Q15 After Bluetooth is connected to an Android phone, how to switch the Bluetooth encoding? Why is Aptx-Adaptive preferred for Bluetooth connections?

Q15 is a receiving device. What kind of Bluetooth code it receives depends mainly on the mobile phone. Generally speaking, if you need to switch the Bluetooth code, you need to switch the Bluetooth transmission protocol in the mobile phone developer mode.

For the Bluetooth codes supported by Q15, there is a Bluetooth code support switch on FiiO Control. If you do not want Q15 to receive a certain Bluetooth code, you can turn off the corresponding Bluetooth code on FiiO Control.

If you need to switch to other Bluetooth encodings (such as LDAC), follow these steps:

1. Enter FiiO Control App-Q15-Status interface

2. Click ‘Bluetooth encoding selection’

3. After unchecking the ‘aptX-Adaptive’ option, click ‘OK’

4. Q15 will automatically restart and connect to the phone in LDAC or other Bluetooth encoding format

Note: Apple phones cannot switch Bluetooth encoding, the system automatically switches
