STM32 MCUs Wireless

Upon triggering a notify event calling the following function "Custom_STM_App_Update_Char()", the STM32 successfully sends data, which I receive on my iPhone using ST BLE Toolbox. However, after that, the STM32 becomes unresponsive to further BLE requests. I can see that the system hasn't crashed, as it is continusouly calling "UTIL_SEQ_Idle".I am using a BLE application: server profile with a custom profile. I have already seen the other forum post titled "STM32WB55 Stops handling events after sending a notification" which sounds similar to this, but I am not deliberately pausing or stopping the sequencer at any point (as far as I'm aware).Another unusual thing I've noticed, is that every other characteristic has been given a handle for the function "Custom_STM_Event_Handler(void *Event)" in "custom_stm.c", which I am able to use to call other functions to handle thos events, however, for my notify event, I can only see handles for NOTIFY_ENABLED_EVT / NOTIFY_DISABLED_EVT which aren't

Hi, I developed an application using the stm32wb5mm-dk. Everything works until I try to use an external 5V power supply. In fact, I change the position of JP2 on position 7-8 (to select 5V EXT) and I soldered SB4. However, when I supply the board through CN8, LD2 is on, JP1 is at 3.3V but the application on the STM32WB seems not to being run. If I provide power also through the USB STLK, it seems to start running. Is there any other JP or SB to adjust for extenal 5V supply?Thanks. 

Hi,i am working with BLE_p2pServer_ota example as a template and i want to send 5 Bytes of data from the client (nRF Connect App on the cellphone) to the server (NUCLEO-WBA55). However, I am having trouble receiving more than 2 bytes.1. I made a new characteristic in CubeMX with a value length of 5 bytes and i set the length characteristic to variable because i want to send also less then 5 bytes: 2. I started the debugger and set a brakepoint in p2p_server_app.c:3. I checked the transmitted values in expression view:Everything seems to be fine up to this point.But when I try to send 3, 4 or 5 bytes, nothing happens and the program does not stop at the breakpoint. It seems that the change to 5 bytes was not reflected in CubeMX.And when I look at the function aci_gatt_add_char() in the file p2p_server.c, I find here in the 4th argument SizeUart_C which has the value 2: /** * UART_C */ COPY_UART_C_UUID(uuid.Char_UUID_128); ret = aci_gatt_add_char(P2P_SERVER_Context.P2p_serv

Hi,in my low-power STM32WL55 application I would like to use the LPUART to receive data (no transmission) while the device is in STOP2 mode. I have two questions about this:The reference manual states:"Before entering low-power mode, make sure that no LPUART transfer is ongoing. Checking the BUSY flag cannot ensure that low-power mode is never entered when data reception is ongoing."Then how do I check for an ongoing data transfer? The external device connected to the LPUART sends data "spontaneously" so I can't control when this happens, there might be a byte arriving just when I'm entering STOP2 mode. What happens if a reception is ongoing when the device enters STOP2 mode?I would like to use the HSI oscillator for LPUART reception in STOP2 mode (automatically turning it on when needed). But I would also like to use MSI after wake-up in order to get better flexibility for the CPU frequency (achieving frequencies > 16 MHz, or achieving lower power consumption) by setting STOPW

Hello... Here I am developing a battery based IOT-STM32 based project and I am unable to read and write ADC using this new chip STM32WL5MOCH6S. Please provide me any detailed document related to ADC or Any kind of example code which I can check in my Microcontroller. Thanks & Regard

Hi,   I am developing on the Nucleo-wl55jc2 development board and I am trying to program the sub-GHz radio to transmit a continuous wave (not sending data packets, just a waveform). I have attached my code below along with a zip of the project. This code has been simplified from the 'SUBGHZ_Tx_Mode' example program that can be generated using the example selector when generating a new project.   I have tested both the 'SUBGHZ_Tx_Mode' example program and my code with a spectrum analyzer and a software-defined radio, and have not been able to pick up a transmission on either.   Any help is appreciated.   - Kevin #define RADIO_MODE_STANDBY_RC 0x02 #define RADIO_MODE_BITFIELD 0x70 uint8_t RadioCmdSetFreq[4] = {0x1D, 0xCD, 0x65, 0x00}; // 500,000,000 uint8_t RadioResult = 0x00; uint8_t RadioParam = 0x00; uint8_t RadioMode = 0x00; uint8_t RadioStatus = 0x00; int main(void) { HAL_Init(); MX_SUBGHZ_Init(); /* Set Sleep Mode */ if (HAL_SUBGHZ_ExecSetCmd(&hsubg

I'm trying to use STM32WB09KE for the BLE application. However, unlike STM32WB55, this microcontroller must activate PKA and RNG for the BLE module.So, I did.However, after generating the BLE code, I tried to build the project in the IDE and it showed a lot of errors related to RNG part.For example, these functions are not found in the project.HW_RNG_Init()blue_unit_conversion()PKAMGR_Init()aci_gatt_srv_profile_init()NVMDB_Tick()NVMDB_AppendRecord()NVMDB_ReadCurrentRecord()NVMDB_CompareCurrentRecord()NVMDB_DeleteRecord()Osal_MemCpy()GetPartInfo()HW_AES_Encrypt()HW_RNG_GetRandom16()HW_RNG_GetRandom32()RADIO_GetMaxPALevel()RADIO_GetDefaultPALevel()RADIO_SetHighPower() Do you have any idea why my IDE cannot import some files related to this?My cubeMX and cubeIDE are latest version.

