Detailed Description

Coordinates Wi-Fi availability with independent service clients.

Each NetworkHandle is a scoped radio-use lease. The manager keeps the radio active while at least one lease exists and powers it down after the final lease and idle policy permit. This makes resource lifetime explicit and avoids one app disconnecting Wi-Fi while another service still needs it.

Constructor & Destructor Documentation

NetworkManager()

ersa::services::NetworkManager::NetworkManager ( events::EventBus &  bus = events::EventBus::instance(), hal::IWifiRadio *  wifi = nullptr  )

explicit

Bind a radio and event bus; null radio provides a no-hardware host mode.

Member Function Documentation

acquire()

void ersa::services::NetworkManager::acquire

(

)

Increment an unscoped reference count for legacy/manual lifetime code.

getActiveHandleCount()

size_t ersa::services::NetworkManager::getActiveHandleCount

(

)

const

Return the number of active network leases.

init()

Result< void > ersa::services::NetworkManager::init

(

)

Subscribe to link transitions and initialize radio state if available.

instance()

NetworkManager & ersa::services::NetworkManager::instance ( )

static

Return the installed process-wide network manager.

isConnected()

bool ersa::services::NetworkManager::isConnected

(

)

const

Return whether station networking is connected.

isConnecting()

bool ersa::services::NetworkManager::isConnecting

(

)

const

Return whether a station connection is being established.

release()

void ersa::services::NetworkManager::release

(

)

Decrement a prior raw acquisition; unmatched releases are ignored.

requestInternet()

NetworkHandle ersa::services::NetworkManager::requestInternet

(

)

Acquire an RAII lease; connectivity remains active until release.

setInstance()

void ersa::services::NetworkManager::setInstance ( NetworkManager *  instance )

static

Install the process-wide network manager.

tick()

void ersa::services::NetworkManager::tick

(

uint32_t

currentUptimeMs

)

Apply deferred link events and idle power-off using monotonic uptime.
