Quick and dirty Go CLI for the Sportstech DFT200 standing desk treadmill.
Requires a running bluetoothd and Go 1.11+.
Inspired by https://github.com/machinekoder/deskfit.

Using a treadmill is dangerous. A few notes by a fellow DFT200 owner:
-
The Bluetooth feature is unauthenticated. Anyone in range can control your treadmill.
-
I haven't figured out the right command for emergency stop, and I found no references while reverse engineering the Android application. Always keep the hardware remote control close to you, especially at higher speeds - pressing the start button twice will trigger an emergency stop.
-
Be careful when playing with the Bluetooth interface, you might brick your treadmill. There are commands for reading and (presumably) writing the EEPROM.
-
Do not install the Android application - it requests tons of dangerous permissions for no good reason, and at least one variant of it is packed by a APK packer commonly used by malware. The DFT200 manual recommends to install the APK from their website, which is generally a bad idea™.
Install bluetoothd via your distro package manager and start it:
systemctl enable bluetooth.service
systemctl start bluetooth.service
Find MAC address using bluetoothctl:
scan on
devices
connect <mac>
Alternatively, you can use a bluetoothd GUI like Gnome's native applet, blueberry (GTK) or bluedevil (KDE).
Install to $GOPATH/bin:
go install github.com/leoluk/dft200-go/cmd/dft-cli
Start treadmill (or continue, if paused):
dft-cli -addr <mac> -start
Pause treadmill:
dft-cli -addr <mac> -pause
Stop treadmill (you don't usually need this, it will stop after you leave it paused for a few minutes):
dft-cli -addr <mac> -stop
Set speed (10-80 for levels 1-8):
dft-cli -addr <mac> -speed <n>
set $tmMac <mac>
