Allow the app to record the video and to save file to the memory of the device
Select the right device in the main screen
Restart the app
Once restarted open peloton and start a workout
Using "nc -u -l 8003" on a PC or Mac you should see something like "100;70;30;19.9" where the first number is the power, the second the cadence, the 3rd the resistance and the last one the speed
The Peloton Bike+ tablet does respond to "input swipe 100 100 200 200 30" as a touch.
The command did not return an error.
While using the Peloton for Zwift I do not have a place on the screen to change resistance.
I can try a Peloton workout later and see if it shows up there, and I can load the Peloton app on my phone to see if that has any way to change the resistance.
