c - Microduino ENC28J60 Ethernet Module (Arduino compatible) UDP Send not working -

i using new microduino enc28j60 ethernet module (arduino compatible).

i using udplistener sketch , want echo message sender when udp packet arrives.

i receiving messages ok, udpsend in callback method not work.

this works fine on arduino uno ethernet shield

can help.

thanks in advance

here code:

===== additional information ====

hi,

sorry includes are:

include ethercard.h include ipaddress.h seem removed text left arrow & right arrow symbol used in c++.

i take note ether class. used example ethercard folder called "udplistener" , puzzled class not being declared. assumed in done in ethercard.h.

the program work , listens , displays correctly received udp packets udpserialprint method, listening side works. wanted echo sender of udp packet , udpsend not work.

the shield using on link: http://hobbycomponents.com/index.php/microduino-enc28j60-ethernet-module-arduino-compatible.html

the compatible libraries found through same webpage:

https://github.com/jcw/ethercard

i hope provides further info necessary.

first of all, posted code doesn't seem complete. there several incomplete #include's, also, don't see ether class defined.

next, if code use work on ethernet shield, libs used , more chip on ethernet shield?

the encj2860 "its own" chip. is, libs required control encj2860 might different ones used on ethernet shield, if , if, chip on ethernet shield not encj2860.

it impossible determine information given in question. but, first thing at.

p.s. working on sprucing libs encj2860, , waiting ethernet shield has encj2860, can this, or send libs (still debugged!!).
