HRM RUN not disconnecting after workout.

It's not just the HRM-Run. Any and all external sensors will try to connect to a Garmin device if left opened (i.e not turning them off manually). They are supposed to know when you aren't wearing them and not continue to transmit data but that is a lie.

If you don't manually connect/disconnect the chest strap, and it doesn't matter if that strap is Garmin or not (I have a Polar H10 and Wahoo tickr-x, it happens to them too) you leave the ability for the strap to connect open and the watch will try to connect to it once you are in range of it. This then makes the OHRM turn off because it thinks you are wearing the strap, even in 24/7 mode (this only pertains to if you keep the OHRM set to auto). That "connection" usually doesn't last long, but it will happen over and over and over throwing the OHRM out of whack and frankly not doing the right thing. In theory the watch should know you are not wearing the strap anymore....but that's just a theory.

I learned this the hard way when I owned my Fenix 3HR. You are stuck with manual connect/disconnect. Just be sure to check if the OHRM actually turns back on after disconnecting the chest strap, the 935 has a nasty bug where it doesn't always turn over to the OHRM and a power down is the only way to get it to start up again.

Side note here but the watch sometimes "sticks" after doing an activity where you used a chest strap and did a manual disconnect of the strap. It treats HR data and active cal counts like they were BEFORE you went into the recorded activity. I've left a workout with a HR at 137BPM (recorded by the strap), saved the workout, disconnected the strap and the OHRM will then say my HR was 67 bpm (after a good 30secs AFTER it locked on). When looking at the HR chart from the widget it looks a lot like what that chart looked like BEFORE I went into the workout and refuses to accept my current vitals into recording. If you toggle the "Activity Tracking" option on/off, it fixes it....most of the time.

And yes, after 3 years of using Garmin devices i've come to the conclusion the only good thing i've gotten from these devices is that they have made me a better Macgyver.

Never seen this problem. When I start an activity with WHR on auto, with an HR strap the strap is connected WHR turns off. Once I’ve stopped and saved the activity, WHR turns on.

Which begs the question, are you stopping and saving the activity?

A lie? A bit of an overstretch to say the least. Sensors transmit for a short period after use before shutting down. They will only resume transmitting when moved, or in the case of an HR strap, when wetted or put on.

not turning them off manually

Besides, how do you turn off a non-magnetic speed sensor? A GSC-10 speed/cadence sensor? A heart rate sensor? There are no on/off buttons.

I have never, manually disconnected any sensor in all the years I've owned a Garmin device.

the 935 has a nasty bug where it doesn't always turn over to the OHRM and a power down is the only way to get it to start up again.

Never seen this either.

Well Phil, you apparently have the perfect watch that never exhibits any problem, ever. And that's just from me noticing how you respond to devices on these forums. I have watched in real time my HRM-Tri with the connection left to open (as in just having the sensor status set open so in the condition of wearing it, it should just be connected) and watched it "Connect" to the watch while it was just sitting on the shelf, only to then go into "not connected" and then back to "connected" over and over and over turning the OHRM off (because the OHRM is set to auto), then on, then off...you get the picture. And this goes back to my first days with my forerunner 235. I stated this point blank to a Garmin Rep and they flat out told me yep, the watches do this. It's never been fixed, but then again you wouldn't know since you never seem to have any problems.

F.Y.I you manually turn on/off the connection to a sensor by going into Sensors and accessories in the watch, find the paired sensor, turn the status on, and connect, and then do that in reverse to disconnect after you save your activity. As for saving the activity, yea of course....when the watch (SOMETIMES) decides to not to give me the option to save and just goes back to my watch screen. Though I will admit the activity has always synced to GCM in those cases. As for the 935 OHRM not turning over, that was confirmed by the beta team as a minor issue after I reported it (four months ago). It's happened a handful of times to me, but it's happened nonetheless.

