My fitbit blaze won't sync

[celiawheelia]

I have had my blaze for 2 weeks and have been very very happy but now it won't sync. When I try it says tracker not found. I haven't updated my phone software and it was working fine until this morning. If I delete the app and re pair my blaze,will I lose all my data? Am very disappointed

I tried that, it was ineffective.

They keep insisting the problem is solved, or will easily be solved by the method they have posted, which is simply not true.  I have an Android Galaxy 6.  I have been successful at getting it working again, although it is quite a pain. I will try to post what works for me on this thread in case it's helpful.

If your app is on your phone, and you delete that, when you reinstall it your information should still be there, although you will have to sign in with your password again to see it.  I believe this information is stored in the cloud, as you can access it from apps on your phone, computer, or on the internet (without using an app).

Doesn't work.

I have an Android Galaxy 6, here is what works for me:

1) Make sure watch is fully charged; 2) Uninstall fitbit app from phone (make sure you are not just deleting icon from home page), 3) if possible delete fitbit device from bluetooth (settings, bluetooth, gear symbol by device name), 4) turn off Bluetooth on phone, 5) turn phone off, wait 30 sec, turn phone on 6) reinstall app on phone and sign in, 7) go to devices, 😎 add the device back (it will want to turn Bluetooth on at some point, if it asks, hit ok), 9) at this point the watch should give you a four digits code.  If it does not,  you will have to start over.  If it does, enter the code in the app and okay through the setup process.  You can text yourself to test, but you must immediately close your app after sending or it won't show up on your watch.  A nice feature seems to be that if your message app is up on your phone it won't be sent to your watch (obviously you don't need to be notified if you are looking at it).  Sometimes I have to do this twice, but it does always seem to work after that.

I followed the steps in this article.  It took several minutes and a couple "uploads" but my Blaze is once again fully synching.  My problem was the Blaze would start to synch, get about half way done, then start over.  It would just keep repeating that cycle.  I went to Settings, then Bluetooth, tapped on "Forget This Device".  The Blaze reconnected.  I then went back to the app and clicked on the update button, and this time the synch bar completed.  Moments later, I got a message that said "update complete".  My Blaze is now working again.

Same thing keeps happening to mine. I have fixed it two times. it is very annoying actually. I am currently having the issue again.

-Bluethooth is on

-blaze is fully charged

- blaze right next to phone

- have great signal on my phone and Wifi too.

Just a warning @MietteTH removing the Blaze from the account, only tells Fitbit that you dont want to use the tracker anymore. It will not help in a stnc problem and any unsynced data may be lost.

The restarting of the phone, shutting the phone down, restarting the tracker three times, updating tge app or removing the app, and the biggest fix is usualy removeing it from your phones BT is what works.

Dont use wifi - turn it off and use data instead.

The use of wifi teally depends on whether your on android or not. Android phones use the same antenna for both Bluetooth and wifi, the others don't.

Hi. I was constantly having a problem syncing - tried everything that
everyone posted and still had the problem. This has worked for me; so
simple yet I've have not had one single problem since...

Just dont use wifi; turn it off and switch data on instead.
Turn on bluetooth and open up the fitbit app.

It's something to do with clash of Bluetooth and wifi frequency and this
resolved it for me.

Hope this helps you as I know how frustrating it is.

You must not have had this problem, or perhaps you do not have an Android.  Actually, I have found the opposite to be true in my experience.  The setting gear in my Bluetooth disappears and I can't take the item out of my Bluetooth list when this problem occurs. Turning off / on the Bluetooth, and turning the phone on / off had NO EFFECT without me disconnecting the Blaze from the app entirely, and reconnecting it as if it were new. The deleting and reinstalling the app is also a necessary step.

This problem is not fixable on an Android Galaxy 6 by the methods they have posted.  I've tried those steps and they don't work.  I posted the only thing that works for me, and I have to do each step in that order.  Believe me there has been a lot of trial and error.

As far as losing things, I haven't list any yet, but it's the risk I have to run if I want messenging on the Blaze to work.  One of their supposed solutions involved resetting your phone to factory settings.  You lose plenty of stuff doing that, and it flat out doesn't help to resolve the problem at all!

[celiawheelia]

Try switching of your blaze tracker, this is the thing that resolves things for me. It's in settings, bottom option is shutdown. Leave it for 5 or 10 mins then press any button and it will switch back on. Then try resyncing. 

[MietteTH]

I missed something in my list - you have to delete the device from your Blaze (dashboard, devices) if it won't delete from your Bluetooth (no gear is shown, no reaction when you try to remove it).  That's where, when you add it back like a new device you get a four digit code.  That is the part that I find necessary.

that did not work

Has anyone tried this:

1. Turn Bluetooth Classic mode to "Pair"
2. Pair device (phone)
3. Turn Bluetooth Classic mode to on?

I am so tired of the error message when my Blaze refuses to sync. I am beginning to think it is not worth my time.

[sebablasetti]

Just in case, something that worked for me. Mine wasn't syncing until I realized it started happening since I changed the location detection of my account to automatic (something like account > advanced > location detection). I turned off auto location detection and it started syncing again.

[tmacker]

How can anyone in their right mind consider this "solved", when 1000s of users are still reporting problems, even after applying the mis-labeled "solutions" that don't fix the problem?

[SilviaFitbit]

It's great to have you here @tmacker! This thread is marked as solved as this was a syncing issue back in 2016 and the troubleshoot provided worked for the first user. If your Blaze is still not syncing then try these steps. 

Hope this helps! Keep me posted.
