          @salusi I have the same issue, my current solution is to use an old Polar H10 I have lying around.

          There are other threads where people seem to have the same issue.

            Has this issue been fixed? I recently got a vertical (latest firmware) with a sensor belt and my belt keeps loosing connection with the watch.

                It also happens with the Suunto Run. And it’s not exclusive to the Chest Strap. Using Bluetooth phones to listen to music also makes this issue appear. The issue almost always appears after around 1h training, pauses or GPS disconnections during tunnel passages.

                  This evening it happened with my race s and polar oh1+

                  Heartrate band disconnected, didn’t reconnect and the buildin heartrate sensor didn’t take over.

                  My stryd stayed connected though.

                  I will report to suunto support.

                    It isn’t supposed to be taking over.

                      @2b2bff but it seems it does. At least on the Suunto Run. I saved today’s run to report tomorrow.

                      2 issues happened. Max heart rate much higher than registered on the HR chart and in the end I did a pause and the connection to the Suunto Chest Straps was lost when I restarted a few seconds later.

                      The maximum HR registered by the chest strap was 154bpm but somehow on the Max HR in the intervals summary many values of 170bpm (these are wrong) appears. Also it can be seen that the HR chart doesn’t end. It was the pause. Unfortunately Suunto seems unable to solve this issue that affects all watches and makes all data contaminated by wrong measures or lack of them.

                        Sorry to hear about all the problems people have. Have Suunto acknowledged there is a problem and working on a fix or has they already “posted” the fix but it still remains?

                          @Henrik-Nilsson they gave me a predefined answer with the usual stuff… It’s strange how a bug of this magnitude does makes them more proactive to solve it.

                            @Nelson-Diogo I agree. Hopefully they are aware and working on it. It seems wierd selling products that are supposed to be used together and they arent =).

                              I have recently experinced tha same issue with a smart belt bought in february. Lately short disconnections occurred, which had never happened before. Lastly, on Sunday after a couple of short dicinnections, the belt and the watch never reconnected for the rest of the workout. After the end of the session, i restarted another one and the watch saw the sensor without issues. Nevertheless, Given that in 10 years i have replaced several sensors because faulty or dead, i attribute this to the sensor, not the watch. Fiven that i bought it on amazon, i returned it and bought a new one, so let’s see.
                              The suunto smart sensor is not exactly a piece of reliable engineering, actually is quite crap, as i said i replaced several of them, i guess some 5 or 6 since 2015

                                @sindavide I’m also almost sure the the issue I have it’s a faulty Suunto Chest Strap. The Suunto Run is behaving awesomely for me in any other respect.

                                  I don’t have a Suunto chest strap.

                                  I think the problem with mine is a combination of my stryd and a polar oh1+ (although I think the heart rate sensor is irrelevant)

                                  The stryd causes some odd behavior when I do warmup exercises at my athletics club. While doing planks, my watch buzzes due to some signal from my stryd (is my assumption, the buzz is real, the cause is assuming) and after that my watch loses connection to my heart rate sensor.

                                  Last couple of weeks we didn’t do that kind of exercises and I had no problem with disconnecting heart rate sensor.

                                  I suspect the problem is in the watch firmware. It either cannot handle certain signals from my stryd or it cannot deal with disconnecting sensors.
