Bluetooth Card10 Service¶
The specification is still work in progress
The Card10 Service implemented a direct Hardware access of the card10.
The current draft uses following service specification:

LEDs above characteristic:
42230220-2342-2342-2342-234223422342read and write no reponse
Light sensor characteristic:
422302f0-2342-2342-2342-234223422342read no response
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
Thu Aug 15 19:40:45 UTC 2019 :
0x0 0x0 0x1 0x6c 0x96 0xcb 0xf8 0xcc
The vibra characteristic makes it possible to let the card10 for given millisecound in a
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.
Enable only Rocket0:
Enable all rockets with 50% brightness:
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.
set led blue:
LEDs dim <Position> characteristic¶
The LEDs dim <Position> characteristic makes it possible to dim LEDs by position.
Just write a
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
This characteristic makes it possible to activate the flashlight.
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.
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:
Light sensor characteristic¶
The light sensor characteristic makes it possible to read the current value of the light sensor by receiving a
The range of this sensor is between 0 (
0x0) and 400 (
