HVAC_SIDE_MIRROR_HEAT
What it is
Side Mirror Heat
Increasing values denote higher heating levels for side mirrors.
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The maxInt32Value in the config data represents the maximum heating level. The minInt32Value in the config data MUST be zero and indicates no heating.
This property is not in any particular unit but in a specified range of relative heating settings.
This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.
How the ID is built
A property ID is a 32-bit value packing four fields. Reading 0x1440050c apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x04000000 | MIRROR |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x0000050c | 0x50c |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.HVAC_SIDE_MIRROR_HEAT, areaId);This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
