Polar v800 bluetooth problem

So for a while I really liked the messages coming to my watch from my phone. But after a while it just stopped.

I did not really mind, I could still see the messages on my phone and the Polar V800 did not display the full messages anyway.

But then my Polar V800 stopped syncing my data… say what? How can I see the work I put in to that workout in Polar Flow?

What ever I tried, it just did not work. Deleted the Bluetooth connection, tried to get the connection back. Deleted the Flow app, and put it back.

Nope did not work! I tried it all, but the bluetooth connection did not came back. No more smart messages. No more data tot Polar Flow.

Now What!

    Thanks that worked well: I’ve been pulling my hair out.

    Any advice on how to pair the heart strap? It stopped working too…

    • Hi Rohan,

      Did you remove the heart strap from your phone? At settings?

      Please remove it and reconnect.

      I guess this will work! Or! can your phone find the strap? If it cannot the battery may be dead.

      You can buy a new one in any online shop or offline shop. You don’t have to buy the polar one (it’s way overpriced)

  • This is all kinds of fantastic.Does your advice change at all if you’re not leaving for another job…but rather to start your own business? I’d imagine all these apply, especially the network bit, but would you add anything?

  • Alec

    thanks for post and procedure. Unfortunately this did not work for me. I may simply have a bluetooth problem on the V800…

  • Xavier

    Mijn V800 was gekoppeld tot de update.
    Dacht dat het een grap was om met uurwerk tegen iPhone te tikken…
    Hartelijk bedankt!

  • Ana

    It did not work for me … 🙁

  • Ron

    Worked great. Thanks!

  • Szymon Frydrych

    Hi I’ve tried to do your solution but it didn’t work.
    Notifications comes but only if I reconnect phone manually from phone settings menu.

    Sync data works only when I delete connection in phone and in my v800. Every next trying doesn’t work.

    Problem appeared when I changed phone to iPhone 7

  • Rj

    I have the same issue as Szymon, I can pair the v800 with my iPhone7+ , and it will sync. Second time around it won’t work and it appears to be a Bluetooth connection issue. If I watch on the phone’a Bluetooth settings screen when the watch is trying to pair it flashes between “not connectected” then briefly “connected” then “not connected” and eventually fails.

    I tried the solution offerred here but it didn’t work for me either.

    I’ve only had this issue since switching to iPhone7+.

    • Antoine

      Hi all,

      Get always the same error as Szymon and Rj, but with a Samsung Galaxy S5 Under Android 6. Asked Polar support from France and Finland, they do not seem to care.
      I have a LTE (Bluetooth Smart) analyzer / logger. I have the same conclusions as Rj: when already synced once, V800 send a message to change LTE status, so it was on, it is switched off! Then, pairing and syncing fail … what a pity … It appeared only since the latest firmware of V800 or before. Strangely, I don’t have the issue with a S4 mini Under Android 4.4.2 …
      I’m getting puzzled. Did you find any working solutions / workaround other than deleting paired devices from phone and V800?


  • gmb

    thank you, it worked!

  • Manu


    I couldn’t sync the V800 with my iphone6 anymore. Don’t know why.
    The phone wouldn’t detect the polar, so I canceled the polar connection in the bluetooth menu of the phone and canceled the phone in the connected devices. I also restarted the iphone, but as it still didn’t work I updated the Polar on the computer.
    And then miracle it worked again, the iphone detected the V800 and I was able to synch it, without deleting the Flow app.
    Thanks for the tips.

  • Frank Jensen

    thank you!

    Worked perfectly

  • Wynn

    Thank you very much! I was getting very frustrated. Your solution worked!

  • Patrick

    Perfect – master piece. It worked for me. Thanks @Theo
    Small addition though:
    If after step 9 the APP is not asking for to press the lower left button on your watch
    Step 9A: within the APP go to “more” -> devices -> info -> how to sync?
    and continue with Step 10
