Connection to Access Point.

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

Code: Select all

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 statusWL_CONNECT_FAILEDWL_NO_SSID_AVAILWhen it's WL_NO_SSID_AVAIL I do WiFi.scanNetworks() and see my Access Point.How can I improve the situation?

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.
