bleak VS micropython-lib

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.

This is the current version of my code (excuse the mess it's become..), adapted from https://github.com/micropython/micropython-lib/blob/7128d423c2e7c0309ac17a1e6ba873b909b24fcc/micropython/bluetooth/aioble/examples/temp_client.py

STM32WB55 running MicroPython sounds like it'd suit. Should be fine for the power budget and aioble gives you one of the best BLE libraries on any platform. Documentation is generally good, though BLE is a little light (with some good examples and an active Discord channel!).

Pico (non-W) doesn't have upip (or mip, as that replaces upip now) or urequests because it doesn't have internet access required by them. In theory, you can download urequests from: https://github.com/micropython/micropython-lib/blob/master/python-ecosys/urequests/urequests.py or build your own MP image with it enabled. I don't know if it'll work as you want it to but it's worth a try.

Using SD-card on ESP8266 was more challenging. upip.install('sdcard') does not work.

But ChatGPT truly helped and suggested I find it in Github.

I don't think there's a mip list command or something like that. So your best bet is to look at the subdirectories in https://github.com/micropython/micropython-lib for a list of installable packages.

Do give it another try if you get a chance; I'd be genuinely interested in hearing about your experience. Be sure to check out the awesome list and micropython-lib if you're looking to fill gaps. There are still many holes but they're rapidly being filled in.
