Hello guys,
I wan`t to make an project that send trough serial port a new image to flash my nrf9160.
By the moment I managed to send and recieve data but only on uart0.
So if someone could explain me a little more what is hapening and how can i fix next issues i`m stuck with:
1. When I send a buffer from my python script ( on COM port that coresponds to uart0) I recieve only byte by byte not the whole string at once.
2. When I send back and string to the same port my soft goes in a infinite loop that sends the same message.
3. When I try to use uart1 I see no activity on none of 3 COM ports that are assigned to the pc when I connect my board.
Here is the code I`m using for uart :
in main() :
uart = device_get_binding("UART_0");
if (!uart)
{
printk("Herror\r\n"); // error happens.
}
uart_irq_callback_set(uart, uart_cb);
uart_irq_rx_enable(uart);
printk("UART loopback start!\n");
callback() :
static void uart_cb(struct device *x)
{
uart_irq_update(x);
int data_length = 0;
if (uart_irq_rx_ready(x)) {
data_length = uart_fifo_read(x, uart_buf, sizeof(uart_buf));
uart_buf[data_length] = 0;
}
}
and function used to send over uart:
void uart_sendCOM(struct device *x, u8_t *Cont)
{
u16_t len = strlen(Cont);
uart_fifo_fill(x, Cont,len );
uart_irq_tx_enable(x);
}
Thank you for help.
