nRF51 <-> STM32 comunication via UART, max bauderate

[Mateusz Gancarczyk]

Hi, i have two microcontrollers: STM32F401 and nRF51822. They communicate by uart with flow control. I use 110 Soft Device from SDK 10. The maximum baud rate when communication work OK is 256000. When i try to communicate with speed 460k or 960k nRF51 receive wrong data. Data sent z STM32 is OK because i checked in logic analyzer. Could someone help?

Do you see this problem when there is some BLE activity at the same time, i.e advertising or in connected state? If you run a test without any BLE activity (no advertising and not in connected state), do you still see the same problem?
