How to change HR detection frequency - Amazfit

Hi guys, i've bought an Amazfit GTS and I was unpleasantly surprised when I saw that the shortest range to measure the HR it's 1 minute!
There's a way to change it? Or during the exercise it will constantly check the frecuency??
Thank you!

This setting doesn't apply to exercise mode.

This means that during exercise the measurement it's constant? Because it didn't seem like that...

Sony SmartBand 2 (SWR12) with Z2

Tomorrow I'm getting my hands on the new SWR12 aka SmartBand 2. If you're preparing to buy one too, ask me anything regarding compatibility with the Z2.
After I had some time with it I'll try to write a review and compare the second generation with SWR10 aka SmartBand.
I'm quite curious about battery life. Wondering, if the new generation will last longer on battery without pulse monitoring.
First impressions:
Both the SWR12 core and band are made of different materials than SWR10. It feels more slippy.
Good news is that the SWR10 bands perfectly fit the new core. So you can use your old leather band with the new core.
The new band feels comfortable and the new lock is much better - no way this is going to fell of occasionally.
Great news is that the new SWR12 is compatible with SmartLock (Lollipop). So you can use it as a unlock device even though this is a BLE device. Yup, also works after a restart etc. I tested it very carefully, because I couldn't believe it Wondering if Sony is going to fix this for the first gen SmartBand....
The Heart Rate monitor is working better than expected, but I need to test this more to give a more reliable conclusion.
is it possbile to use heart rate measurements in 3rd party apps (Sports tracker in particular)? which new fuctions other than HR present in swr12 vs swr10?

The SmartBand 2 host app only mentions Google Fit (there is a switch to enable synchronizing pulse rate with it). However there is a note that the pulse data is synchronized only if you measure your pulse using manual control. So for example if you want to measure your pulse every 10 minutes (like the Livelog does), that's not possible. So basically there are two options avaliable: Realtime pulse tracking or No pulse tracking at all.

New strap
Colored notification LEDs
Smart Lock support for Lollipop
Standalone app (no need to use lifelog to measure steps etc.)
Google fit support
Quiet mode (Night mode replacement, probably you won't need to set when you sleep - it should track this without any interaction - for example during after-dinner sleep - still needs testing)

I actually made this thread, because I guess I'm one of the first to get this device. I had huge trouble finding it - even ebay doesn't sell it.
When suddenly I looked at the local auction website "Allegro" in Poland and noticed that the official Sony re-seller called "M-point" has them in stock.
Link to the auction: http://allegro.pl/sony-swr12-smartband-2-czarny-i5653196214.html
Link to the reseller website: http://www.sklep.m-point.pl/4650-Sony-SWR12-SmartBand-2-czarny.html
No idea, if the shop ships internationally.

Just tested and indeed you don't need to use night mode to track your sleep - all is done automatically. That's superb!
It takes about 25 seconds to measure the pulse rate - lets call this a "cold start". After this period it measures in real time.
So take this into account, if you want just to check manually for your PR from time to time you'll need to wait a few seconds for the test to complete. This also applies to SWR12 STAMINA-mode.
Battery
Could you make a test of how long the battery lasts when you permanently measure your heart rate. This would be interesting for me, because the main point I'm interested in is to have a 24h measurement of my heart rate - awake and asleep.
Thx

The heart rate is measured every 10 minutes by default. That way it should last for 2 days.
With Heart activity mode enabled (measures the heart rate more often than 10 minutes (every 5 minutes?) it should last for 10 hours.
Which mode would you like me to test? Also, I'm getting quite much notifications during the day, this could lessen the battery life.
EDIT: I was heavy testing the device yesterday, updating it's firmware, pairing with different devices, measuring heart rate in activity mode for some time etc and the battery lasted for about 28h. I did not use the STAMINA mode at all.

I would be interested in "heart rate in activity mode always on". I understand that in this mode the heart rate is measured permanently and not "only" every 10 minutes (which actually should be sufficent for most use cases).

It's definitely not a constant measure in "heart rate in activity mode always on", because if I peek under the smartband 2 during this mode - it's not always emitting the green light (required to measure the pulse). So it's more often, but still not always on. The heart rate monitoring is only always on (permanent), if you keep the SWR12 app open (and keep the smartphone screen on). That's from my observation.
Difference between normal mode (2 days battery life) and activity mode (10 h battery life)
This diagram was recorded during 16h of usage (14h normal mode - 2h activity mode).

I just fully charged my SWR12. You're right after all. I'm now peeking under the core every few minutes and the green light is always flashing. So yes, in activity mode the pulse is measured in real time. Sorry for my last reply, I made a mistake

Thx for your investigation. So with "always on" the smartband will not last for a whole day. But with "nomal mode" you are able to cover a whole day and maybe a second day.
So using "normal mode" and "always on" for sports and charging the smartband every day in the evening would be a way to go if you are really interested in your heart rate.

