Low power modes in STM32WB mode and how to wake up the mcu

Hello, I am working on an application and the power consumption is a bit high as of now. I would like to know the different low power modes and how to wake up from those modes. Could you please help me with the documentation and sample codes?

STM32WB55: Power supply ripple/pulsation causing BLE TX to fail

We've switched to new DC-DC(LM3281) for main power supply and found that BLE TX stopped working correctly and not passing packet test anymore.After deeper investigation we found that our DC-DC in ECO mode has ripple/pulsation of 60mV/50uS, which caus...

Is there any example of using audio codec over I2S on STM32WB? I have the stm32wb5mm_dk BV_FULLBAND example and the audio SAI1 is initialized for external microphone mems. But i want to record 48kHz stereo audio instead and i am looking for an example.

Hi, i want to use the STM32WB5MM module to send audio data to my smart phone. I donwloaded the BVLPeripheral_FULLBAND example project and it receives 48kHz stereo audio from the phone and send it via usb to pc. Is it possible to send 48kHz to phone?

seems access to the backup domain is not granted when calling RTC_EnterInitMode() and RTC is clocked by LSI, at least on STM32WB55

Recently i experimented with the RTC modules and came accross an issue where HAL_RTC_Init() fails because RTC_EnterInitMode() fail with HAL_TIMEOUTAfter debugging, it seems that HAL_PWR_EnableBkUpAccess() need to be called before HAL_RTC_Init()It app...

STEVAL-STRKT01/FP-ATR-LORA1 can't find valid channel?

I am using STEVAL-STRKT01 with FP-ATR-LORA1. I have successfully joined the LoRa network (US915), but whenever the device tries to send data on the network it returns "Send Error" over the serial. By debugging the code, I have tracked the cause to be...

Any help would be appreciated. I am having an issue with the CubeMX software, namely it is taking too much data memory on my STM32WLJ1 board. I am trying to use the built in fatfs middelware in CubeMX. Is there a way to reduce its size/alternative?

The program size of my project is as follows "Program Size: Code=30996 RO-data=1548 RW-data=36 ZI-data=34980". The board i am using is a STM32WLJ1 board "256-Kbyte Flash memory and 64-Kbyte SRAM". I believe flash memory is causing me issues in my pro...
