ergoFACE

forked from https://github.com/360manu/kettlerUSB2BLE
adjusted to work with Daum ergobike 8008TRS

the original project "ergoFACE concept"

can be found here https://github.com/weinzmi/ergoFACE

prerequisites

RS232 to USB converter
RS232 custom gender changer or "programing cable" like specified from DAUM
raspberry pi zero w / 3B+ with BLE (Bluetooth low energy) onboard
nodejs (10.xx.x LTS) installed https://nodejs.org/en/

setup - Install on a rasperypi

download the sources / dependencies listed in package.json
have a look at bleno setup https://github.com/noble/bleno

npm install

it can take a while as bleno must be compiled from sources.

launch

if SIM mode is a feature you want to use, edit the parameters in config.yml to fit yours


simulation:
maxGrade: 16 // maximum grade, higher than this, will be cut
mRider: 78 // weight of you, the rider
mBike: 9 // weight of your bike

gearbox: // this are the gear ratios used for each gear g1: 1.36 g2: 1.48 g3: 1.62 g4: 1.79 g5: 2.00 g6: 2.17 g7: 2.38 g8: 2.63 g9: 2.94 g10: 3.33 g11: 3.57 g12: 3.85 g13: 4.17 g14: 4.55


## GIOPs for shifting gears
* if you want to use 2 external buttons for shifting gears, edit the parameters in config.yml to fit yours

gpio: geargpio: 1 // start gear for initializing ratio: 1 // how many gears are shifted with one push of a button minGear: 1 // lowest gear possible maxGear: 14 // highest gear possible; has to match gearbox debounceTimeout: 10 shiftUpPin: 4 // GPIO pin for shift up shiftDownPin: 17 // GPIO pin for shift down


* go to installation directory and start node server from command line
```shell
sudo node server.js

you can install the server as a service, to just plug the raspberry to a power source and ride on

copy ergoFACE.service from lib\systemd\system to your local system (this is an example for Raspbian Stretch)
```
sudo chmod 644 /lib/systemd/system/ergoFACE.service
```

configure

sudo systemctl daemon-reload
sudo systemctl enable ergoFACE.service

reboot
```
sudo reboot
```
check status of service
```
sudo systemctl status ergoFACE.service
```
plug the RS232 to USB converter in any USB port
start your Daum ergobike 8008 TRS
ergoFACE will lookup for the cockpit address and start receiving data
start an app like ZWIFT and your Daum bike will appear as "DAUM Ergobike 8008 TRS" device with two services (power & FTMS)

website / server

start your browser and enter "pi-adress:3000" (try to get fixed IP address for you raspberry on your router before) you can follow the ergoFACE activity on a this website. It will display the current power, rpm, speed the current gear and program your Daum is running and the socket messages. This site is used to toggle between ERG and SIM mode and toggle between switching gears or just power
you can use the server to:
see current data from Daum Ergobike
see power calculation (simulation), grade (slope), Cw (aerodynamic drag coefficient)
see current program & gear
stop / restart RS232 interface via server
select gears
select program
toggle set Power / switch gears
toggle socket messages - key / raw / error

current features 0.6.4 BETA

common

advanced webserver with dashboard and log messages based on Bootstrap v4.1.3
apps recognize BLE (Bluetooth low energy) GATT FTM (Fitness machine) and CPC (Cycling power and cadence) service
in ZWIFT
ERG mode is fully implemented (FTMS control point), can be switched in workouts via ZWIFT app.
SIM mode is fully implemented (FTMS control point) and physics simulation based on parameters send from ZWIFT and parameters input by the user - see section "launch"
use virtual gearbox and use Daum buttons and jog wheel to switch gears
use gpios (see gpio.js) to add hardware switches for more realistic ride and shifting experience, if not, use the jog wheel or +/- buttons on Daum ergobike 8008 TRS

tested apps

FULL GAZ - SIM mode working; no rpm
ZWIFT - ERG mode working; SIM mode working; all signals working

outlook / features to be developed

start NodeJS server and raspberry in access point / hotspot mode to connect via mobile device and scan for your local Wi-Fi and enter credentials
scan for updates via server and select ergoFACE versions, download and reboot
