STM32 MCUs Wireless

In Group 1 G1_IO4 is a sampling capacitor and G1_IO3 is a sheild and in Group 2 G2_IO2 is sampling capacitor and G2_IO1 is input touch key. In Group 3 G3_IO4 is a sampling capacitor and G3_IO2 is a input touch key. so when i programmed with this configuration it detect touch from the shield not from the touch keys.My touch key code is this if(MyTKeys[0].p_Data->StateId == TSL_STATEID_DEB_RELEASE_DETECT) { HAL_GPIO_WritePin(LED2_GPIO_Port,LED2_Pin,RESET); HAL_GPIO_WritePin(LED1_GPIO_Port,LED1_Pin,SET); } if(MyTKeysB[1].p_Data->StateId == TSL_STATEID_DEB_RELEASE_DETECT) {HAL_GPIO_WritePin(LED2_GPIO_Port,LED2_Pin,SET); HAL_GPIO_WritePin(LED1_GPIO_Port,LED1_Pin,RESET); }Please give me the solution why the touch detect from shield not form Touch keys.

How should a user key be provisioned when only SWD access is possible?I see that while flashing the wireless firmware, Stm32CubeProgrammer first flashes a FUS_Operator binary. Can this FUS_Operator somehow be used to program a user key into the STM32WB?

To access AT command i have USB to UART FTDI adaptor from sparkfun.do i need to put firm ware inside chip for AT command for Lora?do i need to connect crystal osc of 8Mhz to work with AT command.No AT response from module in COM PORT Arduino!

In my STM32CubeIDE version 1.3.1 Build: 6291_20200406_0752 (UTC), the IDE automatically added the "--specs=nano.specs" for the GCC assembler.​However, the GCC assembler doesn't recognized the "--specs=nano.specs" option.I want to remove or disable the "--specs=nano.specs" for the GCC assembler as.My STM32 mcu is ARM cortex-m4 STM32WB55.My EVB is STM32WB55 Nucleo Pack.The GCC assembler version is  GNU assembler version 2.30.0 (arm-none-eabi) using BFD version (GNU Tools for STM32 7-2018-q2-update.20190328-1800) 2.30.0.20180329The build error message is as following.make all arm-none-eabi-as -mcpu=cortex-m4 -mthumb -g -c --specs=nano.specs -mfloat-abi=soft -mthumb -o "MDK-ARM/startup_stm32wb55xx_cm4.o" "../MDK-ARM/startup_stm32wb55xx_cm4.s"arm-none-eabi-as: unrecognized option `--specs=nano.specs'make: *** [MDK-ARM/subdir.mk:15: MDK-ARM/startup_stm32wb55xx_cm4.o] Err

Say the LoRa device is out of coverage of gateways. Has anyone seen libraries that would allow storage until coverage is regained?

Dear All,We have been working on STM32WB-NUCLEO Board from few days and started with the P2P Server example. We went ahead and tried to implement the P2P Server using only the Custom Template provided in STM Cube IDE (CubeMX). We are facing following issues with it for which we would like to have some guidance to find where the issue might be (The code has been attached for reference)STM32CubeIDE Version 1.3.0STM32WB CubeMX Version 1.7.01.      In the generated code, file custom_stm.c (line number 254 and 265) a bug was found where in the function aci_gatt_update_char_value the first parameter should be service handle but the generated code had passed characteristic handle. In the attached code this has been corrected. Before this correction notification on button press wasn’t working and this correction resolved that issue. I am a bit concerned why a released software has such

Hello! I am trying to save the data that I receive through bluetooth in the 1M flash memory of the Nucleo board(STM32WB55). But when I call HAL_FLASH_Unlock() the program goes to HardFault_Handler function and stands in the while(1). Besides that there are many addresses that have question marks"??" what decreases the available memory for me. The start address to save to is 0x0800A000. Any idea how to make my board save properly?

Hello,We are a group of students of Polytech Nice in a project using the STEVAL-STRKT01 LoRa tracker for GPS detection in the mountains. We know that this tracker is able to detect the accelerometer and we would like to use it with interruptions if the values change drastically in a short time. That being said, we are having troubles with this board and we'd hope anyone could help us.This LoRa tracker is supposed to be able to send information across many kilometers (could you confirm this please?), but last week we weren't able to send the buffer for over one kilometer. This may be because of the weight of the buffer of the topology of the terrain, as we were in the mountains between 800 and 1200 meters high, and there were many trees between the transmitter and the receiver. So do you know if this board is sensible to the topology or by things in between ?The code for the tracker was given to us and we haven't found a way to change the fre

I am using the STM32WB55 Nucleo board and the firmware pack (currently at 1.7.0) includes examples for the standard set of IDEs (EWARM,MDK-ARM & SW4STM32). I can import the SW4 project into the STM32CubeIDE, but it does not retain the link to the CubeMX file (which is in the root folder of the project). Is there any intention to update these firmware packs to the include ST's "preferred" compiler? It seems this should be the priority if they would like to get people to use it!

