STM32 MCUs Wireless

I have successfully adapted On_Off Zigbee examples for my project. Both router and coordinator works well together. However, the router cannot pair with other coordinator (standard coordinator for Zigbee2mqtt ).I am new for Zigbee. Please give me some hints. Thank you very much for your kind support.

SBSFU 2.4.0 initializes CPU2 in all cases (for a good reason, locking the AES Key used for decryting the firmware image(s) )When trying to set a HSE tune value (neccessary for proper Bluetooth connectivity) in the application (and also in my loader), the procedure hangs on stopping HSE and waiting for the HSERDY bit to become reset.I tracked it down to the very moment the PWR->CR4, PWR_CR4_C2BOOT is set. The HSEON bit is not set at any time I could observe it. From RM0434: "This bit cannot be reset if the HSE oscillator is used directly or indirectly as the systemclock."So while HSERDY is set after C2BOOT i can still set HSEON to 1 and 0 as I wish (without influence on HSERDY). Only after I select HSE as a system clock source, I can't reset HSEON anymore. This lets me believe that the HSERDY bit staying on is indeed a bug, and not caused by it accidentially being selected as a clock source.Does CPU2 / BLE Wireless Stack initialize HSE? Why does it make HSERDY stick to be SET? Is it

Hi.I'm wondering about discrepancies in antenna dimensions between AN5129 application note and the actual board - Nucleo MB1335. As you can see the differences are subtle but visible. I'm mostly curious about why the antenna width varies? Widths at different spots I was able to measure: 0.4mm, 0.425mm, 0.45mm, 0.475mm, 0.5mm.Also, the gap between parallel arms varies between 0.725mm and 0.75mm, which is different than 0.8 specified in the app note.Is there a reason for that or is it simply a mistake while doing a layout? I can see that the antenna wasn't defined as library component but rather drew as a polygon.

Hello! I'm working with an STM32-WB55 nucleo board and trying to put the board into sleep mode. In trying to plan the clocks, I've been working with the *.ioc file to figure out a way to make it work so I know what clock settings to use to put in in low power sleep mode (which requires a sysclk of under 2 MHz). I have two basic problems:1) If I get my sysclk down below 2 MHz, I get a warning with HCLK1 (which has to be over 14 Mhz, according to the framework)2) I'm not sure if my proposed solution to get down to 2 MHz is the best approach (it looks like it will work but wasn't sure if this is the best approach)I'm going to attach my current setup:Here is the generated code:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};   /** Macro to configure the PLL multiplication factor */ __HAL_RCC_PLL_PLLM_CONFIG(RCC_PLLM_DIV2); /** Macro to configure the PLL clo

Using the STM32 Nucleo WB55. Struggling with the OTA examples. None of the three OTA examples seem to work for me. When I program the non-OTA version, the device starts advertising and I can connect to it. But with the OTA version, I see no advertising packets and the power usage shows no network traffic.

These are my error messages - <command-line>:0:1: error: macro names must be identifiers<command-line>:0:1: error: macro names must be identifiers<command-line>:0:1: error: macro names must be identifiers<command-line>:0:1: error: macro names must be identifiersmake: *** [Utilities/subdir.mk:35: Utilities/queue.o] Error 1make: *** Waiting for unfinished jobs....make: *** [Utilities/subdir.mk:33: Utilities/low_power_manager.o] Error 1make: *** [sx126x/subdir.mk:23: sx126x/sx126x.o] Error 1make: *** [sx126x/subdir.mk:21: sx126x/radio.o] Error 1

Hello,Can I use STM32WB as master/slave at the same time? Our project requests the product to talk with cell phone and other accessories at the same time. If so, is there an example I can refer to?Thank you very much!

CUBE and MX do support STM32WL CPU's *but not* the above mentioned development board. So we need eitherdetailed instruction how to setup the IDE to work with the board ora link to an updated version of one of these IDE's.Question is related to Cube 1.4.2 / MX 6.0.1Thank you.

Hello,I'm trying to get the advertising state from a new Cube MX project.I followed the step by step, did all the initializations and compare with the P2Pserver exemple.Everythings seem to be ok but I can't get this state work.It seems that the program stay blocked (Program received signal SIGINT, Interrupt.) in infinite loop when it tries executing SCH_Run() for the first time .The IRQ occurs just after the "SuperMask &= mask_bm;" line in SCH_Run()Because of that, the program doesn't execute APP_BLE_Init( void ) and I can't get the advertising state, so the program doesn't go into the round_robin loop. It is as if "SCH_RegTask( CFG_TASK_SYSTEM_HCI_ASYNCH_EVT_ID, shci_user_evt_proc );" in "appe_Tl_Init()" didn't register the task well.Thanks you for helping me.

