Bluetooth problems

[John White]

It appears that many people, me included, are having bluetooth connections dropping. Are the Wunderlinq engineers working on a solution?

Hi John,

Yours is the first report that we are aware of. The only known connectivity issues we are aware of are that some Samsung devices aren't reconnecting automatically. 

Please reach out to support so we can work with you.

Thanks,

Keith

Hello,

Until yesterday, I thought I was the only one having this problem. When I turn on the ignition, no connection is established between WLQ and the A53. When I select WLQ on the A53 under Bluetooth, the connection is established and I can operate WLQ on the A53 with the left handle. The Bluetooth connection remains active until I start the engine. When I start the engine, the connection is lost and is not reestablished. When I then select WLQ under Bluetooth on the A53, the connection is re-established and remains stable. However, when I stop the engine and start it again, the connection is lost and must be re-established manually.

I noticed that the battery voltage, with the engine not running, is 11.9 volts and is displayed in YELLOW on the WLQ. When the engine is running, I have around 14.X volts. I connected a battery charger and fully charged my battery. When I turned on the ignition again, I had to manually start the connection between WLQ and the A53, but the connection remained when I started the engine. Only when I started the engine again (or the next time, unfortunately I didn't pay attention) did the connection end and had to be restarted manually. Could it be that WLQ has a problem with low voltage?

Due to a lack of alternatives, I have come to terms with the problem and, in conjunction with an A53 and Kurviger.DE, this is still the best solution for me.

Should I also post this text at https://blackboxembedded.com/pages/contact-us?chat or is it sufficient to send an email to SUPPORT?

Kind regards

Hi,

After the last update of the wunderlinq app, I had exactly the same problems on my S1000Xr. The bluetooth connection kept dropping out and wouldn't reconnect. The problem only occurred after the last update. The update was the worst ever!
I then downloaded version 2.90 from github as an apk and installed it. After that all problems were gone and it works fine again. I can only recommend everyone to try the latest version of githup and not from the Playstore.

Hello,
I'm a little confused. I have app version 2.90 with firmware 2.1 on my A53 and my TAB S9. I can find version 2.90 on GitHub. What's the difference?
And please don't be angry, but I don't download APK files from sources I don't know. And I don't have the knowledge to judge whether GitHub and the APK are really from Wunderlinq.

I am experiencing the same on iphone IOS 18.5.  Version App 2.0.22(2), firmware 2.1

The Wunderlinq guys sent me a new unit, but my problems persist. This is the first I've heard of the new version of software. I'll probably give it a try. At this point it can't hurt to try.

So has there been a resolution to this problem? My unit was working great until the last couple weeks, now if it will connect to bluetooth it will one keep connection for a few seconds at a time till it finally just stops.

[Ich Bins]

Is there any news here yet? I've been having massive problems with my Wunderlinq and the Bluetooth connection for some time now. When I switch the bike off and then on again, Wunderlinq no longer connects automatically via Bluetooth. I first have to go to the Bluetooth settings on my cell phone and or tap Wunderlinq manually, then the Wunderlinq connects again. This is very annoying.

I had a similar problem with mine. First off, my gps mount on the bike was dead, after replacement everything started working much better. When restarting after shutting the engine off I hit the Bluetooth icon at the top left of the grid screen and it usually reconnect right off.

[Ich Bins]

Until a few months ago, the Wunderlinq would always connect automatically.

Now, however, I always have to start the connection manually after restarting the bike. That can't be right!

I can also start the connection manually by pressing the Bluetooth symbol several times on the Wunderlinq app home page. But I have to press it three or four times.

@Jeremie Sloan

What type of phone do you have, and which version of Android is it running?

I have a Samsung S22+ with the latest version of One UI, 7. It still worked last year with One UI 6. However, I don't know if the issue is really due to the update to One UI 7.

One thing that has helped me was to install the latest version of the software, but not from the Play Store. I went to the Wunderlinq site and downloaded the new version. I think the developers need to update the software in the Play Store, or at least let everyone know about it.

I downloaded and installed version 2.95 of the app from GitHub. However, the problems remain.

@Keith 

Can you help us?

[Jeremie Sloan]

I'm using an A7 lite tablet with current software. I've always had issues reconnecting after shutting the engine off and restarting.

[MW]

I'm betting it's a software issue. The developers replaced my hardware and the problem continued until I installed the new version of software. I have only tested it on one ride of about 300 miles. A multi day ride might be different maybe.

[Ich Bins]

If it really is a software problem, it's pity that the developers aren't even speaking up here.

It worked perfectly last year, so why doesn't it work now?

I from France, 

I meet this problem with my Samsung A34 5G with UI 6.1 and android 14. At the beginning I thought that my problem was the battery of my RT1250 of 2019 but since I changed it the problem remains :(

As a lot of you , I must forced bluetooth connexion and some time I must restart my smartphone.

This problem is really painful.

My point of view is in relation with the voltage level and perhaps our black box isn't stable whan the voltage is too low when you restart your motorbike.

As you I hope one solution software or hardware from Keith

I am currently very disappointed with the level of support I have received from Support team and Keith. A few days ago, I contacted the support team directly via the homepage to ask for an explanation of the problem. Unfortunately, I have not yet received a reply. There has also been no response from the support team in this forum.

Is there already experience with alternatives to Wunderlinqq

[Toni Bärk]

I'm a fan of WunderLINQ, but if there's still no new information about the problem after seven weeks, I'll take a closer look at the Carpuride W702BS.
