se4u / bluetooth_kivy.py
Created January 12, 2020 00:44 — forked from cuibonobo/bluetooth_kivy.py
Bluetooth example with Kivy. A more fleshed-out example here: https://github.com/tito/android-demo. A more modern way of doing it: https://github.com/kivy/plyer. And this guy used Kivy to connect to an Arduino: https://github.com/brean/arduino-kivy-bluetooth. Native Kivy code (?): https://groups.google.com/d/msg/kivy-users/n_cMbFzf_1A/5edKgQgycx0J
# Same as before, with a kivy-based UI
'''
Bluetooth/Pyjnius example
=========================
This was used to send some bytes to an arduino via bluetooth.
The app must have BLUETOOTH and BLUETOOTH_ADMIN permissions (well, i didn't
tested without BLUETOOTH_ADMIN, maybe it works.)

Created December 22, 2019 22:39
Simulate effective sample size computation to check the example given in "Lessors from Contextual Bandit Learning in a Customer Support Bot" by Karampatziakis et al.

eps_greedy_action = rule if np.random.rand() > eps else np.random.choice(k)

Example of python meta programming by modifying the token sequence output by the inbuilt tokenizer and codecs used for python parsing.
## --- Save this file as pymeta.py ---- ##
# inspired by pyxl and github.com/SyrusAkbary/interpy
