How to connect MK-312BT to funscripts

Buttplug.io via Intiface Central

  1. Install Intiface Central (the free Buttplug.io hub app) on your computer and start its server.
  2. Connect the MK-312BT (plug it in or pair it) and let Intiface Central detect it.
  3. In HaptiQ open Devices → Advanced → Use the Intiface Central app, and connect to your Intiface server (ws://localhost:12345 by default).
  4. Load a funscript or generate one from a video and press play — HaptiQ routes every scripted action through Intiface to the device.

On iPhone or iPad, browsers block Bluetooth: use the free Bluefy browser today, or the HaptiQ iPhone app launching in October. Full MK-312BT setup and troubleshooting guide.

Frequently asked questions

Does the MK-312BT work with funscripts?

Yes. A funscript is a device-agnostic motion file, so the same script plays on any supported hardware. HaptiQ converts the motion in a video into a funscript and streams it to your MK-312BT in time with playback.

How does the MK-312BT connect to HaptiQ?

The MK-312BT connects over a wired USB connection. Browsers cannot open a raw serial port to a toy without a bridge, so run Intiface Central (Buttplug.io) on the same machine and HaptiQ will drive the device through it. This is desktop only.

Do I need Intiface or Buttplug.io for the MK-312BT?

Yes. Because the MK-312BT connects via BT2 (Serial) or Serial or Audio, a browser cannot reach it directly. Install Intiface Central, connect the device there, and HaptiQ will drive it through Buttplug.io.

Which browsers support the MK-312BT?

Use any modern browser on a desktop machine. The USB link is handled by Intiface Central, so browser choice does not matter.

Can I generate a funscript for the MK-312BT from my own video?

Yes. Upload a video or paste a link, and HaptiQ's motion analysis produces a .funscript you can play on the MK-312BT or export for another player. Large files are uploaded in parts, so multi-gigabyte VR video is supported.

What kind of device is the MK-312BT?

The MK-312BT is an estim machine. HaptiQ maps the vertical motion in a funscript onto whatever actuation the estim machine provides, so scripts written for other hardware still play.
