Ethernet Gateway ....i am lost
I am also trying to build the ethernet gateway. I already have built a sensor (humidity and temp sensor) which is working and tested it with the serial gateway. For the gateway I am using a ardruino nano and a W5100 Ethernet module. (arduino 1.8.2 and board 1.6.11)
The trouble i am having is getting a valid IP-number. In my scetch (it is the default scetch from the mysensors page for the gateway) i defined the following IP
#define MY_IP_ADDRESS 192,168,1,108 // If this is disabled, DHCP is used to retrieve address
When i start my scetch, i am see the following information in the serial monitor:
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 OK 0;255;3;0;9;TSM:INIT:GW MODE 0;255;3;0;9;TSM:READY:ID=0,PAR=0,DIS=0 0;255;3;0;9;MCO:REG:NOT NEEDED IP: 0.168.1.108 0;255;3;0;9;MCO:BGN:STP 0;255;3;0;9;MCO:BGN:INIT OK,TSP=1 0;255;3;0;9;Eth: connect 0;255;3;0;9;Eth: disconnect 0;255;3;0;9;TSF:MSG:READ,100-100-0,s=1,c=1,t=0,pt=7,l=5,sg=0:19.0 0;255;3;0;9;TSF:MSG:READ,100-100-0,s=0,c=1,t=1,pt=7,l=5,sg=0:72.0 0;255;3;0;9;Eth: connect 0;255;3;0;9;Eth: disconnect 0;255;3;0;9;TSF:MSG:READ,100-100-0,s=0,c=1,t=1,pt=7,l=5,sg=0:71.0
as you can see the IP address is not correct, but it is receiving information from my temp/humidity sensor. Each time i reset the arduino i am getting a different value. Sometimes a part of my IP-address and sometimes just zeroes. In the page of my router with connected devices, i see sometimes new device with strange IP and part of de MAC-address.
does anyone have an idea?
@Mister_ik As you have the router, why don't you try with DHCP and lock an IP on Router for this gateway?
Other solution you may go with MQTT gateway.
Probably a stupid question, but thought I'd chime in... Since you don't show it above, are you also #define'ing a MAC address (like below)... Is the MAC address unique on your network? I've seen very odd things happen with duplicate MACs.
// The MAC address can be anything you want but should be unique on your network. // Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use. // Note that most of the Ardunio examples use "DEAD BEEF FEED" for the MAC address. #define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
You could also try other sketches that use w5100 module and see what they do, but try dhcp first.
@jkandasa I already tried to lock an IP address on the router, but that does not change anything
@stevebus Yes the MAC address is also defined and i tried already different MAC address, so i know for sure it cant be a duplicate MAC address
Could be a faulty module... Who knows... Did you try a different ethernet library version?
@gohan i am also affraid of a faulty module.....i am already waiting for new one to arrrive. i ordered now a ESP8266 version..hopefully more luck with that one.
I had the problem you describe, an ip address which was not the one it should be, usually a different one after each reset, sometimes with parts of the address recognisable as parts of the one I was expecting.
I too tried a different W5100 module, different arduino, different connecting wires. No better.
Then I found the answer, which was to supply the W5100 with 3.3v rather than the 5v I had been using. This fixed the problem completely.
It is very odd that supplying the module with 5v stops it working properly, I can't explain it. It has an onboard AMS117 to convert the supply voltage to the 3.3v the chip needs.
Whatever the reason though, it does fix the problem. I have two W5100 modules and neither will work properly if supplied with 5v. Both work perfectly on 3.3v.
I see the instructions for the Mysensors ethernet gateway show the module supplied with 3.3v so I guess when I thought I knew better I was wrong!
Hope this helps.
