Suunto Vertical 2 – Bluetooth issues: connection loss after a few minutes and/or after stops”
-
Hi everyone. So, I did a test with two different types of external heart rate monitors: the usual Smart Band Heart Belt and a supposedly inferior brand called “Coospo.” It was disappointing. I even recorded an activity that didn’t require GPS (dancing) for the test…
Using the Suunto strap, after a few moments…
Now with an external one, Coospo brand…
In my case, it’s clear: my original headband, after being serviced and replaced (theoretically) with a new one, has stopped working again after 7 months. I’ve tried hardly washing it… only by hand. I’ll send it to the repair shop tomorrow, as it still has a year of warranty left. After that, I’ll sell it in case anyone wants to continue the crusade
. I’m going back to the Polar H10… -
It keeps on yesterday I mad a longer trip after the first break the signal got lost and didn’t come back
This time just the vertical 2 and the suunto HR
It sucks
-
@manno02 I can get the signal back disconnecting and reconnecting the HR sensor, I know that is far from being ideal but at least is a workaround
-
In my screenshot above the area when the sensor is disconnected is flat lined, as other commented, I would prefer to have no data.
Possibly it’s a limit of how data is represented having to link two values?
I had another occurrence of this bug today and is always the same behaviour.
-
I asked Suunto for a hardware service on the watch but until now no response I will wait for it because I don’t want to change to the competitors
-
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…
