https://devzone.nordicsemi.com/f/nordic-q-a/29273/max-uart-baud-rateHi, What is the max custom baud rate for uart? I seen that we can use 2M baud rate but I need 3686400 baudrate can I use on nrf52 uart? how?

We have not tested the device outside of this range. If you experiment with different values in the baud rate register you might get higher baud rates, but you will not get any guarantees from Nordic that it will work and that it won&#39;t damage the IC.</p><div style="clear:both;"></div>
