Crate renik 

Embedded Device Configuration

This crate provides comprehensive configuration structures for embedded devices, specifically for Wi-Fi connectivity, Bluetooth device management, and device identification in no_std environments.

Features

• Wi-Fi Configuration: Store and manage Wi-Fi network credentials with WifiConfig
• Bluetooth Device Management: Complete Bluetooth device lifecycle management:
  • BluetoothDeviceInfo: Individual device information with pairing data
  • BluetoothDeviceList: Manage multiple paired devices (up to 10)
  • BluetoothConnectionState: Track connection status and link quality
  • BluetoothConnectionParams: Low-level connection parameters
  • BluetoothSecurityInfo: Security and authentication information
• Device Identity: Store device identification and authentication data with DeviceInfo
• Memory Safe: All structures use fixed-size buffers with length tracking
• Serializable: #[repr(C)] layout for easy persistence and IPC
• Embedded Ready: Full no_std compatibility with minimal dependencies

Quick Start

use renik::{BluetoothDeviceInfo, BluetoothDeviceList, WifiConfig};

// Wi-Fi configuration
let wifi = WifiConfig::new(b"MyNetwork", b"password123")?;

// Bluetooth device management
let mac_addr = [0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC];
let device = BluetoothDeviceInfo::new(&mac_addr, b"My Speaker")?;

let mut device_list = BluetoothDeviceList::default();
device_list.add_device(device)?;

All structures are designed for persistent storage and can be safely serialized to flash memory or other storage mediums for configuration persistence across device reboots.
