fatal error: Wire.h: No such file or directorywhen trying.
_udp.beginPacket(some_ip, some_port); _udp.write(somedata, somedata.length); _udp.endPacket();
i think there is still a bug pending for udp.endPacket(); not returning an error
udp.write()returns the amount that was actually written to the TX buffer. You can check that and see if it matches what you wrote.
