osPriorityNone used in STM32WB example projects

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...

Resolved! STM32WBA55 VBAT PROBLEM

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...

Resolved! stm32wba65 and I-CUBE-LRWAN

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...

STM32WL blocked in RTC initialization

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_...

What are the differences in SubGHz calibration processing between STOP2 mode and Sleep mode?

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...

If it's possible to increase the payload by more than 20 bytes, FUOTA - App to STM32WB55

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...

STM32WB5MM-DK On-board i2c sensor polling and BLE

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 ...
