Unable to change HVAC temperature using adb inject-vhal-event command

[Sagnik Dhar]

Hello, 

I am trying to test the Android Automotive HVAC using adb commands. I am able to change fan speed  to 3 using this command, 

adb shell dumpsys activity service com.android.car inject-vhal-event 0x15400500 1 3

0x15400500 is the Vehicle Property ID for the property HVAC_FAN_SPEED as mentioned here, https://developer.android.com/reference/android/car/VehiclePropertyIds#HVAC_FAN_SPEED

However, I am not able to change the temperature using the same command. More specifically, I am using this command to set temp to 65F.

adb shell dumpsys activity service com.android.car inject-vhal-event 0x15600503 1 65

Is there any other parameter that I need to pass?

Regards

Sagnik

Hi, if that doesn't work you can try the "Kitchen Sink" app inside of Android Automotive to try to figure it out.
