bleak VS remi

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.

Have you considered a remote use case, using something like https://github.com/rawpython/remi ? My SD machine is a headless Linux box, so I'd love to be able to run this on the server where it's local to the images (and perhaps have a multi-image / gallery view)?

How does it compare with remi? https://github.com/rawpython/remi

Looking at the examples, for quick UIs, REMI seems simpler. And PySimpleGUI (https://github.com/PySimpleGUI/PySimpleGUI) offers REMI as a backend to deploy on web too (PySimpleGUI is pretty simple to learn).

Making GUIs is always a fair amount of work/overhead on whatever you are working on, and I like to stay in Python when possible (I've used REMI (https://github.com/rawpython/remi) to create web apps before in Python). Thanks for creating this. I look forward to updates!

This is cool. How does it compare to Remi? I haven’t used it but I am curious

remi works by pre-defining js and html elements

I'd like to point to the excellent REMI [1] library that provides similar capabilities to Lona. You can create web apps by only writing Python. They can also be executed as GUI programs. You can even choose REMI to be the output backend of PySimpleGUI [2].

Not sure what the differences are, but good to know there are similar approaches :) Maybe every project can learn from each other. Thanks for sharing!

I have installed the last version of REMI (from https://github.com/dddomodossola/remi). When I launch the examples, like hello_world, all is perfectly displayed but the obtained UI is not reactive: no effect when I click on buttons, etc. I tried with Python 2 and 3.

I never used mpld3, but you can see an example of matplotlib here remi/matplotlib_app.py at master · dddomodossola/remi (github.com) .

python3 -m pip install git+https://github.com/dddomodossola/remi.git
