[nRF51822] UART overflown if BTLE transmmision.https://devzone.nordicsemi.com/f/nordic-q-a/2051/nrf51822-uart-overflown-if-btle-transmmisionHi In my project, we wanna transmit large amount of data from UART master to nRF5182, and then to iOS7. Baud rate is 19200. Feed-in speed is near 2KB/sec. BTLE transmission and UART receiving will be overlapped very frequently. I found UART data willen-USTelligent Community 13Tue, 01 Apr 2014 18:07:36 GMTRE: [nRF51822] UART overflown if BTLE transmmision.https://devzone.nordicsemi.com/thread/8800?ContentTypeID=1Tue, 01 Apr 2014 18:07:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:83c430ea-044a-44e8-9349-bfabfd2a5057John<p>Hi Jeffery,</p> <p>Unfortunately the UART does not support DMA which would be nice. I ran into problems with getting data across the UART as well. The solution was to enable hardware flow control so that the far end stops transmitting before you run out of receive buffers.</p> <p>There are a number of good threads in this forum on this topic if you search for UART topics.</p> <p>Regards, John</p><div style="clear:both;"></div>
