Heart rate monitor #9

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Reasonably priced Bluetooth heart rate monitors are beginning to enter the 
market, for example the Zephyr HxM Bluetooth @ $99:
http://www.zephyr-technology.com/9600.0112.html

Some other apps, like SportsTrackLive, already have support for these 
monitors:

Would love to see Bluetooth HxM support in My Tracks.

Bluetooth sucks my friend. If you want any kind of vitaldata, ANT+ or something
similar is required. Bluetooth is not a choice when battery life matters... 
Think
about a bike tour of 3 hours... with BT - no way.

The real world says differently. My Zephyz HxM BT hasn't run out of power on me 
yet. 
Zephyr claims up to 26 hours of use on one charge, although I have yet to go 
near 
that long on a single workout:-)

I leave BT active all the time on my phone and still go a day before I have to 
charge. The battery is much more sensitive to streaming 128Kb Internet radio 
and 
following me on Google satellite map view while I'm working out.

BT telemetry is definitely the way to go. BT HxM for people and BT OBDII for 
vehicles 
both work great.

@joeellet. Actually, I have not touched the Zephyr so far. I'am very interested 
in
this and I'am glad you answered and corrected me about this device. When talking
about power consumption, I did not meant the Zephyr itself - this device may 
stay
alive for a couple of hours like an external BT-GPS device with internal 
battery. I
was thinking about the mobile itself - with GPS and BT enabled, I bet the 
mobiles
battery will be the weakest part. And, if you want live maps and use e.g. GPRS 
or
UMTS too, it is getting more difficult. 

Anyway, I would love to hear from you about your experiences using the Zephyr. 
Can
you tell us what mobile phone(s) you use and what kind of software? Can you 
tell us
about your focus? Are you running and do not need the display/map during the 
workout
or are you cycling and need the map etc. I think it is necessary to understand 
the
goal/environment/kind of sport/workout type, when discussing this 
functionality. E.g.
If you "only" run 10km you'll be back within an hour... if you go sailing 
you'll be
back after a couple of hours.

I'am looking forward to hear from you.

I'd like to report my experiences as they are probably similar to joeellet's. I 
am
currently using the Zephyr with the sportstracklive app on my HTC Desire. I 
have so
far only used it for running, max 50 minutes per run. After this, the battery 
is just
noticeably drained, maybe around 10% lower. This is with display off, but GPS, 
wifi
and bluetooth on. Music playing on my bt headset during the entire run (this is
probably the big drainer). There is no significant amount of wifi or mobile data
traffic during the run as I don't use the map or stream music.

My routine - usually around 2 hours "running" which is interval training, pace 
varies 
from jog to sprint to keep the heart rate where I want it.

I listen to streaming internet radio most of the time I'm exercising although 
if I'm 
in an area that doesn't have good 3G coverage, I'll switch to the music player. 
I use 
corded headphones when I exercise, so there's no Bluetooth load there.

Sometimes I use mytracks and sometimes I use another product that supports the 
Zephyr. In either case I start recording and then head off. I have my phone 
strapped 
to my arm with a Tune Belt for ease of access but I haven't found a phone yet 
that 
has a screen thats useful in bright sunlight so I let the display go dark. I 
don't 
explicitly turn off the map, and I always have WiFi and Bluetooth active, so I 
know I 
could save some juice if I turned off WiFi before a run. Needless to say, with 
a 
Bluetooth HxM I can't do the full airplane mode thing:-)

I use a T-Mobile myTouch that's upgraded to Android 2 so I can use the 
Zephyr... if 
T-Mobile ever releases an official Android 2, I'll unflash and unroot and move 
to 
that so I'm back under the support umbrella... or if T-Mobile stops at 2.1 I 
may move 
to a 2.2 flash to get that sweet new JIT... I don't have any home screen 
replacements 
or other nonterminatable battery sucking software.

I also tried a friend's Droid briefly, but 1) it's too big to strap on my arm 
comfortably, 2) the GPS sucks compared to the myTouch and 3) it still doesn't 
have a 
screen that I can see in bright sunlight. Experiment over after one run, but 
the 
battery usage seemed comparable.

I'm pretty sure I could get a full morning or afternoon (4 hours) out of my 
phone but 
all I can tell you is that the battery is about 40% down after 2 hours.

