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.
This crate is available under the GNU General Public License, version 3.0 only, and does not directly depend on unstable crates.
Example
For instance, here is a simple program which dumps all LoRa packets received.
use rn2903::{Rn2903, ModulationMode};
fn main() {
let mut txvr = Rn2903::new_at("/dev/ttyUSB0")
.expect("Could not open device. Error");
txvr.mac_pause().unwrap();
txvr.radio_set_modulation_mode(ModulationMode::LoRa).unwrap();
loop {
if let Some(packet) = txvr.radio_rx(65535).unwrap() {
println!("{:?}", packet);
}
}
}
