Aurora DS5

Default pad latency follows the TV

The 35 ms default of 1.7.40 relies on a fix that only matches the Bluetooth stack build of the LG G4 it was developed on. Aurora now checks this per TV:

• Stack recognised: default pad latency 35 ms, as before.
• Any other stack (other firmware builds, Realtek Bluetooth chips, no root): default 70 ms, nothing in the stack is touched.

A latency you set yourself is kept either way.

Fixes for TVs with a different stack

• 1.7.40 searched an unknown stack every 10 s while a pad was connected, on the thread that feeds the pad. That search takes 30–100 ms and could cause audio gaps. It now runs only while no pad is bound, and ever more rarely (10 s to 5 min).
• The stack's memory is opened read-only until a write is actually due, and is only written after the code at that address has been re-checked.

Fix on the G4

• If the daemon was stopped during a session (for example by an app update), the Magic Remote stayed slow to wake until the end of the next stream. The daemon now puts the original values back when it starts.

To switch the mechanism off: touch /tmp/ds5_leconn_off on the TV (the default then reads 70 ms).
