lr1110-rs

Rust library providing high-level access to the Semtech LR1110 transceiver's advanced features.

This crate extends the basic radio functionality provided by lora-phy with comprehensive access to the LR1110's unique capabilities.

Features

• system - System diagnostics (temperature, voltage, RNG, UID)
• gnss - GNSS scanning for geolocation (GPS/BeiDou)
• wifi - WiFi passive scanning for indoor positioning
• ranging - RTToF distance measurement
• bootloader - Firmware update utilities
• lr_fhss - LR-FHSS modulation support
• regmem - Direct register/memory access

Installation

[dependencies]
lr1110-rs = { version = "0.1", features = ["system", "gnss", "wifi"] }
lora-phy = { git = "https://github.com/lora-rs/lora-rs" }

Usage

use lr1110_rs::system::SystemExt;
use lr1110_rs::gnss::{GnssExt, GnssSearchMode, GNSS_GPS_MASK};
use lr1110_rs::wifi::{WifiExt, WifiSignalTypeScan, WIFI_ALL_CHANNELS_MASK};

// System info
let temp = radio.get_temp().await?;
let uid = radio.read_uid().await?;

// GNSS scan
radio.gnss_set_constellation(GNSS_GPS_MASK).await?;
radio.gnss_scan(GnssSearchMode::HighEffort, 0x07, 0).await?;

// WiFi scan
radio.wifi_scan(
    WifiSignalTypeScan::TypeBGN,
    WIFI_ALL_CHANNELS_MASK,
    WifiScanMode::Beacon,
    32, 1, 100, false
).await?;