Good DayI am programming a stm32wb55rg to start upDo some ADC samplingStart up BLE using    APPE_Init(); Load all values in characteristic.And then i sit in loop running:UTIL_SEQ_Run( UTIL_SEQ_DEFAULT );After 60 seconds I put device in standby mode. I am happy using standby mode and have device have to reset completely when wakeup. I Use a check on power up to see if device is woken up from standby,   NVIC_SystemReset();     The device works great and my standby wakeup is RTC clock for 15 minutes.I also want to wake up device using wakeup pin 3.I have a 100k external pull down resistor on this pin.When I use a bare program wakeup pin works 100%As soon as i add UTIL_SEQ_Run( UTIL_SEQ_DEFAULT ); to my while loop , wakeup pin does NOT wake up mcu anymore. While RTC wakeup from standby works.Here is my standby code ,partly taken from standby example:/-------------------------   /* The Following Wakeup sequence is highly

I need to select a chip that offers me a BLE 5.0. What is the advantage of using STM32WB chips, rather than using other modules like Telit, Ebyte etc. Okay STM32 has CubeMX and easy implementation just as said in application notes, workshops etc. but in forums, people are complaining about how to make a simple custom BLE service on later firmware packages. What is ST's strategy? While there are a lot of modules that have bunch of "beginner" application notes and simple USART protocol, why would I select STM32WB?Just asking for company. No offense, big fan of ST.Thanks.Edit: The project that I'm working on is now divided into two ways: I will choose STM32WB or, standard STM32 chip + BLE module.

Hi all,I am looking for a library use with B-L072Z-LRWAN1 for Lora comm between two kits. Is there any library for this including only Lora libraries not Lorawan?Thanks.Selim.

Hello,NUCLEO-WB55 cannot connect to STM32CubeProgrammer. But STM32CubeProgrammer found ST-LINK. And I could upgrade ST-LINK Firmware. STM32CubeProgrammer indicated "10:44:57 : ST-LINK error (DEV_CONNECT_ERR)".Please check attachment image.Please let us know the case of this issue.Version information:STM32CubeProgrammer v2.5.0ST-Link firmware version: V2J37M26Best Regards,Tsutsumi

Hi, When I looked for procedure to update with OTA, I didn't find any code indicating address of software image source to FUS. SHCI_C2_FUS_FwUpgrade(0,0) (in app_entry.c) seems indicate 0 on source, and 0 on destination. So I'm wondering how the FUS find the source address of soft image to load during à OTA update.Thanks in advance !Matthieu

No idea on how to resolve this problem. If I compile and run without the board the message is error on init the sensor board. Any clues?

Hello everybody,my project is composed by a RX board and one/many TX boards (max 3). Every board uses CMWX1ZZABZ-078 module.The TX boards transmit asynchronously to the RX board a payload of 32 bytes (they are temperature IR sensors which communicate with the central unit(.After some hours of work I clearly see the RX Done IRQ pin (SX1276 DIO0) that goes HIGH to trigger the RX Callback on STM32L082 but it never goes back down, it's like the interrupt flag is never cleared. Could it be a problem of many interrupts occuring in the same moment?I've seen that the "workaround" for the problem is DeIniti and re-Init the IRQ Pins between SX1276 and STM32 but I really can't figure out what is that causes the problem.Thank you in advance for the support.Andrea

Hi,I am writing an external flash loader for the STM32WB55RGVx using a Macronix 64Mbit QSPI NOR Flash (MX25R6435F).I have had some success following the "MOOC - External QSPI loader how to" youtube video series by ST and the example code for memory mapped QSPI available in the "STM32Cube MCU Package" downloaded from ST website.Using the example code modified to my custom board I am able to erase, write, and read memory-mapped from the FLASH.However, when I use the created External loader (based on the example code and video series) I am able to read the FLASH using the STM32 CubeProgrammer, but the first 2 bytes are always 0 even when the flash has been erased only.I also found that the Errata sheet for STM32WB (ES0394) rev. 7 lists some issues with the Quad SPI and I am wondering if there are some additional issues with the QSPI and certain FLASH memories.Has anyone had success writing an external FLASH loader for the STM32WB or experiences with QSPI FLASH that may help me?Any help wi

