STM32 MCUs Wireless

..

Hi,i am building the code for STM32WB55. I have enabled "Convert to binary file (-O binary)" and "Convert to Intel Hex file (-O hex)".I got 2 files:-bin file - 402MByte size-hex file - 183kByteAs i can see, bin file has 62kByte of real data and rest of data are "0x00". How i can make just normal BIN file? Please help to find out :)--Best regards,Sergii

I am currently working with the I-CUBE-LRWAN software expansion package with the B-L072Z MPU. I am trying to set up the device to allow multicasting, but I am confused on how to do so. The device is already set up as a Class C. Would I set up the McAppSKey and McNwkSKey solely on my Application or on both my Application and end device? If it is on both, how would I go about setting the McAppSKey and McNwkSkey on my end device?

I started using STM32wb55rgv6 nucleo board recently and I have been doing my early development in CubeIDE 1.0.2. [converted SW4STM32 project files].I've trying to replicate the OTA + BLE_p2pserver example and I hit the following snug:As part of the OTA procedure, one has to generate the .bin file for the application. CubeIDE consistently creates huge .bin files (~400Mb) from the BLE_p2pserver example as well as from other examples with BLE; it seems unrelated to OTA. The same step works just fine on IAR; I get the expected 32Kb binary file.As mentioned elsewhere, it's probably because of some high memory location included in the non-sparse binary, but I don't seem to be able to find a way around it. Enumerating all the sections in the linker file does not give a working app:arm-none-eabi-objcopy.exe -v --output-target=binary -j .isr_vector -j .text -j .rodata -j .ARM.extab -j .ARM -j .preinit_array -j .init_array -j .fini_array -j .data -j .bss -j .user_heap_stack BLE_p2pServer.elf "BL

As the data sheet states the stm32wb55 MCUs has RF wake up capability at Standby mode, I am looking for some examples and references that implements the use case of wireless wake up events. Thank you in advance.

I’ve modified the firmware code generated out of STM32CUBEMX the endpoint size change from 64B to 128B. Since this change is in the firmware, the Host driver will read this value from the Device descriptor (during enumeration) and ensures that the driver receives and transmits max of 128B. Though it is against the USB2.0 FS standards which recommend max of 64B, what could be the impact and issues. So far I've tested with short packets and upto 128B, it works seamlessly correct without packet or data loss.

does ST maintain an archive of CubeExpansions, e.g. I-CUBE-LRWAN? On the product pages, it is always only the latest version that can be downloaded.

Hi. I'm currently implementing an application for test purposes on the STM32WB Nucleo Demoboard. So far I'm very pleased with the experience of adding new services and transvering data. However, to save some energy I want to change the connection interval on my device to 1s or higher. I've enabled L2CAP_REQUEST_NEW_CONN_PARAM and called BLE_SVC_L2CAP_Conn_Update as in the p2p server demo application. That should start the connection interval change. However, in my case the application gets stuck in UTIL_SEQ_WaitEvt() in while((EvtSet & EvtWaited) == 0) with EvtSet = 0. The p2p server demo application doesn't. I can't find any differences regarding this function so far. If I understand correctly EvtSet is set by the M0 core handling the BLE stack. Is there anything else i need to set or change to enable the interval change of an established connection? thank you

Hello,I made several modifications to the STM32WB HandsOn_3 example (based on p2p-server project located at c:\STM32WB_workshop\HandsOns\HansdsOn_3) and succeeded to communicate with my mobile application - all OK =) However the above working solution is based on Sequencer (UTIL_SEQ_Run(~0) ) scheduling mechanism. As my entire project is based on freeRTOS, I'd like to find the best approach on how to convert the working Sequencer mechanism into freeRTOS Mechanism? (for P2P server project)P.S I tried to modified the above working HandsOn_3 project, in CubeMX 5.4 by unchecked the Sequencer utility, and checked the freeRTOS however:CubeMX auto code generator implements the HRS one way comm vs. P2P Server two way comm. while debug this code in CubeIDE (1.1.0) the FW got stuck in endless loop2. I checked the example located at:  ..\Repository\STM32Cube_FW_WB_V1.3.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_HeartRateFreeRTOSThis example works OK, however:It is again one wa

I am using the ST32CubeIDE and the imported HeartRate project from the STM32CubeWB package. For both boards the project compiles and is loaded into the board, and then the boards just stop working during debugging. I am not probing the boards or touching them in any way. This is the oddest thing I've ever seen. Has anyone else experienced this?