I have made my own board using the STM32WB55CGU processor (the 48 pin package, as used on the Nucleo Dongle, MB1293C.I am now trying to get the BLE working and tuned. The first step, it seems, is to load the transparent mode firmware into the chip which passes the USART TX & RX through to the BLE stack. It seems the firmware in the title should do this, but it is currently using the VCP, and I don't have the USB broken out on my board, so I can't use this. I do, however, have the USART coming out.Is there a simple way of switching this over to the USART in the sample code? I am using the STM32CubeIDE, and have imported the project, but it does not include the CubeMX file.

Hello - My project is based on the SensorDemoBLESensor application built using using the CubeMX tool version 5.6.1 with the X-NUCLEO-BNRG2A1 development board attached to a NUCLEO-F303RE. I successfully added 5 custom characteristics to my first custom service. When I attempt to add a 6th characteristic the aci_gatt_add_char() returned 0x48 (BLE_STATUS_OUT_OF_MEMORY) on the STM32F303. I added a 2nd custom service and successfully added the characteristic that failed to add on the first service. So I don't think this a total memory problem.The modified the default DTM settings in DTM_Config.h running on the BlueNRG-M2 as follows:#define DTM_NUM_LINK           2 // Was 8#define DTM_NUM_GATT_SERVICES  5 // Was 8#define DTM_NUM_GATT_ATTRIBUTES 125 // Was 68#define ATT_VALUE_ARRAY_SIZE   (3000) // Was 1248I still see the error.

How can I use frequency hopping application of STM32WLE5? due to I didn't find any information on the website, but this function show on the firmware package. Could you please help us?thanks a lot.​

Hi, in the datasheet of the BL072Z board says: (pag 17)"LD5 = Green when communication "But when I connect the board with the UART port to program and see the data in the terminal the LD5 is in red color and everything works ok, but then the LD5 sometimes turn on green and the node stop working, I had to reconnect it to restart the Tx, why?thanks

Hello! I am trying to download the FUS V1.1.0.0 to a STM32WB5xE controller through SWD in CubeProgrammer so as to update the firmware. But I receive Error: --Reserved-- . I ignored it and downloaded the firmware successfuly but my BLE stack doesn't work :( . I have soldered the controller in my board and connected some peripherals to him and everything is working ех�?еpt BLE. What can I do?

Hi, is there any reason why the BL072Z node sometimes loses downlinks?, I am using a single channel gateway working in the 868.1MHz frequency and I have modified the three default channels of the BL072Z node to this frequency, in the uplinks I have no issues but in the downlinks yes, does anybody knows why?thanks

Add more details here regarding the question.

I want to find some example of stm32WL.1:in the AN5408 Migrating from STM32L0, STM32L1, STM32L4 Series associated with SX12xxradio, to STM32WLEx microcontrollers, LoRaWAN projects can be found under Projects\NUCLEO-WL55JC\Applications\LoRaWAN,I can not find it ,where I can download?2: I install the cueIDE ,i can not support the The target device 'STM32WLE5JCIx' is currently not supported by STM32CubeIDE.3 the keil5 IDE is also not support the STM32WL.how can I start my first application?

I want to do LoRaWAN FUOTA with STM32L4 MCU. So in the implementation it is mentioned the memory has two banks and one bank is used for previous image and one bank for new image. So my query is can we define the size of the bank?

Hello,I developed a PCB for a project using STM32WB55 and after getting it manufactured I am trying to connect it to the computer in order to run the code on it.However, when I connect it to the PC I cannot see the COM port for it. It seemly doesn't detect the COM port. All I can see is the DFU in FS Mode under Universal Serial Bus which I am not that sure what it is or how to make use of it. ( see picture below. Sorry for it being in French)I want to run the code on the PCB by using the bootloader, however in order to do that in to use the STM tools, I need to see the COM port. What do you think I should do?

Hello, everyone.I have a problem with the board B-L072Z-LRWAN1. I edited the End_Node project of I-CUBE-LRWAN in order to get some packets transmitted by a Decawave device connected to the B-L072-LRWAN1 board.Obviously, I connected the TX-RX pins of my Decawave device to the RX-TX pins of my board (USART1 PA10 - PA9). Such packets, once received and processed by the board, will be forwared to a Lora gateway for further processing. The communication between the end node and Lora gateway doesn't seem to give any problems; however, I don't get any packet transmitted by the Decawave device on my B-L072-LRWAN1 if I use USART1.I don't know why, but I believe that there are some problems with USART1 and the interrupt service routine. For debugging purposes, I also checked that the Decawave packets are correctly sent and printed to the USART2 (connecting the TX pin of my Decawave to the RX pin of USART2 - PA3) of the B-L072-LRWAN1 board.
