EUC world loses Bluetooth connection at random

[Z-Rabbit]

So this has happened a few times: I'll be riding along (on my V12 HT), nothing special is happening, my music is blasting from the Bluetooth speakers, and suddenly I start hearing beeps every 10 seconds or so. I look at my phone, and EUC world has lost Bluetooth connection. Furthermore, it doesn't show up in the list of available connections after it drops.

I know that if I stop, turn off my wheel, and wait 30 seconds before booting it back on, the connection shows up again. But I'm just wondering if anyone else has had this issue. It seems to me to be a problem with the wheel rather than EUC world, but regardless, it's happening about every other ride I go on.

Any ideas?

I don't know what kind of phone you have. But many cheap phones don't have good bluetooth connections. That's why you lose your connection. I've tried numerous watches for riding EUC over the years. Samsung, garmin, Unihertz Jelly 2...none of which was satisfactory to use. I finally  got the Motorola Razr. Wow, no more issues with watch faces too small, too hard to see, bluetooth connection breaking off, hard to upload or download. If you are still searching for a great watch for riding, try Motorola Razr+, high recommended! People always asks me "What's that on your wrist?"  Actually, it is a phone and a watch, flip it!

I wanted to update: I still have the same issue, although I have a better idea how to fix it, at least temporarily.

After booting up EUC world, it automatically connects to my V12 HT. Then (typically in the next minute or 2) it will start doing the "lost connection" beep. I turn my phone's  bluetooth off and back on, then it's fine, typically for the rest of the ride.

It's not specific to any one phone, I have a completely different phone now from when I first reported the issue, but it's still there. I suspect there's something between EUC world and the V12 that aren't playing nice, but I don't know anything about programming/bluetooth protocol/etc.

Funnily enough since the last 2 android updates for my phone I sometimes find myself looking down at EUC World to see it has lost my connection to the wheel, and I'm on a Master, which previously has had flawless connectivity with that app since I've had it. It has only happened a few times so far, so I turned on the heartbeat so I could hear when it dropped, and of course sods law dictates it hasn't done it once since.

Seems to be a common occurrence on the Lynx, happens to me all the time and I know more riders with the same problem, problem is not on the phone or EUC World, restarting the wheel fixes it.

Interesting... for me, I haven't had a single dropout since I got my Lynx 3 weeks ago. With my V12, I've had it happen so often that I have the fix down to a science.

For anyone who may stumble into this thread looking for a solution at some point in the future, here's what I've found works to restore the connection (YMMV, I am not a doctor, etc.):

-Turn off bluetooth, then turn it back on. With my V12, this works every time. It only takes a few seconds, and you don't have to get off your wheel to do it. (I should note that I haven't used my V12 more than a few minutes at a time since getting my Lynx, but I don't have any reason to assume this would have changed)

-If that doesn't work, turn the wheel off, wait 30+ seconds, then turn it back on.

-If THAT doesn't work, reset EUC world AND your wheel at the same time. You might also consider cycling bluetooth while doing this to cover all the bases.

-If you still don't have connection, you clearly have done something wrong in the eyes of the EUC gods and must repent for your sins by sending me EUC-related gear.

Sometimes rebooting/restarting the phone helps.

Just wanted to give an update: I've had the bluetooth dropouts happen a few times now over the past month or so with my lynx. It doesn't happen often, and just cycling the wheel fixes it. But I don't like knowing the possibility exists that I might miss an alarm because my connection could drop at random.

Is there any kind of error log function in the app?

Mine does it as well, what app do you use? EUC world has a wheel disconnect sound that you can enable which is very useful.

[Z-Rabbit]

I should have clarified, I'm using EUC world. I get the same disconnect sound, chimes about every 10 seconds or so. But I'm trying to figure out why it's disconnecting. Is it my wheel, phone, or EUC world?

[Robse]

Android 10 and up:

Control:

1: Turn of Adaptive battery

2: Battery Usage:  Give EUC world Unrestricted access to battery usage

Enable developer options:

1. Go to Settings > System.
2. Touch About phone.
3. Touch the Build number field xx times ( 12 times for Android 12 etc. ) You will begin seeing a message as you approach the xx touches.
4. Touch the back arrow once complete, and Developer options will now appear under Settings.

3: Developer Options;   Disable Bluetooth HCI snoop log

4: Developer Options; Bluetooth AVRCP Version: 1.5 (normal default)

5: Developer Options;  Select MAX numbers of connected Bluetooth audio devices; 5 ( select highest number)

As I already said, it's the Lynx, the Lynx does this.

I was just about to make a new topic on this problem, when I saw this thread, so I will write in here instead..

I have been having problems with EUC World losing connection to my wheel kinda randomly, but I think I have narrowed it down now. It seems to happen when I turn off another device connected to my phone via bluetooth. I got an Intercom system in my helmet for music and phonecalls and sometimes when I turn that off, EUC World will also lose the connection and then when I notice, I have to go into EUC World again and it will auto reconnect to my wheel, but the previous data on my route will be lost, so it will start a new tour recording.

I have a Pixel 6A phone and it seems to work fine with all my other bluetooth devices, so not sure why this happens.

That sounds like a problem with your phone, you can set EUC World to resume the tour so you don't need to start a new one.

[Jonah Hax]

It's already set to resume, but it will not record anything from when it loses connection and until I notice it..

But I will try with another phone and see if it still happens.

@Jonah Hax  Can you confirm that this is not a loss of the BT conn but the app shutting down? If so, I had the same problem with my previous intercom

I thought it was due to the MIUI build bc Seba didn't have this bug and couldn't see anything related in the crash log, when the intercom died the problem was solved with the new one (same phone, same ROM/version)

Not sure how to confirm that, maybe there is some kind of BT log on the phone? Anyway, I tested with another phone and it did the same thing. EUC World dropped the connection when I turned the Intercom off..

I got a third phone I will test also, but have to put my wheel back together first :-)

Connect everything as you normally do, keep your screen on with eucworld running
As you turn off your intercom look at the screen, does the green(brown if tour is recording) bottom status bar turn blue or gray? = No com/loss of the BT conn

 

Or does the app just shut down so your phone switch back to the home page?(mine did this)

I'd also tested another phone as well as soft reset, reinitialize BT com and intercom,  nothing worked so I was just used to turn off the intercom last after a ride
Then it get fixed when I changed the intercom for a new model
