Myo Armband Bluetooth Interface for macOS

FreeMyo.py

BLE Bleak-based Async Python interface to the Myo Armband that doesn't require a dongle or the MyoConnect software. This has been primarily designed for macOS and its UUID-based BLE connections.

Based on specs from Thalmic Labs: https://github.com/thalmiclabs/myo-bluetooth and work done by PerlinWarp on pyomyo here: https://github.com/PerlinWarp/pyomyo and also Open-Myo: https://github.com/Alvipe/Open-Myo

This is a work in progress.

Requirements

• Python 3.10 (due to the use of the match expression)
• Bleak
• DearPyGui

---

Instructions

1. Open myo_config.yaml and change the device_uuid value to the value of your Myo's UUID
2. Run the following: python3 myo_gui.py

---

Troubleshooting

• If you're not sure about the Device UUID, download an app like BlueSee or Lightblue and do a scan. It'll come up under the name Myo and you can just copy the Device ID from there.
• If you're sure you have the correct UUID and the Myo still isn't connecting, try draining the battery. I don't know if it keeps any information about previous pairings, but it will drop that info when the battery is drained enough. Personally I noticed when the battery got down to 2 or 3%, I was able to connect and didn't have any issues after that.

Future Upgrades

• Write EMG data to a local database
• Select between multiple Myo's
• IMU data
