如何在Python中使用BLE通知

Question

I am working with sensorTags and LightBlue Beans BLE devices, but can not find a way to interact with them using notifications. I have tried several codes in python which implements read/writes but I need to speedup the access to the sensors data. Any suggestion? I'm using a raspberry based platform and python.

Answer 1

You will have an easier time using Node.js, these are actively worked on.

For Central devices: https://github.com/sandeepmistry/noble

For Peripheral devices: https://github.com/sandeepmistry/bleno

Answer 2

This Gist shows how to use python-dbus to read out scratch characteristics data: https://gist.github.com/jsiverskog/0afa43225bdbe8e803cb

From my tests it seems to be quick to react on updates in the data (of course somewhat dependent on your actual implementation on the Bean). It should provide enough information to get you going.
