Esp now and WiFi in AP mode are not working

Postby lalitahuja33 » Sun Nov 01, 2020 12:39 pm

I am trying to implement esp now with my existing code in which wifi is in AP mode. But the esp now and my existing code are not working together. The problem is with the wifi functions but I don't know what is wrong.

ESP NOW WiFi initialization function:-

Code: Select all


 void init_espnow_master(void)
{
    const wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK( nvs_flash_erase() );
        ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK( ret );
    tcpip_adapter_init();
    ESP_ERROR_CHECK( esp_event_loop_create_default() );
    ESP_ERROR_CHECK( esp_wifi_init(&cfg) );
    ESP_ERROR_CHECK( esp_wifi_set_storage(WIFI_STORAGE_RAM) );
    ESP_ERROR_CHECK( esp_wifi_set_mode(WIFI_MODE_AP) );
    ESP_ERROR_CHECK( esp_wifi_start() );
#if MY_ESPNOW_ENABLE_LONG_RANGE
    ESP_ERROR_CHECK( esp_wifi_set_protocol(MY_ESPNOW_WIFI_IF, WIFI_PROTOCOL_11B|WIFI_PROTOCOL_11G|WIFI_PROTOCOL_11N|WIFI_PROTOCOL_LR) );
#endif
    ESP_ERROR_CHECK( esp_now_init() );
    ESP_ERROR_CHECK( esp_now_register_recv_cb(recv_cb) );
    ESP_ERROR_CHECK( esp_now_set_pmk((const uint8_t *)MY_ESPNOW_PMK) );

    ESP_ERROR_CHECK( esp_now_register_send_cb(packet_sent_cb) );
    // Alter this if you want to specify the gateway mac, enable encyption, etc
    const esp_now_peer_info_t broadcast_destination = {
        .peer_addr = MY_RECEIVER_MAC,
        .channel = MY_ESPNOW_CHANNEL,
        .ifidx = ESP_IF_WIFI_AP
    };
    ESP_ERROR_CHECK( esp_now_add_peer(&broadcast_destination) );
}

WiFi in AP mode initialize functions in the existing code:-

Code: Select all

		//	INET		-	TCP-IP Adapter initialization
void INET_Configuration(void)
{
	tcpip_adapter_ip_info_t ipInfo;
	tcpip_adapter_dns_info_t dns_info;
	ip_addr_t dnsip;
	dnsip.type = IPADDR_TYPE_V4;
	IP4_ADDR(&dnsip.u_addr.ip4, 192,168,1,1);
	IP4_ADDR(&ipInfo.ip, 192,168,1,1);							//	Access Point IP Address
	IP4_ADDR(&ipInfo.ip, 192,168,1,1);							//	Access Point IP Address
	IP4_ADDR(&ipInfo.gw, 192,168,1,1);							//	Access Point Gateway
	IP4_ADDR(&ipInfo.netmask, 255,255,255,0);					//	Access Point Subnet
	IP4_ADDR(&dns_info.ip.u_addr.ip4, 192,168,1,1);			//	DNS Server address
	tcpip_adapter_init();
	tcpip_adapter_dhcps_stop(TCPIP_ADAPTER_IF_AP);
	tcpip_adapter_set_ip_info(TCPIP_ADAPTER_IF_AP, &ipInfo);
	tcpip_adapter_set_dns_info(TCPIP_ADAPTER_IF_AP, TCPIP_ADAPTER_DNS_MAIN, &dns_info) ;
	dns_init();
	tcpip_adapter_dhcps_start(TCPIP_ADAPTER_IF_AP);
}
		//	WiFi		-	WiFi Access Point Initialization
void WiFi_Configuration(void)
{
	uint8_t WiFi_MAC[6];
	wifi_init_config_t wconf = WIFI_INIT_CONFIG_DEFAULT();
	wifi_config_t sconf;
	esp_efuse_mac_get_default(WiFi_MAC);
	esp_event_loop_init(WiFi_EventHandler, NULL);
	esp_wifi_init(&wconf);
	esp_wifi_set_storage(WIFI_STORAGE_RAM);
	esp_wifi_set_mode(WIFI_MODE_AP);
	sprintf((char *)sconf.ap.ssid,"ESP32");
	sprintf((char *)sconf.ap.password,"alohomora");
	sconf.ap.ssid_len = 0;
	sconf.ap.channel = 10;
	sconf.ap.authmode = WIFI_AUTH_WPA2_PSK;
	sconf.ap.ssid_hidden = 0;
	sconf.ap.max_connection = 3;
	sconf.ap.beacon_interval = 2000;
	ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_AP,&sconf));
	ESP_ERROR_CHECK(esp_wifi_start());
}
		//	WEBS		-	HTTP Server Initialization
void WEBS_Configuration(void)
{
	httpd_config_t hconf = HTTPD_DEFAULT_CONFIG();
	hconf.max_uri_handlers = 16;
	httpd_start(&server,&hconf);

	httpd_register_uri_handler(server,&price_change_conf);
	httpd_register_uri_handler(server,&adv_set_login_conf);
	httpd_register_uri_handler(server,&advanced_settings_conf);
	httpd_register_uri_handler(server,&otapage_conf);
}
		//	NVSS		-	NON Volatile Storage Initialization
void NVSS_Configuration(void)
{
	esp_err_t ret;

	ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES) {
        ESP_ERROR_CHECK(nvs_flash_erase());
        ret = nvs_flash_init();
    }
	nvs_open("nvs",NVS_READWRITE,&hnvs);

	ret = nvs_flash_init_partition("nvsuser");
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES) {
        ESP_ERROR_CHECK(nvs_flash_erase_partition("nvsuser"));
        ret = nvs_flash_init_partition("nvsuser");
    }
	nvs_open("nvsuser",NVS_READWRITE,&hnvsuser);
}

How should I merge these functions so that both esp now and wifi in AP mode works together?
