I have the following setup:1 STM32WB based device (A) is configured as both master and slave A is connected to up to 4 slave devices (B) I need to implement RTC synchronization over BLE, and my initial approach is following:A smartphone that's connec...
Dear community,I recently faced a possible anomaly in Stm32 cube configuration when setting up the RTC alarm:the rtc alarm interrupt was firing immediatley during initialization.Everything was setup via Cube, no manual code involved.Problem begins im...
Hello,When activating STM32_WPAN in STM32CubeIDE for STM32WB, the prescaler of RTC is forced to CFG_RTC_ASYNCH_PRESCALER (value is 15) and CFG_RTC_SYNCH_PRESCALER ( value is 0x7FFF ).I am used to configure RTC on other STM32 products with 127 and 255...
Hello everyone,For my application, I need to record a time counter in flash memory, with a resolution of 1/10 of hour (eg. 6 minutes).Here is what I do :As I know there is a limitation for flash lifetime (10000 erase cycles), I built an algorithm whi...
Basically, my requirement is to run RTC to monitor actual date and time for various schedules to actuate the devices. Note that RTC configuration is provided via LoRaWAN downlink and timestamp after LoRaWAN join.Hence, I would need mix mode to run bo...
Hi,currently I am working with the NUCLEO-WL55JC1, using the STM32Cube FW_WL V1.3.0 and the LoRaWAN_End_Node example as base.My target is to keep the LoRa stack working as it is on the example, but also to use the RTC to store the current date and ti...
Hey folks,I'm having issues with the RTC's calendar function while using BLE. I would like to timestamp recorded data using the calendar function of the RTC and then transmit that data over Bluetooth. However, when I enable the Bluetooth middleware i...
I tried the RTC_Alarm example folder, at first it worked out well and I was able to view the output.But when I ran for the 2nd time without any changes in the code the execution stopped at HAL_RTC_Init ->> (if (HAL_RTC_Init (& RtcHandle)! = HAL_OK))...
Board: STM32WB55Software: RTC and BLEHello,I am trying to get a project set up on the above board. It needs BLE, USB and RTC seperately. I have the USB running with Bluetooth now thanks to a relatively recent post offering a means to fix the incompat...
