I was a bit surprise if I read a characteristic witch is more 22 bytes long it conduct to more than one read permit events on server-side and as many read response on client slideit's surprised me because limit carac buffer length is 250 byte max in config by defaultis there a way to enlarge this ?? (server or client side or both ?)it would not a be a big deal if I can determine on server-side when carac is completely red but I can't get any idea where reading is regarding total bytes size of CARAC according to § 4.7.6 Evt_Blue_Gatt_Read_Permit_Req in https://www.st.com/content/ccc/resource/technical/document/user_manual/6d/a1/5b/6c/dc/ab/48/76/DM00162667.pdf/files/DM00162667.pdf/jcr:content/translations/en.DM00162667.pdf the event message should be grouping but in stm32wpan middleware core ble_def.h message structure dont include datalen and it looks that length of encapsulating message is sized accordingly typedef __PACKED_STRUCT { uint16_t Connection_Handle; uint16_t

Hi developers.I have the same issue as many others, which has been posted already 4-5 times and marked as "solved" in some of them, but it is not at all the case.The CubeMX on launsching shows the first screen (splash) and then disappears.It worked a couple of times after intallation, then again after de-installation/reboot/re-installation/reboot.Watching the Task-Manager it shows a process called "OpenJDK Platform binary" which starts at high CPU and ends up to 0% but with around 200MB RAM reserved. And this can take place many times, collecting a bunch of idle/useless processes. I run it with Windows 10, latest version of JAVA and CUBE at this moment, but with a previous version on both I used to have the same issue.While unistalling, I try to find every single file I can, so that I delete each trace manually, but every time I re-install it, it still "knows" which was my last opened projects and which uC I use. Maybe ST can see it a bit seriously the topic. I suppose I am not th

I was trying to write a small firmware to keep the LD9 Orange LED steady ON, instead of blinking in STM32CubeIDE. I could able to flash into CM33 core using the debugger and able to debug. When I disconnect debugger, it still remain ON.But once I reset the board, the CM33 firmware is gone and LD9 again started blinking, as if my firmware is over written.Any solution?

Hi all,I am looking for advices to implement my GUI.  I have screen 1 with all the widgets. On this screen by default has:1. The texts for Hours:Minutes:Seconds and a button to switch to setting screen to set the count down timer.2. The switch mode button, to switch the timer 1 to timer 2.Timer 1 has different texts and looks vs. timer 2.The rest of the widgets on screen 1 stay exactly the same.Currently, I have a solution buy copy exactly the same screen 1 and just replace the timer texts and button only, and using switch mode button to switch back and forth the screen 2 to screen 1 and vice versa.I found this is wasting the memory resource and additional coding to handle different screens.Question:Is there a way I can use only screen 1 and change texts and button between timer1 vs. timer2?

Hi,I'm currently working with the STM32G491RET and using the NUCLEO-G491RE evaluation board. I need to check whether the device enters boot mode using the BOOT0 pin and NRST. From my understanding, to enter boot mode, BOOT0 should be driven low, and NRST should be toggled (low to high). I connected the board to my PC via USB (ST-LINK) and tried entering boot mode, but it only resets the board and restarts the existing program, printing debug logs as usual. Initially, JP3 (which connects the ST-LINK reset to the MCU reset) was shorted. The hardware team has now removed that connection. After this change, when I attempt to enter boot mode, no logs are shown. How can I confirm whether the device has successfully entered boot mode?One more clarification is needed. If i get a fresh board, just BOOT0 pin and NRST enough to enter bootmode?

Hi,I'm curently working on a STM32H745i-disco and need to implement a uboot on it. It doesn't seem to be natively supported. I would like to know if there is a port on going or at least if you have somewhere the linux/uboot device tree for this board. Found it for Zephyr but not Linux / uboot.Thanks in advance.

Hello, I’m exploring how to convert the  PROFINET Community Stack into a working implementation on STM32.Specifically, without relying on commercial stacks like RT-Labs.Has anyone successfully ported the community stack to an STM32 platform? Any insights, examples, or guidance on integrating the stack with STM32  would be very helpful.

