HR sensor not always connecting

[TiagoSPM]

once, when the battery was below 10%, the original suunto belt with new batt, never connected. No matter reseting connections. Then recharged the watch til 21%, turned off wrist HR, then back to connection! Another time, didn´t notice the batt was below 10%, out for a run with the belt, HR was recorded just on wrist… wich accuracy is always worst…

I had this problem. Its reported and fixed on next FW update. This is a veru specific scenario it happens. Reboot fixes it

I Also had a strange disconnection few weeks ago before an important race.
The sensor of my HR suunto belt disconnected from my SV. I’ve Tried everything I could (unpairing - reappairing, changing battery, changing belt, SV soft reset, restart…). Never succedeed to connect it again. No reasons, It had worked just fine for hundred of hours and few years…

I resigned myself to buy another sensor, It works fine. I’ll try the old sensor again someday or with my wife’s S9pp to see if it still works.

@Dimitrios-Kanellopoulos

Reboot of what? The watch?

I can also confirm this issue is the same on the Suunto Vertical

this makes me think it is rather a strap/sensor issue than a watch one.
Can you rule out that both BT connections are in use already?

[be1t0n]

@Egika Sensor this sensor can connect to more than one thing at a time and is connecting to everything else as expected. The watch will allow me to add it as a sensor but (usually) won’t connect to it for use during an activity.

When I’m at the gym it would only have my watch to connect to and nothing else. At home it would connect to my watch and to my bike trainer.

These all worked perfectly until recently.

I would agree that the issue is with the strap if it wasn’t for the fact that it connects to everything else without issue.

@be1t0n thank you for clarification.
I am out of ideas now…

@be1t0n happened to me as well couple of times. I had to pair sensor again. It had nothing to do with bad strap or low battery.

[be1t0n]

@Likarnik yeah, pairing again made no difference for me. Really odd.
