Just so you're aware: Bluetooth midi is a good substitute for USB midi connection. Both have low latency, USB slightly better.
But Bluetooth audio is often not a good substitute for USB audio, since Bluetooth audio has much higher latency.
For example, with USB audio you can feasibly play on your digital piano, route midi to computer running Pianoteq, and have Pianoteq sound routed back to digital piano speakers via USB audio. Latency will be low, will sound okay.
But you won't have a good experience doing the same thing with Bluetooth audio. Latency is higher, there will be noticeable gap in time between you pressing piano key and hearing the sound come back from Pianoteq. (Bluetooth audio is very useful for some things, e.g., playing an audio file background track on your computer and route it to your piano speakers; in this case the latency still high but makes no difference because you're not dealing with "real time" responsiveness to keypresses on an instrument.)
No reason to worry, P515 is excellent choice and has both USB audio and analog audio in, so you're covered whatever you want to do.
