STM32 MCUs Wireless

Is there anything to change in the firmware "STM32CubeExpansion_LRWAN_V1.2.0"? If there, then where, what and how we need to change?I am using my laptop to configure using COM port for this device. So how can I get confirm that any data has been received as a downlink?I am able to send data to Loriot in class A, But not able to see any downlink data.Thank you.....

Hi,expert.I am a beginner who started using STM32WB.I am trying to download the wireless stack using STM32_ProgrammerCLI.exe and command prompt while reading UM2550.I understand that there are seven types of wireless stacks:・stm32wb5x_BLE_Stack_fw.bin・stm32wb5x_BLE_HCILayer_fw.bin・stm32wb5x_Thread_FTD_fw.bin・stm32wb5x_Thread_MTD_fw.bin・stm32wb5x_BLE_Thread_fw.bin・stm32wb5x_Mac_802_15_4_fw.bin・stm32wb5x_rfmonitor_phy802_15_4_fw.binFor example, if I want to do BLE, should I just download "stm32wb5x_BLE_Stack_fw.bin"?Or do I need to download all of these?Thank you for your attention.

Hi Sir/Madam,The Sensor Capacitor (Cx) is not connected in the below mentioned. Can you please provide clarity on the Cx connection with MCU.While configuring the shielding in TSC using STM32CubeMX, it is asking to configure Cs(Sampling Capacitor) in the same group. In the above mentioned figure, i didn't find. If it is need to be connected, please provide a reference. Its really helps me a lotIs RsShield connected in parallel to the all the touch keys?Please find the STM32CubeMx image regarding 1st point.

hello, Please be kind to me as I am new to this. I have a B-L072Z board.Use the End_Node program to communicate with the lora gateway, I found that the data transmission interval of the terminal is 10 seconds. I can reduce the time to 7 seconds by changing the value of "APP_TX_DUTYCYCLE". But I want to set the data transmission interval to less than 1 second,is that ok ? If so, how can I modify the End_Node program? Thank you very much!

Is this function related to UART communication ?What void " vcom_Init( void (*TxCb)(void) ) " do ?And what is the argument of this function ? thanks in advence

When I connect the two pads at the PCB, routing under the module, TCXO_VDD will have a voltage of 0.8, irrespective of whether PA12 is high or low. In fact, I have only found it by taking the cover of the module and find a capacitor pad where TXCO is connected. When set to high, the track voltage will spike for a few nanoseconds and then quiesce again to the 0.8 V level. I am trying to solve the situation by routing from outside the module, like we can find at the LRWAN1 development board. Will it be enough or is there some sort of a weird module quirk I have to consider? Thanks in advance.

Hi, I want to use i-cube lrwan stack for my hardware, I use stm32l151cb+sx1276. I have tried to use STM32L152RE-Nucleo and modify it. I did it for the microcontroller side and have modified pin and peripherals mapping. but I can't change radio expansion from sx1276mb1mas to sx1276mb1las. I want to have a US915 lorawan node. when I call join function, I don't see any radio signal transmitted from the radio. about the hardware I'm sure it's OK. because using other lorawan stack, it works fine.

Hi Sir/MadamIn MB1355 MCU supply domain schematics(above one) I didn't understand supply connections. If only 3V3 supply given which connections are not required in the schematics?

Hey,I'm trying to get a binary for the BLE OTA application, but if I compile the example BLE_Ota with SW4STM32 the binary is around 393.411 KB. STM32CubeWB 1.1.0 with Patch 1.1.1 was used.How can I get the same size and file type like the reference file? I can't find any other steps I need to do. Even the corresponding documents din't help.Kind regardsNyix

hello ! I just started develop with stm and my project which based on i-cube_lrwan/AT_Slave in i-cube_lrwan.zip.Today, however, the software is upgraded from 1.2.1 to 1.2.2.​So I'm trying to find patch notes or changes to see if I can upgrade, but I can not find where the documentation is posted.how i can get it?

The mesh library for the STM32WB55 only seems to be compiled for the IAR compiler as of right now, and there also seems to be an older version of the BlueNRG mesh library available for keil. These compilers are both very expensive and do not work under linux.Are there any plans to release a gcc version or even the source? As it is, the library is unusable for me, which is not great when the device is marketed as mesh compatible.

Hi Sir,Initially, we chose the STM32WB55 (QFN48) it has only one group. Currently we required a slider (linear). So we are moving to the QFN68 package. In my case, i need six plus keys, So Can I avoid the shielding to get the 9 keys? One Shielding I/O is enough to all the keys?Thanks You

Hi Sir/Madam,In STM32CubeMX, the TSC in System core, we finding only group-2 with four I/Os. I am thinking that there must be group-1, group-3, group-4. So that we can implement TSC with more keys. please suggest me proper settings required to do this.Thanks & Regards

Hi Sir/Madam,Here are developing a PCB with touch interface. We found the schematic files in st.com website. In that schematic, touch interface is not implemented. Can you please share the suitable link or any reference files to understand the TSC connections, So that it will be very much helpful to complete my project.Thank You,

I have a STM32CubeExpansion_LRWAN_V1.2.2 project in System Workbench. I opened/converted it with TrueStudio. I modified the code and successfully compiled and ran it.I followed the guide to Migration from TrueStudio to STM32CubeIDE and the conversion fails. The Original TrueStudio conversion appears to have left behind some System Workbench "AC6" artifacts in the .cproject and .project files. I edited these files and deleted these remanents but one of them still causes STM32CubeIDE to **** on the conversion.Aw nuts. Any ideas?

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