I just finished testing the always on mode and I got exactly 12 h and 35 minutes of battery life. It might get even better after a few charge/discharge cycles.
So if I would plan to do an Iron Man challenge, I would need to hurry up
Just kidding.
Thank you very much for your test and your answers. I just saw that the Smartband is now available on amazon.de and I'm going to buy one now :good:

I found something interesting: actually I didn't fully charge my band... Because the green LED indicates that the SWR12 is charged over 90%, so to fully charge I had to charge it for a qouple minutes longer... :sly:
Hi there. When you are using the continuous hr (always on), the only way to check your hr is checking the phone? I would like to use the band to practice sports but I would not be able to check the phone screen.
I know the band doesn't have a display (like fitbit charge hr). But if it was possible to check at least the zone you are (by the color of the led blinking for example) it would be OK to me.
Can tou test if it's possible to check your zone just looking to the band please?
Thanks very much!

Yes - I have installed the new version since yesterday. Steps are now counted immediately - the pedometer algorithm has been improved and a new function has been implemented: navigate back to the (stored) starting point. I could not test this, though. Italian and French are now supported.

Hello, I updated new ROM 2.3.6.0. and in last 13h I have left battery 56% (from 100%).
I have installed it when it appeared. No issues so far.

Update completely breaks HR monitoring - it's consistently showing unrealistic values like 220 bpm for a bike ride in the park?!?
Existing bug with excessive battery drain when using an external HR monitor NOT fixed.
Very disappointed with the software of the watch.

I tested HR in GYM (GRIP) ... after all comments I was surprised that it was more close to reality then before. Average HR 130 and Max 171 on cardio. Similar data I had on Gear S3. Before my max HR was only 140 on cardio and average 110 - 115. As there is no GYM mode I am using Elliptical Trainer
So only problem I see is with continuous HR.
Updated to 2.3.6.0, three days ago. My initial findings:
- HRM seems to be high, at times. On a hike, while descending (HR low), it constantly showed above 150 bpm and up to 180 bpm for about 1/2 hour.
- While swimming, it adds steps. That's something I had noted with previous ROM versions, which was corrected in 2.3.5.0. Now, it's back again. For example, today, entering the pool, steps count was 2700. After a 1600 meter pool swim, the steps count had raised to 5120!!! That's amazing!
It remains to check other features...
i updated this new rom version 2.3.6.0 few days ago and the Heart Rate is more higher than the 2.3.5.0 version (210 bpm !!!!) my highest bpm was 168bpm
Is it possible to dowload the 2.3.5.0 version ?
Cannot measure the heart rate after the update
I just updated and the first bug I noticed is that I cannot measure the heart rate anymore. I always get this error:
"Couldn't measure
Wear the watch above the wrist."
But the watch it is one finger above the wrist, as it should be...

Pace Barometer or GPS ?

The barometer on my Pace is stuck at the same reading. I have tried gently blowing in the hole, cleaning it etc. I also tried a factory reset.
But the altitude is changing. So is altitude determined by GPS or the Barometer ?
Hi
The elevation is measure using the barometer and not by GPS.
Seems your barometer faulty that not reading any elevation. Same time, did your battery life span normal as it in stanby mode (leaving untouch on table) using 10% over 24 hours (plus minus)?
Did you wear it during shower or swimming. Thia watch is only resistance to water splash in small quantities.
Probably you could explain the last successful of elevation reading and then become faulty of the activities you did.

I am aware of this fault & my battery seems fine. I have never got the watch wet & it's only a few weeks old .
The barometer is permanently at 1024 but the altitude does change.

Thanks. There is an app that puts pressure changes on a graph but it's continuous so collect huge amounts of data. I would of thought that the dev could easily add interval measuring.
It's a waste to have a barometer that has a limited use. It could be like the barometer on a Suunto watch.

Does it finaly possible to calibrate altimeter manualy? skydive use

Hello Everybody,
So after a lot of reading, it looks like this wonderful Amazfit Stratos could perfectly matches with all my new hopes and finaly
substitute for a perfect relation equipement/price ;my old school Suunto X6)
Though, there is often a "but",
I'm pretty sure this special use could interest a lot of people in specific outdoor activities, and hope we will find a way
So
I'm skydiver and would like use the watch at least under canopy for landing. (I doubt about the speed refresh while freefall, but not the matter)
Means I need calibrate manualy the altimeter on 0 (zero) before going in the plane, and landing safely after the jump on same altitude I had calibrate just before
Means probably too, the altimeter should works imperatively on just barometric data...?
Is there a solution to reach my goal? even if I should try to tamper the firmware or kind of push a special room??
Any idea is welcome))
Anyway sorry for my unperfect english
I was planning to build an apk that could do it. Because I also need it for paragliding.
Like configure current air pressure at sea level.
Calculate the current hight based on the air pressure etc.
I know the app GreatFit https://forum.xda-developers.com/smartwatch/amazfit/app-watchface-greatfit-v1-1-settings-t3791516 has the option to show your hight on the watch face.
I would be extremely wary of this. My Pace barometer is pretty accurate but the altitude isn't. I live by the sea so I have the perfect opportunity to test it. There is no way to zero or calibrate.
Interesting.
I was also planning to create an app for this, then I realized where the heck I could get the current temperature from. My pace doesn't have a thermometer, does it?
I am no expert here, but I think we need the pressure AND the temperature to accurately calculate the altitude. The altitude reading from the watch can't be accurate if the temperature isn't taken into account or perhaps the watch just gets the altitude from GPS.
thx for your answers
Anox, for what use do you wish realize this app?
So
I'm pretty sure I had read about the Stratos the altitude is linked to the GPS( after searching again, of course impossible to find
again the intel)
Effectively, On the Suunto X6 there exists also a temperature probe; I don't know if it use it to manage the altitude simultanously with the barometer
Then, looks like could be more simple to build an app than modify totaly a ROM)) that's already good news
How many times it could takes to build this kind of app?
The stratos and pace have barometer sensor, maybe it could be enough to make a try?
(i need specify with Suunto X6, by day I often have 5/10 meters of variation, I could reset and calibrate on the ground, or not,
15/20 sometimes, 30 meters when weather changes totaly though in this case we stop jumping)
I guess isn't either a problem for Istaveren while paragliding, 5 to 20 meters could be corrected by vision and experience?
Finaly

