――A memo that tried the article of typing
from a USB keyboard that was garbled (emulated) on a BT keyboard and inserted into a Raspberry Pi using Bluetooth.
-** Original article **
- Emulating a Bluetooth Keyboard with a Raspberry Pi and Python (Raspbian Jessie/Bluez 5 version)
↑ seems to correspond to the recent environment by referring to ↓.

-Isn't it BLE? (I couldn't detect it from my smartphone)
