I've found your repo searching in google how yo hack waterrower S4. I've seen your code and it seems good and interesting.

But after searching how to update S4 firmware I've discovered this site:

There are some apps to achive the same goal. The only difference is that they do not use bluetooth.

Their software requires firmware 2.1 and to "upgrade" you need to pay $150 for a new S4. In my opinion a ripoff!
