It is currently not recommended to do blocking IO operations (network, serial, file) from TickerĬallback functions. Library for calling functions repeatedly with a certain period. WiFiServer, WiFiClient, and WiFiUDP behave mostly the same way as with WiFi shield library.įour samples are provided for this library. Sent to the multicast or unicast address. You can use udp.destinationIP() to tell whether the packet received was Udp.beginMulticast(WiFi.localIP(), multicast_ip_addr, port). 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 This is mostly similar to WiFi shield library.
