Only want to pair with OOB data in SC mode (nothing else)Have already called  aci_gap_set_oob_data(0, 0, 0, 0, 0, 0) to gen OOB dataHave got said data from aci_gap_get_oob_dataParing packets show the OOB data bit is not set.aci_gap_set_authentication_requirement(0x01 - bonding enabled0x01 MITM enabled0x02 SC mode only0x00 key press notification not supported0x100x100x01 not using fixed pin0x00 public address)To see the packet on windows the device currently lies that it has a yes/no display but that should not affect the OOB data bit being set to present.

Hi, Can we use ISM303 for a Tilt-compensated compass application? When checking the 'Applications' in datasheet, 'Tilt-compensated compasses' is not mentioned in the datasheet of ISM303, but it is mentioned in the datasheet of LSM303, which are both '3D accelerometer + 3D magnetometer' ICs. Can someone share your comments on what the difference would be in ISM303 vs LSM303 for computing tilt compensated compass values?Can we use the raw accelerometer and magnetometer data from ISM303 and compute tilt compensated compass values? Is there a library provided by ST for computing the Tilt compensated compass reading / is there an application note suitable for ISM303 for computing tilt compensated heading (just like the application note for LSM303)?ThanksAkshay

Hi,I'm trying to configure an LSM6DSO (sparkfun breakout), using a TWIM/I2C bus, master device is a nordic NRF52.For the most part, the communications appear to be working. I'm able to configure an interrupt to respond to a single tap. The interrupt works. So it would appear communications and hardware layer problems are not the issue and the chip is working (but only just!).My key problem is that when i write to certain registers, and read the values back, i get totally different values.An example is TAP_CFG0 when i write 0x45 to this (latching interrupts, y axis turned on) it reads back 0xFF ! which is mad, as the datasheet suggests the msb should ALWAYS be 0?What could cause this register to throw up some sort of error value or bad return value? I can find no useful documentation of this in the datasheet?Also, i tried to perform a reset, by setting the SW_RESET bit, (with acc & gyro in pwr-down mode), yet the bit never resets itself to indication completion of reset. Could the t

The RFAL library claims to support the ST25R3912 but has no definitions in the sources for this chip. How to use the RFAL library with the ST25R3912 chip? just use ST25R3911 definitions and sources?

Hi,I have a small problem during stm32mp1xxx bring up. The Uart4 is debug console and is connected to stlink v2.1 on virtual serial. The problem is that this stlink makes all the time interrupt U-Boot and stack in it (stlink not connected to USB). To go system father I need to connect stlink to USB and type 'boot'. I tried to addCONFIG_BOOTDELAY=-2 CONFIG_SILENT_CONSOLE=y CONFIG_SYS_DEVICE_NULLDEV=y CONFIG_SILENT_CONSOLE_UPDATE_ON_SET=y CONFIG_SILENT_U_BOOT_ONLY=ybut without success.In the hardware, I added pull up resistorsTo prove my theory I make a shortcut on resistor R58 and the system boot-up all the time.How to correctly resolve this problemThanks in advancedBR Michal

Hello,I cannot use the STM32CUBEprogrammer standalone program, however my programmer works just fine with stm32CUBEIDE V1.7. During programming in STM32cubeide the configuration is visible and it loads STM32cubeprogrammer V2.8 I copied the settings over to the standalone program since those seem to work in STM32CUBEIDE but it still does not work. I updated to the latest firmware and tried out both V2.9 and V2.8 of STM32CUBEprogrammer but neither works.

Hello, I have found out that connection from transceiver pins CAN_RX and CAN_TX are connected to CAN_TX and CAN_RX.I mean :from CAN transceiver to stm32f105CAN_RX -----------------------------> CAN_TXCAN_TX------------------------------> CAN_RXIs there anyway to fix the issue in software?Thank you.

Hello, is there a way to calculate and display the flash/memory checksum after build for example in MPLAB X IDE there is a checksum in the dashboard (see the attached picture).

