Controlling a Lovense Edge over Bluetooth using Python

Thanks to the details provided over at https://stpihkal.docs.buttplug.io/ I was able to figure out how to directly control the Lovense Edge using Python. It was a bit tricky finding a workable Python library but I found a solution.

Requirements:

Python 3.8 or higher
Bluetooth interface
Bleak package
A Lovense Edge device

I still don’t fully understand the BLE control structure but I was able to cobble together the following code that will control the Edge.

# -*- coding: utf-8 -*-

import asyncio
import platform
import bleak
 
from time import sleep
from bleak import BleakClient
from bleak import _logger as logger
 
 
DEVICE_ADDRESS = '78211627-1BCD-4$05-AEBB-2222815AA2676'
DEVICE_WRITE_UUID = '50300002-0023-4bd4-bbd5-a6920e4c5653'
 
 
async def run(device_uuid_address, debug=False):
 
    async def set_vibration(client, vibrator, intensity, duration):
        await client.write_gatt_char(
            DEVICE_WRITE_UUID, 
            vibration_command_byte_string(vibrator, intensity), True
        )
        #await asyncio.sleep(duration)
        sleep(duration)
 
    async with BleakClient(device_uuid_address) as client:
        try:
            x = await client.is_connected()
            logger.info("Connected: {0}".format(x))
        except bleak.exc.BleakError as e:
            print(e)
 
        await set_vibration(client=client, vibrator=1, intensity=0.99, duration=10)
 
 
def vibration_command_byte_string(vibrator, intensity):
    intensity = int(intensity*20)
    return_string = f'Vibrate{vibrator}:{intensity};'
     
    return str.encode(return_string)
 
 
if __name__ == "__main__":
 
    device_uuid_address = (
        "21:70:84:aa:04:09"
        if platform.system() != "Darwin"
        else DEVICE_ADDRESS
    )
 
    loop = asyncio.get_event_loop()
    loop.run_until_complete(run(device_uuid_address, True))

Notes:

This code was only tested on OSX, so YMMV. Bleak is cross platform so I think it should work on Windows as well.
You will need to input the MAC address and DEVICE ADDRESS for your Edge device on lines 14 and 48.
The Edge is controlled by the command on line 35. The variables work as follows:
- vibrator: can be either 1 or 2
- intensity: a value between 0 and 1, with 0 being off and 1 being maximum power.
- duration: how long you want the Edge to run with those settings.
Just duplicate line 35 to add different instructions.

I will do another post on how to find your MAC address and DEVICE_ADDRESS.
