Nordic promised to have 1Mbps data rate. when i was trying to transfer data through UART. data is validated until 401600 (400kbps). when i configured UART to 1 Mbps, data is corrupted. when i was tryingen-USTelligent Community 13Mon, 29 Feb 2016 14:33:54 GMThttps://devzone.nordicsemi.com/thread/45138?ContentTypeID=1Mon, 29 Feb 2016 14:33:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d073120f-9e16-4e19-8a65-a0ce70c028e9Vidar Berg<p>Hi,</p> <p>Sorry for the slow response. Master control panel is using 1Mbaud, but was actually able to reproduce the behavior you described using the SDK example. It appears to be a SW issue and not HW. Tried the same with the simple uart module found in SDK 7.0.0, and got a throughput of ~40K characters per second running at 1MBaud with HWFC without any data loss.</p> <p>To test this I modified the SDK example do not exit upon receiving the &#39;Q/q&#39; character, then used Real term and sent a larger text file while having capture enabled. Afterwards I did a &#39;diff&#39; of the input and output file to verify the data.</p> <p>I&#39;ve reported this as a bug internally.</p><div style="clear:both;"></div>
