Bluetooth Card10 Service

Warning

The specification is still work in progress

The Card10 Service implemented a direct Hardware access of the card10.

BLE Service

The current draft uses following service specification:

Time update characteristic

The time update characteristic makes it possible to set 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.

Dataformat:

0

1

2

Rocket0

Rocket1

Rocket2

  • Enable only Rocket0: 0xff0000

  • Enable all rockets with 50% brightness: 0x7f7f7f

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.

Dataformat:

0

1

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

LEDs above characteristic

This characteristic set 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
