## How to use this example

### Configure the project

```
idf.py menuconfig
```

### Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output.

```
idf.py -p PORT flash monitor
```

(To exit the serial monitor, type ``Ctrl-]``.)

## Example Output

The output when receiving metadata:

```
I (81700) RC_CT: AVRC event notification: 2
I (81740) RC_CT: AVRC metadata rsp: attribute id 0x1, 
I (81740) RC_CT: AVRC metadata rsp: attribute id 0x2, 
I (81740) RC_CT: AVRC metadata rsp: attribute id 0x4, 
I (81750) RC_CT: AVRC metadata rsp: attribute id 0x20,
```
