I'm trying to enter STOP2 mode to save energy but the MCU get stuck in the function HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI). I have cleared all EXTI pending flags and RTC flags, and disable all five wake up pins. The MCU is supposed to wake up vi...

Almost resolved : now I can get the ack at each transmission, but to get this, I have to re-transmit the message four times (it is always four re-transmissions), by enabling RE_TX option. What I do not understand is, why we need these 4 re-TX to rece...
