STM32 MCUs Wireless

Hello, i am working with this kits and library. Using ping-pong example for learn but now i want to add a new uart then read gps datas and monitor on a screen. CubeMX have B-L072Z-LRWAN1 in board section. But after generate code you have just a idle code. Is there a option import I-CUBE-LRWAN library to CubeMX and use new peripherals.Thanks.

Hello,I'm using a I-NUCLEO-LRWAN1 shield plugged on a NUCLEO L073RZ board. I'm trying to make the I-CUBE-LRWAN AT-master example run on the Nucleo L073rz. As documentation explain i opened SB13 and SB14 and closed SB62 and SB63, i also redirected the stlink to the uart4 with flying wire to be able to program the board.To connect to my LoRa server i need to change my DEUI but the shield return an error "ERROR_INVALID_ARGUMENTS" (which is not even in the documentation of the software package) when i try to change it with the AT+EUI=XXXXXXXXXXXXXXXXX command. Does anyone have any idea on why we can't change the DEUI?

Hi,I'm using STM32 Lora Discovery kit to run the code generated by cubemx for RTC, While on debug i'm get the RTC values but when run normally then i'm not getting any values except the initialised values for the time.Thanks & Regards,Vijay Rakesh

could you give me any hints what changes are needed to convert IP64Router example from 6LPETH1 (Nucleo-F429ZI + X_NUCLEO-IDS01A4) into an IPv6 router ?

Does anyone use STM32WB55 now? The Reference Manuals is not available on this website.Neither KEIL nor IAR seem to support the chip�?

Hi, I am modifying the sample program End_Node on the kit B-L072Z-LRWAN1.UART2 is configured as a virtual com and works correctly on PA2 and PA3 pins. I'm trying to add a second serial on PA9 and PA10 but I can not receive and transmit anything. I then tried to modify the working virtual com to use the PA9 and PA10 pins but without success.The initial working configuration is as follows:#define USARTx USART2 #define USARTx_CLK_ENABLE() __USART2_CLK_ENABLE(); #define USARTx_RX_GPIO_CLK_ENABLE() __GPIOA_CLK_ENABLE() #define USARTx_TX_GPIO_CLK_ENABLE() __GPIOA_CLK_ENABLE() #define DMAx_CLK_ENABLE() __HAL_RCC_DMA1_CLK_ENABLE()   #define USARTx_FORCE_RESET() __USART2_FORCE_RESET() #define USARTx_RELEASE_RESET() __USART2_RELEASE_RESET()     #define USARTx_TX_PIN GPIO_PIN_2 #define USARTx_TX_GPIO_PORT GPIOA #define USARTx_TX_AF GPIO_AF4_USART2 #define USARTx_RX_PIN GPIO_PIN_3 #define USARTx_RX_GPIO_PORT GPIOA #define USARTx_RX_AF GPIO_AF4_USART2   /* Definition for USAR

We are looking at sending around 1Mb/s of data with a latency of under 1ms.

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).

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.

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 are wondering, how can it get access to the internet? Via USB?As I discovered, STM32F100 does have support for a S

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?
