STM32 MCUs Wireless

Hiat_master software works fine but end_node software not working I tried OTAA and ABP.

I have a project using the STM32_WB55 where I use CubeMX to setup a custom BLE template, services, characteristics, etc. I noticed that STM32Cube_FW_WB_V1.8.0 supports both BLE and FREERTOS, but when I enable FREERTOS, all my custom BLE settings are deleted. Additionally, many of the configuration tabs appear to be missing. I see there is an option to setup the heart rate sensor, but adapting this to match my initial custom BLE configuration seems to be a lot of effort compared to generating a custom template. Is there a way to use my custom template with FREERTOS in CubeMX? If not, is this something that will be supported in a future version?

STM32WB SoCs have radio module. I need a way to write own wireless stack but the documentation is lacking their description.So far documentation mentions 3 peripheral devices on APB3:0x6000 1000 - 0x6000 1FFF 4 KB 802.15.4 CTRL0x6000 0400 - 0x6000 07FF 1 KB Radio CTRL0x6000 0000 - 0x6000 03FF 1 KB BLE CTRLAnd 8 interrupts:BLE_BLUE_IT BLE blue controller interruptBLE_RFC_IT BLE radio control interruptBLE_RFFMS_IT BLE radio states interruptBLE_HOST_WKUP BLE host wakeup interrupt802_IT0 802.15.4 interrupt 0802_IT1 802.15.4 interrupt 1802_IT2 802.15.4 interrupt 2802_HOST_WKUP 802.15.4 host wakeup interruptThis would be great to get more information on what registers there are and how these peripherals function.Can anyone help me with that?

What could be a solution for this? Device would be a WiFi+BLE gateway, which runs Linux, and can support advertising scan for at least 300 beacons, and have Ethernet port.Something from ST?

I have followed the workshop on https://www.youtube.com/watch?v=V_qVURNbWuM&list=PLnMKNibPkDnHCD2Xc_xX-nWR7AoWBPK2Q. And the first time I went through it everything worked fine. However, when I tried it a second time it did not:I loaded the BLE_Ota_x.bin to the board using the programmer. I then use the ST BLE Sensor app to upload BLE_p2pServer_ota_x.bin into the board and set the memory allocation to 0xC000. This upload works well, but then if I want to load a new code through the app, e.g. the BLE_HeartRate_ota_x.bin, it does not work. The file does not appear as selected firmware, after tapping the SELECT FILE button and selecting the file. If instead, I tap the round button with the refresh arrow, I get a message saying "No node was found".I tried using the dongle in transparent mode as well and get an error or no response message after trying to upload the code.Thanks in advance.Cheers,Derek

Hi,I'm using CubeMX to generate the code for the STM32WB and I found a problem in the secuencer library which is automatically generated.When I register a new task in the scheduler, this places the callback function in TaskCb[0] but when I set the task to be exectued the scheduler tries to trigger it from TaskCb[1] and this leads into a HardFault error. I don't know if the problem is registering the tasks or exectuting them. Anyone else have seen this? Any ideas?Working with the vesrion: STM32Cube FW_WB V1.4.0.Regards,Diego

In P-NUCLEO-WB55 schematics, the pins are connected as shown below. I was not able to find much info from datasheet other than that its related to RF functionality. Can i leave it open if i am making a custom board with STM32WB55 controllers?

Hi there, I'm using a customized board based on B-L072Z-LRWAN1. I also use I-CUBE-LRWAN (v1.1.4), compiled on Keil uVision. Everything works fine. I can get about 2uA in Stop mode. Now I'm doing a project requiring power consumption optimized so I enable Sleep-On-Exit feature. At first, the process of initialization -> sleep (3s) -> uplink first time (enable an interrupt here) -> sleep is fine. However, after the interrupt executed, I can see it isn't back to main function but the current consumption is about 3.5mA. I figured out somehow the uC cleared the SLEEPDEEP bit in SCR register. So inside the interrupt I've set it again. And it did partially works. The current consumption is down to less 900uA but not what I want which is about 2uA or so.So far I've followed instructions in both programming manual PM0223 and reference manual RM0376 but no luck. Do you guys have any suggestion?Thanks in advance.

Does the STM32WB BLE stack support diversity antenna through an external RF switch?

What are the dimensions of package WLCSP59?

I am trying to initiate a project via cubeMx for the STM32WB55 nucleo board.I an able to initiate a simple project without the BLE middleware (STM32_WPAN).Once adding the STM32_WPAN, the generated project not compiled on both Atollic true studio and system work bench.Here is a link to a video demonstrating the issue.I am using: -CubeMX version 5.5.0 -Atollic true studio version 9.3.0 -WB package: STM32Cube_FW_WB_V1.4.0Thanks

Hello ST Team, I would like to use the STM32WL in a project that ends at the end of the year.When can I expect the STM32CubeWL MCU package to be released (Q4 was mentioned in a post -> Too rough)?Would it be possible to get a preliminary (also untested) version for testing purpose?Would it be possible to get a blinking_led STMCubeIDE project for developement?Thank you very much in advance.

