STM32 MCUs Wireless

I'am using STM32WLE5JB with LOWPOWERMODE_STOP(0,1,2) to deacrease power consumption. Although I configured LPTIM with LSE for 2 sec period to wake up, device doesnt exit from stop mode. I tried LPTIM with LSI the result was same. Here is My code LPTIM Init:__HAL_RCC_LPTIM1_CLK_ENABLE(); __HAL_RCC_LPTIM1_CLK_SLEEP_ENABLE();   __HAL_RCC_LPTIM1_CONFIG(source);   LPTIM1->IER = 0; LPTIM1->IER |= LPTIM_IER_ARRMIE; //Autoreload match Interrupt Enable   LPTIM1->CR |= LPTIM_CR_ENABLE; // Enable LPTIM1   LPTIM1->ARR = autoReload; // set AutoReloadRegister 32768/65536 = 0.5 Hz   while(LPTIM1->ISR & LPTIM_ISR_ARROK != LPTIM_ISR_ARROK);   LPTIM1->ICR |= LPTIM_ICR_ARROKCF; // clear IRQ flags // Enable timer counting LPTIM1->CR |= LPTIM_CR_CNTSTRT; // Start LPTIMRCC initRCC->CR |= (uint32_t)0x00000100; RCC->CR &= ~RCC_CR_HSION; tmp = RCC->ICSCR; tmp &= ~RCC_CR_MSIRANGE; tmp |= RCC_CR_MSIRANGE_6; __HAL_RCC_MSI

Hello,One of our product is equiped with an early stage STM32WB55 version called 'cut 2.0'.I would like to update the copro wirless binary version to either stm32wb5x_BLE_Stack_full_fw or stm32wb5x_BLE_Stack_light_fw recent version like v1.8.0.Do you know if v1.8.0 is compatible with 'cut 2.0' and if not what is the most recent version I could update with?Thanks a lot.

Hi, Would anyone have advice or example of how to do Packet Filtering based on Preamble Start in the I Cube LRWan V1.3.1 package using the B-L072Z-LRWAN1 project. Thank YouRegards

HelloThis is my first time using the community. I don't understand how to use the communityLet me ask you a question.Currently, I am checking the reception of IEEE802.15.4 on the board of STM32WB55 Nucleo Pack using the sample Mac_802_15_4_FFD.Stm32wb5x_Mac_802_15_4_fw.bin Ver 1.8 is written to CPU2. 30ms TM_Delay () after the sequence in the main loopIs put in. Also, in APP_MAC_mcpsDataIndCb (), we only toggle the LED.In this state, when the transmitting side continuously transmits at intervals of about 500ms, it is received without problems even after about half a day, but when the transmitting side continuously transmits at intervals of 10 to 100ms, it is received after several hours. ButIt will stop. This phenomenon will occur no matter how many times you go.When I checked the details, the IRQ interrupt (IPCC_C1_RX_Handler) from CPU2 did not come in.If you know why the IRQ interrupt from CPU2 does not come in if the transmission interval is shortCan you tell me? Also, is there a wo

HelloWe are currently using sample Mac_802_15_4_FFD to verify IEEE 802.15.4 transmission on the STM32WB55 Nucleo Pack board. The protocol stack is stm32wb5x_Mac_802_15_4_fw.bin V1.90.I have sent data (MAC_MCPSDataReq) that requires ACK (ack_Tx = 0x01) from STM32WB55 to Dongle (manufactured by another company), but the status of APP_MAC_mcpsDataCnfCb () is 0xE9.When I monitor the packet using a sniffer, Dongle returns an ACK, but the STM32WB55 retransmits 3 packets. Why doesn't STM32WB55 recognize ACK? In addition, Dongle has received the transmitted packet without any problem.The communication distance is about 50 cm. The procedure for initializing the Protocol Stack is the same as the sample code, and the PAN ID is set to 1. In addition, Dst Address specifies the MAC address of Dongle.If you do the same for another company's MCU (protocol stack) in the same environment, the ACK will be recognized properly and the packet will not be retransmitted.Originally, the PAN ID communicates wit

Hello!I have created a new project based on the ST example BLE_HeartRateFreeRTOS. I made the comparisons between both projects and added what was missing in my project. I think that I have copied everything that I should but the advertising doesn't start. The program doesn't achieve the function APP_BLE_Init . It should propably be called by the task ShciUserEvtProcessId = osThreadNew(ShciUserEvtProcess, NULL, &ShciUserEvtProcess_attr); but it doesn't happen. When I pause the debugging the program goes to function vPortValidateInterruptPriority . Could someone help to solve this issue?

Hello,when generating the code by CubeIDE, the RTC cannot be used with LL drivers in user's application program. It must be used with HAL drivers, since the functions "HW_TS_Init" and others of file "hw_if.h" need "RTC_HandleTypeDef".These functions generated by CubeIDE should also use LL drivers.Best regardsPaul

For our senior design project, we're trying to pair our created phone app (android) with the STM32WB55. Unfortunately, the WB55 only bluetooth pairs with apps created by STMicroelectronics. How do we use our app to connect to the WB55 without having to use the ST bluetooth apps?

