### Reading Conversational Awareness State
After requesting notifications, the AirPods send a packet indicating the current state of Conversational Awareness (CA). This packet is only sent once after notifications are requested, not when the CA state is changed.
The packet format is:
```plaintext
04 00 04 00 09 00 28 [status] 00 00 00
```
- `[status]` is a single byte at offset 7 (zero-based), immediately after the header.
- `0x01` — Conversational Awareness is **enabled**
- `0x02` — Conversational Awareness is **disabled**
- Any other value — Unknown/undetermined state
**Example:**
```plaintext
04 00 04 00 09 00 28 01 00 00 00
```
Here, `01` at the 8th byte (offset 7) means CA is enabled.