Hi, I apologize in advance for my English (I'm French)I'm begginer with OTA. So I followed instruction from AN5247. All of the following procedure uses file from STM32Cube_FW_WB_V1.8.0 folder. I downloaded last FUS and BLE stack on my Nucleo board and my Dongle. I loaded the binary file of BLE_TransparentModeVCP on my Dongle, and loaded the binary file of BLE_p2pServer_ota on my board starting 0x08007000 (So this binary is already configured to enable OTA).After that, I have launched STM32CubeMonitor-RF, I have started communication with dongle thanks to the right port. I have selected OTA update from "device" menu. The searching for devices procedure works correctly and I find my board with the "OTA Enabled". The issue is following : I load image file path from my folder (HeartRate_OTA for exemple), and click on update, but after some seconds, it's print "No Response"...I don't understand why.Is someone have any idea ? Thanks in advance

HiI'm trying to generate a 64 kHz PWM with 50% dutycycle. I've configured the SYSCLK to use the HSE in combination with the PLL resulting in 64 MHz. Since I'm using TIM1, which is on APB2, I've configured the APB2 timer clock also to 64 MHz. However, if I configure TIM1 (no prescalers) to a period of 1000 and a PWM pulse of 500 the generated frequency is not 64 kHz but 32 kHz. Did I misunderstand something? Where is the additional division by 2 happening?ThanksRegardssecuresClock configuration:Cube generated code:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};   /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1); /** Initializes the CPU, AHB and APB busses clocks */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RC

Hey guys,I am new to stm32 microcontrollers.I am using CubeMX to generate my projects. I already accomplished to start a new project with the board STM32WB55 Nucleo and to program the timer / leds etc.However, if I try to build an example project from CubeMX, I am unable to build it. The error message saying "fatal error: no input files". I checked the path and location and the file is actually there.(see attachment). I have been searching the internet for hours to find a solution. I hope one of you guys can help.Kind regardsRené

I will use P-NUCLEO-LRWAN2.Lora device is a custom board by made me.I want to use P-NUCLEO-LRWAN2 gateway.so, I saw user manual. but the user manual explains just TTC and Loriot. I really want to function is Data come from Lora device send to pc server through the gateway. for example ubuntu Linux or anything.can you give me guide.

Hi! I have p-nucleo-wb55 board. I watch very strange behavior: all ok, when I load precompiled demo from st.com. But when I compile hex from example sources(ble_p2pserver application), board not working. Green LED lighten 1 minutes, but not blinked, and device is not discoverableI suspect that need upgrade ble stack. But firmware is not upgradeble.My steps:1. Load DFU_Standalone firmware over swd2. Install jumpers to BOOT0 pin and USB_MCU3. Plugin USB cable in user usb port4. And finaly try upgrade fus and ble stackLog:STM32_Programmer_CLI.exe -c port=usb1 -r32 0x20030030 4   -------------------------------------------------------------------   STM32CubeProgrammer v2.5.0   -------------------------------------------------------------------     USB speed : Full Speed (12MBit/s) Manuf.

The Bluetooth Core Specification states:> Slave latency allows a slave to use a reduced number of connection events.> The connSlaveLatency parameter defines the number of consecutive> connection events that the slave device is not required to listen for the master.While optimizing throughput in a Bluetooth Loader for SBSFU I observed:Connection Intervals too low won't let me delete flash contents (because timing protection in CPU2).Increasing the Connection Interval results in successful operation but of course slow down the overall transfer speed.As far as I understand the Bluetooth Specification, increasing the Slave Latency should allow for shorter Connection Intervals while giving the the controller opportunities to ignore one (or multiple for higher Slave Latency) Connection Event.From my benchmarks a connection interval value of 20 (25ms) in combination with a Slave Latency of 1 results in the same throughput as a Connection Interval of 40 (50ms) with Slave Latency 0.So

I have a B-L475EIOT01A2C evaluation board with SX1272 MBed Shield (SX1272MB2xAS).I'm trying to understand the samples in the en.i-cube_lrwan file structure which I downloaded from LoRaWAN software expansion for STM32Cube.When I load for example End_Node or PingPong into STM32CubeIDE, the only project in the file structure is mlm32l07x01. The Includes under C++/C General..Paths and Symbols reference folders at a higher level than the project. So it seems this project is a subset of something else. Is this project only for MAC sublayer management entity (MLME), or something else? But how can I run for example End_Node or PingPong under STM32CubeIDE, and where does the Lora code go when I create a new project under STM32CubeIDE for the B-L475EIOT01A2C evaluation board?
