Introduction
kdri
is a library that lets you control Kettler devices via
bluetooth. This includes following models:
- TOUR
- RACER
- ERGO
- RECUMBENT
- UNIX
- SKYLON
- RUN
- TRACK
This library is tested on a RUN 7
. Because there are no platform independent
bluetooth libraries for Rust (yet), it only runs on BlueZ/Linux.
Example
extern crate kdri;
use std::io::Write;
use std::str::FromStr;
fn main() {
println!("Search for devices...");
// Scan for all Kettler devices in range. This function will block for some seconds.
let mut devices = kdri::scan_devices().expect("Scanning devices failed");
// Ignore all other devices, just use the last one.
let device: kdri::KettlerDevice = devices.pop().expect("No devices found");
// Connect to Kettler device. This function blocks for about 1-2 seconds.
println!("Connect to \"{}\" (\"{}\")...", device.get_name(), device.get_addr().to_string());
let mut connection = device.connect().expect("Connecting to Kettler device failed");
println!("Connected!");
loop {
// shell-like IO
print!("> ");
std::io::stdout().flush().unwrap();
let mut input = String::new();
std::io::stdin().read_line(&mut input).unwrap();
input = input.trim().to_string();
match input.as_str() {
"exit" => { break },
/* Fetching values via "KettlerConnection.get_*()". The return value is a Option<u8>, Option<u16> or Option<SomeSpecificEnum>. A
None value means, that the value isn't initialized (yet). This will happen for example if you try "get_rpm()" on a treadmill.
Values like speed and incline are in multiplied by 10. "get_speed() = Some(105)" means "10.5km/h". */
"pulse" => { println!("pulse: {:?}", connection.get_pulse());},
"speed" => { println!("speed: {:?}", connection.get_speed());},
"incline" => { println!("incline: {:?}", connection.get_incline());},
_ => {
// parse commands like "speed=100" or "incline=20"
let substring: Vec<_> = input.split('=').collect();
if substring.len() != 2 { println!("Input not recognized"); continue; }
let number: i32 = match FromStr::from_str(substring[1]) { Ok(n) => n, Err(_) => { println!("Expected number after '='"); continue; } };
match substring[0] {
"online" => connection.set_online(number != 0), // "online=0" stops the device (tested on treadmill)
"speed" => connection.set_speed(number as u16), // values are divided by 10 -> "50" means "5km/h"
"incline" => connection.set_incline(number as u16),
_ => println!("Unknown value '{}'", substring[0]),
}
}
}
}
// close connection
connection.close();
}