By the way, I have something that looks like a stick of chewing gum with a USB 
connection that's an add-on battery for an old iPod shuffle. I'd like to find 
something similar but with a bit more capacity to use with my phone. Does 
anyone know 
if there's a small, light weight external battery that would fit in a Tune 
Belt, Fuel 
Belt or pocket... something that looks like a trail bar would be great?

Adding my Zephyr HxM experiences to the thread. I wrote a review about it on my 
blog runningdigital.com 
http://runningdigital.com/2010/06/01/zephyrs-hxm-bluetooth-heart-rate-monitor-re
view/ I'm currently using an HTC Desire, SportsTrackLive and the HxM hrm with 
great results. Bluetooth isn't as battery-hungry as many people suggest here 
and in other forums. Accessing your screen often to check the stats of your 
workout draws far more from the battery than what Bluetooth takes. Starting my 
workout with a complete charge, a recent 2hr 14min run with the HxM, listening 
to podcasts throughout, phone in normal mode, mobile network connected (mail, 
Twitter, Facebook, updates, etc. all available) took 30% from my battery. 
Screen was accessed four times during the run.

On the subject of BT heart rate monitors, I've also used a Polar WearLink+ BT 
hrm made for Nokia for over a year, nearly every day usage, including runs 
lasting over four hours. (Nokia N79 Active Edition) Similar battery usage 
statistics with that setup. (The Polar BT hrm is only compatible with the 
Sports Tracker app)

Just thought I'd mention this :) This is also the reason why we've not given 
much attention to My Tracks lately. So basically, it's done - it'll be 
integrated back to the main app :) We've implemented both ANT+ and bluetooth 
support (since few phones have ANT+).

That's excellent news, especially since this enhancement has been marked at low 
priority. Another Google 20% project that makes it big time.

What will be the lowest Android release this will run on? Will the new My 
Tracks release continue to be compatible with Android 1.6? The SDK for the 
Zephyr HxM mentioned that it required release 2 or above.

It looks like Garmin, Nordic and others make USB ANT+ adapters. Will those be 
supported? Would probably make a lot of people who already have expensive body 
monitors very happy:-)

My Tracks will continue to be compatible with Android 1.5, though some features 
are not available at 1.5 and 1.6, such as voice announcements.

We really haven't tested heart rate monitoring at anything but 2.1 so far, 
that's one of the tasks for bringing it into the main app :)

We haven't added support for USB ANT+ yet (not sure if there's a way to plug 
them into an Android phone), but we did add support for bluetooth ANT+ adapters.

USB female to USB mini male adapters and cables are as cheap as $5. That should 
connect an ANT+ stick to most phones.

Not sure what you mean by voice announcements only available at Android 2, 
since My Tracks announces my stats every few minutes even when I'm using my 
myTouch, currently a 1.6 phone. Are announcements getting enhanced?

Yes, but Android by default is configured to act as a usb device, not as a host 
(that you can connect devices to).

Android TTS (text-to-speech) is available since API level 4, which is Android 
1.6 - meaning it's not available in Android 1.5. Likewhise, Bluetooth support 
for applications is only available since API level 5 (Android 2.0).

The Texas Instruments WiLINK 6.0/7.0 standard based chips utilize the ANT+ 
protocol.  Phones with the TI chips will be able to be a head unit for ANT+ 
transmitting devices such as power strain gauges and heart rate monitors.  The 
software would need to be able to interpret the data being sent to it for 
interoperability.  This is the Texas Instruments press release back in February:

Another press release from TI and the ANT consortium indicated phones with the 
WiLINK will start showing up at brick and mortars around Q3/2010.  An example 
would be the Droid X which has the WiLINK 6.0 standard.

There is a broken link within the press release of my last comment that is 
useful to keep an eye on. It's the ANT+ product guide. 
http://www.thisisant.com/modules/mod_product-directory.php  Hopefully HTC and 
other phone manufacturers will add to this list soon.

Recapping: Current phones using a WiLink 6.0 chipset are ANT+ capable, 
requiring a firmware update and of course an app. Phones with the WiLink 7.0 
chipset are ANT+ ready, again, with an app. 

MyTracks said ANT+ support will be added in a future release. (comment 9, 
above): http://code.google.com/p/mytracks/issues/detail?id=9#c9 

"Handsets leveraging the WiLink family of solutions supporting ANT-enabled 
technologies are expected to be available third quarter 2010" -from the Texas

Sandor, your priority is perfect. I can get a bluetooth sensor (Zephyr) today 
that will work on virtually any Android V2 phone but Android phones with ANT+ 
support are rare to nonexistent. By the time ANT+-capable Android phones are 
widely available, I'm sure you'll have the support in place. Many thanks.

