STM32 MCUs Wireless

I'm trying to use Zephyr for development on the nucleo_wb55rg board. While doing this I noticed the problem described in:https://github.com/zephyrproject-rtos/zephyr/issues/27348I think that the sequence firmware flash writes matters. Writing stm32wb5x_FUS_fw.bin and then stm32wb5x_BLE_Stack_full_fw.bin works. But not the other way around. Could someone tell me why the order of writes is important?

Hellothe code generated by STM32CubeIDE version 1.4 with FW package STM32WB 1.8 for BLE application "Router profile" and "Router mode enabled" does not work: It cannot be scanned and connected by smartphone application.The reason (to my opinion after some investigation) is that the default clock configuration when creating new project does not work. I changed it as in distributed sample code to:RTC/LCD Source Mux -> LSERFWKP Clock Mux -> LSESMPS Clock Mux -> HSEWith these changes, the device can be connected.In addition, there are many differences of distributed sample code "BLE_p2pRouteur" (french word ;) which also does not contain the sub directory with binary reference as other sample projects.STMicroelectronics should change the code generator, so that the code work "just in time".Also there should be no difference (e.g.: detected by meld, diff or other tools) between generated and distributed code.Best regardsPaul

As far as I see, the wireless stack can be installed at any location.Currently the Release Notes for the Coprocessor Binaries give an address to install them to, depending on the part flash memory size.For example the BLE_Stack_light install location changed from version 1.6.0 to 1.8.0When updating the wireless stack in the product (i.e. without deleting the old stack) and the new stack is larger than the previous one, AN5185 states: If new image size > current image size: WirelessStackAddress - (2xImageSize – WirelessStackSizeIs the additional storage used temporarily? Or is the new stack installed below the current one?In the latter case: would it be sensible to initially install the stack at a lower address to allow updates "in place" when the wireless stack size changes?

Hello.I am involved in the F/W development of STM32WB55/STM32WB50. Since the load on CPU1 is likely to be high for the F/W of CPU1 (M4), we are thinking of reducing the load on CPU1 by performing operations related to wireless communication with CPU2 (M0 +).I searched for tools for F/W development of CPU2, IEEE802.15.4 protocol stack library, and sample code, but could not find them. Is it possible to develop an F/W for CPU2?

Hello,In STM32WB exemple BLE_HeartRate, i can see the name of HeartRate service on my phone (like image). But when i create my own service, how can i set a name for it ?Thank you.

Thre is an example “Thread_Coap_Generic that works very well. However, I’d like to increase Tx Power to improve de distance communication between the boards.I saw in the Middleware folder, there is a radio.c file. In this file, talk about configure Tx power.Is there anyone has set up or made it work?

Hi,I have created in the past several custom bootloaders with KEIL and IAR for STM32F2,F4 and F7I am now working on the WB55 with Atollic 9.3 I have a boot loader skeleton, a running application each running as stand alone without issues.I have set the VTOR register and updated the linker files.I have triad to follow the Atollic document "Working with bootloaders on Cortex-M devices" but so far with no sucess.When the bootloader does the jump the application is not running ..Is there any other document or example for the WB55 ??Thanks,Noam.

I use the Board  B-L072Z-LRWAN1 and i made o new project with Target  "B-L072Z-LRWAN1". How can i now use (import) the LoRaWAN-Examle in the St32CubeExpansion_LRWAN_V1.3.1?Greetings E_T

Hello, I need some help with getting the CFG_FAST_CONN_ADV_INTERVAL_MIN and CFG_FAST_CONN_ADV_INTERVAL_MAX in app_conf.hI am using Custom Template with Non connectable and no scan response.I have tried to call ret = aci_gap_set_discoverable( ADV_TYPE, My_Advertising_Interval_Min, My_Advertising_Interval_Max, BLE_ADDR_TYPE, ADV_FILTER, 0, 0, 0, 0, 0, 0);inside the app_ble.c and the function is called with return value of F and the Intervals are not updated.Can someone help me please with this problem and Thanks in advanced.

I am using STM32WB55 Nucleo Pack (STM32WB55RGV6 MCU) and STM32Cube_FW_WB_V1.3.0 SDK, I uploaded BLE_MeshLightingDemo code (without any edit) and provisioned the node using ST BLE Mesh app , all the elements in a node shows simillar models.I want to to run different models on different elements in a single node, help me please....

I am wanting to use stm32L476rg - a nucleo decelopment board that does not include SPSGRF. I am working on learning to communicate via SPSGRF from the nucleo to the STM32 IOT discovery kit - which includes SPSGRF integrated.Please comment on what files or code you would look at to integrate this library. The readme in the P2P_demo folder only tells me that it is easy to do - and it probably is. I'm using Keil in case that matters.Thank you in advance for your time.Frankhttps://www.st.com/en/ecosystems/x-nucleo-ids01a4.html#tools-software

I need to remote update the wireless stack. I read in the AN5270, AN5247 that this can be done only by FUS. I am already able to write in an opportune unprotected Flash location the new wireless stack, but i have not found how to communicate to the FUS FW where it is written and what to do, before launch it with the function SHCI_C2_FUS_GetState. I am looking at the application BLE_Ota contained in the firmware package 1.8. I have understood how the FW is passed via BLE between the 2 devices, but i have not understood how to set registers or flash part to tell the FUS where to write what.NB: my client is another STM32WB, not an Android Application or STM32CubeMonitorRF, so i can't use the BLE_Ota application as it is.Thank you in advance!

