Arduino HM10 Bluetooth Test for Unity Plugin
|
|
Language: Wiring/Arduino
|
|
|
|
This program waits for input from the Unity app and reflects any strings back
|
|
to that app. If this app receives a single byte of 0x01 it will toggle the led
|
|
|
|
The circuit:
|
|
- connect HM10 BLE device to serial RX/TX lines