And before you tell me what kind of Apps or data screens or watch faces you have installed.....I have had these same issues crop up on a fresh watch, out of the box with nothing but stock on them. I've had these same issues after a factory reset with nothing but stock. Perhaps you don't seem to have these issues because you don't actually watch for them?

Like Philip I haven't had any issues with the HRM Run. Yes, when I save at the end of an activity, I see messages that sensors are reconnecting (which I have always found a bit odd). Most sensors will shut down after a couple of minutes inactivity, and only restart when you move them. And after those couple of minutes, they shut down, and the OHR takes over. Just take the strap off and set it down.

jstpassaro - I don't have direct exerience with them, but this may play a bit differently with the store-and-forward ability of the HRM Tri and HRM Swim, which are intended to operate seperately from the watch, especially if there is saved data still being forwarded to the watch - this may keep the connection open longer. But again, I would be surprised if taking the strap off and leaving it motionless doesn;t lead to it shutting down after a couple of minutes. Also, I am not sure whether opening the sensor settings on the watch actually forces the strap connection to stay open.ie. the very act of going into the settings to turn it off "proves" that it is still open, whereas if it had just been left alone it would have shut down on it's own.

Well, I guess I've got a perfect watch that never exhibits any problem, ever. I've never experienced an issue with the sensors after stopping an activity.

Jstpassaro, I honestly don't find your posts helpful and I have to wonder why you've continued to use Garmin devices for the last three years if they've given you so much trouble.

I have watched in real time my HRM-Tri with the connection left to open (as in just having the sensor status set open so in the condition of wearing it, it should just be connected) and watched it "Connect" to the watch while it was just sitting on the shelf, only to then go into "not connected" and then back to "connected" over and over and over turning the OHRM off (because the OHRM is set to auto), then on, then off...you get the picture.

To be honest, I'm not sure how to respond to this, mainly because I don't have an HRM-Tri but also because I'm unsure exactly what process you are following. As far as I am aware, the device will not actively seek any sensors from the sensor pool until an activity is selected. It's then open slather for the device to look for any sensor that might have been activated. Now, as already noted, when a sensor is moved it becomes 'active'. To suggest otherwise is to assume that the sensor is active 24/7. If that was indeed the case with battery driven sensors then battery life would be severely reduced to a matter of days. Clearly that is not the case. And of course, if the device was continually searching for sensors, the battery there would be adversely impacted.

I'm still unsure what you are doing to cause the device to constantly seek active sensors - HR strap or otherwise. As noted above, it might also be that re-activating the sensor from the pool causes the device to look for it. Leave it alone and perhaps the perceived problem is not really a problem at all, but more a matter of operation.

OK, when go to settings, sensors I see that the FR935 says searing for my Wahoo strap HRM. When I put the strap on, it connects to the FR935 and I assume the strap HRM is overriding the OHRM. However, as soon as I remove the strap the Wahoo no longer transmits the data the FR935 returns to searching for the Wahoo and the OHRM takes over.


FYI - I would have thought if the FR935 was continually searching for sensors I've attached (I have cadence sensor attached and it shows searching as well) that the battery life of the the FR935 would be affected but, I got two weeks out of my last charge that included three bike rides and a spin class where I was in activity mode.

I suspect when you look at the sensors in Settings, Sensors the device will search for a sensor. However, when an activity is not selected, then the sensors are not continually being looked for. The device only 'looks for sensors' when told to do so by selecting an activity.

I think you a correct. Otherwise, if the FR935 was continually looking for the sensors, the battery would drain very quickly.

Hi, is there anyone else who's having problem with HRM RUN not disconnecting after workout ?

No. Never.

After every training I have to go to settings, sensors and manually disable HRM connection.

Wait. Have you removed the Strap from your chest? Have you taken it off before doing that? If not it keeps sending. As long as it's sending the 935 wouldn't turn on the optical.

If I don't do that OHR won't start and my FR935 will continue to read data from HRM RUN /

Ofcourse it does.

at the beggining nonsense data, because HRM is no more connected to chest strap

Are you using leatherman for that?