This rumor is quite persistent but was never proven and I'm quite sure it is wrong. From my experience with the pace it seems, that every activity with altitude measurement is starting by using the altitude from the GPS to calibrate and later on some mix of GPS and barometer to measure the changes in altitude. To realize this one must use the data from the pace directly since as soon as the data is processed in the phone app, altitude data is corrected on the base of an online altitude/shape map.

So, with what we have as data;

Amazfit GTR heart rate problem

Hi guys,
I just got my new Amazfit GTR and noticed strange behavior of heart rate monitor. It shows values even if the device is not on my wrist. I left the device on the table for more than hour and any time I looked on main screen there was heart rate value and it was also changing the values. So it wasn't just last value stuck. I tried to run exercise activity while leaving device on the table and it was showing heart rate as well. Not all the time but sometimes there was value and sometimes not. So is the device faking heart rate values? Is it normal behavior?
It is how PPG sensors work, they use the reflected light to estimate the number of beats. Search the internet for more info.
Well, I have another watch with PPG sensor but they don't show nothing when they are not on wrist.
So it will probably not be about sensor type. In this case they for example report my rest heart rate during the night even if they lay next to me on the table so the values will be completely faked.
The sensor works that way, but other devices may use *other* sensors to disable the reading when they detect the watch isn't being used, the accelerometer for instance.

HEyy,
- Also got 2 other product with the same comportment `` Fitbit Charge Hr ´´ and `` Fitbit Blaze ´´ , both detect when they are not in the wrist. Why doen's GTR do the same?
- Also both got more accuracy in Heart rate measurments...Because they are doing it consistently. With Amazfit GTR i only can program it to do it 1min in 1min. Already change it with Notify & Fitness. nothing seems to change....
- Another outburst from my side : heart rate scale doen't save scores higher than 180 BTM !
Are some of them just software issues ?
Regards to all
The heart beat sensor on the GTR is utter garbage. It does indeed fake heart beat results. Also the sleep analysis functionality is totally broken.
Just got my GTR and the heart rate monitoring is way off. Always some 20 to 35 Beats above the real one. As I have some hair I tried it in my finger and in my belly with the same wrong results. The firmware version is 1.3.4.19 which was updated immediately after first turn on. In contrast the free Android app I use is pretty accurate. I will still test the GPS.

I returned the GTR and got another one from another vendor and it has the same problem. I can now say that the heart rate monitoring in the GTR is useless, just a boring toy.
Amazfit admits that the heart rate monitor is "prone to inaccuracies" in its faq: https://support.amazfit.com/us/faq/839
As the heart rate sensor is basically a pulse oximeter which monitors the perfusion of blood to the dermis, it’s prone to inaccuracies.That’s because skin perfusion — a measure of how much blood flows through your skin-varies significantly from person to another. Especially the ones who have dark skin, hairy wrists, tattoo, and scar.

Oddly enough I have found the heart rate monitor to be remakably accurate if worn correctly and over the range 60-110. A few moments ago I confirmed previous results and while the watch showed 91 bpm a simultaneous ECG showed 90 bpm. The problem I have with the HR monitor is that it seems, when the cpu is stressed, to produce crazy results. To get around this I run exercise from the phone and get sensible results from the HR monitor. I might add that I was cooling down after exercise!
Well seems I am testing today. Had the watch about 2 days. I am guessing the watch does NOT show the current temperature? Like that matters. The GPS took about 45-60 seconds to connect, as others had. Seem to do faster NOT on wrist. Now my heart-rate monitor works really good. Tested it and I when I got 86 the watch got 85. did it again I got 84 thee watch got 85. Now I did take it off put it on the rubber mat and it kept going up to about 96 lol Put on my keyboard( light on top of keys) it went down to 40. Yet on my wrist works really good.
