# RN2903
|
|
## A Rusty interface for the RN2903 LoRa module's serial protocol
|
|
|
|
The RN2903 is a LoRa and FSK transciever for the 915MHz ISM band, commonly used in USB
|
|
devices like the LoStik.
|
|
|
|
This crate provides a safe, idiomatic interface using cross-platform native serial
|
|
functionality via `serialport`. This supports, for instance, a LoStik connected to a USB
|
|
TTY or virtual COM port, or a RN2903 connected via a TTL serial interface.

|
|
|
|
## Example
|
|
|
|
For instance, here is a simple program which blinks the LoStik's LED using the RN2903's
|
|
GPIO functionality.
|
|
|
|
```rust
|
|
use rn2903::Rn2903;
|
|
use std::time::Duration;
|
|
use std::thread;
|
|
|
|
fn main() {
|
|
let mut txvr = Rn2903::new_at("/dev/ttyUSB0")
|
|
.expect("Could not open device. Error");
|
|
loop {
|
|
txvr.transact(b"sys set pindig GPIO10 0").unwrap();
|
|
thread::sleep(Duration::from_millis(1000));
|
|
txvr.transact(b"sys set pindig GPIO10 1").unwrap();
|
|
thread::sleep(Duration::from_millis(1000));
|
|
}
|
|
}
|
|
```
