STM32 MCUs Wireless

Does the binary for the CM0 need to be at a specific offset in the flash or can it be any part of the flash memory map in the flash? (any part would make for an easy dl and the then the cm4f just points the cm0 there during init).

Error: ST-LINK error (DEV_TARGET_CMD_ERR) Error: Device not supportedflash loader C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin/FlashLoader/0x0.stldr is loaded

I see a lot of reference to VirtualWire or RadioHead library for using RF433Mhz ISM band links. But I haven't find a library for KEIL ARM MDK using CubeMX or HAL drivers.​

i need a development board of STM32WB. From where i can purchase or Is there Development board available .

I already have STM32WB55 Nucleo Pack. But I can't find reference manual or CubeMx package or examples for these microcontrollers.

void JumpToBootloader(void) { void (*SysMemBootJump)(void);   volatile uint32_t addr = 0x1FFF0000;   HAL_RCC_DeInit(); HAL_DeInit(); SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0;   __disable_irq(); __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH(); SysMemBootJump = (void (*)(void)) (*((uint32_t *)(addr + 4))); __set_MSP(*(uint32_t *)addr); SysMemBootJump(); }I am using STM32l072( B-L072Z-LRWAN1 Discovery kit).Trying to jump to Bootloader using above code .I am trying to flash code using usb to ttl board to port UART2(LPUART1) with Demonstrator GUI tool. After calling above function ,Demonstrator GUI tools is not able to connect to board.

It's not listed on the "Packages Manager" and when I try adding it manually from zip file downloaded from the I-CUBE-LRWAN website (version 1.2.1) I get an error saying "This Package version is not managed on this version of of STM32CubeMX".

I am using a modified version of the ping-pong example. I am able to go to sleep and wake up on button press in order to send a TX message to another B-L072 receiver. My issue is when I put the receiver to sleep I am unable to make it wake up from a RX interrupt. The RX interrupt from the internal transceiver never happens once I am in sleep mode. If I do not go to sleep, the RX interrupt received triggers from pin DBG_SX1275_DIO0. In sleep mode, it never goes high. I have stripped it down to not deinit, and init hardware. I have tried sleep, stop, and LP-run. When I jump into any low power mode I can not wake up from a RX interrupt, if I don't go into low power mode the RX interrupt always works. Anything else I should try?

I am using Nucleo-64 LR072Z board with GPS module(GPS Module TTL UART) by rhydolabz.With using HAL libraries i can send the NMEA PMTK commands but while receiving the Data from GPS module HAL_UART_Receive function gives HAL_ERROR....please help me through this..

HelloI m Electronics engineer in Turkey.I m designing bluetooth controlled led lamb. It must be controlled by phone ios and android. And it must connect each other.Would you advise me a module and application

Hi,I use the b-l072z-lrwan1 to make lora advertisment and it's work.I use the project AT_slave or END_Node.But i want to use the second uart USART1 and nothing work in the environment.If i just change the file B-L072Z-LRWAN1\Applications\LoRa\End_Node\Core\inc\mlm32l0xx_hw_confThe program launch but nothing appear on the UART.I make a project with 2 UART with STM32CubeMX and both work great (it's not a hardware problem)Someone could help me?

I have a combination of a Nucleo64 (STM32L053) with an X-NUCLEO-S2868AI S2-LP board.The program on it works fine, now I want to test to power from a battery. 3.6V I took out the jumpers that connect the processor to the ST-Link section, only the uart remains connected. (SWO and nRST are also still connected)Somehow I see strange things: there is power reaching the system, not enough to get things functional but there is a signal on the linethe strange thing is that the process runs, I have information that makes sense on the debug uart line, but no messages get emitted by the S2-LP, althow I see no error messages.

BS"DHi,I am new in the Lora world. I have the ST Lora EVAL(B-L072Z-LRWAN1) boards and I downloaded from ST the Software examples. One of them is the Ping-Pong application. The thing is that the application works, but after a time the receiver stops working. I have already uncommented the LOW_POWER_DISABLE and the problem persists...Is anyone working with these modules that can help me to solve this problem?Thx

Hello,​I am using 'B-l072z-lrwan1' EV kit to join server of LoRaWAN through gateway.​I understand where to use APPKEY and APPEUI provided by gateway server of LoRaWAN. But the EV kit do not join to server. I refer to example embedded code in 'https://www.st.com/en/evaluation-tools/b-l072z-lrwan1.html' I-CUBE-LRWAN. please provide me with normal procedure for joining to LoRaWAN server.Thanks, Regards.