Hi,I am trying to check if a button is pressed for 3s continuously using a timer which is started through an interrupt. The code for the same is attached below. The issue I am facing is the interrupt is immediately called when I press the button after reset, but it works fine for the consecutive times. void EXTI1_IRQHandler(void) { if (__HAL_GPIO_EXTI_GET_IT(RESET_Pin) != RESET) { __HAL_GPIO_EXTI_CLEAR_IT(RESET_Pin); // Clear the interrupt flag if( HAL_GPIO_ReadPin(RESET_GPIO_Port, RESET_Pin) == 0){ //FALLING Edge HAL_TIM_Base_Stop_IT(&htim2); }else{ //RISING EDGE if(!(TIM2->CR1 & TIM_CR1_CEN)){ __HAL_TIM_SET_COUNTER(&htim2, 0); HAL_TIM_Base_Start_IT(&htim2); } } } } void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { /* USER CODE BEGIN Callback 0 */ /* USER CODE END Callback 0 */ if (htim->Instance == TIM8) { HAL_IncTick(); } /* USER CODE BEGIN Callback 1 */ if(htim->Instance == TIM2){ HAL_TIM_Base_Stop_IT

Hello everyone,I've been struggling with the ADC of a STM32G474QE on a custom board for some while now. I initially saw a discrepancy between an onboard NTC thermocouple and its measured ADC value. The measured Value (calculated to mV) was off by an average of 50mV over three boards. The impedance of the NTC circuit is reasonable low with 500ohm, which should result in no issues with this rather infrequent measurement with a a high sampling time. I then started seeing more of that behavior with other ADCs and their respective channels. There was always some offset in the measurement. To be able to quantify the offset, I ran a test, where i applied a dc voltage to the other channels, measured the voltage at the pin and compared it to the ADC values. (see attachment meas offset.png). I had very similar behavior on several boards. I then looked into ways to compensate this and started to implement measurements to Vrefint as injected samples after rerunning the ADC-calibration. (

I am working on a STM32N6570-DK board, and I am wondering how to start the MPU of the N6 core, when I start a touchgfx project, it can't work successfully. I hope that some additional information and some courses can be provided.

I am working on a STM32N6570-DK board and I noticed that the CN7 of the board can be modified as digital I/O pin or an ADC. So I want to make sure that when I use the A1 port of CN7 for example, and I want to use this port as a usart_tx. Then I can directly enable the PC10 as a usart_tx and disable the PA9 right? And I want to make sure that the modification don't damage the ADC function of PA9, since the MCU actually accept 0-1.8V and the 3.3V is too high.

Hello , everyone. I am currently working with the STM32N657X0H3Q device on the NUCLEO-N657X0-Q board.Following the official Template_FSBL_LRUN example, I successfully generated and signed both FSBL and Appli binaries using STM32CubeIDE and STM32_SigningTool_CLI v2.19.0. In DV Mode (BOOT1 = High), I programmed:The trusted FSBL binary to address 0x70000000The trusted Appli binary to address 0x70100000 After programming, I set the BOOT1 jumper back to low (BOOT1 = 0) to boot from external XSPI Flash.However, after reset, the board appears unresponsive — no LED blinking or visible activity from the Appli. As suggested in the documentation, I have enabled the NO_OTP_FUSE preprocessor macro in the FSBL project. I would appreciate your help in identifying why the application does not execute after the FSBL handover. You will find

