I use ESB sample code ,change to do 8k sample rate ADC(10bit) and transport by ESB ,but overflow when output receive data to PC use uart at UARTE_BAUDRATE_BAUDRATE_Baud1M. All my data is about 16KB/s,Is there somthing wrong ?
I don't see any problem to achieve it. How do you test. The attached image in my answer above showing the time it take to send 20kB, it was about 30kB/s at 460800 bps (seems that the Segger chip doesn't support above 460800bps).
I also attached the test file. Replace the main.c with main.c in peripheral\serial to test.
