STM32 MCUs Wireless

Hi, I am looking for compatible Zigbee full device stack for STM32WB. Is ST provide suck stack for ready to port and use on STM32WB.

Hi. I am trying to update my board using STM32WB Copro Wireless Binaries. But, I am getting following error: I cannot download the image. Can you please help me with this issue? I can flash the board but cannot use bluetooth functionality.

I am getting stuck at SVCCTL_UserEvtFlowStatus_t SVCCTL_App_Notification( void *pckt ) function inside app_ble.c. Is there any documentation which would tell how this part of the code is written?

Hello, we have developed a device based on SPBTLE-RF and stm32L452.To certify the device we have to operate BLE modules in direct mode. If I understand correctly DT0069, hci is only on SPI and we should forward on the UART. Are there any code examples for stm microcontrollers which forward hci interface on the UART?Many Thanks.

Hi, i hope you are all goodI use the node B-L072Z-LRWAN1 with the example “end node�? of the stack “STM32CubeExpansion_LRWAN�?, the objectif it’s to send data of sensor to TTN. and I managed to send “int�? or "floa"t without problem to my TTN as first step.on the other hand, I made a program of UART communication of the “B-L072Z-LRWAN1�? thanks to STM32CubeMX, and it’s working well.Unfortunately I don’t know how integrated all the code that STM32CubeMX generated in the “end node�? project to send my UART data.thanks in advence.

Hello,I have a B-L072Z-LRWAN1 module and use AT commands, but I do not know how to change the frequency I need 915Mhz, but when I use the command AT + TCONF =? It shows me the following:Freq = 868 MHzPower = 14 dBmBandwidth = 125 kHzSF = 12CR = 4/8LNA State = 0PA Boost State = 0868: 14: 125: 12: 4/8: 0: 0then I change the compilation options, but there are no changes when executing this command, that is, the frequency always shows it in 868Mhz

I am using stm32g071rb controller for door interlock system. Now I want to display the status of doors(open/closed) into computer through wireless (live monitoring). Will esp8266 Ethernet module work with stm32g071?

So I am trying to port the cube LRWAN example for the Semtech expansion shield SX1261 from the existing Nucleo L476 to a L412 variant. I do know that it should be possible because they are not very different (Probably it is easy to do but I am simply not experienced enough).What I did is the following :Changing the Defines to L412XXChanging the pin mapGenerating a SystemClock_Config using CubeMX -> Copy paste into the ProjectSPI is SPI2 instead of SPI1 so I changed thatSomething I did not understand: What is what is the trace file used for? I guess it's just used to plot to the console so I disabled the UART (Is this a problem? ) Sadly it's not working at all (No Signal on SPI Pins...). And I am completely out of ideas. So I need Help from a experienced ST User. If anyone has an Idea please let me know.Thanks in advance

Hey,are there any example projects for the STM32WB55 Nucleo Pack for STM32CubeIDE?best regards,Henrik

Hello,I am novice with STM devise. I received a B-L072Z-LRWAN1 Discovery kit with the goal to build a LoRaWAN gateway repeater (or relay). Thank to Clive, I could complete the fist step and here is the solution (see 3 last conversation).Now, I would like to manager the nodes in order to allow then to communication through the repeater (Discovery kit). Here are the steps and unfortunately it's not really cleat for me.First question (may be stupid) Node-red should it be install on my Macbook, or on the Discovery board? I got an advise, and here it what I did until now, on my Macbook Air.Reference 1 Reference 2$ cd /usr/local/ $ sudo mkdir nodejs $ cd nodejs/ $ sudo curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/" $ node -vThe last command return me v10.16.0Then

I have installed the recent version of CubeMX - 5.2.1.I have downloaded STM32CubeExpansion_LRWAN_V1.2.1.When I try to add it in the Embedded software package manager, I get a message: This package version is not managed in the version of STM32CubeMX.

Hello !I'm sending a LoRaWAN message tothe ping pong code wich plays the role of a gateway but the message is received encrypted , I need to decrpt it on the reception side.Any help please thank you!

Are there any documents that describe the use of the scheduler or the openThread API in more detail? A little more detailed explanations of using the openThread api and the Scheduler would be very useful.What are the advantages of using this Scheduler versus Freertos?Thank you!

The murata Lora module CMWX1ZZABZ is used and the STM32L072 is inside.Can the STM32 internally reset itself without using the reset function?Explain what happens if a reset occurs.

I am getting invalid values for the device id and package data from the STM32WB55 on a P-NUCLEO-WB55 Nucleo board.I am getting a value of 0x26 for the Device ID in the UID64 at 0x1FFF7584. And I am getting a value of 0x13 for the package type in the Package Data register at 0x1FFF7500.According to the STM32WB55xx reference manual (RM0434), the device id is supposed to be 0x25. Also, the value of 0x13 does not correspond to any package type.Which is the correct value? Is the error in the reference manual or on-chip?

Hi,I have some experience with BLE and Nordic devices (mostly nRF51822 and BLE 4.1).The Nordic provides sniffer firmware for their devices and I used it a lot. ---Now, thanks to ST team, I have the P-NUCLEO-WB55 kit in my hands and started playing with it. I am thinking about BLE 5 now.I wonder if ST has a sniffer software using the USB BLE dongle (the dongle is a part of the P-NUCLEO-WB55 kit).Thanks,Bogdan

Binary Install Address for STM32WB5xxE(512K) and STM32WB5xxC(256K) devices.Hi!In Release Note for STM32WB Copro Wireless Binaries writes what is install address for stm32wb5x_FUS_fw.bin depending on the chip model, as:STM32WB5xxC(256K) - 0x0803E000STM32WB5xxE(512K) - 0x0807E000STM32WB5xxG(1M) - 0x080EC000Is Ok, but for "stm32wb5x_BLE_Stack_fw.bin" one address specified:stm32wb5x_BLE_Stack_fw.bin - 0x080CC000This address is for 1M chip, but what is addresses for 256K and 512K chips ?If use address 0x080CC000 = 835584 bytes but in 256K and 512K chips no such amount of flash memory.Or am I not doing something?

HI,Does someone can explain me how to modify the ATT MTU size please ?Thanks.

Right now we have sensors that go into standby mode and are woken up by Alarm B every minute for testing purposes. However, at completely random occasions, the device is no longer woken up at the alarm times (so we are preventing for 24hr RTC overflow, etc).Tried checking the return values of the alarm functions for errors and all seem fine. We suspect the US915 LoRa stack might interfere somehow with the Alarm interrupt because we can't replicate this issue with the EU868 version of the stack.We have another external interrupt on a motion sensor and when we trigger it, the alarm is set again for 1 minute and everything works again as if nothing happened (framecounter and device variables are retained as it should be, so no fault has occured. It's just that the alarm IRQ did not fire correctly, we think). It will stop waking up after some time again...Does someone have a similar experience and might now how to fix it?
