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 ...
Dear STMicroelectronics Team,I am writing to strongly condemn the way power consumption values are presented in the STM32WB55 datasheet.When I choose a wireless SoC, I do so because of its wireless capabilities. If I only needed a microcontroller, I ...
Hello,Looking at the HRS FreeRTOS example applications code for STM32WB55, I see several task configured with osPriorityNone as priority.This priority level is defined as meaning 'no priority, not initialized' in cmsis header.Why is it used here ? Ho...
I have a project for a battery-powered clock using the STM32WBA55 chip. The battery is replaceable; the device can sit unused on a shelf for up to 4 months without the battery. Since the STM32WBA55 doesn't have VBAT or VRTC pins, how can I keep the b...
NUCLEO WB55For an unknown reason I2C1 has just stopped working. The BLE & UART are working but the boards (I've tested on 2 identical boards) are no longer talking to the sensors via I2C.When I scope them up the traces for SCL & SDA are both flat lin...
I have a custom board with stm32wba65 processor. I also have an RFM95 LoRa module. I need to add LoRaWAN capability. I tried adding I-CUBE-LRWAN into my CubeMX but was not able to load it (not a recognised package).How can I get an ST or Semtech appr...
Hi, I'm working with a STM32WL5MOC with the STM32Cube FW_WL V1.4.0. In my main.c I have this initialization: MX_GPIO_Init(); MX_DMA_Init(); MX_RTC_Init(); MX_LPUART1_UART_Init(); MX_USART1_UART_Init(); MX_ADC_Init(); MX_CRC_Init(); MX_...
I found in my tests that for the same sequence of operations (Radio.SetChannel -> Radio.RadioSetTxGenericConfig -> Radio.Send), the time required differs significantly between waking up from STOP2 sleep mode and waking up from Sleep mode. Here is Rad...
A development collaborator on the application is trying to improve the performance of transmitting the payload between the app and the board containing the STM32WB55 microcontroller via BLE. He is asking if he can increase the size beyond 20 bytes in...
Hello guys.I have an STM32WB5MM-DK disco board and im trying to get familiar with the ble stack. What i want to do is create a p2p server, poll an onboard i2c temp sensor for data and send that data through ble. What i did at first (successfully)was ...
Greetings,I am trying my hands on STM32WLE5CCU6 and want to encrypt variable length data using inbuild encrypt hardware or feature of the controller. I am generating a byte array of variable length. Is it possible to encrypt that array ? In an exampl...
