Dear Apple:
Our operation steps are as follows:
1、 pair the Apple phone with the Garmin watch via Bluetooth.
2、When another app is in the foreground, use BLE Bluetooth to send a custom broadcast. However, since the data is quite large and cannot fit entirely in the broadcast, the remaining data is sent in the BLE Scan Response. The other device starts BLE scanning.
3、our BLE packet capture shows that the Apple phone does not send the BLE Scan Response.
Currently, we have found that only the iPhone XS Max has this issue; it is still unknown whether other iPhone models have the same problem.
