UART between nRF51422 and other MCU

[Romain]

I am using a nRF51422 (SDK 6.1.0 with S310) and i have a question about th UART.

I can send and receive data from/to an other MCU but i have to set different parameters to configure UART on 2 MCUs.

• nRF51 UART configuration:

  params.baud_rate = UART_BAUDRATE_BAUDRATE_Baud38400;

  params.tx_pin_no = TX_PIN_NUMBER;

  params.rx_pin_no = RX_PIN_NUMBER;

  params.rts_pin_no = RTS_PIN_NUMBER;

  params.cts_pin_no = CTS_PIN_NUMBER;

  params.use_parity = true;

  params.flow_control = APP_UART_FLOW_CONTROL_ENABLED;

• other MCU UART configuration:

BaudRate = 38400;

WordLength = UART_WORDLENGTH_9B; 9 bits????!!!

StopBits = UART_STOPBITS_1;

huart2.Init.Parity = UART_PARITY_EVEN;

huart2.Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS;

If i set 8 bits, i can't exchange data. For information, i am using app_uart_fifo.c

Thanks.

Hi. As I understand, you are able to send data using the configuration you mentioned. What is your question here?