Original comment by barcelon...@gmail.com on 29 Sep 2010 at 10:21

GoogleCodeExporter commented 9 years ago
I'll give you an update but no eta.

I have uploaded code to my clone which can talk to a Zephyr hrm.  I can see 
that a number of people have made clones of this.  So a few people are probably 
playing with it.

Unfortunately the code is far from complete.
- I know it has bugs.
- It performs horribly.
- It has stability issues.
- The database format is not fixed.  So data created with this version will 
likely not be compatible with future versions.
- There are no tests for the new code.

I am on my second data model, but I am not at all happy with it.  Here are the 
design constraints:
- It should be compact in the DB and RAM for people who don't use sensors.
- It should perform decently for people who do.
- It should be flexible to accommodate future sensor types.  Currently I care 
about power, heart rate, cadence and temperature.  Other people like Rodrigo 
want to use this for pilots who have very different variables they want to 
track.

The first design added a few extra columns to the trackpoint db.  That is 
wasteful for people who don't use sensors.

The second design had two tables one for trackpoints and one for sensor 
readings.  Without an index the resulting join is painfully slow.

I think what Rodrigo and I decided to do was to add one optional string to each 
trackpoint.  The optional string will not cause much wasted space for 
non-sensor users.  The string will be a serialized protocol buffer.  Protocol 
buffers are good at being compact and easily extensible.

Since I have never used protocol buffers in Java or Android it will take me a 
little while to come up to speed on it.  I doubt anything useful until sometime 
next week.

"...publically available ANT+ enabled (yes, firmware and all) phones.  Check 
out the below pics showing it picking up a few ANT+ sensors that are out there. 
Sony Ericsson Xperia X10 Mini (Android)[...] Yes, the platform will allow 3rd 
party developers to take advantage of the ANT+ chipset right from the start.  
It’ll also be the start of a family of devices, for example the X10 Mini Pro, 
which has a built-in keyboard."
http://www.dcrainmaker.com/2010/09/my-24-hour-trip-to-ant-symposium.html 

Sony Ericsson has also released LiveView, a small 1,3” OLED-display bluetooth 
gadget. The demo video shows it can present the heart rate from the phone. 
The big question is if the gadget is water resistant, like IP-rating IPx6 or 
IPx7 so you could have it mounted on the bike when you train in the rain.

(I'm not related with any of the blog writers, so I only hope that the 
X10-phones already sold is capable of ANT+. But it still requires Android 2.x, 
wich unfortunately SE still doesn't have released for their mobiles.)

I have included a release apk if anyone wants to play with the Zephyr hrm 
pairing.  I have used it a fair bit and it seems to work fairly well.

That said we are not confident in the changes and want to stabilize the app 
before I go and break lots of stuff.

I want to stress that this is an experimental build.  If you choose to try this 
please backup your tracks before you start.  No guarantee that your tracks will 
not get corrupted.

If you are brave and installed this anyways please report your results.

Hi. Thanks! I'm testing it now. 

My preliminary comments:-

Using Nexus One, 2.2 Cyanogen 6. Zephyr HxM.

Sensor Options Works well so far. 
Sensor State will only Connect/show Sensor State once Track recording is 
running, would be good to have working Connection/Sensor State when not 
recording too.

No cadence/accelerometer data displaying.

How do I access the logged data? Will it be embedded in GPX or other existing 
export files?

If you want me to test anything specifically, just ask. 

I'll keep testing and upload logs once I get some more data/test runs.

Original comment by matt...@gmail.com on 21 Oct 2010 at 2:42

GoogleCodeExporter commented 9 years ago
Yup the sensor is only connected when recording.

I was not able to work out the cadence from the Zephyr.  That should be fixed 
soonish.

The heart rate can be seen on the chart view or in TCX files.

I'm more just looking for general feedback and to see if there are any crashes 
left lurking in the app.

Probably both related to the experimental state of this build, no initial
migration of old data:
- FC when I installed the experimental apk over the top of the old MyTracks
install, 'Clear Data' from 'Manage Applications' fixed it.
- I tried to restore the backup with some success, I can see that there are
tracks under 'Tracks' but can't load them and review them anymore, something
that I guess will receive polish as part of the upgrade process.