Dear ST,   the current version of the CMSIS OS2 wrapper (V1.8.0 for STM32WB) does not support calling the functions osTimerStart() and osTimerStop() from an ISR. However, FreeRTOS does provided the functions xTimerChangePeriodFromISR(), xTimerStopFromISR() that can be called from an ISR as an alternative to the functions xTimerChangePeriod(), xTimerStop() used in the wrapper.   Could you please support calling the mentioned functions from an ISR in a future release?   Best regards, Roman

For an R&D project we are curently designing a PCB around an stm32WB , we use the stm32W55 usb dongle as reference design for our project.But we are currently not able to source some specific components : L3 : Ferrite FCM1608KF-601T0FLT1 : band pass filter LFB182G45CGFD436 So i would like to know if ST have other substitute with the same footprints ?Best regards,Pierre

Hello,I'm using CubeMx to create a project with usb cdc serial port and BLE functionality. CubeMx generates a sequencer UTIL_SEQ_Run(~0); that runs the BLE state machine. In the code below, if I comment out UTIL_SEQ_Run(~0); the code runs fine per Workshop #3 on Youtube. Prints out the data "Hello World" to hyperterminal. As soon as I uncomment UTIL_SEQ_Run(~0); and run the app in the debugger I get a hard fault. Has anyone seen this behavior while trying to run the sequencer with usb cdc? Any thoughts as to how to debug this as far as where I should start looking?Thanks,

Hello,I have the Nucelo-WB55 and my own board with STM32WB55CG.I've developed a BLE software on the Nucleo-WB55 and it works fine.When I uploaded the software to my own board it seems to have some problems.I configured all clocks, GPIOs and etc. (Believe I did it write).I see the BLE device (my own board) on the list of BLEs device, but when I want to connect to the device, the device unable to connect.When I work with Nucleo-WB55, it works fine and I can connect and see all device services.I working with IAR IDE, and useing BLE scanner App to get the BLE devices.What am I missing? what is the different between the MCUs and what configuration I missed??Thanks,Lior Malik

Hello,We have a made two PCBs with STM32WB55CGU6 Microcontroller in which the sole programming mode is by flashing the program into the Microcontroller by DFU Mode via STM32Cube Programmer.For the first PCB, we erased all the selected sectors in the PCB and after that, we were unable to recognize the USB device in DFU mode anymore and now we have unknown USB devce with code 43 where it is unable to detect the current device. The error is as shown below.For the second PCB, we wanted to test out the Bluetooth module where we found that the firmware for the Bluetooth is not up to date and thus, we flahsed the stm32wb5x_FUS_ fw.bin and stm32wb5x_BLE_Stack_full_fw.bin found in the STM file in Github https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x. We then flashed our program into the Microcontroller at the address 0x80000 then after a while we were unable to detect the USB and obtain the first error above. Performing a simple

Hi, I am developing a wearable device which obtain data from set of sensors, perform digital signal processing and upload to server or share data via BLE. Please suggest me a MCU series which has following feature,Wireless support DSP support Dual core - if possible Low power I found that ESP32 meet my requirements, but I would like to see options available with STM32 as they have good support etc.Thank you, Dilshan N.

Hi Team ST,We are using STM32WB55 series MCU for our project.RTC time not persist after resetting device. So for that we have comment out below three lines from SystemClock_Config() function. //LL_PWR_EnableBkUpAccess(); // LL_RCC_ForceBackupDomainReset(); //LL_RCC_ReleaseBackupDomainReset();After doing this now if we reset/reboot the device then device is not power up.Is this change impact to device power up stage?If we uncomment this part then, after resetting board again device is power on and works normally.So if this change is mandatory then how we can persist RTC time and date?Let me know if anything required from my side.

I've been trying to get this to work for weeks now.The board is functioning fine when I try the examples e.g. BLE-HID, but when I build a new application based on the code generated from CubeMX I can't connect to the board over BLE.The advertising is semi-working, as I can see the board, but I can't see the services nor do a pairing with the device.I have added the IPCC and RTC interrupt handlers, but the problem seems to be with initialization.The HW_IPCC_Rx_Handler is being tripped constantly. When compairing to the functionality of the BLE-HID example, once the initial setup is done, this handler is only tripped once an acutal connection is attempted.To me this indicates that these events are not being handled correctly, but I'm not able to determine what I am missing.Any help would be greatly appreciated.

Baseline:I can install FUS and Wireless Stack binaries via SWD just fine. I can re-install the wireless stack without a problem when no auth key is programmed.My problem:As soon as I install an auth key, installing/updating the wireless stack results in anError: -- Reserved --I recon this is because the FUS now also checks wireless stack binaries against the user auth key. In this situation I would expect the error to be: FUS_STATE_IMG_NOT_AUTHENTICI tried signing the wireless stack binary with my auth key (using the prepareimage tool). But I'm quite sure I did something wrong, because when I install that signed binary I actually receive the FUS_STATE_IMG_NOT_AUTHENTIC error.So the second question is:How to sign an STM binary with a user auth key? AN5185 states in Chapter 4: "The instruction to sign a binary with user authentication key are provided in STM32CubeProgrammer user manual." But I only see the commands to write they key via the bootloader.
