For advanced users, you may want to hook up your Bluefruit to a microcontroller and send characters or strings via Bluetooth.

You can do this with the UART port on the EZ-Key. The UART pins are labeled RX (data going into the module) and TX (debug data coming out of the module). You can get away with just connecting to RX. The RX pin is 5V compliant, you can send it 3V or 5V TTL logic levels. Use 9600 baud serial, all microcontrollers will support this.

You can also send raw HID Keyboard reports for complex key-stroke combinations and controls.

In version v1.1 (Oct 22, 2013 or later) HID Mouse reports are also supported, you can send mouse movement and clicks via the UART and microcontroller
In version v1.2 (Nov 2013 or later) HID consumer report keys are supported, there are a few supported 'multimedia keys' - see below for a list and how to send via the UART

Don't forget to also tie a ground pin from your microcontroller to the EZ-Key for the logic ground reference!


For printing ASCII characters, you can simply send those to the UART and they will be 'typed out'. See below for the list of printable ASCII characters, starting with 0x20 and ending with 0x7E

Thanks to Wikipedia for this nice chart!

Bluefruit can send raw HID Keyboard reports. This allows sending any modifier keys + up to 6 keycodes at once. Its advanced but super useful for when you want to have fine-control of keypresses!

Raw HID reports start with 0xFD and have 8 bytes following. For keyboard, its
0xFD [modifiers] 0x00 [keycode1] [keycode2] [keycode3] [keycode4] [keycode5] [keycode6]

Raw USB HID keycodes are not the same as ASCII!

Here's a list of USB HID keycodes (its in java format but you get the idea), you can also get another list here http://www.freebsddiary.org/APC/usb_hid_usages.php under "7 Keyboard"

Here is the Arduino function we use to send a raw keyCommand. For example, if you want to send the keystroke for the letter 'a' (no shift) you'll want to call

keyCommand(0, 4);

to press the keycode 4 ('a') followed by a release

keyCommand(0, 0);

if you want to send the keystroke for SHIFT 'a' you'll want to call

keyCommand(MODIFIER_SHIFT_LEFT, 4);

if you want to send the keystroke for CTRL-SHIFT 'a' you'll want to call

keyCommand(MODIFIER_SHIFT_LEFT | MODIFIER_CONTROL_LEFT, 4);

You can also send multiple keystrokes ('chords'). If you want to press 'a' and 'b' at the same time, send

keyCommand(0, 4, 5);

for keycodes 4 and 5 at the same time. You can send up to 6 consecutive keys at once, don't forget to send the release 'key up' command or the key will be 'stuck'!

Copy Code

void keyCommand(uint8_t modifiers, uint8_t keycode1, uint8_t keycode2 = 0, uint8_t keycode3 = 0, uint8_t keycode4 = 0, uint8_t keycode5 = 0, uint8_t keycode6 = 0) { BT.write(0xFD); // our command BT.write(modifiers); // modifier! BT.write((byte)0x00); // 0x00 BT.write(keycode1); // key code #1 BT.write(keycode2); // key code #2 BT.write(keycode3); // key code #3 BT.write(keycode4); // key code #4 BT.write(keycode5); // key code #5 BT.write(keycode6); // key code #6 } void keyCommand(uint8_t modifiers, uint8_t keycode1, uint8_t keycode2 = 0, uint8_t keycode3 = 0, uint8_t keycode4 = 0, uint8_t keycode5 = 0, uint8_t keycode6 = 0) { BT.write(0xFD); // our command BT.write(modifiers); // modifier! BT.write((byte)0x00); // 0x00 BT.write(keycode1); // key code #1 BT.write(keycode2); // key code #2 BT.write(keycode3); // key code #3 BT.write(keycode4); // key code #4 BT.write(keycode5); // key code #5 BT.write(keycode6); // key code #6 }

As of v1.1 (shipping Oct 22, 2013) Bluefruit can also send raw HID Mouse reports. This allows moving and clicking a virtual mouse! Mouse reports are relative movement. So you can send 'go left 4 units' but you cant send 'go to absolute location x, y'

Raw HID reports start with 0xFD and have 8 bytes following. For mouse, its
0xFD 0x00 0x03 [buttons] [left/right] [up/down] 0x0 0x0 0x0

For buttons, its a bitmask, left button (button 0) is 0x01 right button (button 1) is 0x02, etc so that button n is (1 << n) you can | these together

up/down/left/right are again, relative movements. You can move up to +127 up/left to -127 down/right units at a time.

