Using the Tibbo Updater Smartphone App

There are three ways of accessing .TCU files from the Tibbo Updater app (available on iOS and Android):

  • You can select one of Tibbo's officially released .TCU files (it is not possible to access your own .TCU files in this manner).
  • You can open a .TCU file that you previously saved on your device or in iCloud or Dropbox.
  • You can "copy" (export, share) a .TCU file to the Tibbo Updater app from some other app that has this file. For example, you can email a .TCU file as an attachment and open this email in the email client app on your iOS/Android device. You can then "copy" the attached file to the Tibbo Updater app.
  • Make sure your Tibbo device is not connected to the network — this will allow it to enter the Bluetooth Low Energy (BLE) update mode.
    • For Tibbo devices with an Ethernet port, this is as easy as making sure that the Ethernet cable is not plugged in.
    • For the WM2000, you need to prevent the device's association with an access point. To achieve this:
      • Power down your access point(s) or move the WM2000 out of your Wi-Fi network's range.
      • Alternatively, you can set the autoconnect parameter of the Device Configuration Block (DCB) to no. This can be done either via the BLE console or the Companion App that ships preloaded on WM2000 modules. Note that the WM2000 ships with autoconnect set to no.
  • The M/L flowchart shows how to place your device in the update mode's BLE Phase. Alternatively, follow this step-by-step infographic:


On the WM2000, you can skip the wait by pressing and releasing the MD button before the device associates with an access point.

  • The following illustrates the update procedure using an iOS device when you are "copying" the file from another app.
    • In that other app (such as an email client), tap on the .TCU file and tap Copy) — you will be presented with exporting choices.
  • Select the Tibbo Updater app (note that the app's icon could be "beyond the screen edge" and you may need to scroll through the list to get to it).
  • Once you tap on the Tibbo Updater app's icon, you will be "teleported" into the Tibbo Updater app. The app will display a list of discovered Tibbo devices. Only the devices that are in the BLE update mode will appear on the list. If you followed the steps above, your Tibbo device should appear on the list.
  • Tap the target device to start the upload.
  • The app will start sending the file to the selected device. During the upload, keep your iOS device as close to the target Tibbo device as possible.
  • When the file upload completes, your Tibbo device will perform the internal copying of the received data. The green and red status LEDs will be solid on during the copying. This is the "critical section" of the entire procedure.
    Do not disconnect the power or reset your Tibbo device while the file is uploading or in the "critical section" of the update procedure. Doing so may brick the hardware!
  • Once the update completes, your Tibbo device will reboot automatically.
