Problems with ENC28J60 losing connection/freezing (using UIPEthernet or etherShield)? READ THIS!

[axillent]

Hi!

Are any fix was applied to 1.4.1 EthernetGateway?

Just build it based on atmega128A (need more flash to implement DHCP later).
It is running without any issue for a day.

ha!

everyone have to care about the source. Have t measure the source current and have added a multimeter.This probably add very small voltage drop, but it was more than enough for ping to start loosing packets! It is very sensitive to the power source. After adding just 0.2V pings stop been lost.

You're saying that you got it back to life without doing a reset or interrupt the supply first?

I'm not looking for the extreme recovery abilities)
My steps are:

• multimeter added to measure current between +3.3V source and VCC pin on ENC shield

• power on

• result - many ping were lost

• power off

• 3.3V source was turned 0.2V up

• power on

• result - none of ping were lost

So glad to have found this thread! Sounds like the exact problem I've been having. Ethernet gateway, with enc28j60 shield would randomly stop responding to Vera, to telnet (on 5003) and to pings. Sometimes in hours, occasionally making it a few days. Looking at my sensors, the radio stack is still working fine, the Ethernet side of the GW is just a dead stick.

I replaced my UIPEthernet files with the ones from GitHub above, disabled DEBUG and UDP to get it to fit, re-compiled, and re-deployed. Will report back how it goes!

BTW - the statement above says: "•DON'T activate the DEBUG-flag in MyConfig.h because this definitely will 'break' the gateway." I had to turn off DEBUG to fit the code on my UNO anyway, but I'm curious to why having DEBUG on breaks gateways?? (I had DEBUG on in my previous version with the old UIPEthernet files.. Did it contribute to my issue?).

My Mega app was surviving maybe as much as 5 minutes using the UIPEthernet library for Arduino >= 1.5. I made the changes as you suggest noting in particular that the reset has to come first. It's now been running flawlessly for 48hrs. I have have great hopes for this continuing.

I don't understand why this is still not in the main distribution after so long.

Anyway many thanks for posting this solution. It's a lifesaver.

Thank you for this post! Saved the day!
Just for information, im using EtherShield, with this lib: https://github.com/jonoxer/etherShield/blob/master/enc28j60.c
(it has ugly limitations, but has the smallest memory requirement in my case)

The solution fits almost exactly, with some small modifications (around line 290):

   if( (enc28j60Read(EIR) & EIR_TXERIF) )
         {
            enc28j60WriteOp(ENC28J60_BIT_FIELD_SET, ECON1, ECON1_TXRST);
            enc28j60WriteOp(ENC28J60_BIT_FIELD_CLR, ECON1, ECON1_TXRST);
            enc28j60WriteOp(ENC28J60_BIT_FIELD_CLR, EIR, EIR_TXERIF); // Might be overkill but advised by Microchip Errata point 12, //MagKas 2014-10-25
         }

Thanks again!

HI! Thanks for the topic! I'm new on this forum and I'm using enc28j60 with UIPE Lib. I have a lot of hang-up in my sketch.
Can somebody tell me wich is the best adapter-library combination to make a secure client-server arduno based sensor?
enc28j60 O WIZNET5100? UIPEEthernet, Ethercard or EtherShield ?

The solution proposed is modify enc28j60.cpp about line 215

Enc28J60Network::sendPacket(memhandle handle)
.....
if( (readReg(EIR) & EIR_TXERIF) )
{
writeOp(ENC28J60_BIT_FIELD_CLR, ECON1, ECON1_TXRTS);
}
...
}

by

if( (enc28j60Read(EIR) & EIR_TXERIF) )
{
enc28j60WriteOp(ENC28J60_BIT_FIELD_SET, ECON1, ECON1_TXRST);
enc28j60WriteOp(ENC28J60_BIT_FIELD_CLR, ECON1, ECON1_TXRST);
enc28j60WriteOp(ENC28J60_BIT_FIELD_CLR, EIR, EIR_TXERIF);
}

It is correct???

Sorry for my English. Thanks again. Daniel

@amoarg69 AFAIK the Enc28J60 has no stable setup yet. Use the W5100.

[amoarg69]

@m26872 Thanks!
Wich library is better to use? UIPEthernet works well with W5100? I need a library that can handle client/server request.
Thanks very much!!!

[m26872]

@amoarg69 W5100 is also the Arduino standard Ethernet shield and hence works good with the Arduino standard Ethernet lib. Server/client exemples provided through Arduino IDE for the lib.

I choose to reply to this very old topic because I updated to the latest UIPEthernet and this issue is still happening to me. I was about to replace it with a W5100 but came across this and tried it, compiled, uploaded, and here it goes. 24 hours of continuous web serving using an Arduino Mega 2560 and still counting!

I wish this get incorporated into UIPEthernet

@mhdayusuf Do you have a copy of the changes you made? I am quite struggling to make it work and is not obvious to me what changes you made... Thanks.
