NetworkManager SysMod

Overview

The Network Manager module is responsible for managing the network state, including WiFi and Ethernet configuration, retries, and connection monitoring. It provides APIs to configure WiFi in both STA (Station) and AP (Access Point) modes, manage Ethernet settings, and monitor network status.

NetworkManager Settings

When constructed normally (in RaftCoreApp for instance) the NetworkManager is configured using the contents of the SysTypes key NetMan. The settings available to configure Network are described in Network Manager Settings

---

Constructor

NetworkManager::NetworkManager

• Parameters:
  • pModuleName: The name of the network module.
  • sysConfig: The system configuration object.

Initializes the Network Manager with the given module name and system configuration. It also sets the module as a singleton instance.

---

Setup

NetworkManager::setup

Sets up the network based on the provided configuration, including enabling WiFi STA and AP modes, setting SSID and password, and configuring the hostname.

• Steps:
  • Retrieves the network settings from the system configuration.
  • Sets the hostname based on the system's friendly name (if available).
  • Configures the network (WiFi STA/AP modes and Ethernet).
  • Logs the network configuration.
  • Configures WiFi STA and AP SSID and passwords.

---

Loop

NetworkManager::loop

The loop function is called frequently to service the network system and monitor changes in connection status. It triggers registered callbacks on status changes.

• Functionality:
  • Services the network system.
  • Checks for changes in connection status (whether an IP address is assigned).
  • Notifies registered callbacks if the status changes.

API Endpoints

The NetworkManager exposes several REST API endpoints to control network settings. These include configuring WiFi, scanning for networks, and managing WiFi credentials.

API List

The API for DeviceManager is included in the Raft API List

Endpoint	Method	Description
/w	GET	Setup WiFi in STA mode, e.g., /w/SSID/password.
/wap	GET	Setup WiFi in AP mode, e.g., /wap/SSID/password.
/wc	GET	Clear WiFi settings.
/wifipause	GET	Pause or resume WiFi, e.g., /wifipause/pause, /wifipause/resume.
/wifiscan	GET	Scan for WiFi networks, e.g., /wifiscan/start, /wifiscan/results.

JSON Status and Debug

NetworkManager::getStatusJSON

Returns the current network status in JSON format, including the system version and connection status.

• Example:

  {
    "rslt": "ok",
    "v": "1.0.0",
    "hostname": "mydevice"
  }
