Resolved! STM32WB15CC + FreeRTOS: BLE connection drops when writing configuration to internal Flash
Hardware: STM32 NUCLEO-WB15CC (STM32WB15CCUX) RTOS: FreeRTOS BLE stack: STM32WB WPAN / BLE via CPU2 (M0+) Hi, When writing a small configuration block (~48 bytes) to the internal Flash from CPU1 (M4 FreeRTOS task), the BLE connection drops immedi...
RTC in STM32WBA65 after reboot
I have an STM32WBA data logging project loosely based on the BLE heart rate project. I sync the RTC via either a BLE message, or NTP from a serial modem. All good; works well and the RTC timestamp ticks along whilst the code is in stop2 sleep. The de...
