Today I have the new Research and Desire wireless remote, also called the RADR. And I’m super excited to show you how it connects with both OSSM and also a wireless Bluetooth device like the Domi right here. In order to control the OSSM, you have to make sure that you have updated your firmware to the newest version. Once you’ve done that, just make sure that your machine is plugged in and turned on. And I’ll show you how it connects really quickly. I’m turning on the power switch. And as you can see, it is automatically searching for the device and voila, it is connected. You don’t have to do anything else.I’ll go over some of the specifics of the remote now. The left-hand knob always controls speed and the right-hand knob toggles and adjusts depth, sensation, and stroke. I’m going to turn up the speed a little bit here so you can see that’s going. Right now I’m in Stroke; as I move the Stroke knob, you can see one of the rings go up and down, so you can always see where you’re at in terms of how much stroke you have on.The buttons: this button here is Pattern. If you click into it, you’ll be able to take a look at all the different patterns and you can select one using the Pattern button again. This button here is stop and go—pause or play. There we go, it stopped the OSSM immediately; click it again and the device is stopped. Once it stops you can just turn up the speed again and it’ll start working again. And that’s it for controlling the OSSM.I also want to show you how to control the Domi. I’m going to turn off the OSSM and unplug it. Now I’ve got my Domi; I’ll turn it on and do the same thing as with the OSSM. I turn on the RADR and it automatically searches for the device. And look at that—it connects to my Domi. I can play with the knob, and there’s that stop button as well. There you have it: the wireless RADR connecting to both the Domi and the OSSM.
RADR started as a wireless, user‑friendly controller for the OSSM (Open‑Source Sex Machine), created in partnership with The Kinkymakers. It has since evolved into a versatile wireless controller for a range of Bluetooth‑enabled devices using the Buttplug.io protocol. This guide helps you pair your RADR with the OSSM and get playing in minutes. The same process applies to other supported devices like the Lovense Domi 2.

​
Getting started

​
Prerequisites

  • RADR charged (USB‑C)
  • Supported device powered on nearby (OSSM, Lovense Domi 2, etc.)
  • OSSM firmware version 2.0.0 or later
  • No other apps or controllers currently connected to the Bluetooth device
RADR only connects to supported devices. See Device support for details.

​
Remote layout

RADR remote layout: screen, three buttons, left/right knobs, and bumpers
The RADR provides tactile, glanceable controls you can operate without looking away.
  • Top edge
    • Left bumper — mode previous
    • Power switch — above the screen, to the left of the USB‑C port
    • Right bumper — mode next
  • Front face
    • Full‑color LCD centered on the device
    • Three buttons below the screen
      • Left button — Home / Back
      • Middle button — Pause / Stop
      • Right button — Menu / OK
  • Sides
    • Left knob (encoder) — Speed
    • Right knob (encoder) — Depth, Sensation, or Stroke (based on the current mode)

​
Powering on

1

Charge your RADR

Connect RADR to a power source with a USB‑C cable and allow it to charge.
RADR turns on and the battery icon appears on screen.
2

Turn on RADR

Flip the power switch to the right (toward the USB‑C port).
RADR automatically scans for nearby supported Bluetooth devices.
3

Prepare your device

  • For OSSM: Power it on and let it finish homing.
  • For other devices (e.g., Lovense Domi 2): Power on and ensure no phone app is connected.
Only one controller/app can be connected to a Bluetooth device at a time. Close vendor apps (e.g., Lovense) before pairing with RADR.

Check which devices are compatible with RADR.

​
Pairing with the OSSM

1

Update your OSSM firmware

Ensure your OSSM is running firmware 2.0.0 or higher.

Flashing your OSSM

Follow our firmware update guide if you need to update your OSSM.
2

Power on and home the OSSM

Turn on your OSSM and allow it to complete its homing routine. Keep it powered on.
3

Scan for devices

RADR automatically scans for nearby Bluetooth devices for 5 seconds when powered on. A blue LED pulses during the search.
You can also start a manual scan from the main menu by selecting Device Search.
4

Select your device

After scanning, RADR displays a list of discovered devices. Use the right knob to scroll through the list, then press the right button to connect to your OSSM.
Connection status messages appear: “Connecting…”, “Connected! Setting up device…”, and finally “Device ready!”
5

Start playing

The Play Controls screen appears once connected. The middle LED turns white to indicate an active connection.
You can now control your OSSM using the knobs, bumpers, and buttons.

​
Play controls

When RADR is paired, you’ll see the Play Controls screen.

ControlAction
Left knobAdjust speed (0–100%)
Right knobAdjust the active mode (Depth, Sensation, or Stroke)
Left/Right bumperCycle through adjustment modes
Left buttonReserved for future device settings (currently disabled)
Middle buttonSingle press: Pause — sets speed to 0, displays red “Paused” text, middle LED turns red. Double press: Full Stop — resets Depth to 0%, Stroke to 10%, Sensation to 50%
Right buttonOpen Pattern Mode
Use the bumpers to switch modes without looking down. The on‑screen tabs show which mode is active: Depth, Sensation, or Stroke.
When paused, increase the speed with the left knob to resume playback automatically. The middle LED returns to white when active.

​

New patterns are added over time. Check for firmware updates to access the latest libraries.

​
Sleep mode

To conserve battery when not in use, RADR offers a deep sleep mode accessible from the main menu.
1

Access the main menu

From the Play Controls screen, press the left button to return to the main menu (when paused) or disconnect your device first.
2

Select Sleep

Navigate to Sleep using the right knob and press the right button. RADR plays a shutdown sound, turns off the display, and enters deep sleep.
3

Wake up

Press any of the three under-screen buttons to wake RADR. The device restarts and returns to the main menu.

​
Connection recovery

If RADR loses connection—due to distance, power loss, or Bluetooth interference—it automatically attempts to reconnect within 2–5 seconds.
If reconnection doesn’t happen quickly, OSSM gradually ramps down and pauses for safety.
If reconnection fails, power‑cycle both the RADR and your device. They will pair automatically on restart.

​
Power saving

To extend battery life, RADR automatically dims the screen after 30 seconds of inactivity. After 2 minutes without interaction, the screen enters a deeper power-saving mode, and after 10 minutes of inactivity, the screen turns off completely. Any button press or encoder rotation will instantly restore the screen to full brightness.

​
Troubleshooting

  • Ensure the device is powered on and charged
  • Move within 1–2 meters for initial pairing
  • Close vendor phone apps (Lovense, etc.) so RADR can take the connection
  • Power‑cycle RADR and the device, then retry
  • For OSSM, confirm firmware ≥ 2.0.0
  • Increase speed with the left knob to resume from Pause
  • If you double‑pressed Stop, defaults are restored—re‑set your mode and adjustments
  • Verify the OSSM completed homing and is not physically obstructed
  • Ensure speed is set above 0
  • Select a pattern with the right button (Menu/OK)
  • Exit Pattern Mode (left button) and re‑enter if the screen appears unresponsive
  • Reduce interference: move away from Wi‑Fi routers and metal surfaces
  • Keep phone apps closed to prevent connection stealing
  • Update firmware on both RADR and your device when updates are available
If the left (speed) or right (depth/sensation/stroke) encoder knob doesn’t respond, responds intermittently, or makes large unpredictable jumps in value:
  1. Update firmware — Flash the latest firmware to both RADR and your device using the Web Flasher
  2. Power-cycle — Turn RADR off and on again
  3. Test both knobs — Determine if the issue affects one knob, both knobs, or alternates between them
If the problem persists after updating firmware, this indicates a hardware defect with the encoder component. Contact support for a replacement.
