FortiusANT VS bleak

My first rig was a rather second hand Tacx Flow with the old Fortius head unit - this is Pre-Zwift technology that connects to PC by USB cable. The PC uses Two cheap USB Ant+ sticks and a piece of software called FortiusANT which has been written to interface the older generation Tacx trainer with Zwift, Rouvey, trainerroad etc. it works really well and have a pretty good performance. For some reason I almost prefer it to my new Wahoo kickr

I've used Bleak in Python https://github.com/hbldh/bleak to connect to BLE devices from my laptop using the built-in card. I can iterate over services/characteristics, transmit stuff, use indicates, etc.

On the Raspberry Pi I recommend the Python library Bleak. It has some examples, such as the sensortag.py example that shows how to read characteristics, and the enable_notifications.py example that shows how to subscribe to notifications to read data from a characteristic.

We’ve automated testing on our BLE device. Our rig is based on a Raspberry pi configured with a Gitlab-runner that runs a test suite written in Python. We use a library called Bleak: https://github.com/hbldh/bleak

There are quite a few good BLE helper libraries out there that can make my job easier. But not all are created equal, some may be perfect for building peripheral BLE applications but may not be the best for central BLE applications. As I am going to make the Raspberry Pi the client, Bleak is a great one to use. Bleak is a GATT client software, capable of connecting to BLE devices acting as GATT servers. It is designed to provide a asynchronous, cross-platform Python API to connect and communicate with other BLE devices e.g. sensors.

There is a workaround in here although they claim this is fixed in most recent update: https://github.com/hbldh/bleak/issues/720

If your Python script on your computer should work as the GATT client and your code on the ESP32 as the GATT server, Bleak is an easy-to-use Python library. Have a look at the code examples.
