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 ...
I went from the v1.12.1 stack to the v1.13.3 stack and LE Privacy seems to be no longer working. It advertises, but always with the static random address, not a random resolvable address. Also, the address never changes. Anyone else seeing this? ...
Hello, Can you please point me to the factory settings of stm32wb55 pucleo board.I seem to have erased some sectors 1-192 and fiddled with some option bytes (nBOOT0) and nSWBOOT0Best Regards,D
Several BLE circuit design inquiries of the STM32WB55RG MCU.The BLE impedance requirement of this MCU is 50 ohm, and it is recommended to use LPF (MLPF-WB55-01E3). For the detailed circuit diagram, please refer to the fourth page of the attached file...
STM32WB55RGV6 connects ADS1299 by spi. And I choose spi2. There are three signas miso\ mosi and sck. SPI2 has two alternative: GPIO_AF3_SP2 and GPIO_AF5_SPI2.① STM32CUBEMX automatically generated miso(GPIO_AF3_SP2), mosi and sck(GPIO_AF5_SPI2).Initi...
I was trying to use the time server for a project on STM32WB55. I tried to use it in an empty project. When I tried to debug, this window pops up:The curious part of the problem is that this error seems to happen with the time cluster only: using ano...
The STM32CubeMX generate:```#define LCD_SPI_Send_DMA(rd, ln) BSP_ERROR_FEATURE_NOT_SUPPORTED```instead if I modify the generated DISPLAY/Target/lcd_conf.h with`#define LCD_SPI_Send_DMA BSP_SPI1_Send_DMA`seems work correctly.I am using:Nucle...
Hi, I use the nucleoWL (STM32WL which is based on STM32L4). I want to use LPWAN to communicate some measurements each day. I use I2C between MCU and sensors. If I try the Sigfox Push Button exemple, I have 2uA in stop2 mode but if I add I2C1 (thanks ...
I'm using verion 1.1.5 of the I-CUBE-LRWAN software and reading a few I2C sensors using the HAL_I2C functions. No issues when sensors are functioning properly; however, I have run into periodic sensor failure issues while testing, either permanent or...
In order to achieve minimum power drain on the B-L072Z-LRWAN1 discovery board, it is necessary to remove some solder bridgesSee: https://community.st.com/s/question/0D50X00009XkbSOSAZ/excess-current-consumption-running-bl072zlrwan1-from-batteryAnd:ht...
