KW41Z BLE deep sleep

I'm experimenting with the Heart Rate Sensor sample project (KDS, bare metal OS) on the USB-KW41Z board.

When I enable the low power feature however, I don't get the expected advertising. (And the SWD connection dies, which is expected) The only real code changes are setting these flags in the preinclude file:

#define cPWR_BLE_LL_Enable 1
#define cPWR_UsePowerDownMode 1
#define gTMR_EnableLowPowerTimers 1
#define cPWR_CheckLowPowerTimers 1

If I modify the project to start advertising immediately, I get advertisements for a second or two then nothing.

Is the BLE deep sleep feature known to work with this sample? Is there more configuration required? Any suggestions or advice appreciated.

NOTE: I've gotten past this particular symptom, but still seeing other issues with advertising while BLE_LL deep sleep is enabled. Will be updating later.
