Also adds associated error variants `CannotPause` and `BadResponse`, an associated helper function `Error::bad_response`, and the internal helper function `transact_expecting` which shortens function bodies for functions implementing simple handshake-like commands, like `mac resume`. |

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 blinks the LoStik's LED using the RN2903's GPIO functionality.
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));
}
}
