Pygate - ethernet reliability issues
-
Hi,
Been using my pygate with POE for a while now and I notice that it frequently stops communications over ethernet and has to be reset or power cycled to get it to work again. My code is based on the examples in the documentation.
I've not tried the same tests with wifi yet.
Has anyone else experienced this?
Thanks
Andrew

Hi @Richard-Martineau
Over the last weeks we did some tests with the method you describe, but unfortunately no resolution there :(
-
The only issue I can think of here right now, is that the USB 'communication' is the potential issue here (I cannot see a reason how it would be related to the power distribution of the PoE and USB devices, but you probably know about Murphy's law). Could you perhaps try a USB cable without communication link (or like connected to a powerbank?)

@Richard-Martineau said in Pygate - ethernet reliability issues:
I was using an Ethernet cable with the POE adapter, without providing power(POE), and also using a USB cable to power up the PYGATE, .... I had all kind of problems.
Since I removed the USB cable, and replaced it with a POE injector over the Ethernet cable only, .... storm is over.If this helps, I still think it should be fixed without the Po. I do not want to use PoE I just need the E from it..
-
Interesting... I'll have to try that for myself, thanks! (also tagging @peterp in this)

Hi,
my 2 cents concerning this issue...

Hi,
ok. I can confirm that the PyGate with WiPy3 stops responding to PING requests a few minutes after startup with PoE.
But I can't confirm that the PyGate didn't work anymore. The Gateways status within the TTN Console is updated every 30 Seconds or so for the last 15 days.Hi,

@jcaron said in Pygate - ethernet reliability issues:
Meanwhile, I investigated a bit further:
It seems RX related.
I come to this conclusion because of the following:
I have a few Lora devices. They can only join the LoraWAN network just after a reset of the Pygate. For joining a LoraWAN network it seems the Lora device should be able to receive a packet back. That stops functioning after a while.
This correlates with ICMP pings getting slower and slower until they timeout and no longer work (and will never work again).
It seems packets no longer arrive at the Pygate, but it can still send data from a (wireless) Lora device to the LoraWAN (TTN) backend. So TX remains operational. I also see this (packet wise) behavior while sniffing the network. I also notice the >>> console getting very slow if this problem is present.With this in mind, I understand people state that the Pygate will remain operational because Lora packets keep arriving at the LoraWAN backbend (TTN for example), but I think this claim is not true in some noisy networks because packets from the backend are not getting back through the Pygate gateway to wireless LoraWAN devices.
Unfortunately, I do not have time to investigate myself in more detail at the moment, but - if desirable - I could produce some excerpts of the broadcast packets which are normally present on my network and which could trigger this problem.
-
I am on a noisy network. I could also try moving to a less noisy network (although I would argue that a device should not get slower by receiving some broadcasts; we are talking about 0.5-1kbyte/s here.). And we are not always in control of the networks we should be connecting to.
-
@Jaap-Crezee This looks like a good starting point. You probably want to add a loop and send a counter in the client, and print the counter on both client (TX and RX) and on the server, with timestamps.
It's regular Python but I don't think there's much to change.

@jcaron @gijs @peterp
I tried another network on an (much) older sitecom 10/100mbps switch connected to my computer on a different ethernet port.
That network does not have the noise which is present on my "normal" office lan.I am now seeing this:

Doesn't this still ring a bell? I could potentially debug this, but there is currently not enough datasheet information available about components used, especially the POE module. I couldn't even find information regarding the required POE voltage and typical current usages. But that's a bit offtopic for now.PS 15 minutes later without the other lan:

Otherwise it could be quite a long debug. As stated above, I would start by trying to determine if the issue is on the RX or TX side, by either switching on Ethernet on the WiPy or using a simple UDP echo sever with logging, to see if the delay (and loss) happens on one side or the other.
Do we have some Pycom/python examples at hand to try within 30 seconds?
-
@Jaap-Crezee you may want to try a direct connection to your computer to see what happens if there’s no (or little, some computers can be quite chatty) other traffic. You would also probably get information about Ethernet issues via ifconfig stats. I would also run a tcpdump during the ping tests to see if there’s anything else going on.
Mmmmmhhh just wondering if we’re not faced with a good old duplex negotiation issue. Haven’t seen one in nearly two decades, but a mixup between half and full duplex can lead to similar terrible performance. Not quite sure it would lead to that weird latency, though.

