code and then tap Pair.

To disconnect the device, tap this icon and the icon will change to a plug sign next to a plug.
