Suunto Vertical 2 – Bluetooth issues: connection loss after a few minutes and/or after stops”
-
The watch and phone are connected via Bluetooth, and I’m receiving notifications, but the app shows no connection. I turned Bluetooth off and on on the phone, but it didn’t fix the problem. What else can I do?
-
Bluetooth connection to Garmin HRM crashed after few minutes. Logs sent 28.04.2026 21:44.
It’s so frustrating, that bug present few FW ago is boiling my blood again. -
Just reported to Suunto suport by email similar issue between Suunto Run and Suunto Chest Strap. Changing to Duracell 2025 3V batteries didn’t helped.
-
I also reported the issue (race s with polar oh1+ in my case). Got the usual blah blah reply (restart your watch, delete the connected device and repair again)
I suggested they first look into their software and pointed to various threads on their forum about the subject.
Strangely only the heart rate sensor lost connection. My stryd kept working during my athletics training.

@elbee got that answer to… Did the reset just to be sure… Got disconnections on the training immediately after…

Hi, I experienced this today too. I just sent data to Suunto (17:36 on 05/30/26). I was using custom activity tracking, live tracking, route tracking, and an external Polar H10 heart rate monitor (new; my Wahoo cycling computer picks it up very quickly at a distance of 15-20 meters). Anyway, that’s what happens when sensor limitations are affected by the system.
-
@Elmiuel today besides the disconnections I noticed the HR is completely out of sync.
This issues seems to happen on several Suunto models
Suunto Run + Suunto Chest Strap

the same issue here on vertical. on top of disconnecting hr belt (polar h10) watch connected silently to my daughter hr belt (also h10) I was using previously and is not paired to my watch anymore. logs sent
-
@dombo wow, that’s impressive…

It seems that suunto is not really interested in solving the problem I was in contact with the support several times and reported the problem and sent the logs but now they closed the ticket without any information

You always get a “we close the issue due to inactivity “ mail. It is beyond comprehension how stupid this mail is. Apart from complaining about bugs, I also complain about that mail.
Then you get a reply like “that is an automatically generated mail and we cannot do anything about it” Then I explain they are Suunto, Suunto sends the mail so they are the ones that can do something about it.
If everything is how it should work, a support engineer should have made a new ticket for the development team and the ticket that is closed is only the support ticket. But like I said, if everything is how it should work.
I asked some follow up questions about the bluetooth connection issues, but haven’t heard since…