After that... there are quite a few places where there could be issues so it’s going to be quite some work to pinpoint it. I’m really puzzled by the recurring 7-8 second latency though. I have a hard time trying to guess where that could possibly come from.

@Gijs @peterp @jcaron I tried both wifi_on_boot & pybytes_on_boot without any difference, unfortunately.
I am not only seeing ICMP "slowness", FTP is also very slow as is telnet which makes me suspicious about the network functionality in general:[jaap@jaap /data/work/gateway ]$ wget ftp://micro:python@10.0.0.99/flash/boot.py --2020-11-20 22:12:43-- ftp://micro:*password*@10.0.0.99/flash/boot.py => 'boot.py.1' Connecting to 10.0.0.99:21... connected.

Having said that, if that does help anyway, we are seeing some kind of race- or timing-condition issue.
Either one should probably be investigated in more detail, identified, and fixed somehow. Because currently, this prevents me from determining if the Pycom hardware (& software) would be a viable solution for us; it should provide stable LoraWan gateway functionality.PS the switch is a "normal" unmanaged TP-Link TL-SG103 8 port 10/100/1000Mbps switch which has proven to be stable for any device which I connected to it the last two years until I connected this pygate + pycom + poe module.
I have tried multiple cables which are known to be okay.
PS2 I somewhat recognize this behavior from previous projects involving an Arduino & ENC28J60 SPI ethernet Module...

We had some good experiences with that, but it did not resolve the issue completely. We also tried simulating a noisy network here, but that did not 'improve' our slow-ping time starting delay unfortunately
Let me know of your results!

Thank you for your inputs. I will try the two disable commands. Could it also be related to receiving a lot of UDP broadcast messages?
I am on a noisy network. I could also try moving to a less noisy network (although I would argue that a device should not get slower by receiving some broadcasts; we are talking about 0.5-1kbyte/s here.). And we are not always in control of the networks we should be connecting to.
I will get back once I have some results.

@Jaap-Crezee We are (sort of) aware of this issue and we can reproduce it, but we have not been able to ' trigger' slow ping times on demand. My colleague @peterp looked into this for a long time, but we could not pinpoint the cause of it. In our case, it takes hours or even days before it gets into this state when pinging the device. It seems yours gets in this state of slow ping responses relatively quickly. Now the only difference between your setup and ours, is in the network infrastructure (I believe), making me believe the issue can be found there.
The suggestions of @jcaron sound like a good place to start (I think we evaluated that as well, but I dont remember the outcome exactly). We tried a whole assortment of solutions but none have resulted in a proper triggered reproduction.
Note that we are not able to reproduce it when using the product as it was meant to be (A LoRa gateway connected through wired internet / PoE), only when we are throwing pings at it.
Let me know if you have any suggestions!
Gijs
-
@Jaap-Crezee Have you tried setting
wifi_on_boot(false)? Though this could possibly explain the initial packet loss, but probably not the 8 second latency and later packet loss!Also I believe Pygate builds don't include Pybytes, but if they do,
pybytes_on_boot(false)would be a good idea.It would probably be interesting to run a simple UDP client+server to check in which direction the packet loss/latency occurs.
Is the Ethernet switch managed? Do you see any errors or link bounces on that?

@Gijs Dear Pycom,
I have got a new Pygate, Wipy & POE module connected and fully updated to the latest (stable) firmware as of this evening.
I am using a 5V 2.5A USB power supply connected to the USB-C port of the PyGate.
There is an ethernet connection to a 1Gbps switch on my desk which works perfectly fine with other devices.
I am having this code in my device:[jaap@jaap ~ ]$ curl ftp://micro:python@10.0.0.99/flash/boot.py # boot.py -- run on boot-up from network import ETH e = ETH() e.ifconfig(config=('10.0.0.99', '255.255.0.0', '10.0.0.1', '10.0.0.1'))[jaap@jaap ~ ]$ curl ftp://micro:python@10.0.0.99/flash/main.py # main.py -- put your code here!No more. No gateway yet.
Now I am seeing this erratic behaviour:

Good to hear the issue got solved!
I believe there are still people out there that do have problems with the PyEthernet dropping the connection, so thanks for your take on the situation!
Also good to hear the TTN configuration works better for you. I will work on putting this in the docs!
Thanks
