Ask questions and discuss STM32 wireless solutions and their implementation for running Bluetooth LE, Zigbee, LoRaWAN applications.
Dear all, The X-CUBE-MATTER Expansion Package is now available on our official website following this link MATTER - Matter software expansion for STM32Cube - STMicroelectronics It is a reference implementation for the demonstration of Matter on ST...
Please go and visit our wiki pages where you can find a lot of information on our wireless product families (WB, WBA, WL) and the supported protocols: BLE, Zigbee, Thread, Matter, Lora, ... To begin your technical journey, please start from this top ...
HiI am using STM32WL55I want to download firmware to MCU using system bootloader.I set pin4(PB6) to usart1_tx, and pin5(PB7) to usart1_rx.I installed Flash Loader Demonstrator Ver 2.8.0I set BOOT0 pin(PH13, pin19) to hight and then power up.(of cour...
Hello,Our Devices(50 devices) uses STM32WLE5CC and STM32WL V1.0.1 SDK. I have generated code with Lorawan. All system works perfectly for around 49 days, after that all devices get reboots.We found that it happens when HAL_Gettick() overflows(we send...
The hardware is B-L072Z-LRWAN1 kit.In STM32CubeExpansion_LRWAN_V1.3.1 I can change the Data rate and Tx power.But after update to STM32CubeExpansion_LRWAN_V2.1.0 I can't change data rate and tx power as I want.The data rate I change by edit LORAWAN_D...
Hello,As underflow of sub-second register RTC_SSR of STM32WLE5CC will takes 48 days.So, please guide us any method, can be used faster overflow of RTC_SSR, in least possible time.Thank You
We have two "P-NUCLEO-LRWAN1" bought several years ago, it is obsolete from ST,I try to play with LoRa, is "I-CUBE-LRWAN" still can work with those kit?
Hi, im currently working on a project for universtiy and im quite new to stm32. I hava a sensor on my board that coummuicates via UART, were it dumps its data once per second. My problem is that the first HAL_UART_RECEIVE works as intended, but after...
Hi,My custom device with custom firmware don't respond to LL_FEATURE_REQ so the device disconnect.The connectivity part of my project is very similar to the example BLE_p2p_server, the device start advertising and when I connect to it with the mobile...
Hi all, I am new to Lora technology and need some guidance from experts here.I am working on B-L072z LRWAN1 module that allows to transmits messages using Lora. I was able to download and flash the example code available in LRWAN library provided by...
Hello,When I try to start a new project with stm32wl MCU, I see that LoRaWAN is locked in cubeMX. When I import one pre-configured project, I see that it is enabled, but I don't know if I have to enable some other peripherals first to enable LoRaWAN ...
Hi there,I am using the STM32WLE4C8 and I am trying to write a safe handler for the NMI interrupt. From what I can tell, the NMI interrupt is triggered by a flash double ECC error, an HSE failure, or an SRAM parity error. All of these are fairly seri...
