#### Gemini 330 AE/AWB Debugging
On Gemini 330 series devices with firmware `1.8.21` or later, the following services are advertised when the corresponding SDK properties are supported:
* `/camera/get_color_ae_awb_status`
Returns the device AE/AWB status value.
```bash
ros2 service call /camera/get_color_ae_awb_status orbbec_camera_msgs/srv/GetInt32 '{}'
```
* `/camera/get_color_awb_gain`
Returns the raw Q8.8 `r_gain`, `b_gain`, and `g_gain` values.
```bash
ros2 service call /camera/get_color_awb_gain orbbec_camera_msgs/srv/GetAwbGain '{}'
```
* `/camera/set_color_awb_gain`
Sets raw Q8.8 RGB channel gains. Color auto white balance must be disabled before setting the gains.
```bash

```
