Use FortiusANT with "Raspberry Pi Zero" about fortiusant HOT 12 CLOSED

I try to understand what you want to achieve, but cannot figure it out.
To understand, please explain what a "Raspberry Pi Zero" is.

I created wiki page Fortius ANT Configurations and perhaps that gives a hint to draw what configuration you want to achieve.

The 4th configuration (with the independant HRM strap) is an option I'm building these days.
The -H flag makes FortiusANT to listen to an ANT+ master device (a heart rate monitor strap) to pick up the heartrate when the Tacx Fortius does not supply it, in the case you would use a new ANT+ HRM that is not recognized by the Tacx Fortius. This is not essential, but makes the heartbeat display work again.

In case somebody would use a bicycle with a power-meter and cadence sensor, need would arise for a -P and -C flag, so that FortiusANT would pick it up (listen to ANT+ master devices) and send it as one integrated ANT+ FE-C master device to the training software (Trainer Road, Zwift).
This would only be usefull, if you have a trainer brake without power/cadence sensor, integrate them with the independant devices as one ANT+ FE-C device.

As stated above, an explanation what you want to achieve would be helpfull; To answer your question, I think that adding options to GetTrainer() would NOT be usefull, since that is the USB-interface to Tacx Fortius

What device do you connect?

Also, are you on Strava? Would like to see FortiusANT results :-)

Raspberry Pi Zero (5 euro) is a open source single board computer running Linux with a very small form factor.

Sure, but I'm curious how this relates to FortiusANT and/or Controllable Fitness Equipment :-)

It can be a cheap platform for ‘converting’ the USB to ANT+ connection. It could run headless and be ‘integrated’

I guessed something like this was going on.

New to ANT+? I hope you are familiar with www.thisisant.com and
D00001163_-_ANT+Device_Profile-_Bicycle_Speed_and_Cadence_2.1.pdf?
It took me a while to get from the antifier source to that documentation, so ask the dumb question.

If you want to use FortiusANT and read data from cadense/speed sensor:

• in antDongle.py add channel_CSC as a unique channel ID
• in FortiusAnt.py Tacx2Dongle()
  -- open a slave channel to the sensor
  -- expect messages from the sensor (add elif Channel == ant.channel_CSC:) where all incoming messages are handled
  -- handle message 0 (default page) with a msgUnpage0_CombinedSpeedCadence(info) function according the information at page 44 returning BikeCadenceEventTime, CumulativeCadenceRevolutionCount, BikeSpeedEventTime, CumulativeSpeedRevolutionCount

I have created an ExplorANT program to check what dongles are in my computer, what devices are on the network and what happens on the devices. I will publish shortly, after doing some final tests.
I expect this to be helpful for you since it provides a template to create slave devices, listening to master devices; where the BikeCadenceSensor is the one to be implemented by you.

Like to hear from you and your achievements.

Alana, new version upload with SCS code example added. Check antDongle.py and FortiusANT.py for "scs". Tested with https://www.strava.com/activities/3088842976

If more info needed, please reopen the issue or create a new one.

@Alanimus you will like to see the RPI developments!