I have a STm32WB55 Nucleo Pack with me, I am using MAC High Sierra 10+. Can you tell me the steps to get started or point out the right place to look for. I am very new to ST environment .Regards,Prasad.

Hello everyone!First let me introduce myself. I am an IT engineer from a company CREA Plus that is stationed in Ljubljana, Slovenia. I got assigned a project, that uses the STM32F100 chips.As I have no experience myself and am only getting information from the st.com web page. To describe the project and wishes:So, a company that trusted us the project, wants us to securely connect their IoT devices (they use the STM32F100 chip) to an Azure Iot Hub.There is a lot of documentation about ST and azure, but nothing specific for this chip.The question we have:Can we connect STM32F100 securely to the Azure Iot Hub with a x.509 certificateHow does and where would be suggested, for the chips to get the firmware with the certificates?As I can understand, the chips can be configured to automaticaly connect to the Azure Iot Hub?STM32F100 does not have a WIFI module, and with that, we ar

Hello, I use two Evaluation boards STEVAL-FKI433V2 and now there is a task to order simpler and more compact PCB. The STEVAL-FKIxxx Gerber archive https://www.st.com/resource/en/board_manufacturing_specification/steval-fki433v2_gerber.zipincludes the file STEVAL-FKI433V2.G1, which contains GROUND plain, as is described in STEVAL-FKI433V2.EXTREP. As I know, 4-layer PCB is simpler to order than 3-layer PCB.This PCB may be routed using only 2 layers.Question1: Has Evaluation board STEVAL-FKI433V2 three layers?Question2: Are the GROUND holes THROUGH or BLIND type (if the Plane GROUND layer is used)?Question3: Is the use of 2-layer PCB for S2-LP on 433MHz (without GROUND PLANE layer) a wrong decision?

Hi, I trying to use an STM21L073 Nucleo-64 with my custom board LoRa (SX1261). I use your code I CUBE LRWAN version 1.2.1. At this time I can see JOIN procedure start. The node send a request JOIN to our GW and GW send a Accept JOIN. But in Tera Term Terminal each time node send a JOIN request, I have this message "PHY txTimeOut". The node never send a message to accept JOIN from GW. (GW work with a different node). Do you have some advice ? Edouard

I am using LORAWAN and after I joined as OTA, how to join as ABP using the generated season keys which generated after joined OTA?I read before thatits better first to join as OTA then join as ABP using the generated keys.Also, how to change the TX data rate after joined the network?

Posted on January 09, 2018 at 11:19Hi everyone, I'm currently working with my team on a GSM/LoRa gateway with the B-L072Z-LRWAN1 board and we are facing some trouble on the LoRa part. Indeed we figured out that we needed to import the LoRa library from STM32CubeExpansion in our project but when we do, there are a lot of errors appearing due to unresolved includes (for example 'hw_conf.h' or 'debug.h') and we did not manage to find those files or to fix these issues, is there someone facing the same issue or with a solution? It would be much appreciated#stm32cubeexpansion #include-error #b-l072z-lrwan1

Hi!I have used the B-L072Z-LRWAN1 with the module CMWX1ZZABZ-091. I used the software from I-CUBE-LRWAN and it worked correctly. But now I am trying to test the module CMWX1ZZABZ-078 with the same software (the example of AT_slave). The communication via UART works fine but the RF seems to not work. Looking at the power consumption, it doesn't transmit or receive anything because the power consumption doesn't change. I thought it could be a drivers problem because -091 uses STM32L072 while -078 uses STM32L082, but I can't find the correct code for the -078. Could you please tell me how to program correctly the -078? Is there any software already for this module?Thank in advance!Marta

Quick Response is Appreciated

Hi,I'm flashing the CMWX1ZZABZ LoRa module (STM32L082) for the first time. I have JLink ARM Lite debugger. I connected to SWDIO, SWCLK, nRST and GND pins to the JLink debugger. But when I try to flash/erase the memory, it a message saying "***JLink Error: STM32: Connecting to CPU via connect under reset failed.". I pulled down the BOOT0 pin.Regards,Nishanth S

Hi STM,I am relatively new to the embedded (I have decent C++ background). So my question revolves around start exploring STM. My idea is to start with Nucleo board and some Wi-Fi expansion board. Can you, please advice what would proper combination of those two?Regards,Aleksandar