Hi,i use the example ble_p2pServer_ota with STM32WBA55. How can i send a value (uint_8 or a string) from the server (NUCLEO-WBA55) to the client (Cell Phone)?Here in the example code (file p2p_server_app.c), the value of Switch_c_NOTIFICATION_ON for example is 1, but this is an enum and is used as a flag. I want to send an uint_8 or string value from a Sensor. How can i do this?case P2P_SERVER_SWITCH_C_NOTIFY_ENABLED_EVT: /* USER CODE BEGIN Service1Char2_NOTIFY_ENABLED_EVT */ P2P_SERVER_APP_Context.Switch_c_Notification_Status = Switch_c_NOTIFICATION_ON; // send the value 1 LOG_INFO_APP("-- P2P APPLICATION SERVER : NOTIFICATION ENABLED\n"); LOG_INFO_APP(" \n\r"); /* USER CODE END Service1Char2_NOTIFY_ENABLED_EVT */ break; case P2P_SERVER_SWITCH_C_NOTIFY_DISABLED_EVT: /* USER CODE BEGIN Service1Char2_NOTIFY_DISABLED_EVT */ P2P_SERVER_APP_Context.Switch_c_Notification_Status = Switch_c_NOTIFICATION_OFF; // send the value 0 LOG_INFO_APP("-- P2P APPLICATION SERVER : NOTIFI

Hi,I am working with the ble_p2pServer_ota example with an STM32WBA55 controller.If I want to send data (one byte for example) to an app on a cell phone, what settings do I have to make in the characteristics in CubeMX? 

Hi ,Regarding working with the STM32WLE5 with SUBGHZ block in the CUBE-MX.in the clock section tab in the CUBE-MX I dont see any mention of the RF-PLL clock. if i understood correctly - in order to work with the LORA SUB-GHZ BLOCK i need to supply a 32 Mhz HSE clock . I dont see in the clock section tab in the CUBE-MX any mention of this "must -have" 32 mhz HSE clock . it seems any clock source is possible and any frequency is possible .Does the clock section tab in the CUBE-MX dont represent the CLOCK tree in  the STM32WLE5 ? I see this issue even when I open example code for sughz block within the CUBE-MX.  Thank you,Viola

Hi,I am using Zigbee_OnOff_Router_NVM to test the opening and closing function of IasZone Server. I found that by default, the notification generated by modifying the status value is 'Report Attributes'. But according to document 'Zigbee Cluster Library', a 'Zone Status Change Notification Command' should be generated.I also found that if the following code is commented on, it can generate the 'Zone Status Change Notification Command' notification correctly, but the status value will lose persistence.  /* Allocate the attributes */ // if (ZbZclAttrAppendList(zigbee_app_info.iaszone_server_1, zcl_iaszone_server_attr_list, ZCL_ATTR_LIST_LEN(zcl_iaszone_server_attr_list))) // { // ZbZclClusterFree(zigbee_app_info.iaszone_server_1); // return ; // }  I want to know how to generate 'Zone Status Change Notification Command' notifications while enabling data persistence.I provided the source code I used. ThanksDL_Weng

Hi,I hope everyone is fine.I have question about Inheritance Certification.The Thread Group says;The Thread Group allows certification by inheritance for families of end products that reuse the same Thread system (chip and stack) and the same use cases.When appropriate stack libraries and SOC or module used End Device Certification can certifiable by Inheritance. Our company does not have any Thread or Matter-certified products, but if we use ST's certified module and stack library, can we obtain Thread certification for an end device we develop?Can we use the certification by inheritance feature when using ST's modules?We want to use a Matter-enabled module and a certified stack binary in our projects; however, we will design a PCB using this module.We would like to confirm whether soldering components onto the PCB with the module or chip would invalidate the certification by inheritance. We would greatly appreciate your support with your experience and knowledge.

Hi,i am working with NUCLEO-WBA55 and using the BLE_p2pServer_ota example as a template for my project.Unfortunately, the program does not start when I supply it with power via USB but only after I have pressed the Reset button. Can someone please help me?

