Radio test example - UART pins

[Upright]

Hey there,

We are working with NRF52832 WLSCP package,

We had stated certification process , for BQB testing need to use the Radio test example with UART between EUT to the PC ( using a dongle or SDK)

As my new design does not use all required GPIO, Idon't have direct connection to connect UART pins

1. Is there a way to do the UART over BLE?

2. How to change the pins to fit my accessible GPIO's?

Default GPIO nRF52832	UART nRF52832	Interface MCU UART
P0.05	RTS	CTS	P0.07
P0.06	TXD	RXD	P0.08
P0.07	CTS	RTS	P0.05
P0.08	RXD	TXD	P0.06

Hi

Have you checked out the ble_app_uart example project where the uart_init() function initializes all four UART pins. Then you can set these to what ever pin numbers you'd like.

static void uart_init(void)

{

    uint32_t                     err_code;

    app_uart_comm_params_t const comm_params =

    {

        .rx_pin_no    = RX_PIN_NUMBER,

        .tx_pin_no    = TX_PIN_NUMBER,

        .rts_pin_no   = RTS_PIN_NUMBER,

        .cts_pin_no   = CTS_PIN_NUMBER,

        .flow_control = APP_UART_FLOW_CONTROL_DISABLED,

        .use_parity   = false,

#if defined (UART_PRESENT)

        .baud_rate    = NRF_UART_BAUDRATE_115200

#else

        .baud_rate    = NRF_UARTE_BAUDRATE_115200

#endif

    };



    APP_UART_FIFO_INIT(&comm_params,

                       UART_RX_BUF_SIZE,

                       UART_TX_BUF_SIZE,

                       uart_event_handle,

                       APP_IRQ_PRIORITY_LOWEST,

                       err_code);

    APP_ERROR_CHECK(err_code);

}

What SDK are you using for development, the nRF5 SDK or nRF Connect SDK? You need to create a custom board file for your project when creating an application for a custom board.

Best regards,

Simon

Not sure what do you mean by that i am using PCA10040

it shuold be DK

I simply need the code which will allow the EUTto communicate via different GPIO"S
