💬 Building an Ethernet Gateway

[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!!

[Ed1500]

@Toni-Ramos Sorry to hear that. Are you using Soft SPI or hardware SPI for both?
Can you get any connection if you just use it as webserver without the NRF24?

[Toni Ramos]

@Ed1500 i'm using softSPI as the example. I can see ping works correctly if i comment "#define MY_RADIO_NRF24". If not, the gateway shows the following messages continuosly:

0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1
0;255;3;0;9;TSM:INIT
0;255;3;0;9;TSF:WUR:MS=0
0;255;3;0;9;!TSM:INIT:TSP FAIL
0;255;3;0;9;TSM:FAIL:CNT=1
0;255;3;0;9;TSM:FAIL:PDT
0;255;3;0;9;TSM:FAIL:RE-INIT

[Toni Ramos]

@Ed1500 after tests with different versions of the library i discovered a bad welded pin in the nrf24. It seens to work fine now,i'll conect a node to the gateway and check all

[Ed1500]

@Toni-Ramos Glad you got it solved. apologies I had not seen yr earlier reply yet, but thats no longer relevant.
Always good to check the joints :-)

[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

[Mitja Blazinsek]

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

[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
