[JackeyPSSPL]

Hi Team,

I verified the documentation and checked it but was not able to identify the below method I also checked the TTLock SDK version is "3.2.6" but not get the below method from this SDK.

I want to update the sound level of my Bluetooth device so how can I do this please help me.

Documentation link

46. Set sound volume
    public void setLockSoundWithSoundVolume(SoundVolume soundVolume, String lockData, SetLockSoundWithSoundVolumeCallback callback)

47. Get sound volume
    public void getLockSoundWithSoundVolume(String lockData, GetLockSoundWithSoundVolumeCallback callback)

Note: If possible please give an example so it would be easy to understand
