Response
2 bytes:
{(Bit 6: NA)
(Bit 5: Red LED 1 – left one)
(Bit 4: Green LED 1 – left one)
(Bit 2: NA)
(Bit 1: Red LED 0 – right one)
(Bit 0: Green LED 0 – right one)}
{(Bit 0: Buzzer)}
Code ID
0x82-0x83
Description
Get MMI Mode (User interface)
Payload
None
Response
1 byte:
{(Bit 1: Buzzer Enabled) (Bit 0: LEDs enabled)}
Code ID
0x84-0x85
Description
Set MMI Mode (User interface)
Payload
1 byte:
{(Bit 1: Buzzer Enabled) (Bit 0: LEDs enabled)
(Bit 7 = 0:Buzzer config select, =1: Buzzer config
deselect)(Bit 6 = 0:leds config select, =1: leds config
deselect)}
Response
1 byte:
{(Bit 0: Success)}
Code ID
0x86-0x87
Description
Get MMI Signal (User interface)
Payload
1 byte:
{Signal number, 0 - 3}
Response
(1 + 3n) bytes:
{Number of steps, 0 - 4}
For each step:
{(Bit 6: NA) (Bit 5: Red LED 1) (Bit 4: Green LED 1) (Bit
2: NA) (Bit 1: Red LED 0) (Bit 0: Green LED 0)}
{Buzzer frequency, 0 – 0xFF * 50Hz = 0 – 12750Hz}
{Delay until next step, in tenth of seconds}
Nota : LED 0 = right one
LED 1 = left one
