PWREN pin on RN52 should be always getting 3.3V as it's always asserted high from STM32 (i.e. it never changes state). Having said this, RN52 is configured to go to sleep after a period of inactivity (no active connections for 10 minutes). It then takes a CAN message coming from IHU to wake up RN52 and make it reconnect to the last known device on PDL.

RN52 gets configured on every reset of BlueSaab. There's an initialization routine that takes care of all necessary RN52 settings, so no manual configuration needed. This also the case for "legacy" systems starting with versions 5.x.
