Hi Nordic,
I used PIC32 for SPI Master and nRF51822 SPIS slave. I used shortcut for my spis in nRF51822 and I need to know the right time of acquiring the semaphore and let the SPI Master to avoid reciving DEF (default) character by master. Since the shoetcut for END and Acquire event is used how can I know what time is the best time for release the semaphore and tell the master that now it can send the data?
