I download the demo project \nRF51_SDK_8.0.0_5fc2c3a\examples\peripheral\uart\uart.uvmpw to my nRF51-DK board, but uart didn't work,all 4 LEDs are on. Is there any mistake?

Hi Steven,
It is a loopback example for UART. you have to connect TX and RX pins together. here is the note from the example
/** @brief Function for testing UART loop back.
* @details Transmitts one character at a time to check if the data received from the loopback is same as the transmitted data.
* @note @ref TX_PIN_NUMBER must be connected to @ref RX_PIN_NUMBER)

Hi, Aryan! you mean that the p0.06 should be connected to p0.08 (nrf52840)? Thank you very much!
