[SOLVED] "Send tweet with timestamp" sketch hangs, shows no activity

Projects Programming

Inside EthernetUdp.h :

#define UDP_TX_PACKET_MAX_SIZE 24

Your code:

const int NTP_PACKET_SIZE = 48; // NTP time stamp is in the first 48 bytes of the message

byte packetBuffer[NTP_PACKET_SIZE]; //buffer to hold incoming and outgoing packets

You may want to try increasing UDP_TX_PACKET_MAX_SIZE to 48 (in the library) and try again.
