STM32 MCUs Wireless

use STM32Club, configure STM32WB55 but fail to select LSE as RTC input.

Hi,I followed this setting herehttps://community.st.com/s/article/how-to-configure-the-rtc-to-wake-up-the-stm32-periodically-from-low-power-modesBut still not able to select LSE as RTC source. What steps I missed? Please help.Thanks!

Regarding RTC update in I-CUBE-LRWAN project

Greetings,I am working on the LoRaWAN Project and facing issues in updating RTC from a server/UART in LoRaWAN library.My code is getting stuck while updating RTC, I am recieving time and from UART through user input.RTC_TimeTypeDef set_time;RTC_DateT...

Hi, I'm trying to transmit information between two NucleoWL55JC1 boards using LoRa modulation, i.e only the SUBGHZ_PHY layer. I want to set up the peripherals and middleware with CubeMX and use the HAL SUBGHZ functions in the code section.

Unluckily, I haven't found indications as to which of this functions to use for a basic transmit/receive application. In the HAL documentation and inside the stm32wlxx_hal_subghz.c file the functions are described independently but there is no cont...

Resolved! RTC current time in milliseconds (display in 6 byte hex)

Hello,I am using an STM32WB55 and am trying to figure out how to get the current time including milliseconds using an RTC and display that time in 6 byte hex format. I would most likely call the GetTime() based of a millisecond timer if that is the ...

Resolved! Bugs in the stm32wlxx_hal_rtc.c file.

In my opinion there are two bugs HAL_RTC_SetTime(..) (p. 776) and HAL_RTC_GetTime(..) (p. 881)./* Check Binary mode ((32-bit free-running counter) */if (READ_BIT(RTC->ICSR, RTC_ICSR_BIN) != RTC_BINARY_ONLY)should be RTC_BINARY_ONLY instead of RTC_BIN...

Resolved! STM32WL RTC HANGS!

Hi Team,I'm facing some trap in the STM32WLE5 device during RTC init, some time RTC initialization works, some time it hangs in generated function "HAL_RTC_MspInit()" during HAL_NVIC_EnableIRQ(RTC_Alarm_IRQn). if any one faced this issue kindly let m...

Hi, I am using STM32WLE5CCU6 MCU and I am trying to enable RTC Wakeup Interrupt. I use HAL_NVIC_EnableIRQ(RTC_WKUP_IRQn) but seems like my code is stuck inside it. Any ideas what can be causing that?

Resolved! RTC Accuracy issue

Hello, we are working on new release of STM32WL "STM32Cube_FW_WL_V1.3.0". release which has introduced changes in RTC driver which we believe is fixed for the issue (RTC loosing time issue STMicroelectronics/STM32CubeH7#24 )But, after running RTC ove...

STM32WB15cc - Wake up periodically with RTC and check for event (battery charged), disable rtc if event has happened

I am trying to use as little power as possible, I want my board to wake up every 30 seconds or so, check if battery has been sufficiently charged, if not, go back to sleep, if it has then turn off rtc and do a function. Is it possible to disable rtc ...

Resolved! How do I implement RTC wakeup in STOP2 low power mode using the STM32WLE4C8 MCU?

I can make the RTC wakeup work in Standby mode, but not STOP2 mode.
