Network layer implementation/client for ESP-AT implementing embedded-nal based on ATAT.
Currently, this crates offers the following features * Joining an WIFI access point, s. wifi module * TCP client stack (multi socket), s. stack module
Here's a simple example using a mocked AtClient:
````rust use std::str::FromStr; use embeddednal::{SocketAddr, TcpClientStack}; use espatnal::example::ExampleTimer; use espatnal::wifi::{Adapter, WifiAdapter}; use crate::espat_nal::example::ExampleAtClient as AtClient;
let client = AtClient::default(); // Creating adapter with 1024 bytes TX and 256 RX block size let mut adapter: Adapter<_, _, 1_000_000, 1024, 256> = Adapter::new(client, ExampleTimer::default());
// Joining WIFI access point let state = adapter.join("test_wifi", "secret").unwrap(); assert!(state.connected);
// Creating a TCP connection let mut socket = adapter.socket().unwrap(); adapter.connect(&mut socket, SocketAddr::from_str("10.0.0.1:21").unwrap()).unwrap();
// Sending some data adapter.send(&mut socket, b"hallo!").unwrap(); ````
To see a real-world example that runs on Linux, check out examples/linux.rs:
# For logging
export RUST_LOG=trace
cargo run --example linux --features "atat/log" -- \
