Method 

Description 

~LUDP 

Destructor. LUDP will close resources when it is destroyed. 

available 

Number of remaining bytes in the current packet. Only meaningful after parsePacket() returns non-zero. 

begin 

Initializes UDP function, and start listening on specified local port. 

beginPacket 

Start constructing an UDP datagrams to a remote host specified by IP address and port. Call write() subsequently to construct the datagram content. Then call endPacket() to actually send it. 

beginPacket 

Start constructing an UDP datagrams to a remote host specified by URL address and port. Call write() subsequently to construct the datagram content. Then call endPacket() to actually send it. 

endPacket 

Send the datagram after calling beginPacket() and write(). 

flush 

Stop processing current packet. 

LUDP 

Constructor. LUDP cannot be instantiated directly. Use LWiFiUDP or LGPRSUDP instead. 

parsePacket 

Check if there are incoming UDP datagrams. read() should be then used to actually read the data from packet. 

peek 

return the value of next available byte from current packet. The byte remains in the packet. 

read 

Read 1 byte from current packet after calling parsePacket(); 

read 

Read up to len bytes from current packet after calling parsePacket(); 

remoteIP 

retrieve the sender IP address of the current packet started by parsePacket() 

remotePort 

retrieve the sender port of the current packet started by parsePacket() 

stop 

Stop listening for UDP datagram and uninitializes UDP module. 

write 

Append 1 single byte into the datagram 

write 

Append a buffer into the datagram.
