STM32WBA BLE Direction Finding with Low Power

[JPortilha]

Hello,

I am currently working with the STM32WBA65RI for BLE Direction Finding using connectionless mode. I would like to know if it is possible to use a low-power mode such as Standby with RTC, allowing the board to consume only a few nanoamps, then wake up periodically via the RTC, perform advertising for a defined period, and return to Standby mode.

Could anyone provide guidance or share experience with this approach?

Best regards.

Also, why does the CubeMx forces the use of Sequencer when I add the STM32_WPAN to handle the bluetooth stack?

Hello @JPortilha ,

This wiki page demonstrates how to generate a BLE server application using STM32CubeMX with RTC configuration: STM32WBA Bluetooth® Low Energy - STM32CubeMX Application Conception 

You can also start with basic projects such as the BLE_HeartRate, which uses low power. 

The Timer server utility for your application. Part 4.5 Timer server of the AN5289 may help you.

It seems the use of the sequencer is to manage all the tasks of the project.

I advise you to have a look at the Known limitations when selecting the STM32WBA series using STM32CubeMX.
