NRF_DRV_UART_EVT_ERROR

[MrFine]

Hi I use ble_app_uart sample SDK 12.3 test the data throughput, when use Nordic DK board , it can send near 5KB/s; but on my own board,the NRF_DRV_UART_EVT_ERROR will appear while receive the same amount of data from uart. why lead this and how can I fixed it?

the different between my own board and Nordic DK is the uart pin , when I changed the uart pin to 14,15,7,9(rx,tx, cts,rts), the Nordic DK will also appear NRF_DRV_UART_EVT_ERROR , so the uart pin must be the default? can`t 14,15,7,9(rx,tx, cts,rts) be a uart ?

Which chipset are you using? nRF51? nRF52? What have you connected the UART to? The Segger/J-Link chip? Do you have this chip on your custom board as well?

I use nRF51, and connect it to PC which run a serial port software that can send data to nRF51 by uart. the same test environment with nRF51 DK board and my custom board.

Connect it to PC how?

PC has COM port ， connect it to PC by COM port
