SEPTEMBER UPDATE: Dynastream released a fix for this in the ANT+ radio service 4.14, so that should be the end of the story, for now :-). Just get the latest radio service from google play. If it works, I suggest that you disable automatic updates.




JUNE UPDATE: Dynastream has finally confirmed the problem, at least for some devices. For LG and HTC phones, it seems to be an interplay between an update from the manufacturer and a limitation in the dynastream service. After some work, they have built a new radio service which should fix the problem. I have the APK, so If you're willing to install a beta version of their radio service, please contact me from the "contact" page above or via email, and I'll send it with instructions.


If your phone is not HTC / LG but you're affected by this problem (that basically ends up with a sequence of ANT_DISABLED notification in my log) please get in touch and send me a log, as it could be a different issue with the dynastream service.


A recent update to the dynastream services (ant+ radio service and ant+ usb service) is causing problems to some android devices. I don't have the full picture yet. So far, what I've seen is:

- some devices cycle between ant enabled / ant disabled
- some devices don't get the ant+ channel, so they can't progress
- there might be other cases that I have to understand / categorize

I'll try to contact the guys at dynastream, because it doesn't look like something I can fix on my side. My suggestions:

- as I always say: disable automatic update of the dynastream services. Do not blindly assume that I can fix things. Dynastream has its own strategy, and it is not well aligned with the needs of my app.

- if you have already upgraded, and are experiencing problems, downgrade. I suggest that you do not get the old services from unverified sources. Dynastream keeps an archive of previous versions on github, and the latest good one is here. You need to click on each service and then on "raw" to download the apk. After that, you have to uninstall the service and install the apk manually.

- I understand that some devices running lollipop do not accept the old services. At this stage, I don't have a fix for that.

update: this problem is fixed in Sportablet 7.8 / Uploader for Garmin 6.8. I've just pushed those versions to Google Play, so it may take a few hours for you guys to get them.

Yesterday the guys at Garmin Connect made some changes to their website. My app uses an "unofficial" integration, as access to the official Garmin API would require a 100x increase in sales to be economically sensible. Their update broke my integration.

I'm working on that. There were basically 4 issues to solve, and I've basically solved them all. I need more time to test the new version thoroughly.

- Please follow sportablet on facebook or twitter, or subscribe to the rss feed on this blog, or visit this blog periodically. I'm just one - I can either answer your emails or work on the app.

- If you send me an email, and while you're at it you ask me other questions about the app, please understand it's not the right time. I'm getting way too many emails when GC breaks down. Get in touch later on, thanks.

- Yeap, downrating the app in google play won't help a bit :-)

The Uploader for Garmin 5.0 and Sportablet 5.9 can now send tracks to some Garmin models (Forerunner 205, Forerunner 305, Edge 205, Edge 305), straight from your Android tablet / phone.

It's the first step of a long journey. All details here. 

Tell me what you think here, and don't forget to leave a positive review on google play, tell your friends, etc. The app needs you : ).

Lately, Endomondo has made changes to the upload workflow, breaking my apps. That was a know risk when I decided to support Endomondo, even though they do not officially support third party apps, which is why I said Endomondo support will be in permanent beta.

Anyway, after you guys told me yesterday night, I've modified my apps today, and I've just pushed a new version on Google Play. Sportablet 5.8 and the Uploader for Garmin 4.8 can upload to Endomondo again :-).

Today, Dynastream released version 4.01 (although they call it 4.1) of their ANT+ Radio Service, which I'm using in both Sportablet and the Uploader for Garmin as ANT+ transport layer. Like version 4.0 did, that release broke both my apps.

Sportablet 5.7 and the Uploader for Garmin 4.7 have been fixed to work with the new release of the Radio Service. However, while I managed to keep the previous version compatible with versions 2.x, 3.x and 4.0 of the Radio Service, this is proving too complex, and is causing every version of the Dynastream driver to break my apps. Therefore, beginning from this version, I'm only supporting the Dynastream ANT+ Radio Service version 4.01 (4.1). Of course, while I hope they won't break it again in the next release, I'll always do my best to update the app if anything happens.

Short story: if you get the new ANT+ service, you need the new app; if you get the new app, you need the new ANT+ service.

Sportablet 5.6 supports direct upload to RunningAHEAD. Data is sent in compressed form so to speed up the transfer; compression has also been added to the Uploader for Garmin, version 4.5. For details on uploading to RunningAHEAD, please see my previous post.

Guys, please take a moment to spread the news :-)

The Uploader for Garmin 4.4, just pushed to Google Play as I'm writing this, uploads directly to RunningAHEAD.

RunningAHEAD uses open authentication, so the first time you try to upload, you'll be redirected to runningahead.com, where you'll have to sign in and approve my app to access your training data. That should only be needed once.

Thanks to Eric @ RunningAHEAD for his support, and to Adam for his help gauging interest in the RunningAHEAD community.

Sportablet 5.5 and the Uploader for Garmin 4.3 support direct upload to SportTracks, so you don't need to export to SD card, log in, upload manually anymore.

Thanks to the guys at Zone Five Software for their support; really appreciated your extensions to the API. 

Thanks to Neil Catley as well, who has been the real catalyst here. Neil first put a video on youtube to help others upload manually, then asked for a more direct integration. That's the spirit :-).

Just like with Garmin Connect, at the end of the upload process the app shows an hyperlink, so that you can jump to the activity on sporttracks.mobi with one click (Uploader 4.4 and up, Sportablet 5.6 and up).

I've just pushed a new version of Sportablet to Google Play, with a direct upload option for Endomondo. This feature is going to be in permanent beta (see my previous post for details). 

Guys, please share this news with your Endomondo friends, thanks :-)

With some luck, next week I'll add one more direct upload option

The Uploader for Garmin, version 4.1, supports direct upload to Training Peaks. As usual, it may take a few hours before Google Play makes that version available to you guys. Of course, Sportablet will get this feature as well, though you may have to wait till Sunday (I've got a real job too :-).

Thanks to Training Peaks for their support, and to the ubiquitous DC Rainmaker who put us in contact.
