UART communication

[sensorituk]

Hello there. Is there a non-blocking version of the UART blocking_read() function? Have browsed the libraries and documentation, but cannot find it.

Thanks.

Never mind. I am using can_read() and seems to work.

Guys, need some help here with the UART comms, please:

I need to implement UART communcations through UART (AT commands). The code is all ready to go, but I am finding issues with, possibly, the baud rate:

Initially, I tried to test the comms with the RS232 port (uart2, by default). Nothing happens, and no data is received from the module.
I hooked up the module directly onto a uart/usb adaptor, and I can read the data without any problems (or send commands)
I tried with uart1, pinmuxed to the RPi header as per below:

pinmux.output_pin_select(SonataPinmux::OutputPin::rph_txd0, 1);
pinmux.block_input_select(SonataPinmux::BlockInput::uart_1_rx, 1);

Nothing happens either.
Then I tried to communicate with uart2 directly from the laptop, using again the uart/usb adaptor. This time, if I send data from Sonata, it gets there, but it displays a gibberish, which means to me there might be a baud rate problem. This is how I initiate the uart (230400 baud rate):

auto uart = MMIO_CAPABILITY(Uart, uart2)
uart->init(230400);

I send and receive data with:

uart->blocking_write(c);
uart->can_read();

I've also tried with the blocking version of read, but still nothing.

Any help would be appreciated.