Hello,I have an STM32WB and I am trying to get the data from some pressure, temperature and humidity sensors through DMA and send them to my Android via BT, while at the same time saving it as well on a SD card with SPI. Both programs work quite well separately, both for SD and for BT (I used the Hands On from STM where you send random temperature data to the app) , however when I put them together neither of them works. Here I think I lack the knowledge of setting the Clock Source. For my SD card and receival of sensor data I normally use the PLLCLK with 32Mhz on CPU1 and 16Mhz on CPU2. However for the BT app I used the HSE_SYS clock source with both CPUs on 32Mhz,I can't seem the wrap my head around how to set the clock in order for both these functions to be able to work together.Also as a second question would be how do you suggest to implement the two functions in a same program? I want the data to be transmitted simultaneously via BT while also storing the same sensor data on the

How to port BLE Mesh Lighting application SW for BNRGLP into STM32WB09?

In order to test the BLE performance of the STM32WB55CGU6 in STM32CubeMonitor-RF, I downloaded the BLE_TransparentMode program onto the STM32WB55CGU6. However, I did not notice that the pin configuration of this program did not enable Serial Wire. The pin configuration is shown in the image.This has resulted in a problem: I am unable to connect the microcontroller to STM32CubeProgrammer, Keil, or other software via ST-Link. I have also tested the UART and USB connections in STM32CubeProgrammer, but they also failed to connect. What should I do to resolve this issue?

 Hello,Recently, I have been working with the SensorTile module (STEVAL-STLCS01V1) featuring the STM32L476JG and BlueNRG-MS. I successfully created standalone HID devices for both keyboard and mouse. However, when I attempted to implement a composite HID device, the computer failed to recognize it properly.I would like to know if BLE supports HID composite devices.Could you provide some guidance or suggest possible solutions? Thank you! I will paste my hid_report_map below.    /* USER CODE BEGIN PV */ #define FEATURE_SUPPORT_MULTIMEDIA_KEYBOARD 1 //composite hid #define use_mouse 1 #define use_keybord 1 #if FEATURE_SUPPORT_MULTIMEDIA_KEYBOARD #define HIDS_KB_REPORT_ID 0x01 //0x01 #define HIDS_MM_KB_REPORT_ID 0x02 #endif static uint8_t hid_report_map[] = { #if use_keybord 0x05, 0x01, // USAGE_PAGE (Generic Desktop) 0x09, 0x06, // USAGE (Keyboard) 0xa1, 0x01, // COLLECTION (Application) #if FEATURE_SUPPORT_MULTIMEDIA_KEYBOARD //composite hid // 0x85,

Hello,Can someone please provide a working download file for "STM32Cube function pack for STEVAL-PROTEUS1 sensor datalog and file transfer over BLE and USB"?The ZIP-File Version 1.1.0 is corrupt.It cannot be extracted neither on Windows, Linux or Mac.To be honest it's possible to extract under Linux.But the archive just contains 82 files instead of 2408 files like in Version 1.0.0.Thank you.

HelloFor now, I have a Bluetooth application that sends data through a custom app with notify.I see my device on the ST bluetooth tool box with my data.However, to update my application, I want to send data only if I am correctly connected to my phone to not miss data.I tried to work with aci_hal_get_link_status() function but the status stay at 0. Here's a snippet of my code : uint8_t link_status = 0; uint16_t link_connection_handle = 0; aci_hal_get_link_status(&link_status,&link_connection_handle); main_CreateBufferBle("color:red\n size:1.5\n length:100 \n",0,count); Custom_APP_Send_Data(0);  So I do see the data on my phone but the link status and link connection handle stay at 0. I haven't found an example of using this function so I might use it wrongly.Kind regards,Pierre Lobert

Hello,When activating STM32_WPAN in STM32CubeIDE for STM32WB, the prescaler of RTC is forced to CFG_RTC_ASYNCH_PRESCALER (value is 15) and CFG_RTC_SYNCH_PRESCALER ( value is 0x7FFF ).I am used to configure RTC on other STM32 products with 127 and 255 values.During test, I see that the RTC is running ~ 16 times to slow. Do I miss something?Is this problem similar to point 2 of the question "STM32WB - Problems with BLE and RTC" from "MLind.2" on 2020∕05∕25?Thanks for helpBest regardsPaul

Hello,I am trying to put the Lorawan keys (DEVEUI,APPEUI, APPKEY) from a serial terminal using uart communication for end node application. I am using uart interrupts for this. There is cubemx generated usart_if.c file which contains HAL_UART_RxCpltCallback() already. This is the code snippet: void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { /* USER CODE BEGIN HAL_UART_RxCpltCallback_1 */ /* USER CODE END HAL_UART_RxCpltCallback_1 */ if (huart->Instance == USART2) { if ((NULL != RxCpltCallback) && (HAL_UART_ERROR_NONE == huart->ErrorCode)) { RxCpltCallback(&charRx, 1, 0); } HAL_UART_Receive_IT(huart, &charRx, 1); } /* USER CODE BEGIN HAL_UART_RxCpltCallback_2 */ /* USER CODE END HAL_UART_RxCpltCallback_2 */ }  How to modify this with my code so that I can receive a command from serial terminal and proceed accordingly. Thank you.
