Lovense Hardware and Protocol Documentation

Models

Each Lovense toy is identifiable by a Model Number assigned to the toy. This model number is used in bluetooth discovery, as well as in libraries to discern toy capabilities.

Name Form Factor Model Capabilities
Nora Rabbit Vibe A or C Vibration, Rotation, Accelerometer
Max Onahole B Vibration, Inflation, Accelerometer
Lush Vaginal Insertable Vibe S Vibration
Hush Buttplug Z Vibration
Edge Prostate Stimulator Unknown Vibration
Ambi Bullet Vibe Unknown Vibration
Domi Magic Wand Style Vibe Unknown Vibration
Osci G-Spot Vibrator Unknown Vibration

Bluetooth Details

While all lovense toys use the same protocol, they can communicate over bluetooth differently, depending on when they were released.

When discovering or pairing with Lovense toys, toys identify using the format “LVS-?001”. The ? will be a letter pertaining to the model specifier. For instance, when discovering the Hush Buttplug, it will show up as “LVS-Z001”, as “Z” is the model code for the Hush.

Bluetooth 2.0 Toys

The first toys released by Lovense used both Bluetooth 2.0 SPP (emulating a serial port) and Bluetooth LE. This was most likely due to the sparse mobile support of BTLE when they were released.

These toys include:

  • Max
  • Nora

When paired with a system via Bluetooth 2.0, these toys identify as a serial port. These toys are also capable of using Bluetooth 4.0, as outlined in the next section.

Bluetooth LE Toys

Starting with the Lush, all toys released by Lovense use only Bluetooth LE.

These toys include:

  • Lush
  • Hush
  • Edge
  • Ambi
  • Osci
  • Domi

These toys have GATT characteristics to mimic the RX/TX setup of the serial port style control of the old toys. The GATT service and characteristic IDs differ between the Max/Nora and all toys released afterward.

Service UUID (Max/Nora):

0000fff0-0000-1000-8000-00805f9b34fb

TX Characteristic UUID (Max/Nora):

0000fff1-0000-1000-8000-00805f9b34fb

TX Characteristic UUID (Max/Nora):

0000fff2-0000-1000-8000-00805f9b34fb

Service UUID (All Others):

6e400001-b5a3-f393-e0a9-e50e24dcca9e

TX Characteristic UUID (All Others):

6e400002-b5a3-f393-e0a9-e50e24dcca9e

RX Characteristic UUID (All Others):

6e400003-b5a3-f393-e0a9-e50e24dcca9e

Lovense Protocol

Protocol Rules

  • Commands and replies are strings, using semicolons to mark their end.
  • All commands start with a command identifier word, then possibly either specifiers or levels, delimited by colons. e.g. “Vibrate:5;” would set vibration to 5.
  • Replies are in the context of the command (i.e. sending “Battery;” will just return a number, like “85;”), but can still be colon delimited lists.
  • Commands that do not return a context specific value will return “OK;” on success, “ERR;” on error.

Command List

The following is the known command table for all toys. Anything send or received over the serial port is in quotes to denote communication, but should not be sent using quotes if you are implementing your own version of this protocol. Commands with ”:x” mean that the x should be replaced with a number, the range of which is mentioned in the description.

This document contains information about Lovense sex toy hardware, and the common bluetooth protocol used in all Lovense toys. This information can be used to access Lovense toys and create new libraries for controlling features and receiving information from them.

Lovense Library Info

lovesense is a library for controlling Lovense sex toys. The library allows users to control all aspects of the toy (vibration/rotation/inflation, depending on the toy), as well as retrieving information like device type, status, battery level, and accelerometer readings.

The library is currently available in the following languages:

If you need an implementation in a language not currently supported by lovesense, please file an issue on the github tracker of the lovesense-docs projects

Please note that this project has no direct relation to the Lovense company. These drivers have been developed/supported by the open source community. Lovense has had no direct participation in this project and most likely will not be able to answer questions or provide support for any of the Lovesense drivers.

If you require commercial support for programming for Lovense products, it is recommended you go through the Official Lovense Developer Program.
