https://devzone.nordicsemi.com/f/nordic-q-a/25136/is-there-a-way-to-use-uart0-without-interruptsHi, In Nordic nRF51822, (please correct me if I am wrong), after I transmit 1 byte of data (since the transmit fifo is 1 byte long and receive fifo is 6 bytes long), I can transmit the next byte only after I get an event telling me that the TX has happeneden-USTelligent Community 13Wed, 13 Sep 2017 01:04:31 GMThttps://devzone.nordicsemi.com/thread/99019?ContentTypeID=1Wed, 13 Sep 2017 01:04:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6a5a007d-3981-4b85-b319-960eace27b26RK<p>no there isn&#39;t. buy why is this a problem you just add a while loop between each character you send out which spins until TXRDY is set.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99018?ContentTypeID=1Wed, 13 Sep 2017 00:56:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:99bcba48-050f-4270-afe1-b6b9b580dabcnordicdev<p>Hi RK, thanks for the reply. Sorry about not being clear. My question was: is there a way to continously transmit via uart0 without worrying about checking for TXRDY event?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99017?ContentTypeID=1Wed, 13 Sep 2017 00:28:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ddec27d0-57de-495f-bc31-795c571918eeRK<p>If you are checking the TXRDY event has been set and waiting until it is set, how could you possibly be transmitting a byte before it&#39;s set?</p><div style="clear:both;"></div>
