I'm using 2 nrf51 DKs one as central and one as peripheral. I'm wondering if there is a defined time that a write takes to be registered on the peripheral?
This is a simple question: If I have a characteristic with, let's say an int16_t in it and catch the write event in a ble_gatts_evt_write_t structure - is the data field in...
