- message_id = (30A & 0x0FF) = 10

data :
vcan0 30A [8] 07 D0 45 80 3C 00 00 00
means:
| Name | data | value |
|---|---|---|
| device_id | 3 | 3 |
| message_id | 0A | 10 |
| rpm | 0x07,0xD0 | 2000 |
| voltage | 0x45,0x80 | 5.5V |
| current | 0x3c,0x00 | 1A |
| vibration | 0x00,0x00 | vibration |
data :
vcan0 30B [4] 45 00 2F AE
| Name | data | value |
|---|---|---|
| device_id | 3 | 3 |
| message_id | 0B | 11 |
| waterTemperature | 0x45,0x00 | 5 celcius |
| humidity | 0x2F,0xAE | 0.12 |
