Here, we detail the firmware update procedure for the Sony XB43. This routine can take ten (10) to fifteen (15) minutes depending on the speed of your internet connection, source device used to update the speaker, distance between speaker and that device, Etc. Plus, you cannot roll back the update once you install it. That is, you’ll be unable to return to the prior firmware version after you finish this upgrade. So, be sure that you indeed want the update, and have thought through all ramifications before proceeding.
Sony XB43 Firmware Update: Preparations
You’ll need the following items:
-
- High speed internet connection,
- Bluetooth enabled mobile device,
- The Sony Music Center app that runs on said mobile device,
- the Sony XB43 BT speaker you’re updating.
- Compatible power adapters and charge cables for your speaker and mobile device.
Sony XB43 Firmware Update: Summary
Next, do the following to update the speaker. In short…
-
- Connect your mobile device to the internet. We suggest using WiFi for this work, and not your cellular connection.
- Install the Sony Music Center app if you haven’t already.
- Then, plug your XB43 and your mobile device to AC power. Why? Because we don’t want either of their batteries going dead while updating the firmware. In fact, a low battery could leave a corrupted version of the firmware in the speaker’s memory. This could, and probably would in all likelihood, brick the speaker. This would then likely render the unit useless and non repairable. So once again, connect the speaker to power before proceeding. Please !
- Disconnect any other Bluetooth speakers and devices from your mobile device for this process.
- Then, power up your speaker and mobile device, if not already running.
- Next, pair your mobile device with the XB43.
- Run the Sony Music Center app. The app should then find your speaker and display the home screen for the XB43, showing that a firmware update is available.
- Follow the on-screen instructions for firmware updating.
Sony XB43 Firmware Update: Step by Step Details
1. Connect the XB43 and your Mobile Device to AC Power
We connected ours to an AC outlet using a common USB power supply, as well as a common micro USB to USB-A cable. E.g. See this in the next picture.
You’ll know that the speaker is receiving external power if you see the charging light glowing orange.
2. Pair this Bluetooth Speaker with your Mobile Device
Connect the speaker to your phone / tablet where you will run the update. Here’s an example screenshot of the XB43 connected to an iPad.
Now keep both the speaker and your mobile device powered up and close to each other throughout the update, lest the update fail and result in a malfunctioning speaker.
3. Find the Sony Music Center App on your Mobile Device
We made a folder for all of Bluetooth speaker apps and put the Sony Music Center app in there on our test iPad, as you see in the next picture.
4. Run the Sony Music Center App to Continue with the Sony XB43 Firmware Update
As the app runs, it scans the host device running it for compatible Sony speakers. Wo, the app needs a brief period to find the XB43. But eventually, it does so, and displays its status screen, as we show next.
If the speaker does not appear in the app after thirty seconds or so, move it closer to your mobile device. Next, close the Music Center app, and then run it again.
Note the tan bar on the XB43’s home screen. This appears only when a firmware update is available for this speaker.
Note that if there are no firmware updates pending for the XB43, then you will see no brown bar. This situation we show in the next picture.
5. Tap the More Info Button Inside the Brown Update Bar
Tapping the More Info button brings up the Software Information screen, as follows.
6. Tap the OK Button
Tapping the OK button may bring up the following screen if you haven’t followed the above directions, and plugged your speaker into external power.
In fact, we suggest that you fully charge both speaker and the smart device before proceeding with this update. Doing so protects your XB 43 from a corrupt firmware upload in the event of a longer power outage, where the batteries could go dead before firmware updating is complete. Also, as a further precaution, once you fully recharge both devices, please leave both of them connected to external power until the update finishes.
Once speaker and smart device are charged, tap the OK button on the Connect Speaker to Power Supply window. That should then take you back to the previous page once again, as follows.
Or, if you quit the app, go ahead and restart it and repeat the above steps. This time, you should not get the Connect Speaker to Power Supply page. But instead, you will see the Software Information page that we see in the last picture.
7. Sony XB43 Firmware Update Begins
The updating then starts, as we show in the following screenshots. The Music Center app first downloads the new firmware package.
Once the app downloads the package, it unpacks and transfers it to the XB43 as the next pictures show.
Additionally, during the transfer to the speaker, the Power lamp on it pulses in groups of four pulses then a pause. E.g. Pulse-pulse-pulse-pulse-pause, pulse-pulse-pulse-pulse-pause,… During this time, all other lamps on the speaker are OFF.
7a. The Firmware Update Continues at Thirty Percent Complete
Now as shown in these screenshots, the Sony Music Center app displays a progress line, that gradually gets more brown as the firmware updating proceeds.
7b. The Sony XB43 Firmware Update is Now at Seventy Percent Complete
Now we’re probably about five minutes into the update. Indeed this process takes a relatively short time as compared to some of the other speaker models we’ve tested.
7c. Now at Ninety-Nine Percent Done
The next screen shows that the firmware transfer and update to the speaker have almost finished (99 percent done). E.g. The progress bar is practically all brown now.
7d. Firmware Install on the XB43 Begins
Now that the firmware has been transferred from your device to the speaker, the update process on the XB43 begins when you see this page.
7e Tap the OK Button
Touching the OK button takes you to the Speaker & Group page, where you see a list of previously connected speakers that the app knows about. Note that all are grayed out. So none are connected to the app during the xb43 update process.
8. Wait for the Sony XB43 to Shut OFF
While the speaker updates itself, its Power lamp flashes green.
Then after a minute or two, once the 43 finishes updating, the Power light goes dark. No more blinking.
9. Press the Power Button To Boot the XB43 Again
Press the Power button to turn this Bluetooth speaker on again, as pictured next.
The XB43 should again pair with your mobile device where you’re running the Sony Music Center app. The Power button turns solid green, and the Pairing button also glows steadily blue once the speaker has again linked to your mobile device.
Now after the XB43 reconnects to your smart device, the Sony Music Center app discovers that your speaker has come back online, and thus, displays an update-complete message, as follows.
10. Press the OK Button Back in the Sony Music Center App
With your speaker successfully paired to the app again, press the OK button, as shown in the last screenshot.
The app then displays the Sony XB43 home screen once again. But this time, note that there’s no longer the brown bar, as we see next. This means that the updating of the firmware worked, and that the speaker is now running the current firmware version.
11. Done with Sony XB43 Firmware Update !
You’re now finished updating the firmware to the current version in your Sony XB43 BT speaker. Enjoy the new features.
