Rower profile not loading correctly?

[Sygaro]

First of all, I want to thank everyone who has developed and are contributing to develop and support ORM!

I have a Concept2 RowErg connected to an RPi 4B via an optocoupler as described. I am running ORM version 0.9.0.

Initially, I added the following to the config.js file:

rowerSettings: rowerProfiles.Concept2_RowErg

When testing, I noticed that the drag factor remains constant at 1500, and the power output is several thousand watts. It seems that config.js is unable to retrieve the correct rowing profile. Despite that I have set maxPower: 500 I get power output way above 500 watt. I have included the ANT settings in config.js, and it works which indicates that ORM is reading some of the settings in the config.js file.

I then tried to “force” the drag factor with the following, but with the same result:

rowerSettings: Object.assign(rowerProfiles.Concept2_RowErg, {
    dragFactor: 110,
    autoAdjustDragFactor: true
   }) 

I have also tried different variations of rowerSettings in the config.js file but with the same result.

rowerSettings: ‘rowerProfiles.Concept2_RowErg’

and

rowerSettings: Concept2_RowErg

And yes, I have restarted the ORM between every changes to the config.js file

What am I doing wrong?

Attached are the config.js file and a test session.

your config is invalid:

   rowerSettings: rowerProfiles.Concept2_RowErg
   rowerSettings: Object.assign(rowerProfiles.Concept2_RowErg, {
    dragFactor: 110,
    autoAdjustDragFactor: true
   })

Also you are missing comas.

Min power and max power is only for the UI

Use the below (copy paste)

"use strict";

	// The rower specific settings. Either choose a profile from config/rowerProfiles.js (see

	// on how to do this). If you find good settings for a new rowing device please send them to us (together
	// with a raw recording of at least 10 strokes) so we can add the device to the profiles.

	// EXAMPLE ROWER CONFIG : using a DKN R-320 Air Rower as is
	// rowerSettings: rowerProfiles.DKN_R320

	rowerSettings: rowerProfiles.Concept2_RowErg,

	// EXAMPLE ROWER CONFIG: Just set custom rower settings to make it work
	// rowerSettings: {
	//   numOfImpulsesPerRevolution: 1,
	//   dragFactor: 0.03,
	//   flywheelInertia: 0.3
	// }

	// EXAMPLE ROWER CONFIG: set a rower profile, but overwrite some settings:
	// rowerSettings: Object.assign(rowerProfiles.DKN_R320, {
	//   autoAdjustDragFactor: true
	// })
	userSettings: {
		// The resting Heartrate of the user, to filter abnomral HR values

		// This is used for filtering abnormal HR values and to project the maximum power a rower produces
		maxHR: 190,

		// The minimum power a rower can produce, used for filtering abnormal power values
		minPower: 50,

		// The maximum power a rower can produce, used for filtering abnormal power values
		maxPower: 500,

		// The effect that doubling the distance has on the maximum achievable average pace. The proposed 5 is based on Paul's law,
		// which states that doubling the distance leads to a slowdown in pace of 5 seconds. This value can be adapted if you know
		// your PR (this pace) on both a 1000 meters and on 2000 meters, by substracting the pace.
		distanceCorrectionFactor: 5,

		// The weight of the rower in kilograms
		weight: 68,

		// The sex of the rower, as it is needed for Concept 2's calculation
		// This can be "male" or "female"
		sex: "male",

		// If you have been rowing regularly for several years, training at least four days per week, doing a variety of workout types

Thank you for figuring out the problem :)

I noticed that I made this post under the "old" ORM project. I therefor closed this post and made a new post under the current ORM project:

[https://github.com/JaapvanEkris/discussions/75]

The config.js file you made for me is working now, but now I'm experience some other issues. I will continue the discussion in the post I linked to above, I hope that you can take some time and take a look at the "new" issues I have.
