Since beta_88 (b52c71f) the P4 stored its BLE name and PIN only when BLE was on
at boot and the C6 came up for it. A unit that booted with BLE off (or once had
it off, since that is saved) then failed every enable at once, and the UI read
every refusal as "Not enough free memory for Bluetooth", Wi-Fi off or not.
- main.cpp stores the parameters on every boot; storing them does not touch the C6.
- enableBle() brings the C6's BLE controller up on a runtime cold start
(hostedInitBLE) before NimBLE, or NimBLE would start against no controller.
- The transport records why a cold start did not happen (no parameters, the
memory guard, the radio) and the toast says so; only the guard is about memory.
Not run on a P4 yet: the P4 build has both strings in it.
