- Read Serial Waterrower Data to the Pi
- Read SmartRow data to the Pi via bluetooth (for pi 3,4 and Zero W internal bluetooth + USB Bluetooth dongle needed - for pi 1,2,3 without internal bluetooth 2 USB bluetooth dongle from different brands are needed)
- Send Waterrower Data from the Pi over Bluetooth (Build-in or USB-dongle)
- Send Waterrower Data from the Pi over Ant+ via Ant+ dongle
I wanted to have the ability to use the Android App Coxswain and also my Garmin smartwatch. Therefore, I though why not connect the Waterrower via USB to a Raspberry pi and let the Raspberry pi being a BLE and Ant+ transmitter. And wouldn't be even better if it could be control for the Webbrowser. And Last but not least, have at the end of the training a FIT file for Garmin connect or Strava.
With a high demand from people having the Smartrow, I thought why not trying to integrate it as input interface for this project. So it would be either S4 Monitor or Smartrow

I would recommend buying the Raspberry pi in a kit where most of the parts are included
On a fresh installed Raspbian, git must be installed first
sudo apt-get install git
Clone the repo from Github:
git clone https://github.com/inonoob/pirowflo.git
go into the folder:
cd pirowflo
make install.sh executable:
sudo chmod +x install.sh
execute install.sh in order to setup everything: (This can take 5 - 10 min to set all up). If during the first installation you hadn't have your Ant+ dongle. Just re-run the script and it will install the missing Ant+ and udev profiles.
sudo ./install.sh
Once installation and reboot complete, go into the pirowflo/src folder
cd /home/pi/pirowflo/src
Start PiRowFlo from the webserver which is available under the:
http://"raspberry-pi-IP":9001
or
Use the Screen to start PiRowFlo
or
start PiRowFlo from console
If the script waterrowerthreads is started with -h or --help it shows the available option for the program
python3 waterrowerthreads.py -h
usage: waterrowerthreads.py [-h] [-i {s4,sr}] [-b] [-a]
Python script to broadcast waterrower data over BLE and ANT

To begin choose an interface from where the data will be taken from either the
S4 Monitor connected via USB or the smartrow pulley via bluetooth low energy
Then select which broadcast methode will be used. Bluetooth low energy or Ant+ or both.
e.g. use the S4 connected via USB and broadcast data over bluetooth and Ant+
python3 waterrowerthreads.py -i s4 -b -a
optional arguments:
-h, --help show this help message and exit
-i {s4,sr}, --interface {s4,sr}
choose Waterrower interface S4 monitor: s4 or Smartrow: sr
-b, --blue Broadcast Waterrower data over bluetooth low energy
-a, --antfe Broadcast Waterrower data over Ant+
For example if the Waterrower should send data over Bluetooth and ANT
python3 waterrowerthreads.py -i s4 -b -a
The PiRowFlo autoupdate function is not yet implemented. Therefore, we recommend to perform the update as follows:
git pull https://github.com/inonoob/pirowflo.git
And then start the installation script again
sudo ./install.sh
I got the error:
serial open error waiting
if that is the case, check if your $USER belongs to the group "dialout"
pi@raspberrypi:/dev $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi
if you don't see the "dialout", then your $USER needs to be add to this group
sudo usermod -a -G dialout $USER
Then you need to log out or reboot that it takes effect.
I can't connect with the app Coxswain:
It is only working with Coxswain version higher 7.9. as the low version haven't the improved connectivity code for bluetooth.
If you see this kind of error in the console you

That means what a client is still connect with the Raspberry pi and must be disconnect first before restarting the service. So check on your smartphone or tablet is a connection is still active. The simplest thing to fix is to close the app and then try again.
if you see this kind of error in the console:

Exception in thread Thread-4:
that means that the current user is not in the group "bluetooth". The used to be a bug in the install.sh. But you can also add it manually with the following command:
sudo usermod -a -G bluetooth pi
This command run as sudo will add the user "pi" to the group "bluetooth". Then reboot in order to take effect. This should fix the issue.
In order to check if it had worked, use the following command:
pi@raspberrypi:~/pirowflo $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev bluetooth gpio i2c spi
If you can connect to the PI with your third party app and don't get any data also don't get any data to your watch via ant+ then there is a high chance that the connection between S4 Monitor and the Rasbperry pi is not working correctly.
- Check if you have heard the reset "BEEP" from the S4 Monitor. If not that means that the connection is not correct try to unplug and replug it in.
- Check the usb cable first. Try a different one. Cheap one tend to break as you need to plug and unplug it.
- Link to repo base code used to get the Waterrower Data over USB Interface
- Link to repo base code for the BLE GATT server and Advertiser example which is self based on the Bluez Gatt server example
- Link to repo base code for the Ant+ part used for this project
- Link to repo base code for the Screen part used for this project
Those Repos with some of their code are used as base code which then have been rewritten to meet the requirements of this project.
