Lelo Ida Wave

Introduction

The Lelo Ida Wave is a BLE-controlled couples' vibrator with both vibration and internal "waving" motion motors. It uses a pairing procedure shared with the Lelo F1s v2.

Pairing

The Ida Wave uses the same pairing strategy as the Lelo F1s v2:

1. On power-on, the device advertises itself
2. Read from 0x0a11 — if the response is 1, the device is already paired
3. If a previously stored passphrase exists, write it to 0x0a11, then read back — if 1, pairing is restored
4. If the response is 0, subscription-based pairing is needed:
   • Subscribe to notifications on 0x0a11
   • The user must press the power button on the device
   • On button press, a passphrase is sent via notification on 0x0a11
   • Write the received passphrase back to 0x0a11
   • The device should then respond with 1 (paired)

Commands

Stop All

Stops all motors.

Write to 0xFFF2:

0x0A 0x01

Motor Control

Controls the vibration and internal wave motors independently.

Write to 0xFFF2:

0x0A 0x12 MM 0x08 0x00 0x00 0x00 0x00 HH LL

Byte	Description	Range
0x0A	Command prefix	Fixed
0x12	Motor control command	Fixed
MM	Motor select	0x01 = external vibe, 0x02 = internal wiggler
0x08	Unknown	Fixed
0x00 0x00 0x00 0x00	Unknown padding	Fixed
HH	Max speed	0x00-0x64
LL	Min speed	0x00-0x64

Examples:

• Stop everything: 0x0A 0x01
• External vibe at full speed: 0x0A 0x12 0x01 0x08 0x00 0x00 0x00 0x00 0x64 0x00
• Internal wiggler at full speed: 0x0A 0x12 0x02 0x08 0x00 0x00 0x00 0x00 0x64 0x00

Notes

• No Buttplug implementation exists yet.
• No device-config YAML exists yet.
• The pairing procedure is shared with the Lelo F1s v2.
• Motor select value 0x01 controls the external vibration motor, 0x02 controls the internal waving/wiggling motor.
