Suunto Vertical 2 – Bluetooth issues: connection loss after a few minutes and/or after stops”
-
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…

At least the support sent a reaction:
„The frequent disconnections and reconnections are occurring on the BLE firmware (Bluetooth) side.
It is worth noting that the longest disconnection period of the heart rate belt was approximately three minutes, after which it successfully reconnected. Therefore, the issue is not an inability to reconnect, but rather frequent disconnecting and reconnecting.
Based on the current analysis, the issue appears to be related to the connection stability between the BLE firmware and the sensor.
However, the current logs do not provide enough evidence for us to draw a definitive conclusion. In order to further diagnose the issue, we need to attempt to reproduce the problem. Therefore, we will now escalate this matter to our testing team for reproduction.“
We will see …

Hi, to add some information to the matter, I noticed that if I had “WRIST HEART RATE” disabled, it wasn’t detecting my external chest strap (a new Polar H10). I selected it to avoid interfering with the watch’s optical readings. Therefore, after enabling wrist heart rate in the exercise options, it automatically detects the strap and monitors my heart rate during exercise.
I would have to test if, after a medium-length stop during an activity, refueling, a forced pause, and restarting the activity, the heart rate recording with an external band continues… I understand that it will always be available with the optical sensor of the watch.
