Can you stream and record cycling data such as power and cadence from Garmin TACX trainer using ANT+ dongle?

Hi,

I have googled it, but I am still unsure what toolbox I need and if it is feasible. I am looking for a way to stream and record cycling data measured by Garmin TACX trainer using ANT+ dongle. Also, I was wondering if the target power output can be controlled in MATLAB as well. Any advice and suggestions are appreciated.

It's https://www.mathworks.com/products/instrument.html -> Instrument Control Toolbox.

However, you'll need to use the appropriate hardware and toolboxes to interface with the ANT+ protocol.

The specific code will depend on the ANT+ MATLAB library you choose to use. However, here's a basic example using the ANT-MATLAB library:

% Connect to the ANT+ dongle
ant = AntManager.instance();

% Open the ANT+ connection
ant.open();

% Subscribe to the power and cadence channels
powerChannel = ant.subscribeToChannel(ChannelType.Power);
cadenceChannel = ant.subscribeToChannel(ChannelType.Cadence);

% Continuously read and record the data
while true
    powerData = powerChannel.readBroadcast();
    cadenceData = cadenceChannel.readBroadcast();
    
    % Process and record the data as needed
    % ...
end

% Close the ANT+ connection when done
ant.close();

Thanks, if it helps let me know.

Thank you for your help! I will try it when I get the toolbox and dongle.

Great.

@Manikanta Aditya Now, I finally have a chance to try your suggestions, but the code you provided did not work. The first line of the code does not connect to the ANT+ dongle and Matlab displayed "Unable to resolve the name 'AntManager.instance'." Could you please let me know a little bit more detailed way to connect ANT dongle and read the data to the computer? Thank you for your help.

"However, you'll need to use the appropriate hardware and toolboxes to interface with the ANT+ protocol." As mentioned earlier.

Even I am not exactly sure for the answer to your query, maybe try contacting MathWorks Technical support: https://in.mathworks.com/support/contact_us.html

Thanks.
