💬 Building an Ethernet Gateway

numanx

Maybe you have the ENC28J60 module which is different than w5100.

try this code at the beginning of your sketch(using a mysensor's example)

you have to change the ip to match your subnet and try to ping it.

You can find the correct pinout here http://s3.electrodragon.com/wp-content/uploads/2011/11/172004eierrfwri9xsfamq-11.jpg

#define MY_GATEWAY_ENC28J60
#define MY_IP_ADDRESS 192,168,1,66  
#define MY_PORT 5003   
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
#include <UIPEthernet.h>```

i'm sure it's w5100 it's label on chip

@Mitja-Blazinsek exactly the same module I have. Funduino right? Is working here

gohan

Look at THIS page, half way down, there is the picture where to solder the 2 resistors.

Ed1500

@Mitja-Blazinsek I went back to what I have done to get that module to work and I remember the only thing I had to do was add a delay in the setup, as most problems with that funduino board seem to be because of a Reset problem:
with this setup It works for me:

void setup() {
// setup ethernet communication using DHCP
delay(250); /// <-------- THAT ONE, BEFORE your ethernet.begin statement
if (Ethernet.begin(mac) == 0) {
//Serial.println(F("Unable to configure Ethernet using DHCP"));
for (;;);
}

Forget about "changing the 510 resistors" that is something that is valid for some shields, not for the Funduino module.
I only have the Miso,Mosi,SCK and NSS connected (and Vcc/ground ofcourse). NOT the RST. Besides, if you connect RST you cannot upload sketches as your Arduino will continuously reset

Ed1500

@Mitja-Blazinsek Is your problem solved now Mitja?
connecting stand alone W5100 to ethernet should be solved by the delay i advised. I guess it should work with rfm69 if you set up the software SPI as described, but if you want to use hardware SPI a slight modification is necessary, which i described earlier

I am not sure where I went wrong the below code hangs half way through. I am using ENC28J60

sorry, but that is not the complete code.

Ed1500

@hiddenuser That is too bad.
I must say I find your sketch somewhat confusing. What is the purpose of the ifndef confif_h followed by a config_h?

your config.h seems to just define the configuration. Why not just do an #include "config.h"
The large amount of ifdefs make the sketch a little bit hard to read.
If you are a beginner (we all have been) and make a sketch primarily for yourself, many of those ifdes are not really necessary and at least you are not losing track.
Anyway, not trying to criticize you, but error tracking also for yrself would be easier.
Also... you are using a soft SPI. For the ENC28J60 that is not really necessary. (not necessary for w5100 either with a little adaptation).
So... I am afraid that at this point I cant say anything sensible about yr sketch, but I can say the ENC28J60 works, even with a shared SPI bus.
Have you tried a working W5100 sketch with simply changing Ethernet.h into UIPEthernet.h?

hiddenuser

@Ed1500 Thanks for you feedback. I have switched over to using W5100. However I have noticed that for some reason I am missing a data which is sent over nrf24. The gaps in the data are random and I can't seem to figure out why this is happening. BTW I am using domoticz on a pi to get the data. Initially I was using mysensor over usb to get the data and used to work fine. In order to get the update OTA I am trying to switch to ethernet Gateway and does not seem to work :(

Are you running domoticz on a raspberry? If so, you could skip the arduino and connect the radio on the rpi directly.

Ed1500

@hiddenuser Your code seems OK apart from the fact it doesnt seem to do anything. Randomly missing data when using an nrf24 could be due to data just not arriving over the link although with shot distance that is rare. Nevertheless you could disconnect the w5100 and check a serial.print for a while to see if data is still missing.
I dont have much experience using the soft spi, only using hardware SPI. You may want to consider Gohan' s suggestion

hiddenuser

@Ed1500 @gohan Thanks. I am trying to create an ehternet gateway so I can do OTAs.

Ed1500

@hiddenuser I understand. Not sure if that is possible through a W5100/arduino, I guess it is but might not be easy :-)

gohan

Ethernet gateway works either way, it is only a matter of personal taste. Personally I did go for the raspberry gw because I have less stuff around and I save an arduino board.

Jonathan Caes

Hi everyone,
Is it possible to build an ethernet gateway with a RFM69 radio module?
Because I tried this a while ago and that didn't work because of a software problem in the library's. Is that already solved or not?
Thanks!

gohan

With development branch it should be solved, but I still have to try

Ed1500

@Jonathan-Caes I did, with an RFM69HW an arduino pro mini and a funduino Ethernetmodule. Used the setup from computourist in github https://github.com/computourist/RFM69-MQTT-client

Toni Ramos

hello @Ed1500, i have the same problem as @Mitja-Blazinsek. i have a w5100 module (funduino), arduino pro mini and nrf24 radio. i try to use your tip, including a delay in setup() but it doen't work yet, the gateway isn't reached using ping. is necesary another change? did you move the setup() function in the program? thanks!!