Hello,I have stm32h757i-eval board here. I've used stm32cubeprogrammer to edit OB where I've unselected M7 core from booting and left just M4 selected. This was done in intention to boot just M4 core and leave M7 core halted.When I modified OB this way and then apply, after few seconds I got a message that CubeProgrammer is not able to connect to the target. I've tried again stopping and starting CubeProgrammer and it crashed clearly (ubuntu 20.04, cube programmer 2.9.0, known issue). I've found a solution for crash, installed 2.10.0 on ubuntu 20.04) and attempted to connect board again and in the log (no crash) I see "Error: No STM32 target found!".I've decided to duplicate the issue on Windows 10 + STM32CubeProgremmer 2.10.0 and again I see the same error.Whole log on Windows looks: 21:26:28 : STM32CubeProgrammer API v2.10.0 | Windows-64Bits 21:26:28 : ST-LINK error (DEV_CONNECT_ERR) 21:26:40:995 : STLinkUSBDriver.dll loaded 21:26:40:997 : STLinkUSBDriver.dll loaded 21:26:40:997

Hi,Iam student on Sheffield hallam university an​d I called by sulaiman Alsaffar discover bug when working on stm32f407 discovery board. This bug set the 5v for the vbus low which make it unactive in patch 6.4.0 .I had to read all folder that generate by the mx usb drive to fix this problem since it wont let you use usb because it wont get enough voltage and it not mentioned anywhere and wasn't there before. ​Fixing the issue with USB MSC The USB Mass Storage Class was not working because of insufficient voltage supply toVBUS. It was figured out that the usbh_platform.c file generated by the CubeMX software washaving issues.By making necessary modifications, the expected outcome was obtained.Before fix/***@brief Drive VBUS.* @param state : VBUS state* This parameter can be one of the these values:* -1: VBUS Active* -0 : VBUS Inactive*/void MX_DriverVbusFS(uint8_t state){uint8_t data - state;/* USER CODE BEGIN PREPARE_GPIO_DATA_VBUS_FS */if(state == 0){/* Drive high Charge pump */data -

Hi,I am trying to use malloc() in BlueNRG LP as I want to dynamically allocate some memory during runtime (not frequent, only when a set of commands are received via BLE). However, I am not able to allocate memory. The pointer always is returning NULL. I have set the Heap scheme to "Advanced" under project options in IAR Workbench, but am not able to allocate.char * ptr = (char*)malloc(5 * sizeof(char));if (ptr == NULL) return;The above is a code sample. I tried printing the size of character, it returns a huge garbage value for some reason.Any help would be appreciated, thanks!

In examples I got familiar with RF low level access is controlled by some exact coprocessor firmware. Existing coprocessor binaries provide some higher level of abstraction that seems to not include forcing signal with exact characteristics. Do I missing something or is there any other approach to start continuous signal generation with specified power and frequency?

Hi, I dont know how this happened, but my Eval board STM32H757 can not go after :SystemClock_Config() ==> HAL_PWREx_ConfigSupply() ==> while (__HAL_PWR_GET_FLAG (PWR_FLAG_ACTVOSRDY) == 0U)The progam stay in the while loop : while (__HAL_PWR_GET_FLAG (PWR_FLAG_ACTVOSRDY) == 0U)from what I see, the  MODIFY_REG (PWR->CR3, PWR_SUPPLY_CONFIG_MASK, SupplySource);doesn't modify SMPSEN or LDOEN. They are bot to state "1". In the datasheet ( with STANDBY =0 and SMPSLEVEL =0 ), it is an illegal setup:"Illegal combination, the default configuration is kept. (writedata will be ignored)."the Programm is directly outputed from cubemx ( default perepheral setup )So I am stuck here, and I dont know how to move forward.Does anybody know the path to recover this?Thank you

Hi, I want to use B-U585I-IOT02A as a controller for mobile robot, I use a smartphone for the remote control. For now I am using HC-05 as the bluetooth interface because I can't find out how to program the STM32WB5MMG to act similar with HC-05. Can anyone give me any guide or reference how to do it? I just need it to work as the bluetooth interface to receive serial data and send it to the STM32U585.And I use MITAppInventor 2 to create the smartphone software if anyone wondering.

Sorry for my silly questions ,but i am having a hard time understanding the exclamation marks in cubeMX .if somebody could please guide me here .it will be much appreciated.Example:the RCC is shown as partically disabled.i have use LSE (crystal/ ceramic Resonator ) as a mode However i should be able to use it.and i get this warning (statut: partly disabled conflict USART2 asynchrone).Exemple2:i want to use USART2 and configure PA as GPIO-EXTI (INTN DIR for my sensor TDC_GP30 pin name (pin 22)) is that possible or not ??
