It’s a shame you don’t have a donate button! I’d without a doubt donate to this fantastic blog! I suppose for now i’ll settle for bookmarking and adding your RSS feed to my Google account. I look forward to new updates and will share this blog with my …

My problem is about:
I use Arduino uno3+ ENC28J60 + DHT11 + two 7segment LED to display temperature and humidity and send data to host PC by UDP , all the hardware and sub-module test normal, the ENC28J60 CS connect to D10, the measured power supply voltage for ENC28J60 is 3.3V, The IDE with the 1.03 version, EtherCard with the latest version. all functions in normal when I running wireshake to capture data on host PC,I got correctly display of temperature and humidity and the received UDP data is OK, but when I stop capture data with wireshake,the host computer can not receive any data.

I’ve try several different program on host PC and got the same result.
When I do the capturing with winshake, the program I use to receive UDP data can got correct result, when I stop capturing with winshake, the program I use to receive UDP data can’t received any data.

I do a test by replace ENC28J60 with W5100 ,I got a correct result without runing winshask.
Compare with the w5100 code I think the code for UDP in ethercard maybe short of something for bind sport to dport,but I don’t know how to modify the ethercard library. I also I don’t know how to use ether.udpTransmit() for Transmit udp data,would tell me what possible with the problem or give me a example?

Thanks,

the code as below?

Thankyou so much for this libray and Ethercard creation, is AMAZING and very stable! THANKS

I hope you can update it

Bummer. What to do?
