WiFi

Example Usage

// Basic
App.init_wifi("YOUR_SSID", "YOUR_PASSWORD");
// Manual IP
auto *wifi = App.init_wifi("YOUR_SSID", "YOUR_PASSWORD");
wifi->set_sta_manual_ip(ManualIP{
    .static_ip = IPAddress(192, 168, 178, 42),
    .gateway = IPAddress(192, 168, 178, 1),
    .subnet = IPAddress(255, 255, 255, 0)
});
// AP
wifi->set_ap("AP SSID", "Optional AP Password");

API Reference

WiFiComponent

class WiFiComponent : public Component

This component is responsible for managing the ESP WiFi interface.

Public Functions

WiFiComponent()

Construct a WiFiComponent.

void set_sta(const WiFiAp &ap)

Setup the STA (client) mode. The parameters define which station to connect to.

void set_ap(const WiFiAp &ap)

Setup an Access Point that should be created if no connection to a station can be made.

This can also be used without set_sta(). Then the AP will always be active.

If both STA and AP are defined, then both will be enabled at startup, but if a connection to a station can be made, the AP will be turned off again.

void set_hostname(std::string &&hostname)

Set the advertised hostname, defaults to the App name.

const std::string &get_hostname()
void start_connecting()
void check_connecting_finished()
void retry_connect()
bool can_proceed()
void set_reboot_timeout(uint32_t reboot_timeout)
bool is_connected()
void set_power_save_mode(WiFiPowerSaveMode power_save)

Set the power save option for the WiFi interface.

Options are:

  • WIFI_POWER_SAVE_NONE (default, least power saving)
  • WIFI_POWER_SAVE_LIGHT
  • WIFI_POWER_SAVE_HIGH (try to save as much power as possible)

Note that this can affect WiFi performance, for example a higher power saving option can increase the amount of random disconnects from the WiFi router.

Parameters
  • power_save: The power save mode.

void setup()

Setup WiFi interface.

void dump_config()
float get_setup_priority() const

WIFI setup_priority.

float get_loop_priority() const

priority of loop().

higher -> executed earlier

Defaults to 0.

Return
The loop priority of this component

void loop()

Reconnect WiFi if required.

bool has_sta() const
bool has_ap() const

Protected Functions

void setup_ap_config()
void print_connect_params_()
void on_wifi_event(system_event_id_t event, system_event_info_t info)

Used for logging WiFi events.