I couldn't get the CLI application running on the P-NUCLEO-WB55.USBDongle. I updated the FUS firmware according to ../STM32WB_Copro_Wireless_Binaries/Release_Notes.html and installed the stm32wb5x_Thread_FTD_fw.bin on CPU2. The FUS update exited with:FUS status is FUS_IMAGE_NOT_AUTHENTICError: Firmware not authentic!but STM32_Programmer_CLI.exe -c port=usb1 -r32 0x20030030 1 does return the right code (01000200). Flashing the stm32wb5x_Thread_FTD_fw.bin was successful. However, when I flash the ..\STM32Cube_FW_WB_V1.3.0\Projects\P-NUCLEO-WB55.USBDongle\Applications\Thread\Thread_Cli_Cmd\Binary\Thread_Cli_Cmd_reference.hex binary, the system doesn't seem to work. Windows is not able to detect the USB device. Error 43 (Device descriptor request error). The same procedure on the Nucleo64 (with the correspondig binary) worked fine and the CLI is available trough the ST-Link VCP.

I 've built a Lora sender with Arduino.I want to rebuilt it with STM32 (STM32F030F4P6).So I 'm thinking of starting with the Lora library https://github.com/sandeepmistry/arduino-LoRa .I mean to convert it to Atollic studio code (a class I suppose).(I 've also found an STM32 STM32duino library https://github.com/armtronix/arduino-LoRa-STM32/blob/master/src/LoRa_STM32.cpp that might help.Am I on the right track in accomplishing my goal?How do I create a class in TrueStudio?I just create a new file in src folder of my project?Right click on Src folder->New->Class?

I started messing around with the End_Node example with my B-L072Z-LRWAN1 board, and enabled the sensors despite not having the nucleo board to test with. Curiously I noticed instead of delivering an error, it just locked up.After some investigation I realised that it was hanging in an infinite loop, waiting for an I2C timeout that never comes. The timeout counter seems to be determined by the HAL_GetTick() function, which in turn has its variable incremented by the SysTick_Handler.Having placed a breakpoint on this function I can see that it never fires, leaving anything that relies on it for a timeout stuck indefinitely.I set up a quick empty project in CubeMX and it seems to be called absolutely fine. Changing the TICK_INT_PRIORITY in the example doesn't seem to do anything to fix it either.So why is the SysTick_Handler not being called? How do I fix this?I'm running the End_Node example from STM32CubeExpansion_LRWAN_V1.3.0 in keil uVision 5.

In addition to turning the Blue Led on with the p2p server app, I want to turn a Led on connected to a GPIO, using the same signal.

HiI don't not know if this is the right section to ask my question, but I did not found any specific topic for device S2-LP.I'm performing some tests with the above component interfaced with a MCU STM32L0. The communication is realized through a SPI interface. I succeed in sending a command but unfortunately I cannot understand properly the answer.In the S2-LP user manual, there is a list of registers that can be sued but not a description of transport ptotocol format.For example: The first character of the TX frame is WRITE_HEADER = 0x0. Is correct? The RX frame has another header character. These defines are into the S2LP library that I use. My question is: Is there a documentation that explaining which is the protocol used to communicate to S2-LP component? I read the official s2-lp.pdf user manual but I don't find this specific topic.Thanks in advance for the cooperationAdriano

I have the development board, B-L072-LRWAN1 with the CMWX1ZZABZ-078 module by Murtata on it. This module has an 32.768KHZ crystal on it which will be used for keep the RTC. I would like to implement a wakeup timer using this crystal to wakeup every 250MS to perform a check action, then put it back into stop mode, repeat. I would like advice on how this can be performed and what is required since I cannot find any code examples implementing this wakeup timer with the RTC crystal. I am using the Keil IDE to work with module, but have gotten the debugger to work with STM32CubeIDE. Any help would be appreciated. Thanks!

I'm working to complete the port of BlueNRG code to the STM32WB. I've gotten everything working up to the point where I make the device discoverable. The WB stack is returning an error, but there's no documentation to explain what this error could mean.Here's the binary exchange: # GAP discov   00000000: 00 00 00 00 00 00 00 00 01 83 fc 0d 00 00 00 00 ........ ........ 00000010: 00 00 00 00 00 ff ff ff ff ........ . #? complete 1 fc83 -> 42 ERR 00000000: 04 0e 04 01 83 fc 42 00 ......B. The first 25 bytes are the command sent to the stack. There are eight bytes of pointers that aren't used, one byte for the message type which is BLE CMD, the two byte command code, one byte payload length, and then the parameters. I'm using all default parameters at this point in order to eliminate possible issues. The response I get is code 42, which means parameter error. So, if the parameters are all defaults what could the parameter error be? I suppose I must be m
