NRF52810 BLE Glitch

Hi!

I'm trying to transfer data from UART to BLE in NRF52810. NRF52810 connects MSP430 controller via UART, MSP430 sends packet of 16 bytes lenght every 2ms (500 times in a second). UART baud rate is 460800 (NRF is uses 0x075F7000 constant).
NRF52810 uses UART with EasyDMA, SDK 16.0. NRF52810 receive packet and transfer it via BLE.
Regulary after transfer start (near 5 second) UART glitch happens - NRF_UARTE_EVENT_ERROR. And one byte from packet is missing.
Test without BLE transfer at 460800 work fine!
Test with BLE transfer at 115200 also work fine!
Test with BLE transfer at 460800 - failed!

What might be a reason? Is there enough performance of NRF52810 for this task?