Hi, I am using STM32F446RE Nucleo and a Peak CAN Usb to test the CAN functionality of the microcontroller. I have connected the Microcontroller to a CAN Transceiver (TJA1050) and added a 120ohm resistor between the CANH and CANL line. I have attached the config of the CAN hardware below   hcan1.Instance = CAN1; hcan1.Init.Prescaler = 42; hcan1.Init.Mode = CAN_MODE_NORMAL; hcan1.Init.SyncJumpWidth = CAN_SJW_1TQ; hcan1.Init.TimeSeg1 = CAN_BS1_2TQ; hcan1.Init.TimeSeg2 = CAN_BS2_1TQ; hcan1.Init.TimeTriggeredMode = DISABLE; hcan1.Init.AutoBusOff = DISABLE; hcan1.Init.AutoWakeUp = DISABLE; hcan1.Init.AutoRetransmission = DISABLE; hcan1.Init.ReceiveFifoLocked = DISABLE; hcan1.Init.TransmitFifoPriority = DISABLE;   When I transmit a message using the Peak CAN, I get  "Frame stuff error (Rx)". I have already attempted to Change the baud rate Remove the resistor Tried a different Peak CAN Changed the Transceiver (3 times)   Is the issue from the Transceiver or t

Hello, I want to buy STEVAL-WLC38RX product..I can't sell it online.. may I know where I can buy it?

Hi guys,I'm working on a pretty simple cable replacement client/server program to exchange data form one device to another.When I enable traces in CubeMX for the WPAN/BLE part, my STM32WB5 is visible (I can see it from my phone or using a Nordic USB Dongle, connect to it and exchange data). All traces go to USART1.Then, since everything works, I disable traces (CFG_HW_USART1_ENABLED to Disabled, CFG_DEBUG_* to Disabled, BLE_DBG_APP_EN to Disabled, etc.). At this point, I can't see anymore my device in the phone list even tough aci_gap_set_discoverable returns 0.I don’t understand how disabling traces can prevent the rest of the BLE stack from running.Any help on this would be appreciated.Thx !

Hi all,Could you show me the temperature accuracy of LIS2DW12 ?Thanks all,

When evaluating the st25R3916b chip using the X-NUCLEO-NFC08A1 development board, we found that the current reached about 100-150ma during the nfc reading and writing process. However, we did not find the standard value for this part of the current in the manual. May I ask if there are any official typical current values for this chip or development board during nfc reading and writing for our reference? What is the minimum current that this chip can achieve when reading and writing in nfc?

I want to use the PM8805 as POE controller in a custom project for a 25W classified POE device. The PM8805 should generate the input power for 2 boards in this device.However, when connecting only one board with approx. 30uF input capacitance, the power supply works without any problem. But when connecting the 2nd board with approx. 20uF additional capacitance, the power supply fails and the PM8805 is in a state, where it tries to switch on repeatedly and gets certainly hot. The POE LED on my switch is constantly lit in this situation.My understanding of this behaviour is that it is caused by the overall inrush current out of the PM8805 into the 2 boards!?To be able to develop an inrush current limiter without using the "real" boards, i bought a STEVAL-POE001V1 which i got on my table now.Connecting the STEVAL-POE001V1 to my little POE-switch (TL-SG105PE) without any load makes the power-LED (D2 - blue) blinking with approx. 1s interval and so the POE-LED of my switch. (With a mul

Hi, I am new for ST, currently I am build the data logger for power monitoring which is used the M95P32-I to store log data and ESP32S3 is used to process data received.Can I know there have any guideline or source code for this M95P32-I EEPROM for some configuration, write and read data? 

I am confused about the limits of the FT pins on this MCU. I think I understand the maximum voltage on an FT pin except FT_c is Vdd + 4V as long as no pulls are enabled. So with 3.3V Vdd the max voltage on most FT pins will be 8.3V is that correct? Its a bit confusing where that footnote is placed.Beyond that, given the voltage limit is 8.3V how does it matter if the positive injection current limit is 0mA? That means I need an infinitely large resistor to prevent any injection current when the voltage is over Vdd. Or does N/A mean there is no current limit so long as the voltage is not exceeded?Thank you.

Is the internal bootloader on the STM32H723 DO-178 certified?   It just dawned on me that the whole line of CPUs might be disqualified for aircraft use because the bootloader code "flies" with the aircraft and all such code must be certified to the level declared by the system (DAL levels A-D).   Do you have avionics customers that use these?  Can the bootloader be erased?Regards,Mark
