💬 Building an Ethernet Gateway

[gohan]

What is the best way to make the gateway wait for ip address (it's set to use dhcp) when power goes down? I noticed that the gateway starts faster than the router and doesn't get the ip address so I had to push the reset button to get it to work.

[mfalkvidd]

@gohan maybe add a wait call in before()? Not sure if before() is run early enough, but it might be worth a try.

Maybe the library can be modified to try for a longer time before giving up.

[gohan]

Maybe I could make a check if there is no client connected I could reset the board, but I was wondering if there is any was to know if the system has a valid ip

hi after long time i finaly get new w5100 module now the test sketch from arduino ide for ethernet like web server are working fine bur still don't work as a gateway in domoticz or mycontroler. i just open example gatewayw5100 from my sensor libary and upload to mega bard bit status in my controler is always down af course i set the gateway in my controler :Enabled
Enabled
Type
Ethernet
Network type
MySensors
Connection details

[gohan]

Can you ping that ip? There are some faulty w5100 modules around and I did repair one by adding a couple of 100 ohms resistors on the ethernet pins.

[mfalkvidd]

@Mitja-Blazinsek is your local network using the same subnet (192.168.178)? What is the ip and netmask of your controller?

[Mitja Blazinsek]

my network is using 192.168.0 but i try to change the MY_IP_ADDRESS to 192.168.0.66 but still no responese. i dont know what is the ip of mycontroler it works only when ia write localhost:8443 i of domoticz was 127.0.0.1

[Mitja Blazinsek]

ok ip of mycontroler is 192.168.0.100

[Mitja Blazinsek]

is it maybe problem because i'm using mega board an i wired 50 51 52 pins but if i wired 11 12 13 like on the diagram here it not working the shield if i try dhcp address printer for test

[gohan]

You probably have faulty network shield

Sorry, but can't find any information about my problem about the gateaway.
For connecting a lot of binary switches etc. i took a mega and loaded a gateaway sketch from Mihai . Normally it runs very good, when i change the status flags from ON/Off to 1/0 (Don't know why?)
But now i had the idea, to disable the radio, because I don't need it for this mega.
Now the relais-switches do no longer work as before. They only work from time to time and rather randomly.
I want to switch and contol the switches with iOBroker, but without the radion connected and activated, it doesn't run.
Any idea?

[mfalkvidd]

@jopebe did you remove the define for the radio from your sketch?
What does the debug output say?

[jopebe]

Thank You for Your quick respons!
Yes, i made two slashes before the define-line of the radio .
I have no debug-output because I didnt engage myself in debugging until now. I will try it this evening. During the day Im engaged in other things.

Here thr output of the seriel monitor:

When I push the button in IoBroker-Vis, it takes often a lot of time until the LED is on; sometimes I have to push the button twice or more times; sometimes nothing happens at all.
When I define and connect the radio with the same sketch, it runs as expected.

@jopebe are the relays and switches locally attached to the GW? Please post your sketch

[Ed1500]

@scalz A very late reply, but someone else might be helped with it.
Hardware SPI is working.
The onnly thing is that on W5100 shield it will work without any problem but with most 5100 modules you need a small modification fixing w5100 problems

[Ed1500]

@fifo Most W5100 modules have a 5-3.3V regulator so if you connect the Vcc to 3V3 the chip just doesnt get enough juice

[jopebe]

I dont know, how to send my sketch as a file. Copy and past doesnt run.
I use an ethernet-shield and as I mentioned, when I connect and switch on the radio, everything is alrigth.

[jopebe]

Thank You to all, who tried to help.
I think, I found the solution:
There was this line in the sketch: "const unsigned long tUpdate=60000; //update interval"
When I changed the time to 6000, it runs as when as the radio was connected.
So it was probably missing some kind of "interrupt", which usually comes from the radio , when it listens to the nodes or so?

[Newzwaver]

hi everyone,

has the pin setup changed? it looks like it has from the sketch. I used a0, a1 and a2 for the radio.
