Ah, of course. Note to self, 'think-read-think-then write'.

Hi,

Just received the Polar WL+ Bluetooth in the mail today and spent the last few hours on studying the protocol. For some reason the belt stops transmitting after 17-20 data points. Here's the hexdump of one data set:

... and there it stops. The belt seems to need some prodding or it goes back to sleep. However sending random characters like space or cr just makes it go silent. Blah.

The second byte seems to define what data the line contains. The lines with fe 08 contain heart rate data: the sixth byte is most likely the heart rate. The fourth byte is a counter (but why is it missing on line 16?).

BTW, I don't see why it wouldn't be legal. Polar also sells the Bluetooth heart rate monitor as an OEM product.

thanks for the update, the "save as default" option works now

I forgot to ask if you could add the opencyclemap as a map source. I think it should be easy if there is openstreetmap already available. I prefer the cycle to the street as there is possible to read the terrain (topo).

Upgraded to 1.65 and working well. WOuld love to see the record button colour change also is there any chance of using the led to blink whilst recording mode is on?

Also, as per my PM to the developer, are any bike users wanting an auto start stop function so we can get riding avaerage as well as journey average.

Use this application everyday on my ride two and from work, just need to save up for an HR belt

Hi.

Feature request: Is possible to make scale/ruler on the map screen in one of next versions of eCoach?

Hi, firstly what a great app. Well done and thank you.

Now for my question and suggestions. I train mostly using heart rate and like most sportsmen work in various HR zones (recovery, aerobic, anaerobic etc...) before I go out and purchase a compatible HR transmitter belt, does ecoach display full LIVE HR data including a way of showing what target zone your in? i.e will my current HR and percentage of Max be displayed on the screen and does this display actively show if I'm above or below the targeted zone?? Does it offer any audible or visual warning when you go outside the targeted zone like most HR monitors do?

I'm pretty sure ecoach probably doesn't do these things. If so is there any plans In the future to add such functionality??

Whilst I'm at it I might as well add my wish list, so here goes:

1. All live data dispayed on the map screen, maybe in a small box. Items such as 'Current speed' and 'Avg speed' 'Live HR data and zones' ' Exercise time' etc, It's good to have the data post ride but having it easily readable in one display during is even better.

2. The ability to warn you visually and audibly when you’re working below or above a target HR zone. Maybe your current HR and HR Percentage of max could be displayed and be in green or red to indicate if your in your targeted zone. It would also be good if this could be displayed at all times on the main map display.

3. Most HR and cycle computers now have an auto-pause feature so when you stop or reduce you speed to a pre-determined speed the exercise timer stops. Without this when you stop at traffic the average speed and HR get all messed up. Obviously you can manually pause but that’s very difficult and dangerous whilst negotiating traffic.

4.The ability to pre-plan a route and upload using a gpx file. There's some great websites that enable you to map a route and create a gpx ( http://bikeroutetoaster.com/Course.aspx ). It would be great to do this and transfer to your n900. Not turn-by-turn but still a good navigation tool.

I'm sure the more I use it the more I'll think of. For now it's a great app, but if only....

Cheers, Andy.

Yeah, protocol seems to be rather simple. I tested it today and seems to be working just fine. Lets see if I can add beeps for HRM limits... Also burned calories could be nice to see, is there any good formula for calculating it from pulse?

@Sampo, could you add those patches?

Thanks for the great app. Works very good, especially in conjunction with heiaheia.com. (Only: Max and average speed should also be submitted to the site.)

How is porting to Qt going? Any experiences with using the Nokia Qt SDK you want to share?

Sorry - I've been on holiday...

I have gone through this - deleted authorisation from my heiaheia account, then gone through the authorisation process again, and I see it appear under my settings page
Reset my n900 ecoach settings and then tried to upload - no joy, just get the upload failed message.
Where can I get the logs from to see what is happening?
Im on the latest version of ecoach..

I found a couple of good papers on this on my university's site which have got some derived formulas. I'm not too sure what the legality is if I just post the papers here, but maybe you could pm me your email address and I'll send them through?
