STM32WB - Problems with BLE and RTC

Hey Guys, Im new to ST and have the following Problem with the STM32WB55.

I want to use the BLE function while the RTC is running in the background. The BLE should run for 10 seconds and shutdown after for 1 minute.

  1. When I go into the Standby Mode (Without BLE), i have a power consumption arround 800 nA, which is fine. When i'm doing this after I initialized the BLE with the "APPE_Init();", my power consumption is arround 0.6 mA, which is far to much. How can i fix this?
  2. Can i use the BLE without effecting the RTC? I saw that the BLE is using the RTC clock and also changes the prescaler.

Thanks a lot!
