Here are my findings of the reverse engineered Maia Ds2 bluetooth protocol
The Maia Ds2 is an excellent audio amplifier. Unfortunately it is not easily controllable without using the proprietary app by pro-ject. This repository contains all nesessary information for one to send the reverse-engineered commands to the amplifier via a raspberry pi or some other bluetooth-capable device.
The commands just have to be sent through a bluetooth serial console. As a test, you can use an app such as Serial Bluetooth Adapter to send test commands to your device. For this to work, you have to be connected to your device.
You need a device running python3 that is able to connect to a bluetooth device. I used a Raspberry Pi but theoretically it should work on any device.
Raspberry Pi:
-
Prerequisites:
- Raspberry Pi that is bluetooth-capable (RPI 3 or above)
- bluetooth ("pip3 install bluetooth" in command line)
-
Open a bluetooth connection to the Amplifier from your Raspberry:
- Either using the GUI or using rfcomm
- A more detailed explanation for rfcomm can be found here.
-
Edit and run the example and check if it is working.
- Fill in the mac address of your device, then run the example.
- The example basically just sends one of the commands to your amplifier. If your amplifier switches to channel 1 when running the example, then it does what it should do.

Commands