I am working with BL072z LoRa discovery kit which has ATSlave LoraWAN stack V1.1.0 flashed on it.AT commands are send over LPUART from host controllerGateway is used to connect to TheThingsNetworkI am using AT+JOIN command to join the network and send data and go to sleep on host controller.The power to discovery kit is always ONAfter, I wakeup from sleep I re-configure the LPUART and send AT+NJS=? to check if network is still joined.This returns status 0 meaning no network joined. Then I again send AT+JOIN and check network status using AT+NJS=? which shows it a success.I am not able to understand as to why do I have to send the join request again after wake-up?TheThingsNetwork shows that device is always connected.

Hello,i need to run a general purpose timer on STM32WB55, the Problem is when i enable the BLE in CubeMX the timer doesn't work anymore, even with or without an interrupt.Can someone help me please. Thanks.

When trying to refresh IWDG when it has not been initialized, causes the FLASH->SR->CFGBSY bit to get stuck on SET. It will not return to zero ever.Also mentioned in this post: https://community.st.com/s/question/0D50X0000Bh5LOVSQ2/trouble-programming-flash-with-halflashprogram by JHuan.1I couldn't find anything in the reference manual, nor in the errata sheet of the STM32WB55 cpu. Is there a link between IWDG and FLASH that I'm not aware of? Or how could IWDG have any effect on FLASH?

Hello,each time I open the ioc file of a STM32WB project, the clock configuration is reported to have an error in SMPS Clock Max (HSI is selected). When I click "Resolve Clock Issues", HSE will be selected. When I save, close and reopen the ioc file, the "correction" is lost and the same error is reported.I presume that this is an error in CubeIDE, which does not save the change...Best regardsPaul

Hi:My platform: STM32WB55CE.I'm using internal clock.I have rigged the TIM2 with an interrupt function. The interrupt could fire, but it will be fired right after all the initialization were done. More over, no matter how I change the prescaler value or the period value for TIM2's init struct, the interrupt seems always fire at the same short, <1second interval. I don't know where to begin, this is quite strange! Did I configured the wrong clock source? I heard that if you designated the wrong clock source the timer shouldn't work at all. Please help!

In my code i try to delete a flash mem page using if(HAL_FLASHEx_Erase(&FlashErase,&PageError) != HAL_OK)but always got an HAL_ERROR because in this function (which is called in HAL_FLASHEx_Erase...)HAL_StatusTypeDef FLASH_WaitForLastOperation(uint32_t Timeout) { uint32_t error; uint32_t tickstart = HAL_GetTick();   /* Wait for the FLASH operation to complete by polling on BUSY flag to be reset. Even if the FLASH operation fails, the BUSY flag will be reset and an error flag will be set */ while (__HAL_FLASH_GET_FLAG(FLASH_FLAG_BSY)) { if ((HAL_GetTick() - tickstart) >= Timeout) { return HAL_TIMEOUT; } }   /* check flash errors. Only ECC correction can be checeked here as ECCD generates NMI */ error = FLASH->SR;   /* Check FLASH End of Operation flag */ if ((error & FLASH_FLAG_EOP) != 0U) { /* Clear FLASH End of Operation pending bit */ __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_EOP); }   /* Now update error variable to only error val

Hello,When generating code from ioc editor with "STM32_WPAN": "BLE" and "BLE Application Type": "Router profile", but "Rounter Mode": "Disabled", the app_conf.h file is generated with error in line 303: enum not completed: /**< Add in that list all tasks that may send a ACI/HCI command */typedef enum{/**< Add in that list all tasks that never send a ACI/HCI command */typedef enum{BRPaul

I have CubeMX installed and when selecting SMT32WL family I get three BGA devices to select, but when I want to start a project based on these,I get the error: "STM32CubeMX cannot load this Mcu"I have CubeMX 6.0.1 and all packages installed.I would also prefer to have the QFN package in the tool, because that is the device I want to use on my boards.

Hi, ST team!My customer uses STM32WB55 in their development and recently he faced with following issue.When the WB into the standby - OK. After out from standby mode all peripherals need repetitive initialization (processes, clocks, memory etc.), but CPU2 is already in work mode (C2DS=0 and CRPF=1) and doesn't completely communicate with CPU1 (into the interrupt IPCC_C1_RX_IRQHandler doesn't in).We have been found the solution of this issue on ST community. There is a soft reset as I mentioned.Could you please to advice how to avoid soft reset?Thanks in advance!

..

can anyone guide me to how can we do this?

Hi all,Could someone help me to clarify about the power consumption of STM32WB55CG, I can't see the difference between 2 series STM32WB55Cx and STM32WB55Rx related to "Low power modes". But in my case, I can put STM32WB55Rx (In Nucleo board) to Stop 2 mode with only 2.5uA consumption but it cost 60uA with the STM32WB55Cx once (USB dongle). Here is the code I extracted from the ST ExampleLL_C2_PWR_SetPowerMode(LL_PWR_MODE_SHUTDOWN); /* Configure all GPIO port pins in Analog Input mode (floating input trigger OFF) */ /* Note: Debug using ST-Link is not possible during the execution of this */ /* example because communication between ST-link and the device */ /* under test is done through UART. All GPIO pins are disabled (set */ /* to analog input mode) including UART I/O pins. */ GPIO_InitTypeDef GPIO_InitStructure; GPIO_InitStructure.Pin = GPIO_PIN_All; GPIO_InitStructure.Mode = GPIO_MODE_ANALOG; GPIO_InitStructure.Pull = GPIO_NOPULL;   HAL_GPIO_Init(GPIOA, &GPIO_In
