💬 Building an Ethernet Gateway

[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!!

[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

[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?
