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.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?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!

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.

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?
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!