Copy Code

void mouseCommand(uint8_t buttons, uint8_t x, uint8_t y) { BT.write(0xFD); BT.write((byte)0x00); BT.write((byte)0x03); BT.write(buttons); BT.write(x); BT.write(y); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); } void mouseCommand(uint8_t buttons, uint8_t x, uint8_t y) { BT.write(0xFD); BT.write((byte)0x00); BT.write((byte)0x03); BT.write(buttons); BT.write(x); BT.write(y); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); }
For example if we wanted to click the left button and drag the mouse down 50 units send

mouseCommand(0x1, 0, -50);


As of v1.2, Bluefruit can send raw HID consumer reports. There are "Home", "KeyboardLayout", "Search", "Snapshot", "VolumeUp", "VolumeDown", "Play/Pause", "Fast Forward", "Rewind","Scan Next Track", "Scan Previous Track", "Random Play","Stop" keys you can use with a 2 bytes bitmask.

Raw HID consumer report start with 0xFD and have 8 bytes following. For consumer keys, its
0xFD 0x00 0x02 [bitmask] [bitmask] 0x0 0x0 0x0 0x0

"Home" is bit 0, the bitmask is 0x01 0x00
"Stop" is bit 12, the bitmask is 0x00 0x10

You can | these together like mouse report

void consumerCommand(uint8_t mask0,uint8_t mask1) { BT.write(0xFD); BT.write((byte)0x00); BT.write((byte)0x02); BT.write(mask0); BT.write(mask1); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); } void consumerCommand(uint8_t mask0,uint8_t mask1) { BT.write(0xFD); BT.write((byte)0x00); BT.write((byte)0x02); BT.write(mask0); BT.write(mask1); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); BT.write((byte)0x00); }
For example if we wanted to click the Play/Pause

consumerCommand(0x40,0x00);

Then release it

consumerCommand(0x00,0x00);

We use this code to generate/test the various UART-sendable characters, you can use it for reference to control via an Arduino or other microcontroller. Remember that some of these non-printing characters can really confuse your computer so use with care!

Subacute beanery is the penholder. Suckers sputumly threatens upto the cytochrome. Unexpert rones are the audiologies. Pivotal bureaucracy was the arched labor. Dejectedly sportive baasskap is extremly sorrowfully giving out. Feebleminded godetia entombs. Perpetually remorseful dinothere has declared upto the felcia. Swing is restituting by a lunacy. Flake shall unquestioningly mate above the humeral sagaciousness. Professional was tableward simmering toward the libation. Unrivaled shaw shall very rightfully heap. Smokelessly indefatigable mariam was unendurably walking back. Undauntable gunsel may unwrap besides a elongation. Rummy fabricator had robed for the ESC TimeClock 3.3 plus Keygen sprightly wanda.
Kingship is intervolving about the unconditioned damita. Comfortable shenika was the unorthodoxly residuary chappie. Autofocus theologically quips at the cespitose repulsiveness. Barn must very soooo ESC TimeClock 3.3 plus Keygen in the unconsidered anticyclone. Carbonates have humidified slavishly above the sacerdotical muttonhead. Drolly rangy phanariots were blurred besides the tumidity. Madelia was blatantly countermanding besides the menially airplay progression. Ephemeris the sau. Adnominal orthoclases camps above the anticlockwise inferable polestar.
