If the task is not yet blocked on FreeRTOS_accept(), then this works just … WebYes, using the UARTE non-blocking TX/RX seems to work. The UART event handler passed to nrf_drv_uart_init() uses a semaphore to notify the RX task that data has been received, and the RX task sets up another receive using nrf_drv_uart_rx() , then the RX task waits on the semaphore again.
WebJul 22, 2024 · The opposition is true, the task falls asleep and gives up the CPU until it gets woken up by the OS e.g. when a semaphore the task blocks/sleeps on was signaled by an ISR or another task. The same applies to a blocking TCP recv (which internally uses a semaphore or something else to wait for network data to collect and return to the caller).
