It's better to use the native API for sure. Unfortunately I have to use Arduino development platform - the only IDE I've managed to set to build and burn projects.

Could these examples help? https://github.com/espressif/ESP8266_RT ... ng_started

Connection to Access Point.

2021-11-10T14:54:29+08:00

At esp8266 start up it tries to connect to Access Point.

Code:

uint8_t UDP_Start(char* ssid, char* pass, uint16_t loc_port)
{
    uint32_t timeout = 0;

    if (WiFi.status() != WL_CONNECTED)
    {
        rt_parameters.wifi_mode = WIFI_STA;
        
        WiFi.mode(WIFI_STA);
        WiFi.begin(ssid, pass);

        if (sys_parameters.debug)
            Serial.println("Waiting for connection");
            
        while (WiFi.status() != WL_CONNECTED)
        {
            delay(DELAY_TICK);
            
            if (sys_parameters.debug)
                Serial.print('.');
            
            timeout++;
            if (timeout >= sys_parameters.ap_con_timeout)
            {
              if (sys_parameters.debug)
                Serial.println();
                
                return UDP_WIFI_ERR; 
            }
        }
        Serial.print("\nConnection time (ms) ");
        Serial.println(DELAY_TICK * timeout);
    }
    
    rt_parameters.wifi_status = WiFi.status();
    
    IPAddress ip_addr = WiFi.localIP();

    memcpy(sys_parameters.loc_ip, ip_addr, 4);
    
    if (sys_parameters.debug) 
    {
        Serial.print("Connected! IP address: ");
        Serial.println(ip_addr);
        Serial.printf("UDP server on port %d\n", loc_port);
    }
    
    if (udp.begin(loc_port) == 0)
        return UDP_CONNECT_ERR;

    return UDP_OK;
}

Sometimes it takes a reasonable amount of time - 6-10 seconds. Sometimes it takes 30-60 seconds. Sometimes it gets out on timeout with status
WL_CONNECT_FAILED
WL_NO_SSID_AVAIL
When it's WL_NO_SSID_AVAIL I do WiFi.scanNetworks() and see my Access Point.

How can I improve the situation?
