Asynchronous Serial Host protocol, version 2
The official protocol description can be found at silabs.com.
This library provides the Actor struct which implements the actor model
for the ASHv2 protocol.
It is to be initialized with the underlying serial port ASH transmitter and response channel size.
use ashv2::{Actor, BaudRate, FlowControl, open};
use tokio::sync::mpsc::channel;
#[tokio::main]
async fn main() {
// Open the serial port connected to the NCP.
let serial_port = open("/dev/ttymxc3", BaudRate::RstCts, FlowControl::Hardware)
.expect("Failed to open serial port");
// Crate a communication channel with a specified size.
let (ash_tx, ash_rx) = channel(64);
// Create the ASHv2 actor, which returns the actor,
// a proxy to communicate with it, and a receiver for responses.
let (actor, proxy) = Actor::new(serial_port, ash_tx, 64).expect("Failed to create actor.");
// Spawn the actor's tasks to handle communication.
let (_transmitter_task, _receiver_task) = actor.spawn();
// Send a data frame to the NCP using the proxy.
// Example: EZSP version command
let request_data = vec![0x00, 0x00, 0x00, 0x02];
proxy
.send(request_data.into_iter().collect())
.await
.expect("Failed to send request")
.await
.expect("Failed to receive response")
.expect("Actor reported an error");
// Receive a response from the NCP.
if let Some(response) = receiver.recv().await {
println!("Received response: {response:?}");
}
}Expected result:
Received response: [0, 128, 0, 8, 2, 48, 106]
