Our product is based on an STM32WB5MM. On the STM32WB, we have privacy enabled and use the filter/acceptance list.When the filter/acceptance list is not enabled, we want the device to be able to connect to a Garmin device. Unfortunately, the device does not appear in the scan results. We’ve confirmed that when privacy is disabled, the device appears in the results without issues. This Garmin incompatibility with BLE devices using resolvable private address (RPA) is known (https://forums.garmin.com/developer/connect-iq/i/bug-reports/not-all-ble-devices-found-by-scanning?CommentId=0740ab84-c44f-49a2-a165-5aff687d5435).My question is: is it possible to keep privacy enabled while advertising with a static random address instead of an RPA?If this is not possible, what workaround could we use to allow both RPA-compatible and non-RPA-compatible devices to connect?Thanks in advance.

Hello community,I need to use the AES-CMAC functionality of the STM32L562QE.The datasheet says that it is supported :But it seems that the reference manual doesn't say anything about CMAC functionality.Is there really a way to use the AES coprocessor to compute AES-CMAC, or did I miss something ?Thank you in advance,Adrian

Hi ,I can find AES DPA in TFM demo application, but  can't find TDES DPA implementation in TFM.Please advise how to implement TDES DPA. 

Hello,I created already several SD-cards images (.raw) using the `create_sdcard_from_flashlayout.sh` script, from both starter kit and Yocto build.Note: Currently working on the STM32MP256 evaluation board.We would like to have something similar with USB:1) Create a *.raw image2) Use `dd` or Raspberry Pi Imager to flash the USB memory3) Select the boot pins on the evaluation board (all-zeros for USB boot)4) Insert the USB memory5) Power-on and wait until Linux is loaded.To my surprise, this process that works fine for sdcards does not work for USB (The card does not boot). This also makes sense considering that :* The script is called `create_sdcard....` and not `create_usb`* The *.tsv are either _emmc_ or _sdcard_But why there is not _usb_ tsv or create_usb script?All the documentation found about USB is by connecting the computer and using the USB link to flash the emmc. This is fine in some environments, but not in others.How to create a bootable OpenST-Linux USB memory ?

I am currently working with the STM32H573I-DK discovery kit and am trying to enable Ethernet connectivity using LWIP in STM32CubeMX and STM32CubeIDE. However, I have noticed that the LWIP option is not available in STM32CubeMX for this board.Could you kindly guide me on how to enable Ethernet functionality with LWIP on the STM32H573I-DK? Is there any recommended procedure or workaround to add Ethernet support if the option is not directly available in STM32CubeMX?Any guidance, reference materials, or example projects would be highly appreciated.How to use the LwIP Ethernet middleware on the STM32H5 series....I already saw this...but so many error

I have a HC-06 module being run via USART from a STM32F411RE NUCLEO board.When I run STBLEToolbox (or LightBlue) the module doesn't appear in the scan list (all filters are off)Yet when I open my Bluetooth settings on my phone the module shows up & I can pair with it. The module still doesnt show in the app even when paired though but I can use a serial Bluetooth app to connect to it. What am I missing here?

I googled how to make this change.  I found several references to class members setBackgroundColor, setButtonColor, setBoxColor but none of them work (are members).  I checked BoxWithBorderButtonStyle.hpp and could find no reference to any of these nor any (obvious) function that would allow me to change the color.  The documentation that I can find online does not match my results.  Any feedback would be helpful.  I am using TouchGFX 4.24.2

Hello everyone,I'm trying to use the loopback mode on the  STM32F4DISCOVERY. I configured the CAN peripheral and i started the transmission by adding data but when i try to verify the reception process i can't find data in the RxHeader.

Meanwhile STM goes with Microsoft AZURE RTOS - ok, fine, feature rich, obvious! But "I miss a feature": open and read a file from the MCU internal flash memory (as a const file content, as array of characters, without a need for a sector based, FAT based, a file system). In the past, on STM MCUs and FW (CubeMX drivers and demos) - it was possible to have web pages for a HTTPD daemon (web server) located in MCU Flash memory and read the file data bytes and send it as browser response. Now, with AZURE RTOS - all seems to be stored on a FAT (sector based) file system. Why so complicated?! Details: I have ported the STM32U575-EV USB_ECM project to a NUCLEO-U575ZI-Q board. It needs the external SD Card! So, I had to put the web page files on external SD Card (with external SD Card adapter for a NUCELO board). I want to get rid of this SD Card and have my web pages sitting in the MCU Flash memory. OK, I understand, AZURE FileX is very flexible, it can also support SDRAM as file system MEDIA,

I want to trigger a RFID reading at certain intervals using ST25R3911 and from this I want a RFID reading to be done within 1 second. When I try this in RFAL (using democode for polling): err = rfalNfcDiscover( &discParam ); if( err != RFAL_ERR_NONE ) { printf("Err %d!\n\r", (int)err); return false; } state = DEMO_ST_START_DISCOVERY;   It takes about 10 second to do a RFID reading which is way too long. When analyzing what RFAL is doing this is what I see when checking gNfcDev.state in rfalNfcWorker: void rfalNfcWorker( void ) { ReturnCode err; rfalWorker(); /* Execute RFAL process */ printf("State %d\n\r", (int)gNfcDev.state); switch( gNfcDev.state ) {   RFAL_NFC_STATE_POLL_TECHDETECT - about 5 secondsRFAL_NFC_STATE_POLL_COLAVOIDANCE - about 4 seconds Which is obvisously too long for a user to hold an RFID card in front of the reader. What is RFAL doing and how can I reduce time from request reading to reading done within

