Hi, I am trying to connect a GPS through UART to nRF52 and get the reading and write it to the serial USB of my PC. I am using app_uart_init() and app_uart_close(). My idea is to init the GPS UART, get a reading, then close it; init the serial USB, write the GPS reading and close it. For now, I am just testing the code (init and close fns) without getting GPS readings, and with writing a standard text. I am getting junk character through the serial USB. Any idea ?
const app_uart_comm_params_t comm_params =
{
8,
6,
RTS_PIN_NUMBER,
CTS_PIN_NUMBER,
APP_UART_FLOW_CONTROL_ENABLED,
false,
UART_BAUDRATE_BAUDRATE_Baud115200
};
const app_uart_comm_params_t comm_params_GPS =
{
17,
18,
0,
1,
APP_UART_FLOW_CONTROL_DISABLED,
false,
UART_BAUDRATE_BAUDRATE_Baud115200
};
while(1){
APP_UART_FIFO_INIT(&comm_params_GPS,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle_GPS,
APP_IRQ_PRIORITY_LOW,
err_code);
app_uart_close();
APP_UART_FIFO_INIT(&comm_params,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle,
APP_IRQ_PRIORITY_LOW,
err_code);
printf("\nTest\n");
app_uart_close();
nrf_delay_ms(2000) ;
}
