# The RFduino BLE currently can only be used as a peripheral device.
# The RFduino Service UUID is 2220.
# It uses three charactertics with UUIDs; 2221, 2222, 2223
# All sketches communicate via the DATA out buffer and DATA in buffer.
# The content type of the DATA buffer is not discoverable and each application
# requires the arduino sketch and the client APP to have pre-knowledge
# of the contents schema of the DATA buffers.
# UUID 2221 (handle 0x000e) represents the sending DATA buffer on the RFduino.
# UUID 2222 (handle 0x0011) represents the receiving DATA buffer on the RFduino.
# UUID 2223 (handle 0x0013) is a receiving buffer. It's use is yet unknown to me.
# The actual handle for the sending DATA buffer is 0x000e.
# The actual handle for the receiving DATA buffer is 0x0011.
# NOTE: RFduino needs the random flag for some reason.
# Something like...
# gatttool -b <BLE_MAC> -t random -I
In this experiment I want to send RGB values to the RFduino and I want them
to be persistant.
I modified RFduino's example sketch ColorWheel.ino. Their example turns
on the RGB LEDs upon connecting. And turns them off upon disconnecting.
Since I want to send a RGB value that I expect to not go away, I comment
out their code. Also upon connecting I don't want a sudden flash of all
the LEDs before changing to my new settings, so I comment out that code as well.
