When listening to multicast packets, replace udp.begin(port) with Udp.beginPacketMulticast(addr, port, WiFi.localIP()). When sending a multicast packet, replace udp.beginPacket(addr, port) with

WiFiUDP class supports sending and receiving multicast packets on STA interface.

WiFi.printDiag(Serial) will print out some diagnostic info.

WiFi.localIP() is for STA, WiFi.softAPIP() is for AP.

WiFi.macAddress(mac) is for STA, WiFi.softAPmacAddress(mac) is for AP.call WiFi.softAP(ssid, password) to set up a WPA2-PSK network (password should be at least 8 characters).call WiFi.softAP(ssid) to set up an open network.WiFi.mode(m): set mode to WIFI_AP, WIFI_STA, WIFI_AP_STA or WIFI_OFF.This is mostly similar to WiFi shield library.

Other libraries (not included with the IDE).

mDNS and DNS-SD responder (ESP8266mDNS library).

Include the library in your sketch by selecting Sketch > Include Library >.

Note that all libraries do not come with examples.

Open any included example sketches from File > Examples > in the top menu bar.

When the library has been installed you can do the following: Note that adding a library to the “libraries” folder in the sketchbook will override other previously installed library versions. Select the main folder (it should have the library’s name) and move it to the “libraries” folder inside your sketchbook. Go to the directory where you have downloaded the. If you’re using Arduino IDE 2, you may need to restart it for the library to be available. You will be prompted to select the library you want to add.

In the menu bar, go to Sketch > Include Library > Add. The Library Manager looks slightly different depending on what version of the IDE you are using. The latest version is selected by default. When you’ve found a library you want to install, click Install. You can review the description and author. This will usually take you to a reference page or repository for the libraryįind a library you want to install. To find more information about the library, click More info. The results are listed alphabetically, so you may need to scroll down the list.

IDE 1.x also has options to filter by Type and Topic.įind the library in the search results.

In IDE 2, you can also click on the button in the sidebar.įilter the available libraries by typing something (such as a library name) in the text field above the listed libraries.

In the menu bar, select Tools > Manage Libraries….

Learn how to add libraries to Arduino IDE. Libraries are a collection of code that provide extra functionality for use in sketches, for example when working with hardware or manipulating data.
