W5100 Gateway hangs /freezes after some time.

[webstor]

It stopped crashing.
But the problems just switched.
Only one device is communicating with the Gateway. The other devices aren't working anymore. My Relays and one temp and hum sensor are not communicating any more.

And they are 5 meters away from the Gw.

@webstor I am pretty sure that will be some other problem.

as far as i am aware #define MY_GATEWAY_MAX_CLIENTS is not a setting for the number of nodes connected and is not needed in a standard Ethernet gateway with one controller, the default setting of 1 is all you need. I am running a w5100 gateway and am able to connect to multiple nodes without that line.

If you un-comment it do your nodes then connect as per normal again?

Maybe you could make a new post about #define MY_GATEWAY_MAX_CLIENTS and see if one of the MySensors devs can give a definite answer.

Have you tried fitting a larger capacitor to the nrf power connections. When I updated to v2.1.1 I had two nodes that were usually very stable start to loose connection now and then. I replaced the 4.7uf with a 47uf and now they are working well again.

Hi,

ok, starts to crash again. I replaced the whole hardware aswell.
Yes if I uncomment them, the nodes connect normal.

I'm not using v.2.1.1, my nodes and gateways are on v.2.0.0

The next step will be to use an esp8266 as gateway instead of the arduino uno.

Thanx.

[webstor]

I upgraded to 2.1.1 and I keep testing.

[webstor]

Ok, running on 2.1.1 and commented out the following lines:

#define MY_GATEWAY_MAX_CLIENTS 20

and

//#define MY_INCLUSION_BUTTON_FEATURE

is running now for three days and looks good that it will keep it that way.

thanx guys.

Hi,
I have the same issue, W5100 gateway freeze, seen my update to MySensor 2.1.1.
I use a static IP otherway it's the same code as @webstor I did removed both line and still gateway freeze (one day max ). Unlike @websor if I reset, gateway doesn't come back. I have to unplug the usb power.

I only have five sensor, with only one battery powered. I used IDE 1.8.2 and AVR 1.6.18. Everything was working well with MySensor 2.0.0, IDE 1.6.9 , AVR 1.6.15. Any idea what could I look at ?

[gohan]

Try to restore previous versions of avr and mysensors one at a time and see if you see any changes. Did you check how much free memory it reports after you compiled?

[webstor]

when you say freezes: Do you mean it hangs totally, which means it isn't pingable @ all?
Or just won't accept connections from the sensors?

[Fraid]

Thank for the hint, I was able to invested the issue more. Here the result:

@gohan

Sketch uses 19560 bytes (60%) of program storage space. Maximum is 32256 bytes.
Global variables use 981 bytes (47%) of dynamic memory, leaving 1067 bytes for local variables. Maximum is 2048 bytes.

@webstor No it's pingable but their some timeout.

Same test after reset, GW keep dropping but this time with max of 2 drop per ten ping. Other devices (phone, bridge etc...) can be pinged without timeout and I'm on the same network.

For the communication testing, I'm sending payload to my tv sensor, and I made a video showing the GW status led when he doesn't work:
and
After reset

Look like it's a reset on the first video?

Next test, new sketch with debug on, sending same payload, GW always receive something like:

0;255;3;0;9;Eth: 2;3;1;0;32;10
0;255;3;0;9;TSF:MSG:SEND,0-0-2-2,s=3,c=1,t=32,pt=0,l=2,sg=0,ft=0,st=OK:10

Some time even when payload is received, TV doesn't turn on, also tested with a simple light sensor. GW and TV are in the same room.

So look like GW is dropping some message, I'll try tomorrow to get back to previous AVR, if their no hint.

Hi guys, I may found the issue.

GW was powered from the NAS (for month) and I switched for a wall adapter. Now I'm able to ping GW without timeout...sorry (I see you guys coming....obviously it's a power issue :D !). GW has been running for one days now.

Note: I'm using AVR 1.6.16 now, but i'm pretty sure, power was the real issue.
