Lovense

Introduction

Lovense has been manufacturing toys since 2011.

Bluetooth Details

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

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 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 different toy firmware versions.

Protocol

Commands for Lovense toys follows these 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.
