Time update characteristic

The time update characteristic makes it possible to set and get the current time given in milliseconds after 1.1.1970 in the UTC timezone. The value is represented as a big endian uint64

  • Thu Aug 15 19:40:45 UTC 2019 : 0x0 0x0 0x1 0x6c 0x96 0xcb 0xf8 0xcc

Vibra characteristic

The vibra characteristic makes it possible to let the card10 for given millisecound in a uint16 vibrate.

  • One secound: 0xe803

Rockets characteristic

The Rockets characteristic makes it possible to address every three rockets. Just write there three byte array, one for evey rocket. On read you get the current value of all three rockets. Range is between 0 and 31 (0x1f) if send higher value it will set to max of 31.

Dataformat:

0

Rocket0

Rocket1

Rocket2

  • Enable only Rocket0: 0x1f0000

  • Enable all rockets with 50% brightness: 0x0f0f0f

Background LED <Position> characteristic

The Background LEDs <Position> characteristic makes it possible to address the bottom LEDs by position. Just write there three uint8 for the rgb color or read the current value.

Dataformat:

0

2

red

green

blue

  • set led blue: 0x0000ff

  • disabled: 0x000000

LEDs dim <Position> characteristic

The LEDs dim <Position> characteristic makes it possible to dim LEDs by position. Just write a uint8 between 1 and 8.

LEDs powersafe characteristic

This characteristic makes it possible to set the LEDs in powersafe mode. Even when set to zero, the RGB LEDs still individually consume ~1mA. Powersave intelligently switches the supply power in groups. This introduces delays in the magnitude of ~10µs, so it can be disabled for high speed applications such as POV

  • enabled: 0x01

  • disabled: 0x00

Flashlight characteristic

This characteristic makes it possible to activate the flashlight.

  • enabled: 0x01

  • disabled: 0x00

Personal state characteristic

This characteristic makes it possible to read and write the personal state. It writes always as persistant and it gives feedback if the value is in range and your firmware support it.

  • No State 0x0000

  • No Contact 0x0100

  • Chaos 0x0200

LEDs above characteristic

This characteristic set or read the current value of every 11 leds on the top module at once. By defining 11x rgb from left to right. You need also to set exchange a bigger MTU to use this feature.

  • set a rainbow beginnig with red on the right edge: 0xff0000ff8b00e8ff005dff0000ff2e00ffb900b9ff002eff5d00ffe800ffff008b

Light sensor characteristic

The light sensor characteristic makes it possible to read the current value of the light sensor by receiving a uint16. The range of this sensor is between 0 (0x0) and 400 (0x9001).

  • reading of 0x0e00 means 14