Hi all,I need a dual bank firmware update to meet some requirements. I have a STM32WB55 with 1MB of flash which is seperated in 3 sections of 300kb (ble, appliciation and an update stack) + bootloader. I can do a firmware update and now im trying to speed up the transmission process. Currently im sending the binary to the update stack. My ble service sends 4 bytes header with 16 bytes of data and directly safe the data on flash using HAL_FLASH_Program and a semaphore (required for bluetooth connection see ble_RfWithFlash). Because programming flash is pretty slow, 5.5 ms for double word, so > 11ms per message, it takes a long time to transfer the entire binary...What would be a good way to improve this timewise? I came up with a two solution but dont know what is the best approach and what the advantages and disadvantages would be.Create a buffer of one page and use fast program to program one entire page instead of 2 double-words each time(i do have enough free ram)Use data length

When creating an BLE router application with CubeIDE, CubeMX does not generate the IPCC IRQ handlers "IPCC_C1_TX_IRQHandler" and "IPCC_C1_RX_IRQHandler".Is there some "hidden" checkbox I missed or has it been forgotten in generation engine?

Hello,I am trying to use the STM32WB55 Nucleo Pack to develop a BLE application.Does anyone know what these constants represent ?/** * There is one handler per service enabled * Note: There is no handler for the Device Information Service * * This shall take into account all registered handlers * (from either the provided services or the custom services) */ #define BLE_CFG_SVC_MAX_NBR_CB 7   #define BLE_CFG_CLT_MAX_NBR_CB 1This code is extracted from the client project but it is the same in the server project.Thank you for your reply!

Hello,is there anyway to get an event or interrupt, after the transmission is finished of each packet from Advertising. I know this depends on Intervals Min and Max buti don't want to make a timer to syncronize an interrupt with the intervals. Thanks.

HelloLet me ask you about the Shared area of SRAM2a of STM32WB. The Shared area of SRAM2a defined in Nucleo\Applications\Mac_802_15_4\Mac_802_15_4_FFD project is 16KByte. Is it possible to reduce this area? Is there any problem with making it smaller? I searched a lot, but couldn't find an article about the capacity of the Shared area.The RF stack uses Stm32wb5x_Mac_802_15_4_fw.bin Ver 1.9.The final MCU to be used is STM32WB50CGU5, but since the capacity of SRAM1 alone is insufficient, I would like to use SRAM2a as much as possible.

Hi,Because is quite frustrating debug from smartphone, there is a cooked firmware to transform the usb dongle in usb adapter? This could allow me to debug the characteristics from linux. Of course before to ask I already discovered the entirely sdk without success. If nothing exists a common usb adapter bluethoot 4.0 is enough?Thanks

I have read AN5289 and it does touch on the subject but there is not enough detail in it to get to a working solution.From my code: /** * Initialize authentication */ BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.mitm_mode = CFG_MITM_PROTECTION; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.OOB_Data_Present = 0; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.encryptionKeySizeMin = 8; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.encryptionKeySizeMax = 16; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.Use_Fixed_Pin = 1; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.Fixed_Pin = 111111; BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.bonding_mode = 2; I would infer that a fixed pin is required and that fixed pin is 0x111111 but that is not the case.Thanks for any help.-Louis

Hello,I open this thread to tell you about one issue I've been having with my implementation of EN-I-CUBE_LRWAN code on a custom board using the STM32L052 MCU.I started with the End_Node example on the L053-Nucleo's folder, and made it work, with an interruption on the PA1 pin, in conjunction with the usual timer wakeup. However, a new version of the board changed this specific pin definition, making me switch the interrupt to the PB4 pin. This time, working behind a pull-up aswell. Changed Rising trigger to Falling and the pull configuration in the GPIO config. Disabled LowPower to debug the interrupt in isolation and it worked without issue.The problem came with I enabled LP again. It doesn't seem to enter the interrupt handler. I know of this because the board has a buzzer which should beep everytime it enters that Handler (Thing that happens when LP isn't enabled). What may be happening? As the previous interrupt worked and this one isn't, I'm kinda lost as in why this isn't workin

Hey everyone,I'm having trouble on my STM32WB55RG custom board.Using version 1.7 of the Cube FW package, my board worked properly. But one day, my device was not discoverable in Bluetooth (I suspected that I deleted it whith my custom bootloader, but I verified the code and don't see how that's possible :\ ).I looked into the copro binaries and everything seems fine...I tried programming the examples that I had, but it does not work: my phone does not find the STM32WB.I might have some old WB samples, as I had a problem with flash that was only related to the first samples (see here: https://community.st.com/s/question/0D50X0000AvfFNKSQ2/why-error-flashsr-is-set-and-block-erasing-flash-memory )I have 3 other cards from the same batch where the memory section where the FUS is supposed to be is readable. Those 3 cards have a very suspicious behavior that I suspect being related to it... They are currently being transported to meWith all of that I am a bit concerned that my board is simpl

Hi, I tried to follow the workshop to start developping with my P NUCLEO WB55.The only thing is that the used firmware is 1.0.0. or something close...I'm pretty sure the 1.7.0 is introducing new cube ide improvement... but i'm really having hard time making it works...It seems that the generated code is not fully working directly. I'm struggling trying to figure out what's missing or what's wrong with just a simple custom ble service.I think i found that (just like the old workshop), it is needed to start the sequencer in the main.c file and insert lines in the stm32wbxx_it.c file... But how are we supposed to figure this out by ourself ? Best regards,

I am using a STM32WB50CGU5, when erasing flash memory where my settings are stored, the BLE connection breaks. It happens even if I erase only one page (number 96).I think the two CPU conflicts doing flash operations, but the datasheet reports:"The embedded Flash memory is shared between CPU1 and CPU2 on a time sharing basis. A dedicated HW mechanism allows both CPUs to perform Write/Erase operations."What can I do to fix this problem? Is it a BLE stack problem?
