Telnet with 3 W5500 Servers and 1 W5500 Client - Failure to Connect to Switch

Hi Everybody,
This is my first post here. I spent some hours looking for a solution to this and was unable to find a configuration where there were 3 (more than one) listening servers and 1 client.
The client sends out information to one of the 3 servers depending on where in a machine it is. The client gets its information over I2C and then converts it to a LAN and then after it is received, it converts back to I2C. I was really struggling with long I2C lines and all that is bad about that.
This solution works but in the morning when the machine is started, one of the servers fails to connect to the switch. If I open the cover and hit the reset button, it will connect and work. I tried to add in a watchdog to reboot if there is a disconnected cable but after a failed boot, a hard reset is the only thing that works. I have thought about moving to a more robust watchdog but I really want to understand the root cause.
I have tried assigning a different port to each server but that was no better.

Here is a giff of the connection led (on the right sheild):

And my Server Code:

/*

Thanks for any help you may have.

HI, G_Johanson.

In the code, Subnet mask is 255.255.0.0. This is Class B network.
If you want to use (192.168.X.X) IP address, Subnet mask must be set 255.255.255.0

And Did you set different IP address each W5500?
The IP address and MAC address must be different for each W5500 chip.

If the problem is not resolved, please contact us again.
Thank you.

Hi dkay!
Thanks for the reply.
I will change the subnet and report back. I do have a different IP and MAC address for each.
This morning I had 2/3 of the ones on my desk not work so this is a duplicatable issue. :slightly_smiling_face:

Thanks!
Gary

Hi dkay,
I did a test with the 255.255.255.0 subnet and one of them did not start up (same issue).
Is there anything else I should look out for?

Thanks,
Gary

Just connect one chip which did not work.
If this work, your network information is wrong.

Did you check IP range?
You must fix first, second and third IP address value.
For example, communication is available in 192.168.1.1 ~ 192.168.1.255

If you know this thing, change the 4th IP value.
There may be equipment with the same IP.

Thank you.

The IP is ok. All 3 are different and within spec.
I have had one or two fail upon startup and not always the same one. This morning all started ok. The next time, perhaps not. Can you let me know what the state of leds means? Where they both flash in sequence (as in the giff)?

Thanks, Gary

Loop means while in C.
In the Client code, the loop function is empty.
Function “StartMoving” is used once in setup function.
Is it right operation you intended?
If you want to use your operation repeatably, you must design loop function correctly.

Also, I think “StartMoving” function is worked before “Ethernet.begin”.
And after “Ethernet.begin”, there is no operation about network communication.
After setting the network information, try to connect to the TCP server

Here is a reference code for Telnet client,
https://www.arduino.cc/en/Tutorial/TelnetClient

Thank you.

I see what you mean. The code works though. I believe the wire library manages “Wire.onReceive(StartMoving);”.
It does work when I send a i2c command to the client (every time). The main function of this client is translating i2c to lan. I did move the “Wire.onReceive(StartMoving);” to the “void loop()” as you have suggested.
I also moved some of the code from “StartMoving()” to the loop.

It seems to be running better. I will give it a bit and report back.

Thanks for you input! :slight_smile:

No success. Upon booting (turning on the power supply) I have the same issue.
The client does seem more prone to fail on boot.
If I press the reset on the shield, nothing changes but after resetting the UNO it will do a steady green.
Thanks, Gary

First, test your board with using other person’s successful project in arduino web.
Do not change anything and just download the code to board.
After reset, see the LED status.
If green LED is steady and orange LED is blinking, hardware is fine.

I think you should understand about TCP coummunication and W5500 work flow.
TCP connection is needed just once.

Ok. I have done as you suggested and have had a fail. In this case, I loaded the same sketch onto all 3 on my desk, careful to change the mac and IP addresses. I removed the network wires from 2 of them and turned on the power. The leds blinked in sequence as before (giff below). I disconnected the network wire and moved it to the other ones, one at a time and one of the others had the same fail. So I believe this issue has more to do with a failed Adruino boot up. Once I press reset, all is ok.
Do you think the shield is holding a pin low (or high) during boot up and making the issue more likely?
:confused:
I just don’t know…
Thanks!

Hello again!
Further to the above, I have added a full watchdog and monitored a pin on the Arduino and it seems it is running and did boot ok. (giff attached)
This only further confuses me. :confused:
Thanks, Gary

Hi, Gary.

There’s no holding situation from Ethernet shield.

It’s not general situation. I doubt your network environment.
I am testing the W5500 ethernet shield, I can’t make situation like you.
Please change your LAN cable or check the hub or router works well.
W5500 supports 10/100 Mbps ethernet.

Separately, you wrote code “Ethernet.begin(mac, ip, subnet);”.
But your “subnet” value sets DNS server IP.
check syntax.

Thanks,
DKay

Hi Dkay,

I have tried it with the example code and a simple crossover cable from one to another. The same issue persists. I have come to the realization that the power-up cycle on this shield is really the issue. I had provisions in my main Arduino project to send a hard reset to other Arduinos so that is what I have done. I have added a wire that just after power up, it is dragged low for some milliseconds and then disconnected. This resolves the issue. I felt this was avoidable earlier on but it proves to be the fastest solution. I really appreciate your help along the way and I hope that any others that experience this issue can read and perhaps add to this if it is solved another way.

Thanks again!
Gary
