Easy fix for WIDI App and Firmware Update

How to update WIDI firmware via WIDI app?

Updating the WIDI firmware is a simple step-by-step process. The procedure is performed via the WIDI app for iOS or Android.

Please note that you can only update one WIDI device at a time. If you own multiple WIDI devices, make sure to power only one of them to avoid automatic pairing between WIDI devices.

In some cases, the architecture of your smart device can cause Bluetooth cache problems. This can cause errors, especially when updating multiple WIDI devices in succession in a single session.

Unfortunately, we can't change the way Android and iOS are designed. What we can do is provide you with a straight forward solution to solve the problem and improve your experience for the future.

Just follow these simple guidelines for the best experience.

Step 2: Check the instruction video:


Step 3: Use the manual for WIDI app (page 6):

Step 4: Easily troubleshoot Bluetooth cache issues:

Issue 1: If your WIDI App cannot connect to your WIDI device to start the updating process
Solution 1: Clear the Bluetooth cache as shown in the video below and try again.


Issue 2: If your update process failed and your WIDI device shows the GREEN LED
Solution 2: Clear the Bluetooth cache as shown above. Next, use WIDI App to re-connect to your WIDI device and select the correct product model to restart the updating proces.

Step 5: After updating, do a factory reset of your WIDI device. Clear your mobile device's Bluetooth cache and start a new connection.

  • Right, the updated app on my Android phone says “WIDI product is discovering services” but it has been a long time now and the WIDI Jack light is solid green so I guess it has failed? I try your suggestions: reset bluetooth on phone, reload Android WIDI app, now it says “WIDI Updater” instead of the name I gave the WIDI Jack. I reset both my phone and the WIDI Jack, same thing always says “The firmware is being updated…” Now my WIDI Jack is useless.

      Sorry to hear this James.If your update process failed and your WIDI device shows the GREEN LED, use WIDI App to connect to your WIDI device again and select the correct product model to restart the updating proces.

      If your device is named “WIDI Updater”, you should be able to resume updating the firmware.

      If you cannot, please delete all WIDI connections from your general Bluetooth list and turn Bluetooth off and on. It is essential you delete all previous connections to fully execute clearing your Android Bluetooth cache.


      If this still does not work, try a hard reset of your WIDI device.

      When the WIDI Jack is NOT powered on, press and hold the
      button. Power on the WIDI Jack until the green LED light
      flashes slowly for 3 times. Then release the button. The
      interface will manually reset to the factory default

    The app displays it is updating the firmware, but 30 minutes seems a bit long to me. The WIDI master LED is green. I tried on another WIDI Master, and now I have 2 WIDI masters with green LED’s and not working as expected. Using a conventional MIDI cable from my midi keyboard to a MIDI expansion works. Plugging in the WIDI masters in both devices (to basically act like the cable that worked), does not work.

    I find this very disapointing

      I am sorry to hear this. Updating takes 1 or 2 minutes. Did you follow the advise as shown in this blog? Like clear the Bluetooth cache of your mobile device?
