💬 Building an Ethernet Gateway

[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?

@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.

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.

[mfalkvidd]

@Newzwaver Which sketch do you mean? The build page is still using a0, a1, a2 for W5100.

[Newzwaver]

Ok, I screwed up and downloaded the latest arduino software 1.8.3 and can't get my libraries to work correctly. I am trying to upgrade my sensors to 2.1.1 and rebuild my gateway using a new nano I put together. I am using the5100 connection with the radio wired to a0..... It the 1.8.3 not to be used for the overseas board?

I have just built a W5100 based Ethernet gateway using a pro mini, NRF24LR and I enabled Soft Signinig - using the latest mysensors github development version 2.2.0-beta I am getting Low on memory messages when I compile and load this - if I disable Signing it does not complain. I have noticed several random crashes with signing enabled however i have secure nodes so need singing support. Is there something I am doing wrong or is the latest dev image causing this to occur. I have Debugging all disabled and burning to a stock 5V 16Mhz device.

Sketch uses 25476 bytes (82%) of program storage space. Maximum is 30720 bytes.
Global variables use 1648 bytes (80%) of dynamic memory, leaving 400 bytes for local variables. Maximum is 2048 bytes.
Low memory available, stability problems may occur.

[mfalkvidd]

@itbeyond you'll need to find a way to save flash and ram, or use a microcontroller that has more flash and ram.

[gohan]

@itbeyond you could use a Mega 2560 or use a raspberry pi as gateway (if you already have one)

[itbeyond]

@mfalkvidd I this just how it is going to be on W5100 if we enable signing support - we must use a different chip? The Ethernet Gateway has nothing but the basic sketch with LED's enabled and soft signing.

[mfalkvidd]

@itbeyond probably. I guess the w5100 library uses a lot of ram and flash. The crypto for software signing uses a lot as well.

[Anticimex]

Atmga328p is not suitable as a gateway if you want ethernet and security. It simply does not have enough storage.