I have PCB which support 3.3 V or 4 V power supply which I want to connect with ST25R3911B. I want to run 4V power supply as it can provide more current and I assume outputpower of ST25R3911B  will be higher on 4 V than on 3.3 V.In data sheet of ST25R3911B  it is stated that power supply is 2.4 to 5.5V so this should be fine. BUT when checking the registers 4.0V seems to be an invalid voltage: IO configuration register 2Bit 7 - sup3 V0: 5 V supply1: 3.3 V supply 5 V supply, range: 4.1 V to 5.5 V3.3 V supply, range: 2.4 V to 3.6 Vmin. 3.0 V for VHBR So the question is what will happen when using 4.0V for 5V supply range? Will it not work at all?Also when running PCB on battery voltage this will give voltage bewteen 4.0 to 3.0 V, which seems to be outside specification of ST25R3911B.Can someone help how to use use ST25R3911B in my application? 

Hey there!I'm trying to design a TouchGFX GUI using a background image that has some placeholder 'boxes' (that will eventually hold status of things) and custom flex buttons. I'd like these buttons to have rounded edges, so I am using PNGs with transparency around the edges. However, TouchGFX seems to ignore the alpha of 0 and fill that space with blue - see screenshots of the buttons below:They appear the same way in the simulator. Am I doing something wrong? Thanks for your help! Julia

Is it possible to create a custom widget in TouchGFX using code, specifically in STM32CubeIDE? I would like to start with a blank screen, add a custom widget, import the generated project into STM32CubeIDE, and then write code for the custom widget. What are the steps involved in achieving this?

Hi everyone,I'm at the start to build up my transceiver based on the STM32WL33 with the Nucleo-board NUCLEO-WL33CC1 and the Mainboard MB1801. I want to use the IOC in the Cube IDE.If you are trying to send the raw HF Data to a GPIO Pin:  Change  __HAL_MRSUBG_SET_RX_MODE(RX_NORMAL); to __HAL_MRSUBG_SET_RX_MODE(RX_DIRECT_GPIO); add /*Configure GPIO pin : PB1 */ GPIO_InitStruct.Pin = GPIO_PIN_1; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_PULLUP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; GPIO_InitStruct.Alternate = GPIO_AF4_SUBG; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct); and measure at PB1 (it took me some time to get this solution, maybe it helps someone out there)Further information https://www.st.com/resource/en/reference_manual/rm0511-stm32wl33xx-armbased-wireless-mcus-with-subghz-radio-solution-stmicroelectronics.pdfhttps://www.st.com/resource/en/user_manual/um3438-description-of-stm32wl3-hal-and-lowlayer-

Hello,I am using an STM32F401 board and trying to read a sensor using DMA. The sensor is a receive only sensor, i have tested with block SPI if the sensor works and it does. I am trying to read the sensor via DMA as it must be implemented with multiple SPI sensors, yet i can't get the buffer to read correctly? something like that. Launching the code with DMA in receive only causes the DMA interrupt, that would signal a succesfull read, to trigger before the data transfer is complete. I can see an SCLK from the MCU to the Sensor and some data that returns. Just not correct data. I have also tried using SPI Half Duplex Master, as this allows for prescaling the CLK output as well. Connecting the Sensor to the MOSI pin instead of the MISO and using the DMA TransmitReceive, while using dummy packages for the transmit. This causes the code to crash after a few succesfull DMA completions, yet the data is still incorrect even in the completed DMA requests. I have

Hello everyone,I’m working on an STM32H747IIT6 based project that uses both Cortex-M7 and Cortex-M4 cores. Under Pinout & Configuration > System Core > Cortex_M7 (and similarly Cortex_M4) in STM32CubeIDE, there are several options such as:CPU I-Cache / CPU D-CacheMPU (Memory Protection Unit)TCM (ITCM / DTCM) EnableBackground Region Privileged AccessMPU Instruction AccessCache and MPU Region SettingsI’d like to understand the best practices for configuring these settings, especially when running multiple middleware components like FreeRTOS, LwIP (Ethernet), USB, I2C, and an SD card interface. Here are some questions I have:Cache Enable/Disable: Under which circumstances should I enable both Instruction Cache and Data Cache? What are the typical pitfalls (e.g., DMA conflicts) when D-Cache is enabled?MPU Configuration: If I plan to use the MPU, how do I decide which memory regions need different cache policies or access permissions? Are there any recommended templates or applica

In my design VDD = 2.9V and VDD_IO = 2.0V.  To minimize current when the NFC feature is not needed, I want to power down the VDD supply.  But I want to leave VDD_IO powered on.  Is there a concern with VDD being powered up and down repeatedly while VDD_IO is always on?

Hello!I've been tasked to use the STEVAL-PROTEUS1 board with the ISM330DHCX to detect anomalous motor behavior. I've confirmed the board works fine when using other firmware and works as a WCID & MSC with datapro. However, when I try to flash the auto generated datalogger firmware from Nanoedge AI for serial data collection (via FUOTA), it does not create a COM port I can point the serial monitor at. I'd be grateful if someone could advise me of mistakes I might've made along the way, or if flashing via FUOTA does not work because there is a second flash bank or something similar. While I do currently have access to a STLINK V3-MINIE, I would prefer if flashing via FUOTA was an option, as it makes for an easier showcase.Thanks in advanceHaze
